PROBLEM TO BE SOLVED: To provide an inside connection-type gutter joint with good constructibility, without damage to the properties of drainage from a drain gutter of the gutter joint to an eaves gutter, even if sediment, dust and the like are accumulated on the periphery of a gutter lug on a front side. SOLUTION: This gutter joint comprises a groove-shaped joint body part whose outer surface is formed in a shape almost corresponding to a shape of an inner surface of a gutter body part, and a lug locking part which is provided at the upper end of the joint body part; a notched groove for discharging rainwater into the eaves gutter is provided in a rising piece which is positioned at the upper leading end of the lug locking part; a protrusion, which is formed in the upper part of the front side wall of the joint body part, functions as a weir; and notches are provided at both ends of a receiving surface serving as the bottom of the weir.
