PROBLEM TO BE SOLVED: To provide a nesting type rack of which the effective width is extended, which requires a less floor area when a large number of the racks are arranged in parallel, and of which the stacking stability is improved by a method wherein the inside interval between the right and left front columns, and height of the upper end, and the outside width of the loading floor are specified, and a V-shaped receiving apparatus is provided directly above the right and left front columns, and a fitting apparatus is provided directly under the right and left front columns. SOLUTION: If an inside interval between right and left front columns is taken to be W1 , and an outside interval between right and left rear columns 6 is taken to be W2 , it is expressed as W1 >W2 . Also, if the width of a loading floor 1 is taken to be W4 , it is expressed as W4 <W1 . An inside interval between right and left longitudinal beams 8 for the lower structure is equal to the inside interval W1 of the right and left front columns 5. Therefore, for this rack, a rack of the same structure can be housed inside as a nesting style. Then, a V-shaped fitting apparatus 2 is attached directly under the front columns 5 by a member, and a V-shaped receiving apparatus 3 with the same shape as the fitting apparatus 2 is attached directly above the front columns 5 by a square tube which is an intermediate member, and the fitting apparatus 2 and the receiving apparatus 3 are tightly fitted. Also, the longitudinal beams 8 of the upper rack are located on the outside of longitudinal beams 10 of the lower rack, and become stable under a state wherein the longitudinal beams 8 hug the longitudinal beams 10. |
