PROBLEM TO BE SOLVED: To successively allow commodities in a chamber to appear on the front when a commodity located at the bottom is drawn out by forming front edges of inner side plates of a pair of right and left columnar cylinders in a J-shape to form a smooth edge, connecting the front edges of the right and left columnar cylinders to each other through a front plate to form a gap between the back side of the front plate and the smooth edge to be a chamber. SOLUTION: An outer plate 2 folded at right angles in the back surface direction on both sides of a front frame plate 1 through a ridge folding line is extended, a thick back plate 3 folded inward of its back edge at right angles is extended, and an inner side plate 4 folded at right angles in the front side direction is extended at an inside edge of this thick back plate 3 to form a pair of right and left columnar cylinders 5 of U-shaped section. An upper portion (at least one half) of the front edge of this inner side plate 4 is cut to form a J-shaped smooth edge 6, and a front end of the smooth edge 6 is raised to form a raised piece 9. Upper areas of the front edge of the outer side plate 2 are connected to each other by a PR front plate 7, a gap between the PR front plate 7 and the smooth edge 6 is formed to be a chamber 8, and a large number of commodities are accommodated in this chamber 8 in a stacked condition. |
