Abstract

A disk storage case comprising a main body and a cover body. The main body is for storing a disk-shaped medium therein and includes a bottom wall. The cover body is mounted on the main body in such a manner that it can be freely opened and closed. The bottom wall of the main body includes hold projections and guide projections. The hold projections are integrally formed in the center portion of the bottom wall of the main body so as to be engageable with a center hole formed in the disk-shaped medium to thereby be able to hold the disk-shaped medium. The hold projections are arranged in an annular manner. The guide projections are respectively provided between the hold projections. Further, the guide projections are integrally formed in the bottom wall of the main body and higher than the hold projections. A slit is formed and surrounding a part of a root portion of each hold projection to thereby allow the hold projection to be deformed elastically.
