PROBLEM TO BE SOLVED: To suppress that a guard bracket interferes with a flexible pipe when the guard bracket is upwardly displaced with its one end as a pivot.SOLUTION: A guard bracket 7 extending to a flow direction of exhaust emission at a lower side of a flexible pipe 3 which is connected to a first end 3a of a first exhaust pipe 2 is arranged between the pipe 3 and the first exhaust pipe 2 with a clearance S. An end E1 of the guard bracket 7 is fixed to a portion apart from the first end 3a in the first exhaust pipe 2. Then, a stopper 9 is arranged at a portion between the first end 3a and the end E1 in the clearance S. The stopper 9 protrudes toward a first point P1 at the guard bracket 7 side in the portion of the clearance S from a second point P2 at the first exhaust pipe 2 side. Furthermore, the stopper 9 has a protrusion amount X abutting on the first point P1 prior to the arrival of the guard bracket 7 at the flexible pipe 3 when the guard bracket 7 is upwardly displaced with the end E1 as a pivot.SELECTED DRAWING: Figure 2 |
