PROBLEM TO BE SOLVED: To prevent the deterioration of appearance quality by concealing the cut surface of the edge section of an upper wall panel in a joiner sealing a horizontal joint between upper-lower wall panels. SOLUTION: One metal plate is bent, a surface section 2p, a connecting section 2r and a rear section 2q having double-layer structure are molded integrally, and both the surface-side lower edge section of an upper wall panel 1 and the surface-side upper edge section of a lower wall panel 1 can be covered as the structure of the surface section 2p. A gap (n) is formed between the double layers of the connecting section 2r by a rib R formed to the connecting section 2r while a gap (m) is also formed to the surface section 2p, a drain hole H is shaped to the upper-layer root section of the connecting section 2r continuously connected to the surface section 2p, and rainwater or the like is discharged through the gaps (n), (m).
