Abstract
A lens driving device including: a lens holder; a coil mounted on the lens holder; at least one magnet disposed around the coil; a first and second spring members which support the lens holder at the both sides thereof in the optical axis direction so that the lens holder can move freely in the both directions of the optical axis of the lens in an initial state of no electric current to the coil; and an abutment surface to which the lens holder abuts when the lens holder moves toward one spring member against a biasing force of the one spring member; wherein the lens holder is exhorted a biasing force by the other spring member from the side of the other spring member to the side of the one spring member in the optical axis direction when the lens holder abuts against the abutment surface. Thus the lens driving device can support a lens holder in a stable fashion.
