To provide an exhaust system having a guard member of an exhaust pipe, which is hardly deformed even when an external force is applied thereto, while protecting the exhaust pipe.SOLUTION: The exhaust device for motorcycle includes an exhaust pipe guard member (70) for guarding an exhaust pipe specified part (51P) from a first exhaust pipe part (54) extending in a first direction to a second exhaust pipe part (56) extending in a second direction via a curved exhaust pipe part (55). The exhaust pipe guard member (70) is formed of a rod-shaped member, and outside curved guard parts (71) formed along a curved outside face of the exhaust pipe specified part (51P) at an interval and lower guard parts (72) formed along an undersurface of the exhaust pipe specified part (51P) are constituted in a loop shape by connecting both ends thereof with one another by connection guard parts (73, 74). The exhaust pipe guard member (70) is characterized in that the vicinity of both the ends of each of the lower guard parts (72) is fixed to the exhaust pipe specified part (51P).SELECTED DRAWING: Figure 3

    【課題】排気管を保護しつつ、外力に対しても変形しにくい排気管のガード部材を備えた排気装置を供する。【解決手段】自動二輪車の排気装置において、第1方向に延びる第1排気管部(54)から湾曲排気管部(55)を経て第2方向に延びる第2排気管部(56)にかけての排気管特定部位(51P)をガードする排気管ガード部材(70)を備え、排気管ガード部材(70)は、棒状部材で形成され、排気管特定部位(51P)の湾曲外側面に間隔を空けて沿う外側湾曲ガード部(71)と排気管特定部位(51P)の下面に沿う下側ガード部(72)とが、互いの両端部を連結ガード部(73,74)により連結してループ状に構成され、排気管ガード部材(70)は、下側ガード部(72)の両端部近傍が排気管特定部位(51P)に固着されることを特徴とする。【選択図】図3
