Abstract: A rotary actuator is used in a shift-by-wire system for a vehicle. A speed reducer includes a ring gear and a sun gear and reduces a rotational speed of the motor. An output shaft outputs rotation of the motor at a reduced rotational speed by the speed reducer. A regulating pin is disposed in a fixing member and allows the sun gear to revolve around a rotational axis of the motor and to rotate about an eccentric axis. The regulating pin is a separate member from the fixing member. The regulating pin has a strength equal to or greater than a maximum torque reaction force received from the sun gear. A first difference in hardness between an engaging portion and the sun gear is set to be less than a second difference in hardness between the fixing member and the sun gear.
