Oscillation motor and lens driving mechanism
Abstract:
An oscillation motor is adapted to press an oscillator toward a driven body in a stable state and increasing a drive efficiency. A lens driving mechanism is adapted to move a lens with excellent efficiency by using the oscillation motor. An oscillation motor generates motive power by pressure contact with a driven body to transmit vibration of the oscillator to the driven body. The oscillation motor includes the oscillator having a convex output portion on a side surface at one end side. The output portion of the oscillator is arranged to contact with the driven body. A press mechanism is also provided on a side surface at the other end side of the oscillator. The press mechanism includes a pressure correction device rotatably equipped at a position where the pressure correction device contacts with the oscillator, and the pressure correction device applies a pressure to the oscillator in a predetermined direction.
