VIBRATORY ACTUATOR DEVICE AND LENS BARREL

摘要

PROBLEM TO BE SOLVED: To provide a vibratory actuator device and a lens barrel which allow the size of the incorporated portion of a pressurizing mechanism to be reduced. SOLUTION: The vibratory actuator device is provided with an ultrasonic actuator 1 and a pressurizing mechanism which brings the ultrasonic actuator 1 into contact with a driven body 3 under pressure. The pressurizing mechanism is provided with a pressurizing spring 7 which produces energizing force, and a lever 8 which transmits energizing force produced by the pressurizing spring 7 to an ultrasonic actuator 2. The lever 8 converts energizing force produced by the pressurizing spring 7 almost in the perpendicular direction.
