PROBLEM TO BE SOLVED: To make a vibration wave motor more compact without lowering output nor driving efficiency.SOLUTION: A vibration wave motor according to the present invention has a vibrator which vibrates with an applied high-frequency voltage; a vibrator fixed member to which the vibrator is fixed; pressing means of pressing a slide part formed at the vibrator; a slide member against which the slide member is pressed by the pressing means; a vibrator support member which holds the vibrator and is driven relatively to the slide member; and a coupling member which couples the vibrator fixed member and vibrator support member together, the vibrator support member and coupling member being fastened at least in a part of a projection region formed by projecting the vibrator fixed member on a plane having its normal in a pressing direction of the pressing means.SELECTED DRAWING: Figure 1 |
