PROBLEM TO BE SOLVED: To enable side walls under laid down condition to stand rapidly, surely and approximately vertically. SOLUTION: A first female hinge member H1' consisting of a long hole h1 and a connecting hole h2 formed in a bank part 1a, a vertical slit h3 formed in an inside vertical part 1a1, and a hook h5 for preventing a vertical side wall from being raised up formed on a tongue piece h4 and arranged on a bottom part 1, is connected with a male hinge member H2 consisting of a supporting piece h10 hung down on a lower end flange 2a and a crosslinking block h11 and arranged on the side wall 2. A second female hinge member H1" consisting of a long hole and a connecting hole formed in a horizontal part of the bank part, a longitudinal vertical slit formed in the inside vertical part, and a hook h6 for preventing a horizontal side wall from being raised up formed on the tongue piece and arranged on the bottom part, is connected with a male hinge member H2 arranged on the side wall. As a result, as in the conventional case, there exists no possibility of bringing the engaging block into contact with the bank part of the bottom part, or running aground on the bank part. Therefore, it is possible to stand the side walls under laid down condition rapidly, surely and approximately vertically. COPYRIGHT: (C)2009,JPO&INPIT
