るスキユー補正機構。[Claims for Utility Model Registration] 1. An adjustment base on which the shaft of the turntable is supported is supported by an elastic member provided on the chassis, and multiple locations of the adjustment base are connected to adjustment screws with respect to the chassis. Therefore, the adjustment table is supported so that the interval can be adjusted, and there is a space between one part of the adjustment table and the chassis, when the adjustment table is adjusted in inclination according to changes in the tightening amount of each of the adjustment screws. A skew correction mechanism for an optical disc player, comprising a support portion serving as a fulcrum. 2. A pair of lenses capable of changing the amount of movement of the objective lens of the pickup facing the optical disk in a direction perpendicular to the movement line along which it moves for track scanning and in a direction opposite to the axis of the turntable. 2. The skew correction mechanism for an optical disc player according to claim 1, further comprising a pressing member, and the adjustment table is positioned between the pair of pressing members.
