PURPOSE:To freely select a size and to make stacking-up possible, by connecting the connection parts of the divided parts of a side panel and the end edges of a bottom panel by hinges interposing a connection shaft folded in a three-axis direction between corner members. CONSTITUTION:A hinge part 18 is formed and fixed to the upper and lower side panels 14b, 14c of each side panel 14 along a dividing line and a hinge part 20 is formed and fixed to the corner part where the lower side panel 14c and a bottom panel 12 cross each other at a right angle from an inner surface side so as to straddle respective reinforcing frames 14a, 12a. The key-shaped part mutually engaged with the lower reinforcing frame 16 of each gate board 16 and the reinforcing frame 12a of the bottom panel 12 is provided and a key-shaped engaging part is provided between the reinforcing frames 14a, 16a at the side part where the upper side panel 14b and the gate board 16 cross each other at a right angle and corner members 26, 28 are fixed to four corner parts where the side panels 14b and the gate boards 16 cross each other at a right angle on the upper end side thereof. The upper horizontal shaft part 30b of a connection shaft 30 is loosely engaged with the sleeve 32 of the corner member 28 and a stopper 34 is mounted to the rear end thereof while the lower horizontal shaft member 30c of said shaft 30 is loosely engaged with the sleeve 36 provided on the side of the corner member 26 to be fixed by a stopper 38.
