Abstract
An ultrasonic actuator includes an actuator body; and driver elements for outputting drive force, which are provided to the actuator body. The ultrasonic actuator further includes a holder which is provided to the actuator body, and which protrudes outwardly beyond principal surfaces in a direction crossing the principal surfaces of the actuator body; two supports for supporting the holder; contact rubber blocks limiting displacement of the actuator body by contacting the principal surfaces of the actuator body. The actuator body is biased toward a movable body side. A long hole extending in a biasing direction of the actuator body and into which the holder is fitted is formed in the support. At least two contact rubber blocks contact the principal surfaces of the actuator body at different positions in a longitudinal direction of the actuator body.
