To have abilities for oil supply and discharge of air in a fuel tank.SOLUTION: A fuel supply structure (1) includes: an inlet pipe (4) forming a circulation passage of a liquid fuel between an oil supply port (3) and a fuel tank (2); and a fuel inlet (5) connecting the oil supply port to the inlet pipe and forming a part of the circulation passage. The fuel inlet has: a cylindrical part (50) forming the part of the circulation passage; a nozzle insertion port (55) located at the inner side of the cylindrical part and having a diameter which allows an oil supply nozzle to be inserted thereinto; and a blowing back prevention part which is provided at an outer periphery of the nozzle insertion port and prevents blowing back of the liquid fuel from the fuel tank. The blowing back prevention part has: an annular plate part (54) which is formed at the inner side of the cylindrical part so as to enclose a periphery of the nozzle insertion port; and an air discharge part (59) which discharges air from the fuel tank. The annular plate part and the air discharge part are formed so as to overlap with each other when viewed in an axial direction of the circulation passage.SELECTED DRAWING: Figure 4

    【課題】給油性能と燃料タンク内の空気の排出性とを両立すること。【解決手段】燃料供給構造(1)は、給油口(3)と燃料タンク(2)との間で液体燃料の流通経路を形成するインレットパイプ(4)と、給油口とインレットパイプとを接続して流通経路の一部を形成するフューエルインレット(5)と、を備える。フューエルインレットは、流通経路の一部を形成する筒状部(50)と、筒状部の内側で給油ノズルを挿入可能な径を有するノズル挿入口(55)と、ノズル挿入口の外周に設けられ、燃料タンクからの液体燃料の吹き返しを防止する吹き返し防止部と、を有する。吹き返し防止部は、筒状部の内側でノズル挿入口の周囲を囲うように形成される環状板部(54)と、燃料タンクからの空気を排出する空気排出部(59)と、を有する。環状板部及び空気排出部は、流通経路の軸方向からみて互いに重なるように形成される。【選択図】図4
