To improve the appearance of a saddle-riding type vehicle in which a catalyst is disposed in front of an engine, and to protect people around the saddle-riding type vehicle from heat of a catalyst case.SOLUTION: An exhaust device 31 of a saddle-riding type vehicle includes: a catalyst provided at an exhaust pipe and disposed in front of an engine; a catalyst case 41 connected to a middle part of the exhaust pipe and housing the catalyst; and a catalyst cover 71 facing the catalyst case 41 through a gap and covering the catalyst case 41. The catalyst case 41 has: a large diameter part 42 housing the catalyst 38; and a diameter reducing part 43 located at the downstream side of the large diameter part 42 and having a diameter smaller than that of the large diameter part 42. The catalyst cover 71 hooks on the large diameter part 42 and is fixed to the catalyst case 41 with a part thereof fastened to the diameter reducing part 43 with a bolt 86, etc.SELECTED DRAWING: Figure 11

    【課題】エンジンの前方に触媒が配置された鞍乗型車両の外観を良くし、かつ当該鞍乗型車両の周囲の者を触媒ケースの熱から保護する。【解決手段】鞍乗型車両の排気装置31は、排気管に設けられ、エンジンの前方に配置された触媒と、排気管の途中に接続され、触媒を収容する触媒ケース41と、触媒ケース41と間隙を介して対向し、触媒ケース41を覆う触媒カバー71とを備え、触媒ケース41は、触媒38を収容する大径部42と、大径部42の下流側に位置し、大径部42よりも縮径した縮径部43とを有し、触媒カバー71は、大径部42に掛け止めされ、かつ縮径部43にボルト86等により締結された状態で触媒ケース41に固定されている。【選択図】図11
