摘要： It is an object to provide a small ultrasonic actuator whose voltage control is easy. The ultrasonic actuator acts on a rotatable rotor to rotate the rotor, the ultrasonic actuator includes: a plate vibrator having one end which contacts the rotor, a corner portion bent at a midpoint in the vibrator, and the other end which is fixed; and a piezoelectric device which contacts a part of the vibrator between the one end and the corner portion, and transmits a vibration to the vibrator by vibrating in response to application of an alternating voltage between one of electrodes provided respectively on both surfaces or the plate vibrator serving as the one of the electrodes and the other of the electrodes.
