<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a muffler, facilitating attachment of the muffler to an exhaust pipe by welding and having excellent welding quality. Ž<P>SOLUTION: Flanges 17a are formed by bending both ends 21 of a flat plate-shaped metallic plate 15 at a right angle. Then, a cylindrical shell 13 is formed by winding the metallic plate 15 with the flanges 17a positioned on the outer peripheral sides around an intermediate assembly 2 constituted by fixing end plates 3 to an inlet pipe 6 and an outlet pipe 7. After that, the flanges 17a and peripheral edges 10 of the end plates 3 are rolled and fixed. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
