PURPOSE: An electromotive cylinder is provided to improve productivity of a product by simplifying a structure. CONSTITUTION: A guide hole(110) is formed in the inner side of a body frame(100). One or more air paths are formed in around the guide hole. A reversible electric motor(200) is combined to the rear side of the body frame and generates power. A screw shaft(300) is axis-connected to the reversible electric motor and reversely revolves in the inner side of the body frame. A main shaft(400) forms a flange(420) moving front and back in the inner aide of the guide hole. A guide bush(500) is combined to the flange while surrounding the external rear side of the main shaft.
