Abstract:
A vibration wave driving apparatus can match the vibration direction of a projecting portion of a vibrator to the displacement direction of a contacting portion of a driven body so that the projecting portion of the vibrator and the contacting portion of the driven body can be brought into contact and driven with stability. The vibration direction of the projecting portion is affected by selecting the position of the projecting portion relative to the nodes of vibration.
