Title: ELECTRICAL ACTUATOR
Abstract:
This electrical actuator is provided with a motor unit A and a motion conversion mechanism unit B, the motion conversion mechanism unit B having a screw shaft 33 that is disposed coaxially with the rotational center of a rotor 24 of the motor unit A, a nut member 32 that is rotatably fitted therearound, and a planetary gear decelerator 10 that decelerates and outputs the rotation of the rotor 24, the screw shaft 33 advancing in one axial direction or retreating in another axial direction in accordance with the direction of rotation of the nut member 32, wherein: the nut member 32 is disposed within the inner periphery of the rotor 24, and linked, in a manner that allows for the transmission of torque, to a planetary gear carrier 43 serving as an output member for the planetary gear decelerator 10.
