ABSTRACT:
Disclosed is an electric actuator which makes it possible to prevent a driving force-transmitting shaft from adhesion of dust or the like, and eliminate any fear for deterioration of driving force-transmitting function. A hole is defined in a body which is arranged to extend in a vertical direction. A motor is secured to one end of the body. A feed screw is coaxially connected to a rotary shaft of the motor. The feed screw is rotatably supported by angular contact ball bearings. A feed nut is engaged with the feed screw. The hole is slidably engaged with a cylinder member which is formed to be cylindrical and lengthy. The cylinder member surrounds the feed screw. The feed nut is secured to one end of the cylinder member, and a bracket is secured to the other end thereof.
