PROBLEM TO BE SOLVED: To provide a joining method and a joint structure, an assembling tool, and a suspension fitment in which a fitting-in work of a joint is rapidly ensured without noise airtightly even by a woman. SOLUTION: A duct joint structure is adapted such that at least two plate members of a duct are constructed such that they are perpendicular to each other viewed in a cross section, and an end part 1A of the one plate member 1 at the perpendicular part is bent so as to fitted to that angle where the two plate members are substantially perpendicular, and a U shaped groove 2A is formed in a tip end of the other plate member 2 to accomodate the bent part. A guide rail 3 protruding at an angle of 90 degree or less on the opposite side of the U shaped groove 2A with respect to an outer surface 2B of the plate member 2 is formed outwardly of the U shaped groove 2A part of the other plate member 2. |
