Abstract
A lens driving device including: a lens barrel having at least one lens therein and provided with a friction member; a housing for housing the lens barrel therein; an actuator having a piezoelectric body disposed at an edge of the housing to apply a driving force, the piezoelectric body having at least one output member provided at one side thereof to be in contact with the friction member; a preload member disposed between the edge of the housing and the actuator to apply an elastic force toward the lens barrel; and a guiding part disposed between the housing and the lens barrel to guide the lens barrel to move in an optical axis direction. The lens driving device is simplified in a driving mechanism and thus reduced in size, while experiencing minimum loss of a driving power and ensuring more accurate and stable movement of the lens.
