Abstract

A lens driving device includes a lens frame for holding a photographic lens; a guide member for guiding the lens frame in a direction of an optical axis of the lens; a lead screw for moving the lens frame in the optical axis direction; a drive source for rotating the lead screw; and a carriage for being in pressure contact with the lead screw and thereby for converting a rotational motion of the lead screw caused by the drive source to a linear motion in a direction parallel to the optical axis direction which is a moving direction of the guide member. When pressure contact points between the carriage and the lead screw are projected onto a plane perpendicular to a rotational axis of the lead screw, a projected image includes at least three pressure contact points.
