PROBLEM TO BE SOLVED: To provide a fuel supply pump layout structure of a small-sized vehicle which can protect a fuel injection device from external force with an existing member, and can avoid increase in size and weight of an internal combustion engine, by displaying the fuel injection device in a proper space along with an intake passage of a cylinder head.SOLUTION: In fuel supply pump layout structure of a small-sized vehicle, a main frame (4) extending backward from a vehicle body front part of a vehicle body frame (2) passes through a part above a cylinder head (23), and an intake passage (40) leading suction air into a combustion chamber (30) is provided so as to extend from the cylinder head (23). A fuel injection device (50) is mounted on a side surface facing the main frame (4) on the cylinder head (23), and disposed along with the intake passage (40) in a vehicle body width direction.SELECTED DRAWING: Figure 2

    【課題】シリンダヘッドの吸気通路と並ぶ適切なスペースに燃料噴射装置を配置することで、燃料噴射装置を既存の部材で覆って外力から保護するとともに、内燃機関の大型重量化を避けることができる小型車両の燃料噴射装置配置構造を供する。【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、シリンダヘッド(23)の上方を通り、燃焼室(30)内に吸入空気を導く吸気通路(40)が、シリンダヘッド(23)から延出して設けられ、燃料噴射装置(50)は、シリンダヘッド(23)におけるメインフレーム(4)に臨む側面に取り付けられ、吸気通路(40)と車体幅方向に並んで配置される小型車両の燃料噴射装置配置構造。【選択図】図2
