[Effect of the idea]

In summary, the present invention provides a gasket on the upper surface of the other end of the joint body, positions the gasket between the bent portions, and uses the gasket to connect the side edges of the upper horizontal piece and the middle horizontal piece of the approximately S-shaped bent portion. Since the side opening formed at the edge is closed, the side opening of the bent part necessary for connection can be closed with a gasket, and even if rainwater enters the bent part of the end that engages outside the bent part, it can be closed. However, this can be prevented from penetrating into the folded part through the side opening of the folded part.
By adopting a connection form in which the bent end part is engaged with the bent part, water leakage that is likely to occur in such cases can be reliably prevented, and the top surface of the other end of the joint body protrudes outward beyond that edge. A gasket is provided, and a lower gasket wider than the gasket is provided on the upper surface of the upper end of the waste plate, and the gasket on the joint body side is positioned between the bent portions, and the gasket is placed on the upper side of the approximately S-shaped bent portion. The side opening formed by the side edges of the piece and the middle horizontal piece is closed, and the wide lower packing is in elastic contact with the lower edges on both sides of the packing of the joint body, so that the upper surface of the other end of the joint body is closed. The ends of the folded parts that are interposed between the bent parts of the surface structure material to which the packing is connected by protruding outward beyond the edges thereof and open to the side are connected to the side openings at the protruding parts of the packing. It sufficiently closes the deep part to prevent rainwater from entering the inside of the folded part of the surface structure material, and under such a packing, there is a lower packing that is wider than the packing and is placed on the upper surface of the board. The wide lower packing is in elastic contact with the lower edges on both sides of the packing on the joint body side, and can suppress water leakage from the lower edges on both sides of the packing part protruding from the joint body. There is an advantage that water leakage can be effectively prevented by using the gasket that protrudes from the bottom and the lower gasket that is wider than this.
