Abstract
A lock shaft and a shaft member (a plunger and a permanent magnet) of a magnetic locking device are arranged such that a moving direction thereof is orthogonal to a moving direction of a piston rod of a hydraulic actuator. In a parking lock released state, when the coil is not energized, the lock shaft and the shaft member are locked by an attracting force between the permanent magnet and a flange of a yoke so as not to move back from the piston rod, and, when the coil is energized, the attracting force between the permanent magnet and the flange is canceled, so that the lock shaft and the shaft member are allowed to move back from the piston rod.
