A cylindrical member is fixed to an upper portion of a rotary shaft and a clamper presses an optical disc in contact with the top of a turntable. The structure is such that a first bottom face of the cylindrical member that faces a clamping magnet in the axial direction is positioned below an opposite face of the clamper that faces the clamping magnet in the axial direction.
