Abstract
A locking mechanism capable of locking and unlocking the rotation of the rotor shaft of an electric motor is constituted by a plurality of recesses formed in one side surface of one gear of a plurality of gears of a reduction gear mechanism. A locking pin is movable toward and away from the recesses, and is configured such that when the locking pin moves toward the recesses, the locking pin engages in one of the recesses and locks the one gear. A linear solenoid is configured to move the locking pin toward and away from the recesses, and a protrusion extends from one end surface of each recess.
