PURPOSE: To effectively increase a housing amt. by detaining one piece or plural pieces of housing boxes by means of detaining members to the rear surface of a rack constituted by coupling wires for a rack surface, wires for edges, wires for reinforcement and corrugated wires, etc.
CONSTITUTION: An article imposing surface is constituted by vertically and horizontally coupling plural pieces of the wires 11 for the rack surface. The wire 12 for the edge, the wire 13 for reinforcement and the corrugated wire 14 are coupled to the front edge of the article imposing surface to reinforce the article imposing surface and to prevent the forward dislodgment of the articles. Detaining bodies 15a, 15b facing the transverse direction are mounted to the lower side of the article imposing surface and the housing box 5 is inserted or taken out by sliding projecting parts 5a, 5b formed on both sides of the housing box 5. A desired number of the housing boxes 5 are provided. As a result, the housing amt. of the articles is effectively increased and the easy adjustment of the housing amt. is executed.
