PROBLEM TO BE SOLVED: To provide a gutter linking structure which can prevent water leakage from a link portion using only an inner joint, and can enhance the appearance of the link portion of both gutters. SOLUTION: The gutter linking structure includes a gutter main body 1 which is comprised of a front surface plate 3, a rear surface plate 4, and a bottom surface plate 2. The front surface plate 3 has an inward protruding front lug 3c at its upper portion and a groove 3d formed in parallel therewith. The rear surface plate 4 has an inward protruding rear lug 3c at its upper portion and a groove 4b formed in parallel therewith. The gutter linking structure is constructed by abutting the internal peripheral surfaces of the front surface plate 3, the rear surface plate 4, and the bottom surface plate 2 on the external peripheral surface of an inner joint 5, and linking them together. The gutter main body 1 is formed by providing a bent portion 3a which bends the front surface plate 3 in an almost upper frontward direction, and an upward projecting bar 3b on the internal peripheral surface of the bent portion 3a. The inner joint 5 having a front plate 5b provided with a downward engaged groove 5d to be engaged with the projecting bar 3b, a rear plate 5c, and a bottom plate 5a, has its external peripheral surface abutted on the internal peripheral surface of the gutter main body 1, and the upper edges of the front plate 5b and the rear plate 5c are engaged with the grooves 3d, 4b, respectively.
