JP 2005-102359 A

  However, in the thing disclosed in Patent Document 1, the movable end of the conductive path is in a state where it can freely move along the base member with the slide door closed. For this reason, if the harness disposed between the slide door and the vehicle body is stepped on or caught on any member while the slide door is being closed, the harness is greatly loosened between the slide door and the vehicle body. As a result, the movable end may move along the base member. If the harness is greatly slackened between the slide door and the vehicle body, the slack portion may interfere with the vehicle peripheral portion or may be pinched. Or, during traveling vibrations, there is a possibility that an interference sound or a hitting sound may be generated between the slack portion and the vehicle peripheral portion.

  In view of the above, an object of the present invention is to suppress the interference of the conductive path disposed between the slide door and the vehicle body with its peripheral parts, particularly when the slide door is closed.

In order to solve the above-described problem, a conductive path device for a sliding door according to a first aspect is a conductive path device for a sliding door that electrically connects a vehicle body side electrical component and a sliding door side electrical component, A harness guide rail member disposed on the slide door, a slider member disposed so as to be movable along the harness guide rail member, one end portion is coupled to the slider member, and the other end portion is A conductive path in the slide door that is electrically connected to the electrical component on the slide door side, and one end is electrically connected to the electrical component on the vehicle body side, and the other end is coupled to the slider member so that the inside of the slide door A conductive path between the slide doors connected to the one end of the conductive path, and following the opening and closing of the slide door, the conductive path in the slide door and the slide door between the vehicle bodies The slider member is disposed to be able to reciprocate along the harness guide rail member while bending and deforming the road, and the sliding door body bending operation guide member is externally mounted on the slide door body-to-body conductive path, and the slide One end portion of the door inter-body bending operation guide member is attached to the vehicle body via a vehicle body side mounting member, and the other end portion of the sliding door inter-body bending operation guide member is connected to the slider member. A member supports the one end of the sliding door interbody bending operation guide member so as to be able to swing as the sliding door is opened and closed, and abuts against the slider member with the sliding door closed. Te, in which the stopper member for restricting the movement of the slider member in the direction of loosening of the sliding door body Mashirube path occurs is provided

It has a pair of guide side plate part.

A conductive path device for a sliding door according to a third aspect is a conductive path device for a sliding door according to the first or second aspect, wherein the stopper member is halfway in the longitudinal direction of the harness guide rail member. It is made to be the member formed by carrying out the plastic deformation of one part in convex shape .

  The conductive path device for a sliding door according to a fourth aspect is the conductive route device for a sliding door according to the first or second aspect, wherein the stopper member is attached to the harness guide rail member as a separate member. It is a fixed member.

This is a coil spring disposed in the.

A conductive path device for a sliding door according to a sixth aspect is a conductive path device for a sliding door according to any one of the first to fifth aspects, and the sliding door interbody bending operation guide member includes: wherein a sliding door body Mashirube armored corrugated tube path, those.

According to the conductive path device for a sliding door according to the first aspect, the state closing the sliding door, the slider member abuts the slider in a direction loosening is caused in the sliding door body Mashirube path Since the stopper member for restricting the movement of the member is provided, it is difficult for the slack in the conductive path between the slide door bodies to occur when the slide door is closed. For this reason, it can suppress that the electrical conduction path between sliding door bodies interferes with the peripheral parts.

  Like the conductive path device for a sliding door according to the second aspect, the harness guide rail member has a pair of guide side plate portions having substantially the same cross-sectional shape along the longitudinal direction. It can respond to each car model by changing the. In such a case, as the length dimension of the pair of guide side plate portions, a value corresponding to the dimension of the slide door to be attached is set, and a value corresponding to the required moving distance of the slider member is not necessarily set. . Therefore, it is preferable to provide the stopper member for such a harness guide rail member.

According to the third and fourth aspects, it is possible to restrict the movement of the slider member by a stopper member.

According to a fifth aspect, after which it is possible to restrict the movement of the slider member by the stopper member, the stopper member, because it has an elastic member for urging the contact direction to the slider member, the sliding door is over When the actuator moves more than the original closed position due to a stroke or the like, or when a tensile force acts on the slide door inter-vehicle conductive path, the elastic member is compressed and deformed, thereby The slider member can be moved in a direction in which the road is slack. Thereby, it can suppress that excessive tension | tensile_strength acts on the conductive path between slide door vehicle bodies.

  According to the sixth aspect, the conductive path between the sliding doors can be protected by a relatively simple configuration using a corrugated tube. In this case, since the corrugated tube is weakly restricted in the bending direction, the conductive path between the sliding door bodies is likely to sag. Thus, as described above, it is effective to provide the stopper member with respect to the harness guide rail member so as not to cause a large slack in the conductive path between the sliding doors.

<Application examples>
First, for convenience of explanation, the relationship between the vehicle body to be applied and the sliding door will be described. 1 is a schematic plan view showing the relationship between the vehicle body 12 and the slide door 14, FIG. 2 is a schematic view taken along line II-II in FIG. 1, and FIG. 3 is a schematic view taken along line III-III in FIG. is there. For convenience of explanation, the description may be made with reference to the front-rear direction, the left-right direction, and the up-down direction of the vehicle.

  The automobile 10 includes a vehicle body 12 and a slide door 14 provided on one side of the vehicle body 12. On one side of the vehicle body 12, a boarding opening 13 through which people can get on and off is provided. The slide door 14 is movable between a position where the boarding port 13 is closed (closed position P1) and a position where the boarding port 13 is opened (open position P2) by a slide support mechanism including a guide rail (not shown). It is supported by.

  More specifically, the slide door 14 is movable between the closed position P1 on the front side of the vehicle and the open position P2 on the rear side of the vehicle by moving mainly in the vehicle front-rear direction. When the slide door 14 moves from the closed position P1 to the open position P2, the slide door 14 also moves outward in the vehicle width direction in order to avoid interference with the vehicle body 12. At this time, the movement amount of the lower end portion of the slide door 14 in the vehicle width direction is set to be larger than the movement amount of the upper end portion of the slide door 14. Thereby, when the lower end part of the slide door 14 moves to the open position P2 from the closed position P1, it moves also upwards (for example, about 10-40 mm).

<Overall configuration of conductive path device for sliding door>
Next, the overall configuration of the conductive path device for the sliding door will be described. 4 is a schematic perspective view showing the overall configuration of the conductive path device 20, FIG. 5 is a schematic side view showing the overall configuration of the conductive path device 20, and FIG. 6 is a schematic plan view showing the conductive path device 20. . 4 to 6, the state when the slide door 14 is in the closed position P1 is denoted by reference numeral P1, and the state when the slide door 14 is in the open position P2 is denoted by reference numeral P2.

  The conductive path device 20 includes various electrical components (for example, a power window drive device, a door lock drive device, and various switches) installed in the slide door 14 and various electrical components (various operation switches, An electronic control unit, a battery, and the like), and includes a first conductive path mechanism unit 30 and a second conductive path mechanism unit 50.

  The first conductive path mechanism unit 30 includes a slide door wire harness 32 as a slide door conductive path and a slide door guide rail device 40.

  The guide rail device 40 in the slide door is a member that linearly guides one end of the wire harness 32 in the slide door following the opening / closing operation of the slide door 14, and includes a harness guide rail member 42, a slider member 46, and the like. have.

  FIG. 7 is a fragmentary perspective view showing the harness guide rail member 42 and the slider member 46. As shown in FIGS. 4 to 7, the harness guide rail member 42 is a member that is attached and fixed to the slide door 14 along the longitudinal direction of the vehicle, and the slider member 46 moves along the harness guide rail member 42. It is a member arranged in a possible manner.

  More specifically, the harness guide rail member 42 has a pair of guide side plate portions 43 and a spacer member 44. The guide side plate portion 43 is formed in a substantially rectangular plate shape. The spacer member 44 is a member that connects and supports the pair of guide side plate portions 43 in a substantially parallel posture with a gap therebetween. Here, the spacer member 44 is formed in a substantially bar-like member, and the guide side plate portion 43 and the spacer member 44 are in a state where the spacer member 44 is interposed between both ends of the pair of guide side plate portions 43. The pair of guide side plate portions 43 are connected and supported in a substantially parallel posture by fixing them with screws.

  In addition, a pair of elongated protrusion-like rail portions 43 a are formed along the longitudinal direction of the guide side plate portion 43 at the intermediate portion in the width direction of one main surface of the guide side plate portion 43. The pair of guide side plate portions 43 are arranged and supported so as to protrude inward of the pair of guide side plate portions 43 in a state where the pair of guide side plate portions 43 are connected and supported in a substantially parallel posture as described above. Yes. Thus, the structure which linearly guides the slider member 46 with the structure which a pair of rail part 43a opposes with a space | interval is implement | achieved.

  The guide side plate portion 43 is formed as a member having substantially the same cross-sectional shape along the longitudinal direction. Here, when the harness guide rail member 42 is formed into a member having substantially the same cross-sectional shape along the longitudinal direction, the basic components excluding the post-processed or retrofitted portion are the The case where it forms in the shape which has the same cross-sectional shape along a longitudinal direction is included. Here, the harness guide rail member 42 is formed by appropriately cutting a length using an extruded member such as an aluminum alloy as a base material. Therefore, it has the same cross-sectional shape along the longitudinal direction except for a part to be post-processed as will be described later.

  An attachment piece 42P is attached and fixed to the outer surface of one guide side plate portion 43 via a screw or the like. The harness guide rail member 42 is attached and fixed to the lower end portion of the slide door 14 and the like in a posture along the vehicle front-rear direction via the attachment piece 42P and the like.

  Furthermore, a harness guide fixing member 48 is attached to the upper part of the intermediate portion in the longitudinal direction of the harness guide rail member 42. The harness guide fixing member 48 is formed as a plate-like member protruding above the harness guide rail member 42, and at a fixed position above the harness guide rail member 42, the wire harness 32 in the sliding door and the bending in the sliding door are formed. The other end portion of the operation guide member 36 is fixedly supported. The harness guide fixing member 48 is formed with a space communicating with the space between the pair of guide side plate portions 43, and a slide door bending operation guide member 36, which will be described later, is arranged so as to be able to be bent in the space. It is installed.

  Note that the harness guide rail member 42 as described above has an advantage that it is easy to manufacture one having an arbitrary length in accordance with the size, shape, and the like of the slide door 14 serving as an attachment mode. For example, when the longitudinal length of the slide door 14 is long, the extruded member as a base material is cut with a relatively long dimension, and then the spacer member 44 and the attachment piece 42P are attached at an appropriate position. Good. Further, for example, when the front and rear length of the slide door 14 is short, the extruded member as a base material is cut with a relatively short dimension, and then the spacer member 44 is attached at an appropriate position, the attachment piece 42P is attached, and the like. Just do it. As described above, by appropriately adjusting the cutting length of the extrusion member serving as the base material, the harness guide rail member 42 can be manufactured by adjusting the length dimension thereof, and can easily cope with a plurality of vehicle types.

  Further, the slider member 46 can be disposed between the pair of guide side plate portions 43, and the protrusions 46a that can be disposed between the pair of rail portions 43a are provided in the vehicle front-rear direction on both sides. It is formed in the member formed along. Then, by arranging the slider member 46 between the pair of guide side plate portions 43 while arranging the respective protrusions 46a between the pair of rail portions 43a, the slider member 46 is attached to the harness guide rail member 42. It is supported so as to be movable along the longitudinal direction.

  Further, a slide door side connecting portion 47a capable of connecting the slide door bending operation guide member 36 is formed at the upper end portion of the slider member 46, and the sliding door body bending operation is formed at the lower end portion of the slider member 46. A vehicle body side connecting portion 47b to which the guide member 60 can be connected is formed (see FIG. 7). Then, the sliding door inner bending motion guide member 36 is connected to the sliding door side connecting portion 47 a, whereby the sliding door inner wire harness 32 is connected to the slider member 46.

  The wire harness 32 in the sliding door is configured by bundling a plurality of electric wires in a linear shape, and is itself a linear material that can be freely bent.

  In addition, the sliding door inner wire harness 32 is provided with an inner sliding door bending operation guide member 36, whereby the sliding door inner wire harness 32 is bent in one plane (a plane substantially parallel to the side of the vehicle body). Be guided to do.

  More specifically, the sliding door bending motion guide member 36 includes a plurality of link members 37 having a pair of side pieces supported at intervals, and each link member 37 is arranged around a predetermined axis. By being connected so as to be rotatable, a linear member that can be bent in one plane as a whole is formed. Further, in the sliding door bending operation guide member 36, a harness housing space is formed along the longitudinal direction of the sliding door wire harness 32, so that the sliding door wire harness 32 can be inserted into the sliding door bending motion guide member 36. It is inserted into the harness housing space. Thereby, the wire harness 32 in the slide door is guided so as to be able to bend in one plane.

  One end of the sliding door bending operation guide member 36 is connected to the slider member 46 through a sliding door side connecting portion 47a between the pair of guide side plate portions 43. The other end portion of the sliding door bending operation guide member 36 is fixedly attached to the upper end portion of the harness guide fixing member 48 through a fitting structure, a screwing structure, or the like. One end portion of the wire harness 32 in the slide door is electrically connected to the other end portion of the wire harness 52 between the slide door bodies to be described later via the slider member 46 via the slide door side connecting portion 47a, and slides. The other end portion of the in-door wire harness 32 is electrically connected to the electrical component on the slide door side from the fixed portion via another wire harness, electric wire, and the like.

  The second conductive path mechanism unit 50 is provided between the vehicle body 12 and the slide door 14, and includes a slide door inter-vehicle wire harness 52 and a slide door inter-vehicle bending operation guide member 60. As described above, the wiring member provided between the vehicle body 12 and the slide door 14 may be referred to as a transition wiring.

  As shown in FIG. 4 to FIG. 6, the slide door inter-vehicle wire harness 52 is configured by bundling a plurality of electric wires in a linear shape, and is itself flexibly bent in the same manner as the wire harness 32 in the slide door. It is considered as a possible linear material.

  The sliding inter-vehicle body bending operation guide member 60 is externally mounted on the sliding door inter-vehicle body wire harness 52 and is configured to guide the bending operation of the sliding door inter-vehicle body wire harness 52. Here, the sliding door body bending motion guide member 60 is configured by a bellows-like corrugated tube through which the sliding door body wiring harness 52 can be inserted. The sliding door body bending movement guide member 60 restricts the sliding door body wiring harness 52 to a certain degree in a state where the sliding door body wiring harness 52 is inserted into the sliding door body bending harness 52, and thus the sliding door body bending harness 52 is somewhat restricted. The inter-wire harness 52 has a role of preventing drooping between the vehicle body 12 and the slide door 14.

  However, as the sliding door interbody bending operation guide member 60, like the above-described sliding door bending operation guide member 36, a plurality of link members 37 are linearly connected mainly so as to be capable of bending operation within a predetermined plane. It may be.

  A vehicle body side mounting member 66 is connected to one end of the sliding door interbody bending operation guide member 60. Then, the vehicle body side attachment member 66 is attached to the vehicle body by a screwing structure or an engagement structure, so that one end of the sliding door interbody bending operation guide member 60 is attached to the vehicle body. Further, the other end of the sliding door interbody bending operation guide member 60 is connected to the vehicle body side connecting portion 47 b of the slider member 46. The sliding door interbody bending operation guide member 60 and the vehicle body side connecting portion 47b support each end of the sliding door interbody bending operation guide member 60 so as to be rotatable about a substantially vertical axis. Each end of the sliding door interbody bending operation guide member 60 is supported so as to be swingable around a substantially vertical axis.

  One end of the sliding door inter-vehicle wire harness 52 inserted into the sliding door inter-vehicle bending operation guide member 60 is connected to the vehicle body side electrical equipment from the vehicle body side mounting member 66 via another wire harness or electric wire. One end portion of the wire harness 52 between the slide doors is electrically connected to the other end portion of the wire harness 32 in the slide door via the inside of the slider member 46 via the vehicle body side connecting portion 47b. It is connected to the.

  But the wire harness 52 between sliding door vehicle bodies and the wire harness 32 in slide door may be one continuous wire harness.

  In addition, the conductive path device for the sliding door follows the opening and closing of the sliding door 14 and bends and deforms the wire harness 32 within the sliding door and the wire harness 52 between the sliding doors, and the slider member 46 is harness guide rail. It is configured to be reciprocally movable along the member 42.

  In other words, in a state where the slide door 14 is in the closed position P <b> 1, one end of the slide door inter-vehicle wire harness 52 on the vehicle body side is on the vehicle rear side with respect to the harness guide rail member 42. For this reason, the slider member 46 is pulled toward the vehicle rear side by the sliding door inter-vehicle wire harness 52 and is positioned on the vehicle rear side of the harness guide rail member 42. In this state, the in-slide door wire harness 32 is bent in a substantially J shape in which the linear portion on one end side (lower side) is shorter than the linear portion on the other end side (upper side) ( 4 and 5). Moreover, the wire harness 52 between the sliding doors is in a state extending along the vehicle front-rear direction while being slightly curved between the slider member 46 on the sliding door 14 side and the vehicle body side mounting member 66 on the vehicle body 12 side. (See FIGS. 4 to 6).

  When the sliding door 14 is opened from the above state, the sliding door 14 moves mainly in the vehicle longitudinal direction and the vehicle width direction. As a result, one end of the sliding door inter-vehicle wire harness 52 on the vehicle body side moves relative to the harness guide rail member 42 toward the vehicle front side. Then, the slider member 46 is pulled to the vehicle front side by the sliding door inter-vehicle wire harness 52 and moves to the vehicle front side of the harness guide rail member 42. Accordingly, the sliding door inner wire harness 32 bends along a plane substantially parallel to the side surface of the vehicle body under the guide state by the sliding door inner bending operation guide member 36, passes through a substantially U-shaped shape, and reaches its one end side (lower The straight line portion on the side) is longer than the straight line portion on the other end side (upper side), and is bent in a substantially J shape (see FIGS. 4 and 5). In addition, under the guide state by the sliding door interbody bending operation guide member 60, the sliding door interbody wire harness 52 bends mainly in a plane along the floor surface, passes through a substantially S-shape, and then slides on the slide door 14 side. It will be in the state extended while slightly curving between the member 46 and the vehicle body side attachment member 66 by the side of the vehicle body 12 (refer FIGS. 4-6).

  As described above, as the slide door 14 is opened and closed, the lower end portion of the slide door 14 is also displaced in the vertical direction. Then, along with the vertical displacement of the slide door 14, the sliding door interbody wire harness 52 is also bent in the vertical direction while being guided by the sliding door interbody bending operation guide member 60.

  FIG. 8 is a schematic perspective view showing the harness guide rail member 42, the slider member 46, and the sliding door inter-vehicle wire harness 52 in a state where the sliding door 14 is closed (closed position P1).

  As shown in the figure, the slider member 46 is in the rear position of the harness guide rail member 42 with the slide door 14 closed. However, since the harness guide rail member 42 itself is manufactured according to the longitudinal length of the slide door 14, the shape of the built-in portion, and the like, the slider member 46 in the harness guide rail member 42 is in a state where the slide door 14 is closed. A surplus length portion 42B is present on the rear side of the expected position. For this reason, the slider member 46 can be moved further rearward with the slide door 14 closed. Further, when the sliding door inter-vehicle wire harness 52 is stepped on by a person, for example, when the sliding door 14 is closed, or when it interferes with surrounding objects, the sliding door inter-vehicle wire harness 52 may be pulled greatly. . Then, the slider member 46 moves beyond the predetermined position to the extra length portion 42B side, and a large curved portion or slack is generated in the sliding door inter-vehicle wire harness 52. In order to suppress such a large curved portion or slack, a stopper member 70 described below is provided.

  FIG. 9 is a partially broken side view showing the stopper member 70. The stopper member 70 is in contact with the slider member 46 in a state where the slide door 14 is closed and is in the closed position P1, and the slider member 46 in the direction in which the slide door inter-vehicle wire harness 52 is slackened (rear of the vehicle). The movement is restricted.

  More specifically, the stopper member 70 is provided between one side end portions (end portions on the vehicle rear side) of the pair of guide side plate portions 43. The stopper member 70 is a member having a thickness dimension that can be disposed between the pair of guide side plate portions 43. The stopper member 70 extends along the stopper fixing portion 72 having a mounting hole 72 h into which the spacer member 44 can be inserted and the pair of rail portions 43 a. And an abutting portion 74 that extends. The vertical dimension of the contact part 74 is smaller than the vertical dimension of the stopper fixing part 72, and accordingly, a recess 70 h is formed above the center of the pair of guide side plate parts 43 in the stopper member 70. A groove (not shown) in which the rail portion 43a can be disposed is formed on both side surfaces of the stopper member 70. The stopper member 70 is attached and fixed at a predetermined position on one end of the harness guide rail member 42 by disposing the rail portion 43a in the groove and inserting the spacer member 44 through the attachment hole 72h. ing.

  In the state where the slide door 14 is in the closed position P1 in the normal state, the tip end portion of the contact portion 74 of the stopper member 70 is in a state where the slider member 46 is disposed at the planned rear position in the harness guide rail member 42. The slider 46 is in contact with the slider member 46. That is, the stopper member 70 contacts the slider member 46 at a position inside the both end portions of the harness guide rail member 42. At this time, the sliding door bending operation guide member 36 extending from the slider member 46 is bent in a substantially J shape as described above in a state where it is disposed in the recess 70h. Here, the estimated rear position of the slider member 46 refers to a person or person with respect to the sliding door interbody bending operation guide member 60 when the sliding door 14 is opened and closed in a state where the sliding door 14 is in the closed position P1. The slider member 46 should be disposed when the sliding door interbody bending operation guide member 60 bends following the opening and closing operation of the sliding door 14 in a natural state without any external force acting on the peripheral members or the like. Says the position.

  According to the conductive path device 20 for a sliding door configured as described above, the stopper member 70 abuts on the slider member 46 in a state where the sliding door 14 is closed and moved to the closed position P1, and the sliding door is bent between the vehicle bodies. The movement of the slider member 46 in the direction (rear of the vehicle) in which the guide member 60 and the sliding door inter-vehicle wire harness 52 are slackened is restricted. Therefore, even when the sliding door interbody bending operation guide member 60 is stepped on by a person or when the sliding door 14 is in contact with the peripheral members during the closing of the sliding door 14, the sliding door 14 is moved to the closed position P1. Then, the slider member 46 is regulated so as to be disposed at the predetermined rear position. Therefore, it is difficult for the sliding door body bending movement guide member 60 and the sliding door body wire harness 52 to be largely loosened. This makes it difficult for the sliding door interbody bending operation guide member 60 and the sliding door interbody wire harness 52 to be sandwiched between other members in a state in which the sliding door 14 is closed. Interference sound, hitting sound, and the like are suppressed between the interbody bending operation guide member 60 and the sliding door interbody wire harness 52 and other peripheral members.

  Such a stopper member 70 is particularly effective when applied to the harness guide rail member 42 having a pair of guide side plate portions 43 having substantially the same cross-sectional shape along the longitudinal direction. That is, by using the harness guide rail member 42 having a pair of guide side plate portions 43 having substantially the same cross-sectional shape along the longitudinal direction, the length of the guide side plate portion 43 is adjusted by appropriately adjusting the cutting position of the base material. By adjusting, it becomes possible to easily cope with a plurality of vehicle types. In such a case, the length dimension of the pair of guide side plate portions 43 is set to a value corresponding to the dimension and location of the slide door to be attached rather than the movement range of the slider member 46. As a result, the length dimension of the harness guide rail member 42 may be set larger than the moving distance of the slider member 46. Then, since the slider member 46 can further move from the planned rear position, the sliding door inter-vehicle wire harness 52 is likely to be loosened. Therefore, by providing the stopper member 70 as described above and restricting the movement of the slider member 46 from the expected rear position, the slack of the wire harness 52 between the sliding doors can be effectively suppressed.

  In addition, when a corrugated tube is used as the sliding door body bending motion guide member 60, the sliding door body wiring harness 52 can be protected by a relatively simple configuration, but the corrugated tube itself is basically in a free direction. Therefore, the wire harness 52 between the sliding door bodies tends to sag. Therefore, in such a case, by providing the stopper member 70 on the harness guide rail member 42, it is possible to prevent the slack door inter-vehicle wire harness 52 from being greatly slackened.

  The configuration of the stopper member that restricts the movement of the slider member 46 is not limited to the example described in the above embodiment.

  For example, as in the modification shown in FIG. 10, the stopper member 70 </ b> B may be formed by plastically deforming a part of the harness guide rail member 42.

  More specifically, in the example shown in FIG. 10, the stopper member 70 </ b> B is formed by plastically deforming part of the rail portions 43 a of the pair of guide side plate portions 43 in a convex shape. The stopper member 70B may be formed by press working or the like. Accordingly, when the slider member 46 moves to the predetermined rear position, the slider member 46 comes into contact with the stopper member 70B. Thereby, the further movement (movement to the vehicle rear side) of the slider member 46 is suppressed, and the same effect as the above is obtained.

  Thus, the stopper member does not need to be a member that is attached and fixed as a separate member to the harness guide rail member 42 as in the above embodiment, and is formed by deforming a part of the harness guide rail member 42. It may be a member.

  In particular, according to the present modification, the guide side plate portion 43 only needs to be processed, and it is not necessary to prepare a separate member separately. Therefore, it is possible to reduce the number of parts and facilitate assembly.

  In addition, the process location with respect to the harness guide rail member 42 is not restricted to the said example, A part other than the rail part 43a among a pair of guide side board parts 43 is comprised as an uneven | corrugated process, or a cut-and-raft process, and is comprised as a stopper member. May be.

  Further, for example, as in the modification shown in FIG. 11, the stopper member 70 </ b> C may include a coil spring 76 </ b> C as an elastic member that urges the slider member 46 in the contact direction.

  More specifically, the stopper member 70C has a stopper main body 71C and a coil spring 76C. The stopper main body portion 71C is a member having a thickness dimension that can be disposed between the pair of guide side plate portions 43, and includes a stopper fixing portion 72C having a mounting hole 72Ch through which the spacer member 44 can be inserted, and a pair of rail portions 43a. It has a stopper main body 71C having an extending portion 74C extending along. That is, the stopper main body 71C has a shape in which the length of the contact portion 74 of the stopper member 70 is shortened. In the same manner as the stopper member 70, the stopper main body 71 </ b> C is attached and fixed at a predetermined position at one end of the harness guide rail member 42.

  A coil spring 76C is disposed along the moving direction of the slider member 46 (that is, the longitudinal direction of the harness guide rail member 42) at the distal end portion of the extending portion 74C. The coil spring 76C can be expanded and contracted along the moving direction of the slider member 46, and in a natural length state, the coil spring 76C is disposed so that the abutting portion on the tip side can abut on the slider member 46 moved to the predetermined rear position. Has been. The coil spring 76 </ b> C may be externally fitted to a guide rod that can expand and contract along the moving direction of the slider member 46. Moreover, the contact part which is another member may be provided in the front-end | tip part of the coil spring 76C.

  When the slider member 46 moves to the predetermined rear position, the slider member 46 comes into contact with the tip of the coil spring 76C of the stopper member 70C. Thereby, the further movement (movement to the vehicle rear side) of the slider member 46 is suppressed, and the same effect as the above is obtained. Further, in the state where the slide door 14 is moving or in the state where the slide door 14 is moved to the closed position P1, a tension force acts on the slide door interbody bending operation guide member 60, and a force which compresses and deforms the coil spring 76C acts. As a result, even if the slider member 46 moves further to the vehicle rear side than the planned rear position, when the force is removed, the slider member 46 returns to the planned rear position by the elastic restoring force of the coil spring 76C. For this reason, the slack of the sliding door interbody bending operation guide member 60 and the sliding door interbody wire harness 52 is eventually removed.

  In particular, in this modification, when the slide door 14 moves more than the original closed position P1 due to an overstroke or the like, or when the slide door interbody bending operation guide member 60 and the slide door interbody wire harness 52 are provided. This is effective when a temporary tensile force is applied. That is, in such a case, the sliding door inter-vehicle body bending operation guide member moves in a direction in which the coil spring 76C is compressed and deformed and the sliding door inter-vehicle body wire harness 52 is slackened. 60 and the sliding door inter-vehicle wire harness 52 can be given a temporary slack so that an excessive tensile force acting on the sliding door inter-vehicle wire harness 52 and the like can be absorbed and suppressed.

  Note that the fully closed side overstroke of the slide door 14 means that when the slide door 14 is closed vigorously, the slide door 14 is inherently deformed while elastically deforming the elastic seal between the vehicle body 12 and the slide door 14. This is a phenomenon that slightly exceeds the closed position P1.
