By the way, conventionally, in this gutter, at the point where a plurality of gutter merges, a temporary increase in water due to the confluence is received to prevent water from flooding the gutter. A catch basin (also called a rain catch basin) is provided for the purpose of collecting fallen leaves, garbage, and the like.

In addition, in this water collection box, it is connected to a storage tank as described in Patent Document 1, and is configured to drain part of the rainwater flowing through the side gutter to the storage tank during heavy rain. (hereinafter referred to as "conventional example").

In the conventional example, as shown in FIG. 13, a shuttering plate 63 having an upper end positioned higher than the inlet 64 is provided between the side wall 61 on the side of the inlet 64 and the side wall 62 on the side of the outlet 65. When the amount of water on the inflow port 64 side increases due to heavy rain or the like, and the amount of water exceeds the height of the dam plate 63, the water on the inflow port 64 side flows over the dam plate 63 and flows into the outflow port 65 side. It is configured to flow into the storage tank 70 through the outlet 65, thereby preventing flooding of rainwater in the gutter 50 and the catch basin 60 during heavy rain as much as possible.
