れたばねとから構成してなる表面波モータ。 An ultrasonic transducer is formed in an annular shape and is inclined at a predetermined angle along the central axis, and generates vibration by applying a high frequency voltage from the outside. an annular elastic body that is bonded to the ultrasonic transducer and resonates with the vibrations of the ultrasonic transducer and generates a surface wave on the other surface; a rotor, the outer peripheral portion being pressed against the other surface of the elastic body with a constant load and driven by the surface waves of the elastic body; and a rotor having a constant load applied to the rotor. A surface wave motor comprising a spring disposed via a bearing on the inner circumferential portion of the rotor in order to provide a surface wave motor.
