In such a shift lock device 21, the key lock cam 22 is restricted by the P lock cam 29, and the P lock cam 29 can be attached with the key lock cam 22 as a reference. Further, the P lock cam 29 is attached together with the key lock cam 22 to one member, that is, the detent plate 4.

Therefore, the shift lock device 21 can be easily and highly accurately installed in the vehicle without providing a mark or the like for mounting or visually observing the mounting position of each member. In addition, the key lock cam 22 of the lock pin 32
Since it is possible for the installation operator to visually check the positional relationship with respect to, the connection state of the shift lock cable 34, and the like, an adjustment error and an adjustment variation are less likely to occur.

Further, since the key lock cam 22 and the P lock cam 29 are offset from each other and are attached in a state in which the two members 22 and 29 are not in contact with each other, for example, the brake pedal is released from the pedaling force and P
When the lock cam 29 returns, it can be prevented from coming into contact with the key lock cam 22 and generating an interference sound.

Further, in this embodiment, the locking projection of the key lock cam 22 is
Since the upper corners of 26 are gently curved,
When the bush button of the lever 12 is operated to release the shift lock, the P-lock cam 29 can be rotationally displaced and the lock pin 32 can be smoothly disengaged from the locking convex portion 26, and a feeling of catching can be obtained. It does not occur, and the operability can be improved.

Further, since the long hole 37 is formed in the cable end 36 of the shift lock cable 34, the long hole 37 can absorb the displacement of the P lock cam 29 when the detent pin 13 slides, for example, and the shift lock cable 34 can be absorbed. It is possible to prevent unreasonable force such as pulling force from being applied to.

Further, in the shift lock device 21, the key lock cam 22 is provided with a passage 27 formed between the sleeve 24 and the locking projection 26. For this reason, for example, when the shift lock cable is cut, that is, when a so-called cord break occurs, the lock pin 32 of the P lock cam 29 released from the tension of the inner cable 35 is caused to enter the passage 27.

Then, the shift lock device 21 releases the key lock cam 22 from the lock pin 32, and allows the key lock cam 22 to be displaced many times regardless of the lock pin 32. Therefore, even if the shift lock device 21 is broken, the select lever 12
Does not interfere with the selection operation of.

Further, since the shift lock device 21 has the set lever 38, when the shift lock cable 34 is attached, the P lock cam 29 and the shift lock cable pin 33 are provided.
Can be positioned using the set lever 38. Then, the P lock cam 29 can be positioned at the distance a between the center of rotation of the set lever 38 and the lock pin notch 39. Therefore, the shift lock cable 34 can be attached without slack, and variations in adjustment can be reduced.

Here, when the shift lock cable 34 is attached, the outer cable 34a may be lightly pulled to the brake pedal side, that is, to the side indicated by the arrow C in FIG.

Also, since the set lever 38 can be fixed to the key lock cable pin 33, the shift lock cable
Even after the installation of 34 is completed, the set lever 38 is locked by the P lock cam.
It does not disturb the movement of 29. After the shift lock cable 34 has been attached, the set lever 38 can be used as a washer for attaching the key lock cable 16.

Even after the shift lock device 21 is installed, the set lever
Since the 38 can be assembled and stored in the shift lock device 21, for example, when the shift lock device 21 is reassembled at a later date, the shift lock device 21 can be easily reset by using the set lever 38. be able to.

The present invention is not limited to the type of vehicle in which the select lever 12 is provided on the floor portion of the vehicle body, and is applicable to, for example, a vehicle of the type in which the select lever 12 is provided in the steering column portion.
