PROBLEM TO BE SOLVED: To provide a board set that enables plate-like panels to be spread at a free relative angle for use without using any complicated hinge structures, the board set can be folded compactly and stored when not in use, and be carried.SOLUTION: A coupling body A has at least one pair of linear edges A12, A22 at peripheral edges of opposed surfaces A10, A20 facing each other with a plurality of coupling members A1, A2 folded, and uses a magnet as at least one of adjacent coupling members A1, A2 and a material to be attracted by the magnet as the other, the coupling members A1, A2 being coupled with magnetic force between the coupling members A1, A2 having the linear edges A12, A22 aligned with each other.SELECTED DRAWING: Figure 1 |
