PROBLEM TO BE SOLVED: To provide a returnable case which is easily assembled and disassembled, and does not rattle after assembly. SOLUTION: The recess 45 of the supporting plate 42 of a connecting part 40 on the far side from a worker is fitted with a vertical member 22 of a frong frame 2 for positioning and then the connecting part 40 is pressed from a diagonally upper part against an upper member 21 on the front frame 2. A roof beam 4 is pushed forward as indicated by the arrow in this condition. Then the plate 42 opens against a spring 43 by the member 21, and the top end of the member 21 goes into an opening opened at the bottom of a fitting part 41. By lowering the roof beam 4 as indicated by the arrow from this condition, the member 21 is fitted in the part 41. COPYRIGHT: (C)2006,JPO&NCIPI
