OSCILLATORY WAVE DRIVE UNIT AND IMAGE STABILIZATION DEVICE

摘要

An oscillatory wave drive unit includes at least one vibrator having an electromechanical energy converting element, and at least one supporting member configured to support the at least one vibrator. The oscillatory wave drive unit excites oscillation in the at least one vibrator and moves a moving body in contact with the at least one vibrator by frictional force. The oscillatory wave drive unit includes at least one moving mechanism configured to support the at least one vibrator movably in a plane parallel to the plane where the at least one vibrator and the moving body are in contact with each other, in a second direction intersecting with a first direction in which the at least one vibrator drives the moving body.
