- the rotation axis of the pole 32 (pole bush 31) and the rotation axis of the cam member 36 (cam pin 35) are different from each other. Thereby, a difference is made between the distance from the rotation axis of the pole 32 to the pole protrusion 33 and the distance from the rotation axis of the cam member 36 to the pole protrusion 33. Therefore, the engagement / disengagement timing of the pole 32 and the cam member 36 can be arbitrarily adjusted by the difference in the distance.
- the rotation with the pressing of the latch 27 by the cam member 36 is possible until the end of the locking surface 36b reaches the latch locking projection 30 (maximum driving state). It is. In other words, even if the rotation position of the latch 27 where the striker 20 abuts against the bottom surfaces 241a and 251a of the base grooves 24a and 25a is changed due to variation in assembly or aging, as long as the cam member 36 is within the above-described rotation range.

- the cam member 36 in which the pole protrusion 33 of the pole 32 is fitted into the cam groove 37 rotates in the clockwise direction in conjunction with the rotation of the pole 32. That is, the cam member 36 is within the range shown in FIGS. 5 (b) to 5 (c) in which the pawl 32 is pivoted from the unlocked position to the pivot position (full stroke) that is substantially maximum in the clockwise direction.
- the protrusion 33 is held by the pole 32 by fitting into the cam groove 37.
- the cam member 36 is set so that at least a part of the cam member 36 always overlaps the latch 27 in the axial direction regardless of the rotational position of the latch 27.
- the positioning portion 36c is rotated to the rotation position (full stroke) where the pole 32 is substantially maximum in the clockwise direction, and the cam member 36 is approximately maximum from the latch 27. Even if they are separated, they are formed so as to overlap the latch 27 in the axial direction. Accordingly, the cam member 36 is prevented from being displaced in the axial direction with respect to the latch 27 when the latch 27 is rotated.

- the pole 32 is urged by the pole spring 42 so that the first pole engagement surface 32d becomes the second latch engagement surface 29b. It rotates in the counterclockwise direction until it comes into contact with and returns to the allowable position.
- the operation lever 22 connected to the pole 32 via the snap 34 is disposed at different positions corresponding to the allowable position and the locking position of the pole 32.
- the rotation range of the pole 32 can be set suitably without being restricted by the rotation range of the cam member 36.

Therefore, it is possible to avoid an increase in assembling error due to an increase in the number of parts, thereby reducing the assembling man-hours.
- the operation levers 22 are arranged at different positions corresponding to the allowable position and the locking position of the pole 32. For this reason, by visually confirming the position of the operation lever 22, the position of the pole 32, that is, the restrained state or the released state of the striker 20 by the latch 27 can be confirmed, and the operability can be improved. For example, the striker 20 can be prevented from being left in an incompletely restrained state.
- a part of the cam member 36 overlaps the latch 27 in the axial direction in the entire range in which the latch 27 can rotate. Therefore, for example, when the latch 27 rotates, the cam member 36 can be prevented from being displaced in the axial direction with respect to the latch 27 and becoming inoperable.

- the latch 27 can be prevented from rotating in the direction toward the unlock position.
- the radial distance from the rotation axis (pole bush 31) of the pole 32 to the step 32c is set shorter than the radial distance from the rotation axis (cam pin 35) of the cam member 36 to the locking surface 36b. Therefore, the strength of the pole 32 against the external force can be sufficiently secured.
- the latch engagement surface 30a may have a planar shape that is substantially orthogonal to the radial direction centered on the boss 25d at the lock position of the latch 27.
- the cam member 36 may be formed with a protruding portion that protrudes in the thickness direction, and a locking surface that locks the protruding portion may be formed on an appropriate end surface of the latch 27.

- the radial distance from the rotation axis (pole bush 31) of the pole 32 to the step 32c is set shorter than the radial distance from the rotation axis (latch bush 26) of the latch 27 to the locking surface.
- the cam groove 37 as the engaging recess may be a cam hole into which the pole protrusion 33 is inserted with play, or may be a cam hole with which the pole protrusion 33 is engaged.
