One end of each of a plurality of plate springs is fixed to an optical pickup body slidably supported by supporting shafts through sliding bearings, and each of a plurality of bearings is fixed to the other end of each of the plate springs. The bearings are pressed against the supporting shafts by the energizing force of the plate springs, and a force is applied to the optical pickup body by the pressing force of the bearings in a direction opposite to gravity.
