Abstract: In a shift lever device, a lock bar is disposed in a restricting position to restrict changing of a shift position of a lever. A motor is driven to rotate a cam in order to move the lock bar to a non-restricting position, thereby permitting changing of the shift position of the lever. The lock bar is moved as the rotation position of the cam is changed. This enables the precision required of the rotation position of the cam in order to dispose the lock bar in the restricting position and the non-restricting position to be lowered, thereby enabling appropriate switching between restriction and permission of changes in shift position of the lever to be performed by driving of the motor.
