BACKGROUND ART Conventionally, assembled furniture such as shelves, which uses panels as shelf boards or side boards and is configured by combining a plurality of panels, has been widely used. Some of these prefabricated furniture are those that are assembled at the factory and those that are knocked down by the user. A synthetic resin material or the like is often used for the panel of the assembled furniture, and the panel has a hollow structure for weight reduction or the like. To reinforce the strength of the panel, it is necessary to install a reinforcing material such as a metal rod. Further, in order to increase the strength of the assembled furniture itself, it is essential to secure sufficient connection strength between the shelf plate and the side plates. Therefore, in order to obtain the bonding strength of the connecting portions such as the shelf panel and the side panel, a male screw shaft and a bar are provided as a reinforcing material, and the male screw shaft is passed through the shelf panel and the side panel to end each panel end. There is proposed a structure in which a shelf plate panel and a side plate panel are coupled to each other by inserting the protruding portion into a rod and inserting the protruding portion into the rod.
