Vibration Actuator

Abstract

Provided is a vibration actuator in which a plurality of rotors can be driven by a single vibration unit. Two rotors (A) and (B) are attracted toward corresponding stators to be contacted with and pressurized against the corresponding stators (3) and (4), respectively, through a tension of a wire member (8). A composite vibration combining a plurality of vibrations is generated by a composite vibrator (2) to cause elliptical movements in corner portions of the stators (3) and (4). As a result, the two rotors (A) and (B) abutting onto and pressurized against the two stators (3) and (4) are rotated about rotation centers (C1) and (C2) thereof, respectively, at the same time.

Dependencies are inferred from the claim text.
