Abstract

In a shift device, as a result of a rotor cam being rotated in a positive direction, and transmitting surfaces of the rotor cam pressing rotation surfaces of an urging cylinder, the urging cylinder is rotated in the positive direction, and a lever is moved rotationally towards a front side. Here, in a case in which a load towards the rear side is applied to the lever, the rotation surfaces are rotated in an opposite direction relative to the transmitting surfaces. As a result, the load towards the rear side being applied to the lever can be released.

First claim

What is claimed is:

1. A shift device comprising:
a shift body in which a shift position is altered as a result of the shift body being moved;
a movement mechanism that transmits motive force to the shift body so that the shift body is automatically moved; and
a release mechanism that is provided on a motive force transmission path from the movement mechanism to the shift body, and that, in a case in which movement of the shift body to which motive force is to be transmitted by the movement mechanism is restricted, releases a movement restricting force applied to the shift body.

2. The shift device according to claim 1 , further comprising an urging mechanism that urges the shift body towards a shift position side, and urging of the shift body by the urging mechanism is restricted in a case in which the movement mechanism transmits motive force to the shift body.

3. The shift device according to claim 2 , wherein the release mechanism restricts urging of the shift body by the urging mechanism in a case in which the movement mechanism transmits motive force to the shift body.

4. The shift device according to claim 2 , wherein, in a case in which the movement mechanism transmits motive force to the shift body, the urging mechanism is maintained in a state in which urging of the shift body by the urging mechanism is restricted.

5. The shift device according to claim 2 , wherein, after the movement mechanism has ended transmission of motive force to the shift body, the urging mechanism urges the shift body towards the shift position side.

6. The shift device according to claim 1 , wherein, after movement of the shift body to which the movement mechanism is transmitting motive force has been restricted, the movement mechanism is restored to a state the movement mechanism was in prior to transmitting motive force to the shift body.

7. The shift device according to claim 1 , wherein the release mechanism releases the movement restricting force being applied to the shift body while resisting urging force.

8. The shift device according to claim 7 , further comprising an urging mechanism that urges the shift body towards a shift position side, and the release mechanism releasing the movement restricting force being applied to the shift body while resisting the urging force of the urging mechanism.

9. The shift device according to claim 1 , wherein the release mechanism releases the movement restricting force applied to the shift body when the movement restricting force reaches a predetermined threshold.

10. The shift device according to claim 1 , wherein the movement mechanism includes a drive train, and the release mechanism forms part of the drive train of the movement mechanism.
