PROBLEM TO BE SOLVED: To provide a gutter structure which makes an elbow unnecessary, makes a down-pipe inconspicuous, and can obtain beautiful finish in terms of external appearance. SOLUTION: A wing wall 8 orthogonal to the eaves direction is provided below the eaves edge 2 of a roof 1, and the down-pipe 15 is attached at the side end of the wing wall 8. Then the upper end of the down-pipe 15 is connected to the section of the eaves gutter 5 which is in proximity to the upper end of the wing wall 8. By this, the down-pipe 15 can be made more inconspicuous than the case that the down-pipe is attached on the external wall 3 of a building, and beautiful finish in terms of external appearance can be obtained. Furthermore, since the down-pipe 15 is attached at the side end of the wing wall distance between the upper end of the down pipe 15 and the eaves gutter 5 can be made short. Since the upper end of the down-pipe 15 is connected to the section of the eaves gutter 5 which is in proximity to the upper end of the wing wall, the need for the elbow can be eliminated. A beautiful finish in terms of external appearance can also be obtained in this point. COPYRIGHT: (C)2011,JPO&INPIT
