PROBLEM TO BE SOLVED: To prevent water leakage by forming an inside gutter part between a water above side roof part and a water under side roof part, constituting a gutter main body of an upper part opening almost groove-shaped gutter part and a water under side extending part extending to the water under side, and covering the water above side upper end. SOLUTION: A recessed groove part 2 is formed in a building frame 1 of a roof structure, a cemented excelsior board 3 is laid on the water above side ground surface 1a of this recessed groove part 2, and an inside gutter part 9 is formed in the recessed groove part 2. A long size gutter main body 10 for forming this inside gutter part 9 is formed of an upper part opening almost groove-shaped gutter part 10a, a water above side extending part 10b and a water under side extending part 10c. Next, the water under side extending part 10c covers a ridge side engaging part 5b and a receiving metal fitting 7, a capillary phenomenon preventive space 11 is formed between the water under side extending part and a water under side laterally roofing roof, and the water above side extending part 10b is fixed by a fixing tool 12. A long size arabesque and throating member 14 is arranged on the water above side extending part 10b of a gutter main body 10 to be fixed by the fixing tool 12 together with the water above side extending part 10b to thereby prevent oveflowing water from leaking to an eaves edge ceiling part. |
