<P>PROBLEM TO BE SOLVED: To prevent floating of a connecting piece in assembly process, and to make a side plate and an end plate kept in a raised state. <P>SOLUTION: In an assembly box, the side plate 2 and the end plate 3 are respectively arranged continuously to two sides sandwiching a corner side of a bottom plate 1, and a corner plate 4 extending laterally from the side plate 2 and the corner side of the bottom plate 1 are connected by the connecting piece 5. Furthermore, the side plate 2 and the end plate 3 are raised from the bottom plate 1, and the corner plate 4 is bent obliquely from the side plate 2, and moreover, the connecting piece 5 is tucked in and superposed on the bottom plate 1. A locking protrusion 10 is arranged in an end edge facing the end plate 3 of the connecting piece 5, and a locking hole 11 is formed in the bottom part of the end plate 3, and moreover, the locking protrusion 10 is inserted in the locking hole 11 for retaining a shape. As the locking hole 11, a cut is made in the end plate 3 in an H-shape from a crease line of a boundary with the bottom plate 1. Along with rising of the end plate 3, the locking hole 11 is opened, and the locking protrusion 10 is pressed into the locking hole 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
