PROBLEM TO BE SOLVED: To limit a direction of oscillation of a muffler by a muffler support stay.SOLUTION: A muffler 31 and a bracket holder 28 are coupled via a muffler support stay 32. The muffler support stay 32 is formed of an inside member 37 and an outside member 38 being disposed in inside and outside directions of a vehicle, and respective lower parts of the members are welded to the muffler 31. The inside member 37 comprises a rigidity adjustment hole 58 thereon, and the outside member 38 does not comprise the same. By such a structure, during left revolving, because rigidity of the outside member which receives centrifugal force is high, and the inside member 37 which receives gravitation has lowered rigidity because of the rigidity adjustment hole 58, so that the muffler 31 oscillates inward. During right revolving, because the inside member 37 receives the centrifugal force, so that the muffler 31 oscillates inward. Therefore, the muffler support stay 32 limits an oscillation direction of the muffler 31 and improves revolving performance.SELECTED DRAWING: Figure 5 |
