Abstract:
An optical unit with a shake correction function includes a fixed body, a movable body having an optical element, a swing support mechanism swingably supporting the movable body, a magnetic drive mechanism structured to swing the movable body, and a magnetic spring structured to return the movable body to a home position where a predetermined axial line and an optical axis of the optical element are coincided with each other. The magnetic spring includes a home position returning magnet disposed in one of the movable body and the fixed body, and an attracted member disposed in the other of the movable body and the fixed body so that a magnetic attraction force acts between the attracted member and the home position returning magnet. The attracted member and the home position returning magnet are disposed on the optical axis and face each other in a direction of the optical axis.
