FIG. 4 is a sectional view showing an eaves trough joint according to another embodiment of the present invention. In the eaves trough joint according to the embodiment, the difference from the eaves trough joint according to the above-described embodiment will be described. In the embodiment, the fitting guide piece 10 extending downward and forward is provided at the lower end portion of the hanging piece 12. It is provided. Further, the eaves trough 3 to be connected is of a so-called front height type in which the upper end of the front side wall 36 is higher than the upper end of the rear side wall 35. The joint 1 and the inner joint 2 are also higher on the front side than on the rear side.

In the eaves gutter joint according to the embodiment, the inner joint 2
When attaching, the fitting guide piece 10 is provided so that the rear side wall 25 of the inner joint 2 can be easily fitted into the gap between the hanging piece 12 and the rear side wall 15 of the outer joint 1, that is, the inner joint. When the inner joint 2 is slid from the upper front side of the eaves gutter 3 into the eaves gutter 3 by hooking the tip of the rear side wall 25 of the inner joint 2 onto the guide piece 10, the tip of the rear side wall 25 of the inner joint 2 is fitted. It is guided along the recessed guide piece 10 to the gap between the hanging piece 12 and the rear side wall 15.

In particular, in the eaves gutter 3 of the front height type as in the embodiment, since the rear side wall 35 is low, the tip of the rear side wall 25 of the inner joint 2 is placed in the gap between the hanging piece 12 and the rear side wall 15. Although it is slightly difficult to insert, such a problem can be solved by providing the insert guide piece 10. Further, in the eaves trough 3 of the front height type, the rear side wall 35 of the eaves trough 3 becomes even more difficult to see when the eaves trough 3 is constructed with the roof eaves draining on the upper rear side. . In such a case, in order to make it easier to confirm the mounting position of the inner joint 2,
If 12 is made larger, the hanging piece 12 becomes easier to see and the position can be easily confirmed, while the tip of the rear side wall 25 of the inner joint 2 is made to hang down.
Although there was a problem that it was difficult to insert it in the gap between 12 and the rear side wall 15, by installing the insertion guide piece 10, the insertion guide piece 10 can be easily seen without the enlargement of the hanging piece 12 The position can be easily confirmed, and at the same time, the tip of the rear side wall 25 of the inner joint 2 can be easily inserted into the gap between the hanging piece 12 and the rear side wall 15. As described above, the eaves gutter joint according to the embodiment becomes easier to construct.
