Claims

[Claims for Utility Model Registration] 1. At a gathering point of a plurality of exhaust pipes, each of the exhaust pipes is cut by an imaginary cutting plane passing through two points on the periphery of the opening, extending from the outer peripheral surface of the exhaust pipe to the opening. What is claimed is: 1. A gathering part of a plurality of exhaust pipes, characterized in that the outer shape is a parabolic virtual cutting line formed by the method, flanges are provided along the outer shape, and the flanges are joined so as to face each other. 2. The assembly of a plurality of exhaust pipes according to claim 1, wherein the flanges are extended inwardly of the respective exhaust pipes and joined together, and another exhaust pipe is fitted onto the joined portion. 3. The flanges according to claim 1, wherein the flanges are overlapped while facing each other, the overlapped portion near the exhaust pipe opening is welded, and the overlapped portion other than the welded portion is joined by brazing. A gathering point for multiple exhaust pipes.
