PROBLEM TO BE SOLVED: To provide a safe equipment case showing a superior recycle characteristic which can be easily disassembled even if the case is connected by special screws or the like. SOLUTION: This equipment case is constructed such that each of hubs at each of case inner surfaces is protruded from each other in such a way that their distal end surfaces are abutted on each other; the diameter of one hub is made larger than that of the other hub except the abutted portions at the distal ends; a hole is notched at one hub, a seat portion is formed at the distal end, a protruding portion abutted against the other hub is protruded out of the seat portion; a clearance between a base end of the protruding portion and a bottom surface of the hole is set to have a thin thickness; a through-pass hole for a screw is penetrated through the seat portion; a hole is made at a location opposing to the through-pass hole; a screw is inserted through the hole at one case and threadably engaged with the hole in the other case. |
