Abstract
A parking mechanism includes a shaft, a movable portion rotatable with the shaft, a pawl having a claw and movable as the movable portion rotates, a parking gear meshable with the claw, and a stopper contactable with the movable portion. The pawl is switched between parking and non-parking positions in which the claw meshes with and separates from the parking gear, respectively. The movable portion has a first elastic member attached to the shaft, and a contact member connected to the shaft via the first elastic member and in contact with the pawl. The contact member is rotatable in a rotational direction relative to the shaft as the first elastic member is elastically deformed, and is contactable with the stopper in the rotational direction. The stopper faces the contact member at a distance in the rotational direction when the pawl is switched between the parking and non-parking positions.
