Abstract

When a lock bar is moved in a state in which a cam is rotated and an abutting face is abutted on a cam face of the cam, the abutting face is abutted on a circumferential face of the cam at a location excluding a lock bar moving direction position with respect to a center of rotation. Accordingly, a movement stroke of the lock bar with respect to a rotation angle of the cam can be increased.

First claim

What is claimed is:

1. A shift device comprising:
a rotation body that is rotatable to change a shift position;
a movement member that is configured to be moved to one side in a moving direction of the movement member to restrict rotation of the rotation body, and to be moved to another side in the moving direction to release restriction of rotation of the rotation body, the moving direction being a direction perpendicular to an axis of rotation of the rotation body; and
a cam member that is rotatable about an axis different from the axis of rotation of the rotation body, that is provided with a cam face, and that is configured to be rotated in one direction or another direction, such that the movement member is moved toward the one side or the another side in a state in which the movement member is abutted on the cam face at a location that excludes a position at which a line extending from a center of rotation of the cam member in the moving direction of the movement member intersects with the cam face,
wherein, in a state in which the movement member is abutted on the cam face at a location including a position at which a line extending from the center of rotation of the cam member in a direction perpendicular to the moving direction intersects with the cam face, the cam member is configured to be rotated in the one direction or the another direction such that the movement member is moved toward the one side or the another side.

2. The shift device of claim 1 , wherein an abutting face of the movement member, which is abutted on the cam face, is inclined with respect to the moving direction of the movement member and with respect to a direction perpendicular to the moving direction of the movement member.

3. The shift device of claim 2 , wherein the abutting face is inclined in a direction so as to being away from a center of rotation of the cam member in the direction perpendicular to the moving direction of the movement member on progress toward a side of the rotation body in the moving direction of the movement member.
