PROBLEM TO BE SOLVED: To provide a storage case which can easily and reliably fix a center hole of a disk irrespective of an outer diameter of the disk and which can also be easily removed. SOLUTION: The disk fixing apparatus comprises a seat 5 having a predetermined height on an internal side surface of a storage tray 2 for the disk D, a receive 6 formed at the center of the seat 5 and a support rib 7 formed around the seat 5. The receive 6 has an outer diameter to be inserted into a center hole C of the disk D and is formed with a plurality of elastic locking pieces 8, 8, etc., radially extending from an upper portion of the receive 6 wherein their tips (balls 10) protrude more outwardly than the outer diameter of receive 6. The center hole C of the disk is brought into contact with an outer periphery of the receive 6 to push in the disk D, whereby a periphery of the center hole C of the disk D is locked by the tips of the respective elastic locking pieces 8, 8, etc,. while a lower surface of a periphery of the disk D is supported by an upper end of the support rib 7.
