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 comprising a gap adjustment member capable of changing the gap between a portion of the mirror holder and a portion of the holder support part, provides superior vibration characteristics, as the viscous fluid is not heated by the driving part.
