Claims

[Claims for Utility Model Registration] (1) An annular ultrasonic vibrator that generates vibrations by applying a high-frequency voltage from the outside via wiring; An annular elastic body that resonates with the vibration of the child and generates a surface wave on the other surface, and a spring material that is pressed against the other surface of the elastic body with a constant load. a rotor driven by body surface waves; an output shaft protruding from the center of the rotor in the axial direction; A surface wave motor consists of a bearing attached to the main body casing to apply a constant load to the motor. (2) The surface wave motor according to claim (1), wherein the wiring is passed between the rotor and the main body casing and taken out in the axial direction of the main body casing. (3) The scope of the utility model registration claim, in which the rotor is provided with a circumferential elongated hole, and the wiring is taken out in the axial direction of the main body casing through the elongated hole.
The surface wave motor described in (1).
