<p>PROBLEM TO BE SOLVED: To provide a pressing mechanism for a standing wave type piezoelectric vibration motor which can press a vibrator to a driver side in a stable state by reducing the disturbance of vibration of the vibrator, and a lens driving device using a standing wave type piezoelectric vibration motor having the pressing mechanism.SOLUTION: A pressing mechanism for a standing wave type piezoelectric vibration motor is provided on the one end side of a piezoelectric vibration motor body, and brings a vibration output terminal on the other end side into contact with a driven object with energization. The pressing mechanism uses an energizing member provided with a contact surface which comes into contact with the surface on the one end side of the piezoelectric vibration motor body to press it, and has lubricant slide resistance reduction means which makes the contact surface of the energizing member retain a lubricating agent in order to reduce slide resistance generated between the vibrating piezoelectric vibration motor body and the energizing member.</p> |
