PURPOSE:To raise the rotating speed and torque in a simple constitution and decrease the rotating nonuniformity by fitting an elastic vibrating piece on both sides of vibrating direction of the piezoelectric vibrator and by pressurizing and contacting a driven unit, thereto respectively. CONSTITUTION:On both sides of a piezoelectric vibrator 14 annular elastic vibrating pieces 13 and 15 are provided respectively, on the outside of which each sliding disc 11 and 17 is pressurized and contacted through friction plates 12 and 16. Vibrations given to the piezoelectric vibrator 14 is transferred to elastic vibrating pieces 13 and 15 on both sides, by which each sliding disc 11 and 17 on both ends of a motor can be driven. |
