  As this type, there is one in which a side end portion of each panel and a connection bracket are connected by a connection means such as a fastening screw or a locking claw (see, for example, Patent Documents 1 to 4). According to these methods, it is possible to reliably connect the panels only by performing simple processing for connection to the panels. However, even when the panels are not connected, the processing for connection is exposed to the outside, and there is a problem that the appearance is bad. In addition, since the connection position is determined at the end of the panel, there is a problem that the degree of freedom of layout is limited.

In consideration of these problems, each panel is provided with an engagement groove having an inward projection on the opening edge, and each engagement groove has an engagement portion that can be engaged with the rear surface of the projection. Two panel abutting surfaces, which form a required angle with each other, are brought into contact with the surface of each panel, and each panel is engaged by each clamping body and the panel abutting surface. There is a panel connecting device in which each fastening body is fastened to a connecting material by fastening means with an inward protruding portion of a groove interposed therebetween (see, for example, Patent Document 5).
According to this connection device, the connection position of the panels can be changed to an arbitrary position, and the degree of freedom in layout can be improved. Even when the panels are not connected, the screw holes, the engagement holes, and the like are not exposed to the outside, and can be stored well.
