Abstract
A lens moving device comprises a cam follower which is provided to a lens holding frame supporting a lens, and a cam gear with which the cam follower is engaged. The cam gear is rotated by a stepping motor, so that the lens holding frame and the lens move along the optical axis thereof. The cam gear is molded from synthetic resin and is provided with a stopper at the both ends of a non-operative area, in which the cam follower does not come in contact during a normal operation. The non-operative area has a gate mark, which is formed during the resin molding process. The stopper prevents the cam follower from interfering with the gate mark.
