PROBLEM TO BE SOLVED: To provide a fuel supply pump layout structure of a small-sized vehicle which does not influence on a structure of a vehicle so much by protecting a fuel supply pump mounted to an internal combustion engine with an existing main frame to avoid increase in size and weight of the internal combustion engine.SOLUTION: A main frame (4) extending backward from a vehicle body front part of a vehicle body frame (2) is within the lateral width of an internal combustion engine (20) provided under the main frame (4), in a plane view. A fuel supply pump (60) is between the main frame (4) and the internal combustion engine (20), and mounted to the internal combustion engine (20) so that at least a part of the fuel supply pump (60) is superimposed on the main frame (4) and positioned within the lateral width of the internal combustion engine (20) in a plane view.SELECTED DRAWING: Figure 3

    【課題】内燃機関に取り付けられる燃料供給ポンプを既存のメインフレームにより保護することで、内燃機関の大型重量化を避けて車両の構成に大きな影響を与えない小型車両の燃料供給ポンプ配置構造を供する。【解決手段】車体フレーム(2)の車体前部から後方に延びるメインフレーム(4)が、平面視で、該メインフレーム(4)の下方に設けられる前記内燃機関(20)の左右幅内にあり、燃料供給ポンプ(60)は、メインフレーム(4)と内燃機関(20)の間にあって、平面視で、該燃料供給ポンプ(60)の少なくとも一部がメインフレーム(4)に重なるとともに、内燃機関(20)の左右幅内に収まるように、内燃機関(20)に取り付けられる小型車両の燃料供給ポンプ配置構造である。【選択図】図3
