A vibration actuator capable of vibrating plural rotors by single vibration means. Two rotors (A, B) are pulled by tension of a wire member (8) and pressed and made to be in contact with corresponding stators (3, 4), individually. A composite vibration formed by composing different vibrations is generated by a composite vibrator (2) to form elliptic motion at a corner of each of the stators (3, 4). By this, the two rotors (A, B) pressed and made to be in contact with the two stators (3, 4) are simultaneously rotated about respective rotation centers (C1, C2).
