According to the storage of the present invention, the left and right side walls 4
In addition to connecting the back wall 5 to the back wall 5 so that it can be folded inward, the back wall 5 is further composed of left and right back walls 5a and 5b and a stud 22 so that the back wall 5 can be folded into two. Accordingly, the entire peripheral panel 6 can be folded and packed in a small size, and the packing style at the time of packing can be reduced accordingly, so that the cost required for transportation and the storage space in stock can be reduced. Since the packing kit can be miniaturized, it is possible to take the packing kit purchased by the user back home and immediately assemble and use it without waiting for delivery by truck or the like. Since the left and right side walls 4 and 4 and the left and right back walls 5a and 5b are folded in parallel, the shape of the packing with the molded cushion can be simplified, and the labor and time required for the packing operation can be reduced, and the shape of the molded cushion can be simplified. In addition to what can be done, the cost required for packaging as a whole can be reduced.

Since the left and right back walls 5a and 5b are connected via the studs 22, the structural strength of the back wall 5 in an assembled state can be increased, and a robust storage without rattling can be obtained.
