The protector 1 of the present embodiment shown in FIGS. 1 to 3, for example, has a surplus length of a part of the wiring material W that is wired to a slide seat, a slide door, or the like (not shown) mounted in a vehicle 200 such as an automobile. It is to be housed inside and protected as a part. In this embodiment, as shown in FIG. 6, a case where protector 1 is applied to slide seat 210 of vehicle 200 will be described. Specifically, the protector 1 includes a slide seat 210 arranged in a cabin 202 of the vehicle 200 so as to be slidable in a horizontal direction with respect to the vehicle body 201, and the vehicle body 201. It is assumed that they are arranged so that the lateral direction is along the vertical direction in between. The protector 1 of the present embodiment is arranged, for example, between an interior material 203 forming a part of the passenger compartment 202 and the vehicle body 201 so that the short side direction is along the vertical direction, and the longitudinal direction is the slide seat 210. are arranged along the sliding direction of The illustrated sliding direction of the slide seat 210 is, for example, along the longitudinal direction of the vehicle 200, but is not limited to this. The protector 1 of this embodiment includes a wiring member W, a main body portion 2 and an accommodation space portion 3 .

The wiring material W is a wire harness that supplies electric power to the electrical equipment E provided on the slide seat 210 in the vehicle 200, for example. The wiring member W is composed of, for example, a bundle of electric wires in which a plurality of electric wires are bundled, and a cylindrical (or tubular) outer covering covering the bundle of electric wires. This exterior material is, for example, a corrugated tube or the like. The wiring member W has relatively high flexibility and good bendability in the attached state in which the sheathing member is attached to the wire bundle. When the wiring member W of the present embodiment is in a state in which the sheathing member is attached to the wire bundle, the natural state (substantially linear state) in which no external force is applied to the bent state in which an external force is applied to the wire bundle W is bent. The bent portion is elastically deformed, and an elastic reaction force is generated in the bent portion to return to the original state. The wiring material W is partially housed in the interior of the protector 1 (accommodating space 3 ), and the part of the wiring material W slides along with the sliding movement of the slide sheet 210 in one of the sliding directions. It is introduced inside the protector 1 by pressing it, and is led out to the outside of the protector 1 along with the sliding movement in the other sliding direction. The wiring member W has one end electrically connected to the electrical component E provided on the slide seat 210 and the other end electrically connected to the battery B or the like mounted on the vehicle 200 . be.

The main body 2 is made of, for example, an insulating synthetic resin or the like. The body portion 2 extends in the longitudinal direction and has a pair of openings 2a and 2b in one of the longitudinal directions. The wiring material W is inserted through the openings 2a and 2b respectively in the accommodated state in which the wiring material W is partly accommodated inside the main body 2 (accommodating space 3). In the body portion 2, the wiring material W is introduced from one opening portion 2a as the slide sheet 210 slides in one of the sliding directions, and is arranged as the slide sheet 210 slides in the other sliding direction. The rope material W is led out from the opening 2a. The wiring material W is configured so that it can be taken in and out of the main body 2 through the opening 2a at one end in a stored state in which a part of the wiring material W is stored inside the main body 2. As shown in FIG. The wiring material W is in an accommodated state in which a part thereof is accommodated inside the main body 2, and the other end thereof is bound by a binding band or the like to a part of the main body 2 protruding outward from the opening 2b. This restricts taking in and out of the main body 2 through the opening 2b. The main body 2 is arranged so that the lateral direction thereof extends along the vertical direction, and attachment portions provided on the outer surface of the main body 2 are fastened to the vehicle body 201 by fastening members such as bolts. The body portion 2 is composed of an upper case 10 and a lower case 20 . The upper case 10 and the lower case 20 constitute the body portion 2 in a state of being assembled with each other.

As shown in FIGS. 3, 4A, and 4B, the upper case 10 is arranged on the Z1 direction side in the facing direction of the main body 2. As shown in FIGS. Upper case 10 has opening 11 , ceiling wall 12 , and side wall 13 . The opening 11 is formed at the end of the upper case 10 in the Z2 direction. The opening 11 is closed by the lower case 20 in an assembled state in which the upper case 10 is assembled to the lower case 20 (hereinafter simply referred to as an "assembled state"). The side wall portion 13 is erected from the outer peripheral end of the ceiling wall portion 12 toward the Z2 direction among the opposing directions.

As shown in FIG. 5, the ceiling wall portion 12 has a portion formed in an arcuate cross-sectional shape when viewed from the longitudinal direction so as to swell in the Z2 direction of the facing directions. The ceiling wall portion 12 has a wall surface 12a on the accommodation space portion 3 side in the assembled state. The wall surface 12a is formed to have an arcuate cross-sectional shape when viewed from the longitudinal direction so as to swell in the Z2 direction of the opposing directions. The wall surface 12a is curved in a convex shape toward the accommodation space portion 3 side. The wall surface 12a has the same arch shape extending in the Z2 direction when viewed from the longitudinal direction. In other words, the arcuate shape of the wall surface 12a bulging in the Z2 direction when viewed from the longitudinal direction is the same in the CC cross section, DD cross section, and EE cross section shown in FIG.

The lower case 20 is arranged on the Z2 direction side in the facing direction of the main body portion 2 . Lower case 20 has opening 21 , bottom wall 22 , and side wall 23 . The opening 21 is formed at the end of the lower case 20 in the Z1 direction. The opening 21 is closed by the upper case 10 in the assembled state. The side wall portion 23 is erected from the outer peripheral end of the bottom wall portion 22 toward the Z1 direction of the facing directions. Side wall portion 23 supports upper case 10 in the assembled state in which upper case 10 is assembled to lower case 20 . Upper case 10 and lower case 20 are locked by a locking structure.

As shown in FIG. 5, the bottom wall portion 22 faces the ceiling wall portion 12 in the assembled state. The bottom wall portion 22 has a portion formed in an arcuate cross-sectional shape when viewed from the longitudinal direction so as to bulge in the Z2 direction of the opposing directions. The bottom wall portion 22 has a wall surface 22a on the housing space portion 3 side in the assembled state. The wall surface 22a is formed to have an arcuate cross-sectional shape when viewed from the longitudinal direction so as to swell in the Z2 direction of the opposing directions. The wall surface 22a is curved in a concave shape toward the accommodation space portion 3 side. In this embodiment, the wall surface 22a and the wall surface 12a of the ceiling wall portion 12 are, as shown in FIG. The shape is arcuately formed so as to bulge in the same one of the opposing directions. The wall surface 22a has the same arch shape extending in the Z2 direction when viewed from the longitudinal direction. That is, the arcuate shape of the wall surface 22a bulging in the Z2 direction when viewed from the longitudinal direction is the same in the CC cross section, DD cross section, and EE cross section shown in FIG.

The housing space 3 is formed inside the main body 2 and communicates with the outside through a pair of openings 2a and 2b. The accommodation space 3 accommodates a portion of the wiring member W introduced from the outside through one opening 2a and led out through the other opening. When viewed from the facing direction of the body portion 2, the wiring member W routed in the housing space portion 3 has linear portions in a straight line state on both sides in the short direction, and the center side in the short direction. , a folded portion connecting the straight portions and in a folded state is arranged.

The straight portion Ws is a portion of the wiring member W accommodated in the accommodation space portion 3 in which a straight state is maintained along the longitudinal direction. When the slide sheet 210 is slid and taken in and out of the opening 2a, the straight portion Ws becomes longer in the longitudinal direction from one side to the other side, and becomes shorter in the other side.

The folded portion Wt is a portion of the wiring material W accommodated in the accommodation space portion 3 that is folded back in a U shape from one longitudinal direction of the main body portion 2 to the other. The folded portion Wt moves in the longitudinal direction as the slide sheet 210 slides, for example. Specifically, when the slide sheet 210 slides and is put in and taken out of the opening 2a, the folded portion Wt moves from one longitudinal direction to the other or vice versa.

When part of the wiring material W is drawn out from the housing space 3 through the opening 2a, the folded portion Wt is positioned at the R position in the longitudinal direction, as shown in FIGS. 3 and 4A. -> Q position -> P position. When the folded portion Wt moves in the order of R→Q→P and approaches the opening side, the straight portion Ws becomes shorter. On the other hand, when part of the wiring member W is introduced into the housing space 3 from the outside through the opening 2a, the folded portion Wt is arranged in the longitudinal direction from position P→position Q→R as shown in FIG. Move by position. When the folded portion Wt moves from P→Q→R and is separated from the openings 2a and 2b, the straight portion Ws becomes longer.

In the protector 1 and the vehicle wiring structure 100 of the present embodiment, the wall surface 12a of the main body 2 that contacts the folded portion Wt of the wiring material W is formed in an arcuate shape so as to bulge toward the folded portion Wt. As a result, the folded portion Wt is positioned in one of the opposing directions (for example, Z2 direction), a reaction force (elastic reaction force) is generated in the other of the opposing directions (Z1 direction). As a result, the contact state between the wall surface 12a and the folded portion Wt is maintained.

As described above, in the protector 1 of the present embodiment, the pair of opposing surfaces (the wall surface 12a and the wall surface 22a) constituting the main body 2 have cross-sectional shapes viewed from the longitudinal direction that are in the same direction of the opposing directions, e.g. It is formed in an arch shape so as to bulge in the Z2 direction.

With the above configuration, the wall surface 12a that bulges in the Z2 direction in an arc shape is arranged at each of the linear portions Ws of the wiring material W disposed at both ends in the short direction inside the main body 2 with respect to the folded portion Wt of the wiring material W. An external force is applied in the Z2 direction with respect to the imaginary line U (FIG. 7) passing through the central axis O. When the wall surface 12a contacts the folded portion Wt of the wiring material W and pushes it in the Z2 direction, the folded portion Wt is elastically deformed, and the reaction force (elastic reaction force) pushes back the wall surface 12a in the Z1 direction. , the folded portion Wt does not separate from the wall surface 12a with which it is in contact. As a result, even if the wall surface 12a vibrates due to vibrations during vehicle travel, the reaction force of the turned-up portion Wt of the wiring material W maintains the contact state between the wall surface 12a and the turned-up portion Wt. It is possible to suppress abnormal noise caused by striking 12a.

In addition, the vehicle wiring structure 100 of the present embodiment includes a slide seat in which the protector 1 is arranged in the vehicle interior 202 of the vehicle 200 so as to be slidable in the horizontal direction with respect to the vehicle body 201. 210 and the vehicle body 201, and arranged so that the lateral direction thereof extends along the vertical direction. In the protector 1, as the slide sheet 210 slides in one direction, the wiring member W is introduced from one opening 2a of the main body 2, and as the slide sheet 210 slides in the other direction, the wiring material W is introduced from the opening 2a. Then, the wiring material W is led out from the opening 2a. When the protector 1 is placed horizontally so that the facing direction is along the vertical direction, the folded portion Wt comes into contact with the wall surface 22a of the bottom wall portion 22 due to its own weight. Abnormal noise generated in can be suppressed. However, when the protector 1 is placed vertically so that the short side direction is along the vertical direction, the folded portion Wt does not come into contact with either of the wall surfaces 22a, 12a due to its own weight. may occur. Therefore, even if the protector 1 is placed vertically, even if the wall surface 12a in the protector 1, which expands toward the housing space 3, vibrates due to running vibrations, the wall surface 12a and the wiring material W are prevented from moving. can be maintained in contact with the folded portion Wt. As a result, it is possible to suppress the generation of abnormal noise due to vibration.

In the above-described embodiment, the wall surface 12a of the ceiling wall portion 12 has an arcuate cross-sectional shape when viewed from the longitudinal direction, and the wall surface 22a of the bottom wall portion 22 expands in the Z2 direction of the opposing directions. The cross-sectional shape when viewed from the longitudinal direction is formed in an arch shape so as to swell in the same direction as the Z2 direction, but is not limited to this. For example, the wall surface 12a has an arcuate cross-sectional shape when viewed from the longitudinal direction that swells in the Z1 direction opposite to the Z2 direction, and the wall surface 22a has a cross-sectional shape that is the same direction as the Z1 direction when viewed from the longitudinal direction. It may be formed in an arcuate shape so as to bulge out.

In the above-described embodiment, the wall surface 12a of the ceiling wall portion 12 and the wall surface 22a of the bottom wall portion 22 have the same arcuate shape bulging in the Z2 direction when viewed from the longitudinal direction, but the present invention is not limited to this. . FIG. 7 is a schematic diagram showing a cross section of a protector according to a modification of the embodiment, viewed from the longitudinal direction. The body portion 2 of the protector 1 shown in FIG. formed towards. The wall surface 12a according to the modified example of the embodiment swells from the wall surface 22a.

In the protector 1 according to the modification of the present embodiment, one wall surface 12a (first facing surface) of the pair of wall surfaces 12a and 22a is formed toward the housing space 3, and the other wall surface 22a (second facing surface) is formed toward the outside of the body portion 2 . The wall surface 12a protrudes from the wall surface 22a. This reduces or eliminates the clearance between the wire harness WH at the folded portion Wt and the wall surface 22a of the protector 1, thereby suppressing the amplitude or vibration of the wire harness WH at the folded portion Wt, thereby reducing abnormal noise. Alternatively, noise can be suppressed.

In addition, although the wiring material W is used as the wire harness WH in the above-described embodiment and modification, the protector in which the wiring material W is accommodated may be used as the wire harness WH.

In addition, in the above-described embodiment and modified example, the openings 2a and 2b are both formed on one side of the main body 2 in the longitudinal direction, but the present invention is not limited to this. For example, in the illustrated example, the opening 2a is formed at the tip of the wiring member insertion portion, which is a portion that protrudes in one longitudinal direction of the main body 2 and is folded back in the other direction. The opening 2a may be formed at a position spaced apart from the opening 2b in the longitudinal direction, extending toward the back side end in the other of the directions. For example, the wiring material insertion part may have a tip formed with an opening 2a extending near the center in the longitudinal direction of the main body 2, or extending from the center near the center to the far end side.
