Claims

[Scope of utility model registration request]

a casing; an annular ultrasonic vibrator disposed within the casing that generates vibrations by applying a high frequency voltage from the outside; one surface fixed to the ultrasonic vibrator and disposed within the casing; an annular elastic body that generates a surface wave on the other side surface; A surface wave motor includes a rotor that is rotationally driven by a rotor, and an output shaft that outputs the rotation of the rotor to the outside.The rotor is provided with internal teeth, the output shaft is provided with external teeth, and the A surface wave motor characterized in that an intermediate gear rotatably supported by the casing is interposed between the external teeth and the internal teeth.
