PROBLEM TO BE SOLVED: To provide a fuel supply device whose layout is freely designed, in which a height of a sitting seat is prevented from being high by suppressing a height of the fuel supply device, and which is reducible in size without affecting the foot resting performance of a vehicle, in the small-sized vehicle in which a fuel tank is installed in a lower part of the sitting seat.SOLUTION: A fuel supply device comprises a discharge pipe 45 which accommodates a fuel pump 42a in a fuel tank 30, is attached to an external wall 30a of the fuel tank 30, and discharges fuel which is pressure-sent from the fuel pump 42a to discharge external piping 60, and a return pipe 46 which returns surplus fuel at a supply destination which is connected to the return external piping 61 to the fuel tank 30. The fuel supply device supplies the fuel to the supply destination from the fuel tank 30. The fuel supply device also comprises a flange part 43 which is located outside the fuel tank 30, a salient part 44, and a pressure regulation valve 50 accommodated in the salient part 44. The return pipe 46 is extended from a region which is overlapped on the pressure regulation valve 50 in the salient part 44 in a plane view.SELECTED DRAWING: Figure 9
【課題】着座シートの下方に燃料タンクを配置した小型車両において、燃料供給装置のレイアウトを自由にし、燃料供給装置の高さを抑制して着座シート高が高くなることを防止し、車両の足着き性に影響を与えずに燃料供給装置を小型化することが可能な燃料供給装置を提供する。【解決手段】燃料ポンプ42aを燃料タンク30の内に収容して、燃料タンク30の外壁30aに取り付けられ、燃料ポンプ42aから圧送された燃料を吐出外部配管60に吐出する吐出管45と、戻り外部配管61に接続され供給先の余剰燃料を前記燃料タンク30に戻す戻り管46を備え、燃料を燃料タンク30から供給先に供給する燃料供給装置において、燃料タンク30の外部に位置するフランジ部43と、隆起部44と、隆起部44の内部に収容される圧力調整弁50を備え、戻り管46は、平面視で隆起部44における、圧力調整弁50に重なる部位から延出させる。【選択図】図9
