    摘要: In an exhaust pipe connecting structure of a muffler, a through-hole 11a that penetrates one side wall portion of an outer shell 11 has a diameter larger than an outer diameter of an inlet pipe 2. The inlet pipe 2 is fixed at its portion corresponding to the through-hole 11a with a reinforcement-spacer member 3 having a cylindrical portion 31 that is gas-tightly connected with an outer circumferential surface of a projecting portion of the inlet pipe 2 and a flange portion 32 that projects outwardly from a through-hole side edge portion of the cylindrical portion 31. The flange portion 32 of the reinforcement-spacer member 3 is fixed by welding on an outer surface of the outer shell 11 all around the through-hole 11a. The cylindrical portion 31 of the reinforcement-spacer member 3 is fixed by welding on an outer circumferential surface of the inlet pipe 2 all around thereof. A stay 4 is provided with an insertion hole 41 coaxial with the cylindrical portion 31 of the reinforcement-spacer member 3 in a hollow part of the muffler main body, flange portions 43 at both end portion of a basal plate portion 42 of the stay 4 is fixed by welding on an inner surface of the outer shell 11. An end portion of the inlet pipe 2 is supported in a state where the end portion thereof is inserted in the insertion hole 41 of the stay 4.
