PROBLEM TO BE SOLVED: To improve the air blowing performance and aerodynamic performance of a fan while securing mud-guard performance in a radiator structure of a saddle-riding type vehicle.SOLUTION: A radiator structure of a saddle-riding type vehicle comprises an engine supported on a vehicle body frame, a radiator 48 arranged forward of the engine, a lower end member 220 provided at the lower end of the radiator 48, and a fan 211 provided on the back face of the radiator 48. The lower end member 220 comprises a front face part 221a along the front face 48a of the radiator 48, a circular arc part 227 situated at the lower end of the front face part 221a, and a backward extension part 238 extending backward from the circular arc part 227. In the backward extension part 238, an opening 232 is provided in a portion situated radially outside of the fan 211, and louvers 222b, 222c, 222d are provided inside the opening 232.SELECTED DRAWING: Figure 8

    【課題】鞍乗り型車両のラジエータ構造において、泥除け性能を確保しながら、ファンの送風効果及び空力性能を向上できるようにする。【解決手段】車体フレームに支持されたエンジンと、エンジンの前方に配置されたラジエータ48と、ラジエータ48の下端に設けられた下端部材220と、ラジエータ48の背面に設けられたファン211とを備えた鞍乗り型車両のラジエータ構造において、下端部材220は、ラジエータ48の前面48aに沿う前面部221aと、前面部221aの下端に位置する円弧部227と、円弧部227から後方に延びる後方延出部238とを備え、後方延出部238においてファン211の径方向外側に位置する部分には開口部232が設けられ、開口部232の内側にはルーバー222b,222c,222dが設けられている。【選択図】図8
