PROBLEM TO BE SOLVED: To prevent breakage at the corner part of an eaves gutter due to tearing in two by making the thickness thick over the bottom part from one side wall disposed on the building side of the temperature zone of a curved joint positioned in the interior side of an eaves gutter connection part. SOLUTION: A curved joint 1 is composed of an L-shaped curved joint body 2 in planar view and eaves gutter connection parts 3, 3 integrally provided on both the ends of the curved joint body 2. In addition, the curved joint body 2 is composed of a bottom part 21, a front side wall 22 erected from both the sides of the bottom part 21 and a rear side wall 23. Falling into the joint inside of the rear side wall 23 of the curved joint body 2 is prevented even when the curved joint 1 is pulled by the contraction of an eaves gutter by making a part from the rear side wall 23 of the curved joint body 2 to the bottom part 21 thicker as compared with the other part in the interior side of both locking pieces 213. Thus, breakage of the curved joint due to tearing in two can be prevented.
