Abstract:
A lens moving device comprising:a lens support mechanism that supports a lens in such a manner that said lens moves along the optical axis thereof; a drive source that moves said lens along the optical axis; a cam member that is rotated by said drive source, said cam member being molded from synthetic resin and being provided with a stopper and a ring-shaped cam surface that includes an operative area and a non-operative area, said operative area having a portion which is inclined with respect to a plane perpendicular to the optical axis of said lens; and a cam follower that comes in contact with said cam member to transmit the rotational movement of said cam member to said lens support mechanism as a linear movement of said lens along the optical axis; wherein said cam follower comes into contact with said operative area of said cam surface during an normal operation and does not come in contact with said non-operative area of said cam surface during a normal operation, said non-operative area having a gate mark formed during the resin molding process, said stopper preventing said cam follower from interfering with said gate mark.
