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 which supports the movable body so that the movable body is capable of swinging, a spring member formed in a plate shape for urging the movable body toward the swing support point, a shake correction drive mechanism structured to swing the movable body with the swing support point as a swing center, a first stopper part which is protruded in a direction perpendicular to the optical axis direction on a front side in the optical axis direction of the movable body with respect to the spring member for determining a moving range of the movable body, and a second stopper part which is structured to face the first stopper part in the optical axis direction through the spring member on the rear side in the optical axis direction of the fixed body with respect to the spring member for determining a moving range of the movable body in the optical axis direction by restricting movement of the first stopper part.
