FIG. 2 is an exploded perspective view showing a hard gutter different from FIG. 1 of the present invention. In FIG. 2, the hard gutter is a hard gutter comprising a building-side gutter 1 attached to an outer wall of the building, and an outer gutter 2 engaged with and fixed to the building-side gutter 1. 1 is provided with an engaging portion 3 and the outer gutter body 2 is provided with an engaged portion 4. By engaging the engaged portion 4 with the engaging portion 3, the building-side gutter body 1 and the outer gutter body 2 are connected to each other. And a fitting piece 6 is provided at each lower end of the building-side gutter body 1 and the outer gutter body 2 and a fitting piece 5 is provided at each upper end, and the fitting piece 6 is fitted to the fitting piece 5. They are connected in the longitudinal direction by being combined.

The difference from FIG. 1 is that the fitting piece 6 and the fitted piece 5 of the building-side gutter 1 and the outer gutter 2 are formed in a phased manner. The fitting piece 6 is formed on the hard gutter inner passage 8 side at the lower end of the building-side gutter body 1 and the outer gutter body 2 as a convex shape in a phased shape, and is formed as a concave shape on the outside of the hard gutter. The fitted piece 5 includes a building-side gutter 1 and an outer gutter 2.

The projecting shape of the phased fitting piece 6 provided at each lower end of the building side gutter 1 and the outer gutter 2 is the phase provided at each upper end of the lower building side gutter 1 and the outer gutter 2. Since the concave shape of the hollow piece 5 to be fitted is fitted exactly, a step is generated between the convex lower end of the fitting piece 6 and the convex upper end of the fitted piece 5 in this fitting portion. In addition, it is unlikely that the rainwater transmitted along the inner side of the hard gutter passage 8 of the building-side gutter 1 and the outer gutter 2 leaks out of the hard gutter outside this step. Further, since the fitting piece 6 and the fitting piece 5 are formed in a phased shape, the contact surfaces of the upper and lower outer gutter bodies 2 at the fitting portion are firmly fixed from the outer side of the hard gutter. Toward the gutter passage 8 side, since it is formed by three surfaces of a substantially horizontal surface, a substantially vertical surface, and a substantially horizontal surface, it is possible to prevent water leakage with good watertightness. In addition, since the outer surface of the hard gutter at the fitting portion of the upper and lower outer gutters 2 has no step and forms a continuous surface, the appearance can be made clear. Further, since the water blocking material 7 stops the water at the engaging portion 3 and the fitting portion between the building-side gutter 1 and the outer gutter 2, there is no water leakage. Further, the fitting piece 6 and the piece 5 to be fitted, which form the phase-adjusted shape, do not require a complicated manufacturing process such as a drawing process for reducing or expanding the diameter, and can be easily performed by cutting after extrusion. Can be formed.
