PROBLEM TO BE SOLVED: To provide an exhaust device of a scooter type vehicle, in which a catalytic converter in an exhaust muffler is arranged avoiding a concavity for rear wheel recess of a required size and depth so that replacing work of a rear wheel can be performed without removing the exhaust muffler while keeping a satisfactory appearance and avoiding increase of a vehicle body in size.SOLUTION: In an exhaust device of a scooter type vehicle, at the side on the opposite side to a power transmission mechanism (31, 33) arranged on one side of a rear wheel (40), an exhaust muffler (71) equipped with a catalytic converter (90) in the inside is arranged, and at a part in an inner wall (73a) of the exhaust muffler (71) on the rear wheel (40) side, which a rear wheel axle (35) faces, a concavity (73P) for rear wheel recess is formed. In the exhaust device, the catalytic converter (90) is disposed forward of the concavity (73P) for rear wheel recess in the exhaust muffler (71).SELECTED DRAWING: Figure 7
【課題】排気マフラー内の触媒コンバータが、必要な大きさ・深さの後輪逃げ用凹部を避けて配置されることで、良好な外観性を維持し車体の大型化を避けながら排気マフラーを取り外すことなく後輪の交換作業ができるスクータ型車両の排気装置を供する。【解決手段】後輪(40)の一側方に配設される動力伝達機構(31,33)と反対側側方に、内部に触媒コンバータ(90)を備えた排気マフラー(71)が配設され、排気マフラー(71)の後輪(40)側の内側壁(73a)における後輪車軸(35)が臨む部位に、後輪逃げ用凹部(73P)が形成されるスクータ型車両の排気装置において、触媒コンバータ(90)が排気マフラー(71)内の後輪逃げ用凹部(73P)よりも前方に配置される排気装置。【選択図】図7
