Further, in the embodiment, the case where the floppy disk is stored is shown, but the one to be stored, that is, the object to be stored is not limited to the floppy disk. In this case, it goes without saying that the rib spacing, the projection spacing, and the like are set according to the wall thickness of the stored object.

[0042]

The storage case of the present invention has the following effects.

(1) In the storage case of claim 1, the rib interval is set larger than the wall thickness of the object to be stored, and the projection interval is smaller than the wall thickness of the object to be stored. It becomes easier to insert the object to be housed between the ribs, as compared with the case where the rib interval is smaller than the thickness of the object to be housed.

The object to be stored inserted between the ribs is securely held by the projection. In particular, since the object to be housed is partially narrowed by the projection, even if the rib is curved or curved, it is possible to suppress distortion or deformation of the housed object due to the narrowing.

(2) In the storage case according to claim 2,
Instead of undercutting the entire rib as in the past, only the protruding part was undercut, so when molding the storage case with plastic, you can easily pull out the mold from between the ribs, and the storage case Can be manufactured more easily and easily.

(3) In the storage case according to claim 4 ,
Since the accommodation object insertion end side of the accommodation object inserted between the ribs is narrowed by the protrusion and the back plate side is narrowed by the rib, the accommodation object can be reliably held between the ribs without rattling.
