2. Description of the Related Art Conventionally, a double joint for connecting an outer joint formed along an outer peripheral surface of an eaves gutter and an inner joint formed along an inner peripheral surface of an eaves gutter by sandwiching the eaves gutter from inside and outside. Joints are known, for example, as disclosed in Japanese Utility Model Publication No. 5-23695. That is, the eaves gutter joint disclosed in the above publication has a positioning projection 313 protruding from the upper end in the width direction center of both side walls 312 of the outer joint 31 and a side wall of the inner joint 32 as shown in a perspective view in FIG. A notch 323 into which the positioning protrusion 313 is inserted is provided at the upper end in the center in the width direction of the gutter 321, and the positioning protrusion 313 is provided so as to abut the connection end of the eave gutter 33.

[0003] However, in the case of a double joint which is applied to a structure in which the cross section of the eave gutter 33 has an opening at the top, such as the eave gutter joint shown in the drawing, the connecting portion is set from the upper side at the time of installation. Since it is difficult to visually check, it is difficult to accurately insert the positioning projections 313 provided on the outer joint 31 into the cutouts 323 provided on the inner joint 32. In particular, the cross-sectional shape has an opening narrowed upward. When connecting eaves gutters, it is more difficult to see the connection from above.
There is a problem that positioning by groping is not easy and it takes time to work.

[0004] Further, regarding an eaves gutter connection structure in which ends of the eaves gutter are sandwiched from inside and outside by an inner connector and an outer connector,
For example, it is known as disclosed in JP-A-4-368555. That is, what is disclosed in the above-mentioned publication, the ends of the eaves gutters are opposed to each other with a gap therebetween, and the inner connecting tool is fitted over the ends of both the eaves gutters and on the outer surfaces of the ends of the both eaves gutters. The outer connecting tool is fitted over the outer connecting tool, and the locking projection provided on the outer connecting tool is locked in the locking hole of the inner connecting tool through the gap between the ends of the two eaves gutters. In this way, the ends of both eaves are sandwiched.

[0005] However, in the above-mentioned connection structure, the ends of both eaves gutters can be firmly connected from inside and outside, and the inside connection member and the outside connection member can be connected so as not to be displaced from each other. When connecting eaves gutters having openings at the top, it is difficult to visually check the connection site from the top, so that there is a problem that positioning by groping is not easy and time is required for mounting work.

[0006]
