摘要： A motor includes a rotatable cylindrical rotor housed in a stator and has a female threaded nut formed inside the rotor. The motor has a male threaded screw shaft engaging with the nut. The rotation of the rotor is transformed to linear movement of the screw shaft by restricting the rotation of the screw shaft. A plurality of engaging sections project from the screw shaft. A contact section is provided with the rotor to contact with the engaging sections. The contact section contacts the engaging sections in accordance with the rotation of the rotor to restrict the rotation of the rotor and to prevent the screw shaft from releasing from the rotor.
