PURPOSE:To improve the mass productivity of a vibration wave motor by using a circular vibration absorber also as a power supply member and reducing the outer diameter of the absorber smaller than that of a circular vibrator to enhance the driving efficiency. CONSTITUTION:A vibration absorber 13 is formed of a rubber, a felt, etc., to prevent a mechanical vibration from being transmitted to a stationary cylinder. The absorber 13 is disposed not on the entire bottom of a vibrator 15 or an electrostrictive element 14 but at the inside of the ring-shaped bottom as a center. The vibrator 13 is composed separately of ring-shaped conductive felts 13a-13d and nonconductive felt to operate as a power supply element to the electrode of the element 14. |
