Abstract
An oscillatory wave motor includes an oscillator having an oscillation body and an electro-mechanical energy-converting element, and a flexible heat-conducting member configured to dissipate heat generated by the oscillatory wave motor. The oscillatory wave motor drives a moving body in contact with a contact portion formed in the oscillation body by an elliptical movement of the oscillator, and the heat-conducting member is provided in addition to a heat-conducting path that conducts heat generated by the oscillatory wave motor through an oscillator supporting member that supports the oscillator or a heat-conducting path that conducts heat through the moving body.
