Abstract
An actuator apparatus includes an oil passage body including an oil passage therein, an electric actuator, a movable unit moved at least in a first direction and a second direction by the electric actuator, and an auxiliary device including an actuating member moved by hydraulic pressure of oil in the oil passage. When the electric actuator moves the movable unit in the second direction, the auxiliary device applies, through the actuating member to the movable unit, a force pointing in a direction that moves the movable unit in the second direction.
