記載の光ピツクアツプ。[Scope of Claim for Utility Model Registration] (1) A movable part of an objective lens drive device of an optical pickup, which movable part has a hole inserted into a shaft erected from a base, and a movable part for obtaining displacement corresponding to electromagnetic force. 1. An objective lens driving device for an optical pickup, comprising an elastic support member, the hole of the movable portion being brought into pressure contact with a shaft. (2) The movable part of the objective lens driving device has at least one pair of tracking coils that are rotated in a plane orthogonal to the optical axis of the objective lens, and has a first tracking coil that connects the centers of the pair of tracking coils. A first center line passes through the center point of rotation, and the elastic support member is disposed on a second center line that is orthogonal to the first center line through the center point of rotation. (1)
Light pick-up as described.
