Abstract
An ultrasonic motor achieves uniform contact between a vibrating body and a moving body and features high output transfer efficiency and high reliability. The manufacturing process for the moving body can be simplified and the moving body made lighter by making the moving body of a carbon fiber reinforced resin composite material reinforced by at least carbon fiber, and constructing the moving body with a both-side supported or single-side supported beam construction. Elasticity according to the pressure of the ultrasonic motor can be imparted in the direction of pressure of the moving body. Thus, the undulations in the contact surface of the vibrating body and the moving body can be absorbed, stable, uniform contact can be assured, and long-term maintenance of a stable friction condition can be achieved.
