Abstract
An electric actuator includes an outer cylinder, a sliding unit and a screw shaft. At least one guiding groove is provided in a hole wall of the outer cylinder. The sliding unit includes a nut member, a rotation-restricting member engaged on a first end of the nut member, and an output shaft engaged on a second end of the nut member. The rotation-restricting member has at least one guiding block movably combined in the guiding groove of the outer cylinder. The screw shaft is connected with the nut member in a relatively movable manner. When the screw shaft rotates, the nut member, the rotation-restricting member and the output shaft move with respect to the screw shaft, and the guiding block of the rotation-restricting member moves inside the guiding groove, so as to restrict the nut member and the output shaft from rotating relative to the outer cylinder.
