クアツプ駆動装置。[Claims for Utility Model Registration] (1) A light consisting of a worm gear attached to the rotating shaft of a motor, a rotating body that meshes with the worm gear, and an optical pickup mounting board on which a rack gear that meshes with the rotating body is attached. In the pick-up drive device, the rotating body is composed of two rotating bodies, and a single elastic member is provided between the rotating bodies to alleviate horizontal and vertical backlash with the rotating body caused by the lead angle of the worm gear. An optical pick-up drive device that is worn on the body. (2) The elastic body is a ring-shaped elastic body having a free end, and the elastic body is bent back and forth around a portion facing the free end to generate a force that alleviates the vertical crush. An optical pickup drive device according to claim 1 of the utility model registration claim.
