PROBLEM TO BE SOLVED: To provide a branch joint capable of corresponding to various diameters and the thickness of a main pipe, and capable of securing water cut-off performance and fixability.SOLUTION: A branch joint is attached to an aperture drilling in a main pipe, and connects an auxiliary pipe to form a branch path. The branch joint includes: a cylindrical member that can connect the auxiliary pipe, includes a male screw on its periphery, and is inserted into the aperture of the main pipe; an outside fixing member that is screwed into the male screw from the outside of the main pipe; a flange part that is provided on the outer periphery of the cylindrical member, and covers the periphery of the aperture from the outside; and an inside fixing member that is screwed into the cylindrical member from the inside of the main pipe, and includes an inclination part contacting with the edge of the aperture from the inside of the main pipe. The branch joint holds the main pipe between the inclination part of the inside fixing member and the flange part. |
