ABSTRACT:
A miniaturized ultrasonic motor comprises a stator having an elastic body on which a travelling oscillatory wave is generated and which is supported on a fixing unit in a manner that prevents rotation of the elastic body but permits axial movement of the elastic body. The travelling oscillatory wave rotates a rotor that contacts protruding portions of the elastic body, and the rotor rotates a driven body therewith. The driven body engages the rotor in a manner that constrains the driven body to rotate with the rotor but that permits relative axial movement of the driven body and the rotor body.
