To provide an exhaust device of a vehicle which can prevent an exhaust pipe from interfering with a fuel tank at a rear collision of the vehicle by a simple structure.SOLUTION: In an exhaust pipe 13, a downstream-side muffler 16 adjoins a curved wall 8A at a front part 16a in a vehicle width direction, and a center axis C1 is inclined with respect to a center axis C of a vehicle 1 in a fore-and-aft direction, and installed so that a rear part 16b adjoins a side frame 3R in a vehicle width direction. The exhaust pipe 14 has a third exhaust pipe 19 extending frontward from a downstream-side muffler 16, and the third exhaust pipe 19 has a bent part 19A which is bent to the inside of the vehicle width direction so as to separate from a side frame 3R side so as to be located between the downstream-side muffler 16 and a fuel tank 6 in the fore-and-aft direction of the vehicle 1. An exhaust pipe support member 31 is installed between the bent part 19A and the downstream-side muffler 16 in the fore-and-aft direction of the vehicle 1, and between the third exhaust pipe 19 and the curved part 8A in the vehicle width direction.SELECTED DRAWING: Figure 2

    【課題】簡素な構造によって車両の後方衝突時に排気管が燃料タンクに干渉することを防止できる車両の排気装置を提供すること。【解決手段】排気装置13において、下流側消音器16は、前部16aが車幅方向で湾曲壁8Aに隣接し、かつ、後部16bが車幅方向でサイドフレーム3Rに隣接するように、中心軸C1が車両1の前後方向の中心軸Cに対して傾斜して設置されている。排気管14は、下流側消音器16から前方に延びる第3の排気管19を有し、第3の排気管19は、車両1の前後方向で下流側消音器16と燃料タンク6の間に位置するようにサイドフレーム3R側から離れるよう車幅方向内側に屈曲する屈曲部19Aを有する。排気管支持部材31は、車両1の前後方向で屈曲部19Aと下流側消音器16の間で、かつ、車幅方向で第3の排気管19と湾曲壁8Aの間に設置されている。【選択図】図2
