Abstract
A hydraulic unit and an electromagnetic unit are disposed in directions that are orthogonal to each other. The electromagnetic unit is configured such that a solenoid shaft is held when a coil is energized, and such that movement of the solenoid shaft toward the right side in the drawing is allowed during movement of the piston rod when the coil is not energized. When a hydraulic pressure for a piston is reduced with the coil not energized in a parking unlocked state, switching is performed to a parking locked state with a piston rod moved downward in the drawing while moving the solenoid shaft rightward in the drawing through abutment between a roller of a pin of the piston rod and a distal end portion of the solenoid shaft.
