OPTICAL UNIT WITH SHAKE COMPENSATION FUNCTION

WIPO Patent Application WO/2012/032989

A1

Provided is an optical unit having a shake compensation function, the optical unit being capable of preventing plastic deformation of a spring member even when the spring member connects between a movable component and a stationary component. The optical unit (100) with the shake compensation function is adapted to have the spring member (600) connected to the movable component (10) and the stationary component (200) in order to rockably support the movable component (10) that holds a lens or the like. Between the spring member (600) and a rocking fulcrum (180) of the movable component (10) in the direction of an optical axis, a stopper member (290) is fixed on the inner circumferential surface of the stationary component (200) to restrict the amount by which the movable component (10) may be displaced in a direction intersecting the optical axis due to an external impact.
