SADDLE-RIDING TYPE VEHICLE

To provide a saddle-riding type vehicle that is able to hinder scattering of foreign matter splattering from below a vehicle body.SOLUTION: A saddle-riding type vehicle comprises: a step floor 29 facing down from a vehicle; and a power unit U located behind the step floor 29 and causing a rear wheel WR to generate drive force. The step floor 29 comprises a lower surface part 29b1 extending in forward and backward directions of the vehicle and facing down from the vehicle. Between a rear end 29b2 of the lower surface part 29b1 and the rear wheel WR, a radiator cover 26a for the power unit U is provided. The radiator cover 26a comprises a water-impervious wall 73 projecting outward in the width direction of the vehicle. In a vehicle side view, the water-impervious wall 73 is disposed in an area A5 surrounded by a first virtual line extending in rearward upwardly from the rear end 29b2 of the rear part 29b of the lower surface, a second virtual line T4 passing through an axle AR of the rear wheel WR and parallel to the vertical direction of the vehicle, and a third virtual line T5 passing through the rear end 29b2 and parallel to the forward and backward directions of the vehicle.SELECTED DRAWING: Figure 21 【課題】車体下方から跳ね上がってくる異物の飛散を抑えることができる鞍乗り型車両を提供する。【解決手段】車両下方に臨むステップフロア２９と、前記ステップフロア２９の後方に位置し、後輪ＷＲに駆動力を発生させるパワーユニットＵと、を備え、前記ステップフロア２９は、車両前後方向に延びて車両下方に臨む下面部２９ｂ１を備え、前記下面部２９ｂ１の後端２９ｂ２と前記後輪ＷＲとの間には、前記パワーユニットＵのラジエータカバー２６ａを備え、前記ラジエータカバー２６ａは、車幅方向外側に突出する止水壁７３を備え、前記止水壁７３は、車両側面視において、前記下面後部２９ｂの後端２９ｂ２から後上がりに延びる第一仮想線と、前記後輪ＷＲの車軸ＡＲを通り車両上下方向に平行な第二仮想線Ｔ４と、前記後端２９ｂ２を通り車両前後方向に平行な第三仮想線Ｔ５と、に囲まれた領域Ａ５内に配置されている。【選択図】図２１
