<p>Provided is a vibration wave motor including: a vibration member (100) having an elastic body (102) joined with a electric -mechanical energy converter (105); and a moving member (101) contacting the vibration member, the vibration member and the moving member being annularly formed, the vibration wave motor frictionally driving the moving member by a motion generated at a contacting portion with the moving member of the vibration member upon application of an AC signal to the electric -mechanical energy converter. The vibration wave motor includes a centrifugal fan (200) provided at an outer peripheral portion and/or an inner peripheral portion of a circular ring formed of the vibration member and the moving member, and the centrifugal fan rotates integrally with the moving member.</p> |
