ABSTRACT:
An electric actuator including a stationary housing, an output shaft rotatably supported by the housing, an output member mounted on said output shaft, an electric motor secured to the housing, speed reduction gear mechanism for reducing the rotational speed of the electric motor, differential gear mechanism provided between the output shaft and the speed reduction gear mechanism, an electromagnetic brake operatively connected to the differential gear mechanism. The differential gear mechanism includes an output side differential gear secured to the output shaft, and a brake side differential gear rotatable with a brake plate of the electromagnetic clutch. The electromagnetic brake includes an electromagnetic coil and an electromagnetic yoke secured to the housing, so that when the brake side differential gear is prevented from rotating by the electromagnetic brake the electric motor controls displacement of the output member, and when the brake side differential gear is freely rotatable relative to the housing the output member is freely rotatable irrespective of the rotation of the electric motor.
