PROBLEM TO BE SOLVED: To provide a shelf that can be fixed only by inserting a lighting apparatus and a shelf board into a lateral groove or a hole of a wall and a display stand, and that can supply electricity, solving the problem that when a shelf is provided with a lighting apparatus, wiring needs to be provided for each shelf, which makes the work troublesome due to the wiring and causes significant inconveniences in that moving of the shelf after the completion of the work is not possible, and adjustment of the wiring is required every time the shelf is attached or detached.SOLUTION: A metal fitting with a lateral groove hole 1 is attached to a wall surface and a hooking metal fitting 3 is inserted and fitted into the hole, thereby holding a shelf board and supplying power simultaneously. The electricity contact surface is configured so that a contact failure hardly occurs because of the shelf pressure by the principle of leverage. |
