PROBLEM TO BE SOLVED: To reduce heat quantity transmitted from an engine to an intake flow rate adjustment device through an intake member.SOLUTION: A saddle-riding type vehicle includes: an engine; an intake flow rate adjustment device adjusting a flow rate of intake suctioned to the engine; and a resin-based intake member 50 having an inner wall 51 forming a flow passage 54 guiding intake from the intake flow rate adjustment device to the engine. A center line 70 of the intake member 50 has a first circular arc part 71 and a second circular part 72 continued to each other. A first curvature center 71a of the first circular arc part 71 and a second curvature center 72a of the second circular arc part 72 are deviated from each other.SELECTED DRAWING: Figure 10
【課題】吸気部材を介してエンジンから吸気流量調整装置に伝達される熱量を低減すること。【解決手段】鞍乗型車両は、エンジンと、エンジンに吸い込まれる吸気の流量を調整する吸気流量調整装置と、吸気流量調整装置からエンジンに吸気を導く流路54を形成する内壁51を含む樹脂製の吸気部材50とを備える。吸気部材50の中心線70は、互いに連続した第1円弧部71および第2円弧部72を含む。第1円弧部71の第1曲率中心71aと第2円弧部72の第2曲率中心72aとは、互いに異なる位置にある。【選択図】図10
