Provided is a vibration wave motor including: a vibration member having an elastic body joined with a electric-mechanical energy converter; and a moving member 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 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. |
