Abstract:
1. A lens moving mechanism comprising: a lens frame which holds a lens; a guide shaft for slidably supporting said lens frame, said guide shaft extending parallel with an optical axis of said lens; a lead screw which extends parallel to the guide shaft for moving the lens frame linearly via a rotational force of said lead screw; a pair of bearing arms provided on said lens frame spaced from one another in a direction parallel with the guide shaft; and a screw-engagement follower which is located between said pair of bearing arms and is provided separately from said lens frame, said screw-engagement follower being provided with a screw-engagement portion which engages with said lead screw, wherein said guide shaft is relatively movably inserted in both said pair of bearing arms and said screw-engagement follower, and wherein said screw-engagement follower is integrally provided with an elastically deformable leg which elastically abuts against an inner surface of one of said pair of bearing arms to absorb play between said screw-engagement follower and said pair of bearing arms.
