The inner joint body is superposed on the inside and has both end edges inserted into the corresponding ear portions, and includes inner joint bodies provided with locking pieces that engage with both ends of the ear portions. The other end of the eaves gutter is an eaves gutter joint that is slidably sandwiched between the outer joint body and the inner joint body by sandwiching the stopper ridge, and at both ends of the inner joint body. It is characterized by an eaves gutter joint to which a strip-shaped sealing material having a sharp tip is attached.

Further, at one end, an eave and a main body are fitted and bonded to one eaves gutter ear and an eaves gutter main body, and the other eaves gutter ear is provided at the other end. An outer joint body having an ear portion fitted with the outer joint body, a stopper ridge provided at a central portion of an inner surface of the outer joint body, and an ear having a side edge corresponding to the side edge overlapped with the inner side of the outer joint body. The inner joint body which is inserted into the inner joint body and has an engaging piece that engages with the ear portion, and the end portion of the inner joint body is formed with an acute angled end strip. It is characterized by an eaves gutter joint to which a sealing material is attached.

Further, the invention is characterized by an eaves trough joint in which the length of the inner joint body in the longitudinal direction is longer than the length of the corresponding outer joint body in the longitudinal direction. It also features an eaves trough joint in which one or more openings are provided at the bottom of the outer joint body.

The sealing material is made of elastic rubber or soft plastic, and the eaves gutter joint in which the inner joint body, the outer joint body and the inner joint body and the outer joint body are integrated is made of metal or hard plastic. To be done.

The eaves trough joint in which the inner joint body and the outer joint body are integrated is used by adhering one side of the eaves trough joint to one eaves trough.

[0012]

[Operation] The strip-shaped sealing material, which is attached to the end of the inner joint body and has a sharp tip, seals the inner surface of the eaves trough, and the eaves trough connects the outer joint body and the inner joint body. When sliding between, scrape against the inner surface of the eaves gutter. This prevents dust, sand, etc. on the inner surface of the eaves trough from entering the eaves trough joint, and enables smooth sliding of the eaves trough.

Further, even if dirt and dust are accumulated inside the eaves joint for a long time, they are discharged as muddy from the opening provided at the bottom of the outer joint.
