Abstract
A vibration type tilting device, according to an embodiment of the invention, which comprises a mirror holder, supporting a mirror on one side, which tilts together with the mirror such that the mirror periodically tilts light on a light path in a minute angle; a holder support part supporting the mirror holder; a driving part, which supplies driving power to the mirror holder; and a damping part positioned between the mirror holder and the holder support part to reduce overshoot of the mirror holder, can improve the vibration performance of the tilting device to provide a smoother and clearer picture quality.
