Further, at the positions of the fold lines b and c, there is a pair of front and rear cut lines 7 extending across the lines to the center positions of a and b and c and d, and connected by the cut line 6 between the fold lines c and d. A plurality of are arranged at required intervals.

The interval t1 between the pair of front and rear cutting lines 7 is a width suitable for fitting and supporting the supported object P, which is an equipment component, and the mutual interval t2 between the adjacent pair of cutting lines 7 is set to a width suitable for fitting and supporting the supported object P, which is an equipment component. The spacing is set such that the supports P do not come into contact with each other and a certain number of supports P can be arranged in parallel. By folding the unfolding plate 4 configured in this manner into a valley fold along the fold lines a and d and a mountain fold along the fold lines b, c, and e, a downward U-shape is formed on the left and right sides of the substrate 1. The hollow supporting parts 2, 2 and the sleeve pieces 3, 3 which stand up in a shape are integrally formed, and by mountain-folding along the fold line e, the left and right sleeves are formed by crossing the supporting parts 2, 2 from the back surface of the substrate 1. By overlapping the connecting pieces 8 up to the back surfaces of the pieces 3, 3 and gluing the overlapping surfaces, the hollow supporting parts 2, 2 are maintained in a rectangular tube shape.

In this way, the supporting parts 2, 2 and the sleeve pieces 3, 3 are integrally formed on the left and right sides of the substrate 1, and the connecting pieces 8
