Abstract

PURPOSE:To facilitate the altering adjustment of a bending angle, and to maintain a sharp outside appearance, and to reduce manufacturing cost. CONSTITUTION:Peripherally cornice-shaped bendable parts 3 are severally provided near both the eave gutter connecting parts 2 of an elbow body 1, and both the bendable parts 3 are united at the inside wall corner part 4 of the elbow body 1. In this case, since both the bendable parts 3 are severally provided in a peripheral direction being rectangular to the longitudinal direction of the eave gutter, a vertical bending angle is easily altered and adjusted, and since the bendable parts 3 are united at the inside wall corner part 4 of the elbow body 1, the horizontal bending angle is also easily altered and adjusted. In addition, since the bendable part 3 does not appear at an outside wall corner part, a sharp outside appearance is not impaired, and since both the bendable parts 3 are united without separation, cost reduction is realizable in materials and manufacture.

However, there is a problem in any of the above conventional examples. That is, in the eaves gutter bending shown in FIG. 9, a bellows-like bendable portion (b)
Since it is provided in the circumferential direction inclined with respect to the longitudinal direction of the eaves gutter (d), it is difficult to change and adjust the bending angle in the vertical direction b, and the bendable portion (b) has an outside angle. Since it appears in the section, the sharp appearance of the eaves gutter is lost. Further, in the eaves gutter bending shown in FIG. 10, since both bendable portions (b) are provided in the circumferential direction orthogonal to the longitudinal direction of the eaves gutter (d), the bending angle in the vertical direction b is changed and adjusted. Although it is easy to do, it is difficult to change and adjust the bending angle in the horizontal direction a because there is no bendable part (b) at the corner, and both bendable parts (b) are independent. However, there is a problem in terms of material and manufacturing cost.

The present invention has been invented to solve the above-mentioned problems in the prior art. That is, the problem is that the bending angle can be easily changed and adjusted in both the vertical and horizontal directions, and the sharp appearance is impaired.
