PROBLEM TO BE SOLVED: To provide an inner joint of simple structure easily insertable into an eaves gutter body even if a clearance between the edge of the eaves and the eaves gutter is small, capable of preventing an adhesive agent applied to the outer surface thereof from being scraped off during the insertion, easily fittedly installable along the inner surface of the eaves gutter body, and capable of surely maintaining adhesiveness and sealability over a long period by the fitted installation. SOLUTION: This inner joint comprises a support rail part 40 having both side piece parts 41, 42 along the both side walls and bottom wall of the eaves gutter body and the bottom piece part 43 thereof which are formed integrally with each other and allowing the outer surface of the inner joint 4 to fit to the inner surface of the eaves gutter body. Each of the inner surface of the side piece part 41 on the front side of the eaves gutter body and the front side end of the support rail part 40 comprises engagement parts 40A, 41A engageable with and disengageable from each other. When they are disengaged, the inner joint 4 can be bent in the longitudinal direction. When they are engaged, the engagement part 40A at the end of the support rail part 40 is pushed up from the lower side and engaged with the engagement part 41A on the inner surface of the side piece part 41.
