The base piece 4 is provided with a locking protrusion 6 that projects upward by bending the center part, and the gap closing member 3 has the locking protrusion 6 recessed in the side end surface of one of the exterior members 1a. The decorative piece 8 is disposed between the side end surfaces of adjacent exterior materials 1 by engaging with the groove 10 and engaging with a recess 9 provided in the full end surface of the other exterior material 1b. At this time, the width of the concave groove 7 is made larger in consideration of the positioning of the gap closing member 3 and the positional shift due to the spring property. The length a of the decorative piece 8 is larger than the distance between the base piece 4 and the abutting piece 5, so that the abutting piece 5 is brought into pressure contact with the side end surface of the other exterior material 1b. When the gap closing member 3 is arranged between the side end faces, the decorative piece 8 is reliably positioned within the recess 9. The length a of the tab, wa, and decorative piece 8 is larger than the width of the joint A, which is the height between the base piece 4 and the abutting piece 5, so that the decorative piece 8 can fit into the recess. 9, the joint A is closed. A folded piece 11 is provided at the tip of the contact piece 5 and the tip of the decorative piece 8 by folding back. If the metal gap closing member 3 is placed at the outdoor side entrance of the joint A as described above, it is possible to make the joint A a fireproof structure. By arranging the packing material 2, waterproof performance can be ensured, and the joint WSA can be made into a fireproof structure, and the waterproof property can be improved. Also, since the contact piece 5 is pressed against the side end surface of the other exterior material 1b against the spring force, the joint area A
Furthermore, even if the exterior material 1 is misaligned, the contact piece 5 will remain in contact with the side end surface due to its spring properties, which will prevent the exterior material 1 from misaligning. can be followed.
