According to the structure of the first aspect of the present invention, the decorative edge material is bent and formed as in the conventional case, but the side wall portion of the hollow portion becomes the inside of the bend without being disassembled. It can be bent as a unit. During this bending process, the decorative edge material is formed in a substantially symmetrical manner with the upper and lower parts sandwiching the center line that crosses the center of the hollow part, so that a uniform bent state can be realized. Further, since the ridges are formed parallel to each other along the longitudinal direction of the flat plate-shaped side wall portion corresponding to the inside of the bending of the hollow portion, the rigidity of the side wall portion is increased, so that the side wall portion is crushed during bending. There is no such thing as a bend.

According to the structure of the second aspect, the molding can be carried out in a state in which the molding piece is engaged with the concave portion or the convex portion formed continuously in the longitudinal direction. Bending can be performed stably without deformation.

According to the structure of the third aspect, since the hollow portion is formed in a semicircular shape, it can be composed of a semicircular arc portion and a side wall portion, and a portion having a large degree of deformation is a semicircular portion. Since it is formed in a circular shape, there are less stress-concentrated portions than when the cross section is rectangular. Therefore, the deformation is not biased and the finish is neat.

According to the structure of the fourth aspect, since the mounting edge is formed so as to project at a portion corresponding to the indoor side of the hollow portion, the mounting property to the lower end draining portion of the wall body is particularly good.

According to the structure of the fifth aspect, since the decorative edge material is formed on the outdoor side of the parapet at the top of the parapet, the decorative edge can be constructed using the umbrella tree. It's easy.
