Abstract
An optical unit with a shake correcting function may include a fixed body, a movable body holding an optical element, a swing support point supporting the movable body at a position between a rear end portion of the movable body and the fixed body so that the movable body is swingable, a plate-shaped spring member connected with the fixed body and the movable body on a front side for urging the movable body toward the swing support point, a shake correction drive mechanism for swinging the movable body on the front side, and a stopper mechanism in which a protruded part protruded from one of the fixed body and the movable body is capable of abutting with the other between the shake correction drive mechanism and the swing support point for determining a movable range when the movable body is displaced in a direction perpendicular to the optical axis direction.
