In the figure, 1 is an eaves gutter, 2 is a metal core material, and 3 is a hard synthetic resin such as polyvinyl chloride resin coated on this metal core material 2, and the metal core material 2 has a thickness of about 0.1 to 0.3 mm. The metal core material 2 is made of a thin steel plate, and the upper edges on both sides of the metal core material 2 are also inserted into the ears 4 on the upper edges on both sides of the eaves gutter 1. The metal core material 2 is provided with a large number of grooves 5 parallel to the longitudinal direction over the entire length of the metal core material 2, and the pitch between the grooves 5 is adjusted at the upper edges of both sides inserted into the ear portion 4. The pitch is said to be as small as about 1mm, and the pitch in the center is as large as 15mm. The grooves 5 are provided so that the radius of curvature of each part of the eaves gutter 1 corresponds to the pitch. The upper edges on both sides of the metal core material 2, which is inserted into the ear part 4 and has many grooves 5, have a corrugated plate shape due to the many grooves 5, and have high strength, and are particularly resistant to bending. It is strong against

対応する突条８を設けてもよい。 Next, the manufacturing method of this eaves gutter will be explained based on FIG. 4. First, a metal core is formed on one surface of a band-shaped metal core material 2, which is a hoop material, by a roll 7 made of hard urethane rubber and a concave-convex roll 6 facing the same. A large number of grooves 5 parallel to the longitudinal direction of the material 2 are recessed. At this time, the pitch between the grooves 5 is made small at both side edges and large at the center, but as shown in FIG. Even if the protrusions 8 are provided on the surface, as shown in FIG.
The first stage uneven roll 6a is provided with a protrusion 8 corresponding to the part with a large pitch in the center, and the next stage uneven roll 6b is provided with a protrusion 8 corresponding to a part with a small pitch on both ends. Good too.

ングロール９によつて容易に行なえる。 In any case, the metal core material 2 in which grooves 5 are formed on one surface by the uneven roll 6 is curved with the radius of curvature corresponding to the pitch of the grooves 5, with one surface facing the inner surface. In other words, it curves with a large radius of curvature at the center and a small radius of curvature at both ends. The metal core material 2 thus curved by providing the grooves 5 is further bent by forming rolls 9 so that each part has a desired curvature. It is preferable that these forming rolls 9 also be provided with protrusions corresponding to the grooves 5. By providing the grooves 5, the metal core 2 can be easily bent into a desired shape using a small number of forming rolls 9.

が容易となつているものである。 As described above, in the present invention, a metal core material is also inserted in the ear part, and the metal core material in the ear part is provided with grooves parallel to the longitudinal direction with a small pitch, and is shaped like a corrugated plate. Because of this, it has high strength and is resistant to thermal deformation, bending, and waving. Also, because the grooves have a pitch that corresponds to the radius of curvature of the eaves gutter, it is easy to form the metal core material into a gutter shape. The forming process is easy, especially since the concave side of the groove is on the inner surface of the metal core material, so the metal core material can be shaped like an eaves gutter due to the curvature of the metal core material due to the formation of the groove. Since the pitch of the grooves corresponds to the radius of curvature, it is easy to hold the metal core material during insert molding.
