する光ピツクアツプのＹスキユー調整機構。[Scope of Claim for Utility Model Registration] An optical pickup main body that emits a beam to be imaged on a disk is connected to a fixed bearing section provided integrally with the optical pickup main body and a movable bearing section provided separately. In a Y skew adjustment mechanism for an optical pickup that is slidably attached to two guide shafts arranged parallel to each other, the tilt of the optical pickup main body with respect to the disk is adjusted by rotation of the movable bearing part. A movable bearing part is screwed to the optical pickup main body and has a threaded part that moves forward and backward in a direction substantially parallel to the central axis of the beam by rotation, and a threaded part that is perpendicular to the direction of movement of the threaded part. 1. A Y skew adjustment mechanism for an optical pickup, characterized in that the Y skew adjustment mechanism for an optical pickup is generally comprised of two flat plate parts that are attached to the guide shaft and slide into sliding contact with the guide shaft while facing each other with one of the guide shafts in between.
