The back wall 3 is so connected to the rear edge side bank part 14 of the bottom wall via a hinge mechanism H1 as to change over between an erecting position erecting to the bottom wall 1 and an inward falling position falling approximately in parallel onto the bottom wall 1. The left/right side walls 5 are so connected to the left-side and right-side bank parts 17 of the bottom wall respectively via hinge mechanisms H2 as to change over between an erecting position erecting to the bottom wall 1 and an inward falling position falling approximately in parallel onto the bottom wall 1.
