Title: Oscillation motor unit, oscillation motor, and lens driving device using oscillation motor

Abstract: The object of the present invention is to provide a driving mechanism which is a higher powered motor that can be used even when an installation space is limited by reducing a space required for installation of the motor as a motive power of a driving mechanism, and which prevents the influences of vibration and heat generation in the operation. To achieve the object, an oscillation motor unit, an oscillation motor and a lens driving device are employed in which the vibrator, a push mechanism pushing the vibrator in a specific direction to transmit the motive power of the vibrator in which a vibrator is made vibrate and convert the vibration energy to a motive power transmitted are included, wherein a first base member for setting the vibrator and the push mechanism is set at the position where the first base member is sandwiched between the vibrator and the push mechanism.
