Abstract
A pickup supportersupporting a pickup deviceA includes a driverhaving an abutting surfacethat is a flat surface substantially in parallel to an axial direction of a lead screwand intersecting with both a focus direction and a plane direction substantially vertical to the focus direction. With such arrangement, even when a posture of the pickup supporteris changed by adjusting heights of the main shaftA and the sub shaftB, the screw abutting surfacecan abut on the lead screwat a substantially constant angle. Therefore, when the posture of the pickup supporteris changed, substantially constant driving force can be transmitted from the lead screw, so that stable and proper driving force can be constantly obtained.
