Description

  The present invention relates to a door lock device for a vehicle.

  Generally, in a door lock device for a vehicle, a link lever is connected to an open lever, an open rod connected to the door handle is connected to the open lever, and the operation of the door handle is routed from the open lever to the link lever. The latch mechanism is released. The link lever is locked or unlocked by the lock lever. That is, when the link lever is locked, the operation of the door handle is invalidated by the link lever and the latch mechanism cannot be released. On the other hand, when the link lever is unlocked, the operation of the door handle is enabled by the link lever and the latch mechanism can be released.

  Conventionally, as a configuration for connecting a link lever and an open rod to an open lever, a connecting portion is provided on the open lever so as to be swingable, and the link lever is locked to the connecting portion. Further, a synthetic resin clip is attached to the connecting portion, and the long hole of the open rod is locked to the clip. The long hole of the open rod is a relief hole that prevents the operation of either the outside door handle or the inside door handle from being transmitted to the other (for example, see Patent Document 1).

  However, in the conventional door lock device, a connecting portion is interposed in the open lever so that the link lever can swing, and a clip is interposed in order to reduce the sliding resistance of the long hole of the open rod. It is. That is, since a connecting portion and a clip are required in addition to the open lever, the link lever, and the open rod, the number of parts increases and the size of the apparatus becomes a problem.

  In view of the above circumstances, an object of the present invention is to provide a door lock device that can reduce the number of parts in connection with an open lever, a link lever, and an open rod, and can reduce the size of the device.

  In order to achieve the above object, a door lock device according to claim 1 of the present invention includes a link lever coupled to an open lever, and an open rod connected to the door handle coupled to the open lever. In the door lock device that releases the latch mechanism by passing the operation from the open lever to the link lever, the first connecting shaft that swingably engages the link lever with the open lever, and the open rod with respect to the link lever Are integrally provided on the second connecting shaft and the link lever which are slidably engaged.

  A door lock device according to a second aspect of the present invention is the door lock device according to the first aspect, wherein the first connecting shaft is provided on one surface of the link lever, and the second connecting shaft is provided on the other surface of the link lever. It is characterized by being.

  According to a third aspect of the present invention, the door lock device according to the first or second aspect is characterized in that the first connecting shaft and the second connecting shaft are arranged coaxially.

  A door lock device according to a fourth aspect of the present invention is the door lock device according to any one of the first to third aspects, wherein the link lever is formed of a synthetic resin material with a first connection shaft and a second connection shaft. It is characterized by that.

  The door lock device according to the present invention includes a first connecting shaft that slidably engages the link lever with the open lever, and a second connecting shaft that slidably engages the open rod with the link lever. The link lever is provided integrally. As a result, the number of parts can be reduced with respect to the connection of the open lever, the link lever, and the open rod, and the apparatus can be downsized.

  Furthermore, the first connecting shaft is provided on one surface of the link lever, and the second connecting shaft is provided on the other surface of the link lever. As a result, since the connecting portions of the open lever, the link lever, and the open rod are concentrated on one surface and the other surface in the area of the surface of the link lever, the apparatus can be reduced in size.

  Further, the first connecting shaft and the second connecting shaft are arranged coaxially. As a result, it is possible to reduce the transmission load of the operation force that passes the door handle operation from the open lever to the link lever.

  Further, the link lever is formed of a synthetic resin material with a first connecting shaft and a second connecting shaft. As a result, sliding resistance with the open lever and the open rod can be reduced, and the weight of the device can be reduced.

  Exemplary embodiments of a door lock device according to the present invention will be explained below in detail with reference to the accompanying drawings. Note that the door lock device in the present embodiment holds the door in a closed state with respect to the vehicle, for example, and further locks the closed state of the door.

  1 is a front view showing an example of a door lock device according to the present invention, FIG. 2 is a rear view of the door lock device shown in FIG. 1, FIG. 3 is a left side view of the door lock device shown in FIG. It is a right view of the door lock apparatus shown in FIG.

  The door lock device illustrated in the present embodiment is provided at a door of a front hinge disposed on the right front seat of a four-wheeled vehicle. As shown in FIGS. 1 to 4, in the door lock device, a latch mechanism and a lock mechanism are provided with a base plate 1 as a base. The base plate 1 is formed, for example, by bending or punching a sheet metal, and is bent at a substantially right angle so that the substrate 11 faces the front side (the front side of the vehicle body) and projects from the side of the substrate 11 to the front side. The main cross section is substantially L-shaped.

  As shown in FIGS. 2 to 4, the latch mechanism has a latch body (accommodating portion) 21 formed of synthetic resin. As shown in FIG. 2, the latch body 21 has an opening 21 a on the back surface (one surface), accommodates the latch 22 and the ratchet 23 from the opening 21 a, and closes the opening 21 a with a cover plate 24. . In addition, the latch body 21 has a horizontal cutout groove 211 extending in a substantially horizontal direction toward the vehicle interior side at a position substantially at the center. The front surface (the other surface) of the latch body 21 is attached to the substrate 11 of the base plate 1. The cover plate 24 has a horizontal cutout groove 241 as in the latch body 21.

  The latch 22 and the ratchet 23 are for meshing and holding the striker S (see FIGS. 5 to 7) provided on the vehicle main body side of the four-wheeled vehicle, as in the prior art.

  As shown in FIGS. 5 to 7, the latch 22 is positioned above the horizontal cutout groove 211 of the latch body 21 via a latch rotating shaft 25 extending substantially horizontally along the front-rear direction of the vehicle body. And has a meshing groove 221, a hook portion 222, and a locking portion 223.

  The engagement groove 221 is formed from the outer peripheral surface of the latch 22 toward the latch rotation shaft 25 and is formed to have a width that can accommodate the striker S.

  The hook portion 222 is a portion located on the indoor side of the engagement groove 221 when the latch 22 is rotated about the latch rotation shaft 25 and the engagement groove 221 is opened downward. As shown in FIG. 7, the hook portion 222 stops at a position (full latch position) that crosses the horizontal cutout groove 211 of the latch body 21 when the latch 22 is rotated counterclockwise. On the other hand, as shown in FIG. 5, the hook portion 222 stops at a position (open position) where the horizontal cutout groove 211 is opened when the latch 22 is rotated clockwise.

  The locking portion 223 is a portion located on the outdoor side of the engagement groove 221 when the latch 22 is rotated about the latch rotation shaft 25 and the engagement groove 221 is opened downward. As shown in FIG. 5, the locking portion 223 crosses the horizontal cutout groove 211 when the latch 22 is rotated clockwise, and gradually toward the back (outdoor) of the horizontal cutout groove 211. It is configured to stop while tilting upward. Although not clearly shown in the drawing, a latch spring is provided between the latch 22 and the latch body 21 to constantly urge the latch 22 clockwise in FIGS.

  The ratchet 23 extends substantially horizontally along the front-rear direction of the vehicle body at a position below the horizontal cutout groove 211 of the latch body 21 and on the indoor side of the latch rotation shaft 25. And has an engaging portion 231 and an action portion 232.

  The engaging portion 231 is a portion that extends radially outward from the ratchet rotation shaft 26 toward the outdoor side. When the ratchet 23 is rotated counterclockwise in FIGS. 5 to 7, the engaging portion 231 can be engaged with the hook portion 222 and the locking portion 223 of the latch 22 described above via its end face. It is.

  The action part 232 is a part extending radially outward from the ratchet rotation shaft 26 toward the indoor side. The action portion 232 is connected to the ratchet lever 27. The ratchet lever 27 is provided on the front side of the base plate 1 of the base plate 11 (the front side of the vehicle body) and rotates around the axis of the ratchet rotation shaft 26. That is, the ratchet 23 and the ratchet lever 27 are integrally rotated with each other around the axis of the ratchet rotation shaft 26. Although not shown in the drawing, between the ratchet 23 and the latch body 21, a ratchet spring that constantly biases the ratchet 23 (and the ratchet lever 27) counterclockwise in FIGS. 5 to 7. Is provided.

  In the latch mechanism configured as described above, when the door is in an open state with respect to the vehicle body, the latch 22 is disposed in the open position as shown in FIG. When the door is closed from this state, the striker S provided on the vehicle body side comes into contact with the locking portion 223 of the latch 22. As a result, the latch 22 rotates counterclockwise against the elastic force of a latch spring (not shown). During this time, the ratchet 23 has the end surface of the engaging portion 231 slidably contacted with the outer peripheral surface of the latch 22 by the elastic force of the ratchet spring (not shown), and the ratchet rotation shaft is appropriately selected according to the outer peripheral surface shape of the latch 22. It rotates around the 26 axis.

  When the door is further closed from the above-described state, the amount of the striker S entering the horizontal notch groove 211 gradually increases, so that the latch 22 pushed by the striker S further rotates counterclockwise. Eventually, as shown in FIG. 6, the engagement groove 221 of the latch 22 reaches the engagement portion 231 of the ratchet 23. In this state, since the latching portion 223 of the latch 22 comes into contact with the end surface of the engaging portion 231 of the ratchet 23, the latch 22 rotates clockwise against the elastic restoring force of a latch spring (not shown). Is prevented from rotating. In addition, since the hook portion 222 of the latch 22 is arranged so as to cross the horizontal cutout groove 211, the striker S moves in a direction away from the horizontal cutout groove 211 by the hook portion 222, that is, the door is opened with respect to the vehicle body. The operation is prevented (half latch state).

  Subsequently, when the door is further closed from the half-latch state, the striker S entering the horizontal cutout groove 211 further rotates the latch 22 counterclockwise via the locking portion 223. Eventually, as shown in FIG. 7, the striker S reaches the horizontal cutout groove 211. During this time, the ratchet 23 rotates clockwise against the elastic force of the ratchet spring (not shown) by the hook portion 222 of the latch 22 coming into contact with the upper surface of the engaging portion 231, and the hook portion of the latch 22. When 222 passes, it immediately turns counterclockwise by the elastic restoring force of a ratchet spring (not shown). As a result, as shown in FIG. 7, the hook portion 222 of the latch 22 comes into contact with the end surface of the engaging portion 231 of the ratchet 23, so that the latch 22 resists the elastic restoring force of a latch spring (not shown). Thus, the 22 clockwise rotation is prevented. Even in this state, the hook portion 222 of the latch 22 is disposed so as to cross the horizontal cutout groove 211, so that the striker S is moved by the hook portion 222 in a direction in which the striker S is disengaged from the back (outdoor) of the horizontal cutout groove 211. The situation is prevented, and eventually the door is kept closed with respect to the vehicle body (full latch state).

  Further, the action portion 232 of the ratchet 23 or the ratchet lever 27 is rotated clockwise about the axis of the ratchet rotation shaft 26 against the elastic force of the ratchet spring (not shown) from the above-described full latch state. Thereby, the contact engagement state between the hook portion 222 of the latch 22 and the engagement portion 231 of the ratchet 23 is released, and the latch 22 is rotated clockwise by an elastic restoring force of a latch spring (not shown). As a result, as shown in FIG. 5, the horizontal cutout groove 211 is opened, and the striker S can move in a direction away from the horizontal cutout groove 211, and the door can be opened with respect to the vehicle body. .

  1, the ratchet lever 27 is provided on the front side of the substrate 11 of the base plate 1 via the ratchet rotation shaft 26 so as to be rotatable about the ratchet rotation shaft 26 as an axis. A connecting end portion 271 connected to the portion 232, a working end portion 272 related to the release means, and a pressing end portion 273 extend in the radially outward direction of the ratchet rotation shaft 26.

  As shown in FIGS. 1 and 3, release means is provided on the front side of the substrate 11 of the base plate 1 (the front side of the vehicle body).

  The release means rotates the ratchet lever 27 described above in the clockwise direction in FIGS. 5 to 7 to release the full latch state or the half latch state of the latch mechanism so that the door can be opened with respect to the vehicle body. As shown in FIGS. 1 and 3, it has an open lever 31, a link lever 32, and an inside handle lever 33.

  As shown in FIG. 1, the open lever 31 is provided above the front side of the substrate 11 of the base plate 1. The open lever 31 is provided so as to be rotatable with respect to the substrate 11 via a latch rotation shaft 25. An open lever spring 34 is wound around the latch rotating shaft 25. The open lever spring 34 has one end engaged with the base plate 1 and the other end engaged with the open lever 31. Thereby, the open lever spring 34 always biases the open lever 31 clockwise in FIG.

  The open lever 31 is made of sheet metal and has one open action end 311 and the other open action end 312. One open action end 311 extends toward the left in FIG. The one open action end portion 311 is related to an opening operation of an outside handle (not shown) as a door handle disposed outside the door (outside the vehicle compartment). The other open action end 312 extends rightward in FIG. 1 and toward the side plate 12 of the base plate 1. The other open action end 312 is related to an opening operation of an inside handle (not shown) as a door handle disposed inside the door (vehicle interior side). The open lever 31 biased by the open lever spring 34 is in a state in which the other open action end 312 is in contact with a component fixed to the base plate 1 side (part of the latch body 21 in this embodiment). The rotation is restricted.

  The link lever 32 is made of a synthetic resin material, and extends in a longitudinal direction from the upper side to the lower side on the left side of the substrate 11 of the base plate 1 in FIG. The upper end portion of the link lever 32 is connected to one open action end portion 311 of the open lever 31. Specifically, a first connection shaft 321 is provided on the front surface (one surface) of the upper end portion of the link lever 32. The link lever 32 is connected to the one open action end 311 via the first connecting shaft 321 in a state where it is pivotally supported. As shown in FIG. 3, a second connecting shaft 322 is provided on the back surface (the other surface) of the upper end portion of the link lever 32. The link lever 32 is slidably engaged with the long hole 351 of the open rod 35 linked to the outside handle (not shown) via the second connecting shaft 322. Further, as shown in FIG. 1, an operating portion 323 extends laterally on the right side portion of the link lever 32. The operating portion 323 is related to the action end portion 272 and the pressing end portion 273 of the ratchet lever 27. An arc-shaped long hole 324 is provided at the lower end of the link lever 32. This long hole 324 is engaged with the lock mechanism side described later.

  The inside handle lever 33 is made of sheet metal, and is arranged so as to be rotatable around the axis of the lever rotation shaft 36 provided on the side plate 12 of the base plate 1 as shown in FIG. And a contact end portion 332. The linkage end 331 is a portion extending upward in FIG. 3 and is connected to an inside handle (not shown) via a cable (not shown). The abutting end portion 332 is a portion extending toward the other open action end portion 312 of the open lever 31 shown in FIG. 1, and when the inside handle lever 33 is rotated clockwise in FIG. This is for abutting the open action end portion 312 and turning the open lever 31 counterclockwise in FIG.

  When the latch mechanism is in the half latch state shown in FIG. 6 or the full latch state shown in FIG. 7, the outside handle is opened and the open rod 35 is pushed downward in FIG. When the inside handle is opened and the inside handle lever 33 rotates clockwise in FIG. 3, the open lever 31 resists against the elastic force of the open lever spring 34 as shown in FIG. Rotate clockwise. As described above, when the open lever 31 is rotated counterclockwise, the link lever 32 moves downward according to the rotation locus of the one open action end 311. The link lever 32 is translated in the downward direction in a state where the upper end portion thereof is pivotally supported by one open action end portion 311 by the first connecting shaft 321 and guided by the long hole 324 in the lower end portion. Along with this movement, the operating portion 323 of the link lever 32 abuts on the action end portion 272 of the ratchet lever 27 and rotates the ratchet lever 27 counterclockwise around the center of the ratchet rotation shaft 26. Then, the ratchet lever 27 and the ratchet 23 rotate integrally, and the contact engagement state between the hook portion 222 of the latch 22 of the latch mechanism and the engagement portion 231 of the ratchet 23 is released as shown in FIG. The door can be opened with respect to the vehicle body.

  When the outside handle is opened and the open rod 35 is pushed downward in FIG. 1, the open lever 31 rotates counterclockwise as shown in FIG. 8 (the open rod 35 in FIG. At this time, the other open action end 312 of the open lever 31 moves away from the contact end 332 of the inside handle lever 33. Therefore, a situation in which the opening operation of the outside handle affects the inside handle side is prevented. Further, when the inside handle is opened and the inside handle lever 33 is rotated clockwise in FIG. 3, the open lever 31 is rotated counterclockwise as shown in FIG. The rotation of the open lever 31 is not transmitted to the open rod 35 by the provided long hole 351. Therefore, the situation in which the opening operation of the inside handle affects the outside handle side is prevented.

  The lock mechanism makes it impossible to transmit the action of the release means described above to the ratchet lever 27 so that the full latch state of the latch mechanism can be locked (maintained). As shown in FIG. is doing.

  The lock lever 41 is made of a synthetic resin material and is provided below the substrate 11 of the base plate 1 as shown in FIG. The lock lever 41 has a lock lever rotation shaft 411, and the lock lever rotation shaft 411 is rotatably supported with respect to the substrate 11. The lock lever 41 has an approximately L shape, and one end thereof extends rightward in FIG. 1 and the other end extends substantially upward. An engagement hole 412 is provided at one end of the lock lever 41, and a lock operation lever 511 is inserted into and engaged with the engagement hole 412. The lock operating lever 511 is provided on the actuator 51 fixed to the side plate 12 of the base plate 1 as shown in FIG. 4, and is a lock operating portion (not shown) provided on the inner side (vehicle interior side) of the door. It is linked to. Further, as shown in FIG. 1, an engagement piece 413 is provided at the other end of the lock lever 41. The engagement piece 413 is inserted into and engaged with a long hole 324 provided in the link lever 32 of the release means. Although not shown in the drawing, when the lock lever 41 is rotated clockwise or counterclockwise around the lock lever rotation shaft 411 in FIG. 1, the rotated state is maintained by a spring. Be energized. In the present embodiment, a ratchet spring (not shown) that constantly biases the rotation direction of the ratchet 23 (and the ratchet lever 27) is used as the spring.

  The key lever 42 is made of a synthetic resin material, and is provided below the substrate 11 of the base plate 1 in a form superimposed on the lock lever 41 as shown in FIG. The key lever 42 has a key lever rotation shaft 421, and the key lever rotation shaft 421 is rotatably supported with respect to the lock lever 41. Note that the key lever rotation shaft 421 is disposed on the same axis as the lock lever rotation shaft 411. The key lever 42 is connected to one end extending to the left in FIG. 1 with a key rod (not shown) linked to a key cylinder (not shown) provided outside the door (outside the vehicle compartment). Further, in the key lever 42, as shown in FIG. 3, a key operation detection lever 512 provided in the actuator 51 is connected to an engagement piece 422 provided at the other end extending rightward in FIG. Further, the key cylinder (not shown) is configured such that the key hole into which the key is inserted is always in a predetermined direction (neutral position). In association with this, the key lever 42 is restricted to the predetermined rotation position shown in FIG.

  As shown in FIG. 1, the lock lever 41 is provided with a notch groove 414 around the axis of the lock lever rotation shaft 411. On the other hand, the key lever 42 is provided with a projecting piece 423 that engages with the notch groove 414. The engagement of the projecting piece 423 with the notch groove 414 has a predetermined play in the rotation direction of the levers 41 and 42.

  The lock mechanism configured as described above is operated when the door is closed with respect to the vehicle body and the latch mechanism is in the fully latched state as shown in FIG. When the lock lever 41 is rotated clockwise about the lock lever rotation shaft 411 as shown in FIG. 9 by the operation of the portion (not shown) or the actuator 51, according to the rotation locus of the engagement piece 413. The link lever 32 rotates. The link lever 32 is pivotally supported at one open action end 311 by the first connecting shaft 321 and the engagement piece 413 of the lock lever 41 is engaged with the long hole 324 at the lower end. As shown in FIG. 9, it rotates counterclockwise with the first connecting shaft 321 as an axis. When the link lever 32 rotates counterclockwise, the operating portion 323 of the link lever 32 moves to the right. In this state, when the release means is operated as described above, the link lever 32 moves in parallel as shown in FIG. 10, but the operating portion 323 does not come into contact with the action end portion 272 of the ratchet lever 27, and the latch 22. The contact engagement state between the hook portion 222 and the engagement portion 231 of the ratchet 23 is not released. As a result, the door is held closed with respect to the vehicle body, and the vehicle can be locked (locked state). Even when the key lever 42 is rotated clockwise about the key lever rotation shaft 421 in FIG. 1 by the key operation from the outside of the door (outside the vehicle compartment), the lock lever 41 is centered on the lock lever rotation shaft 411. Therefore, the locked state described above can be achieved.

  On the other hand, when the lock lever 41 is rotated counterclockwise about the lock lever rotation shaft 411 by the operation of the lock operation unit from the inside of the door (vehicle interior side) or the actuator 51 from the locked state described above. The link lever 32 rotates according to the rotation locus of the engagement piece 413. The link lever 32 is pivotally supported at one open action end 311 by the first connecting shaft 321 and the engagement piece 413 of the lock lever 41 is engaged with the long hole 324 at the lower end. As shown in FIG. 1, the first connecting shaft 321 is pivoted clockwise about the axis. When the link lever 32 rotates clockwise, the operating portion 323 of the link lever 32 moves to the left. In this state, when the release means is operated as described above, the operating portion 323 of the link lever 32 moved in parallel comes into contact with the operating end portion 272 of the ratchet lever 27 as shown in FIG. And the engagement portion 231 of the ratchet 23 are released, and the door can be opened with respect to the vehicle body (unlocked state). Even when the key lever 42 is rotated counterclockwise about the key lever rotation shaft 421 in FIG. 1 by the key operation from the outside of the door (outside the vehicle compartment), the lock lever 41 is interlocked with the lock lever rotation shaft. Since 411 rotates counterclockwise about the axis, the unlocked state described above can be achieved.

  By the way, in the door lock device in the present embodiment, the door is in an open state with respect to the vehicle body, and the lock 22 is locked by an operation of the lock operation unit in a state where the latch 22 is disposed at the open position as shown in FIG. The mechanism is locked (see FIG. 9). Here, the operating portion 323 of the link lever 32 moves rightward and faces the pressing end portion 273 of the ratchet lever 27. When the door is closed from this state, the latch 22 in contact with the striker S rotates clockwise toward the full latch state shown in FIG. For this reason, the ratchet 23 rotates counterclockwise in FIG. 9 with the end surface of the engaging portion 231 slidingly contacting the outer peripheral surface of the latch 22, and the ratchet lever 27 also rotates counterclockwise in the same manner. Then, since the pressing end portion 273 of the ratchet lever 27 pushes the operating portion 323 of the link lever 32 to the left, the link lever 32 rotates counterclockwise and the lock lever 41 rotates counterclockwise. Then, the lock mechanism returns to the unlocked state. In other words, even if the lock mechanism is locked by operating the lock operation unit with the key placed in the vehicle compartment, the lock mechanism returns to the unlocked state when the door is closed. Can be prevented (self-cancellation mechanism). On the other hand, when the door is open with respect to the vehicle body and the lock mechanism is locked by operating the lock operation unit (see FIG. 9), the release handle is operated by opening the outside handle or inside handle. Then, the link lever 32 moves in parallel as shown in FIG. 10, and the operating portion 323 is separated from the pressing end portion 273 of the ratchet lever 27. When the door is closed from this state, the pressing end portion 273 of the ratchet lever 27 does not contact the operating portion 323 of the link lever 32, so that the door can be closed while being locked ( Keyless mechanism).

  When the lock lever 41 rotates clockwise or counterclockwise about the lock lever rotation shaft 411, there is play in the engagement between the notch groove 414 of the lock lever 41 and the protruding piece 423 of the key lever 42. The key lever 42 does not rotate with the lock lever 41. As a result, when the lock lever 41 is rotated about the lock lever rotation shaft 411 by the operation of the lock operation unit from the inside of the door (vehicle interior side) or the actuator 51, the key cylinder (not shown) This prevents the keyhole orientation from changing.

  Hereinafter, assembly of the door lock device described above will be described. 11 is an exploded perspective view of the door lock device shown in FIG. 1 viewed from the front side, FIG. 12 is an exploded perspective view of the door lock device shown in FIG. 1 viewed from the back side, and FIG. 13 is a perspective view showing the base plate. 14 and 15 are perspective views showing the lock lever, FIG. 16 is a perspective view showing the key lever, FIGS. 17 and 18 are perspective views showing the link lever, FIG. 19 is a sectional view showing the assembly of the ratchet rotating shaft, and FIG.

  Here, a configuration of main parts related to the assembly of the door lock device will be described. As shown in FIG. 11, the latch rotation shaft 25 has a first step portion 252 that receives the thickness of the open lever 31 and rotatably supports the open lever 31 on the proximal end side having the retaining collar portion 251. Yes. The latch rotating shaft 25 receives the thickness of the base plate 1, the latch body 21, and the cover plate 24 stacked on the front end side of the first step portion 252, while the latch 22 is interposed between the latch body 21 and the cover plate 24. It has the 2nd step part 253 supported so that rotation is possible.

  As shown in FIG. 11, the ratchet rotation shaft 26 has a first step portion 262 that rotatably supports the ratchet lever 27 by receiving the thickness of the ratchet lever 27 on the proximal end side having the retaining collar portion 261.
