Description of the Related Art Conventionally, as shown in FIG. 5, an upper end mounting member (b) bent upward and outward is connected and extended to both upper edges of a shallow groove type gutter body (a). The valley gutters are known. The valley gutter is formed by bending a band-shaped plate made of a metal plate or an asphalt rubber-coated metal plate, and is provided on a roof or in a valley (e) between buildings to collect rainwater. Drain it. Normally, a single strip of sheet material is bent and the entire valley gutter is integrally formed. However, the width of the valley (e) at the construction site is wide, and this valley (e) In the case where it is not easy to obtain a strip-shaped plate having a width sufficient to integrally form the entire valley gutter corresponding to ()), the upper end of the gutter main body (a) is attached to the gutter main body (a) like this valley gutter. An upper end mounting member (b) is connected and extended. Also,
In this case, the upper edge of the gutter main body (a) and the upper end mounting member (b)
Is connected via a goby portion (c), and a connecting tool (d) such as a rivet or a screw is penetrated and connected to the goby portion (c). Also, in this valley gutter, the part of the gutter main body (a) is placed in the valley part (e),
The upper inclined portion of the upper end attaching member (b) is held by being fixed to the roof base surface (f) on both sides of the valley portion (e).
