However, in the eaves water collector provided with a plurality of water stop protrusions around the drain outlet described in Patent Document 1, rainwater from the eaves hits the water stop protrusion and is guided to the drain outlet. Therefore, although the good drainage property is maintained, there is a problem that rainwater collected in the eaves trap 1 from the eaves fitting portion 7 leaks to the outside.

  That is, as shown in FIG. 7, there is a slight gap B between the step portion 21 of the outdoor side wall 6 and the bottom portion 19 of the ear portion 16, and rainwater on the step portion 21 of the outdoor side wall 6 shown in FIG. Flows into the bottom wall 2, but some of the rainwater moves in the direction of the arrows 23 and 24 and enters and accumulates in the B.

  Rainwater collected in the gap B of the ear portion 16 leaks outward from the gap B as indicated by arrows 25 and 26 in FIG. The leaked rainwater falls along the outdoor side wall 6 of the eaves collector 1 and the outdoor side wall 14 of the eaves collector 8 to cause the eaves collector 1 and the eaves 8 to become dirty. There was a problem of damaging the appearance of the eaves water collector, for example, as a drop from 1 part of the water collector and falling around the waterhole 11.
