Abstract
A lengthwise-direction driving frame is supported in an opening of a flange by holding members, being slidable in a lengthwise direction. The opening of the flange includes inner walls parallel to the lengthwise direction. A lateral-direction driving frame, which holds correction lenses, is supported in an opening of the lengthwise-direction driving frame, being slidable in a lateral direction. The opening of the lengthwise-direction driving frame includes inner walls parallel to the lateral direction. A tip of a shaft of a lengthwise-direction actuator abuts at all times against a pressed member which is fixed on the lengthwise-direction driving frame. A tip of a shaft of a lateral-direction actuator abuts at all times against a pressed member which is fixed on the lateral-direction driving frame. The lengthwise-direction and lateral-direction actuators are respectively fixed on the flange.
