Abstract

A lens driving device for use with a lens to photograph or image an object to be photographed or imaged may include a moving member holding the lens and made movable in the direction of an optical axis, and a supporting member for supporting the moving member through a spring member, wherein the lens is displaced and driven in the optical axis direction thereby to focus the image of the object. The supporting member may include a yoke having a cover portion having an entrance window for introducing the reflected light from the object into the lens, and a case portion for covering the outer circumference of the moving member. The cover portion and the case portion are formed integrally with each other.
