Link body, folding structure provided with same link body, and separating member used for same folding structure

A tabular board including a link body and a plurality of board members, wherein

• the link body is provided with a plurality of link members,
• peripheral edges of the plurality of link members are linked to each other such that the plurality of link members are relatively rotatable up to 360°,
• a folded state where the plurality of link members overlap and a developed state where the plurality of link members are spread are established in a switchable manner by rotating the plurality of link members,
• at least one of the plurality of link members is overlapping and adjacent to the remaining plurality of link members, wherein the at least one of the plurality of link members comprises a magnet, and the remaining plurality of link members comprise a material attracted by the magnet,
• the plurality of link members are mutually linked by an attracting force of the magnet, in a state where linear edges provided along peripheral edges of facing surfaces that face each other in the folded state are aligned, through contact of the facing surfaces, and
• the plurality of board members are respectively provided with a storage recessed part to store at least one of the plurality of link members of the link body, at least one linear edge is included at a peripheral edge of a facing surface of at least one of the board members that faces in the folded state, and the at least one of the plurality of link members is arranged with the linear edge of the at least one of the plurality of link members being aligned with the linear edge of the board members.
