PROBLEM TO BE SOLVED: To prevent scratch of an optical disk accompanied by sliding contact of an optical disk and a pressing member for attaching the optical disk to an attachment member caused by tilt transportation during insertion and discharge of the optical disk in an optical disk drive device inserting and discharging the optical disk through a slit of a case front plane. SOLUTION: In the pressing member 8 of a top plate 3 having possibility of sliding to the optical disk 7 when the optical disk 7 is inserted and discharged to/from the optical disk drive device, a slope 83 of a truncated cone type, and an opening inner peripheral plane 82 by drawing process are formed integrally and continuously by natural curvature by fabrication.
