PURPOSE: To enable downsizing and get smooth rotation without oscillation by forming a transmission means such as a gear, a pulley, a cam, etc., at a rotor receiver fixed to a rotor shaft, and arranging a vibration insulating material between a rotor and the rotor receiver. CONSTITUTION: A stator unit 1 is composed of an oscillator 2, a piezoelectric element 3, a flexible board 4, and a frictional material 5, and a rotor unit 8 is composed of a shaft 9, a rotor receiver 10, a vibration insulating material 12, a rotor 13, a spring 14, and a spring receiver 15, and the rotor 13 in contact with the stator unit 1 is retained with the rotor receiver 10 through the vibration insulating member 12. And, a gear 11 is made around the rotor 10 fixed to the shaft 9, and it transmits force from the gear 11 to other gear 23, and the output is obtained from the shaft 22. Hereby, a rotating object being large transmission mechanism and a drive source can be housed in a small space, adding functions such as gear 11, or a pulley, a cam, etc., to the rotor receiver 10 being a part large in diameter, and also the vibration insulating material 12 can stabilize the rotation property. |
