To reduce inflow resistance of a fuel without causing complication of a component shape of a passage formation member which guides a fuel to a fuel tank.SOLUTION: A check valve attached to a filler pipe attached to a fuel tank has: a valve body which opens or closes a fuel passage; and a valve body holding ring forming a valve seat of the valve body. The check valve is held by a check valve holding part. The check valve holding part holds the valve body holding ring at an opening of the fuel passage to position the valve seat at the opening of the fuel passage with a ring holding collar formed by expanding a diameter of a cylinder end part of a pipe holding cylinder attached to the filler pipe at the opening side of the fuel passage.SELECTED DRAWING: Figure 5

    【課題】燃料タンクに燃料を導く流路形成部材の部品形状の複雑化を招くことなく、燃料の流入抵抗を低減する。【解決手段】燃料タンクに装着されたフィラーパイプに組み付けられる逆止弁は、燃料流路を開閉する弁体と、弁体の弁座を形成する弁体保持リングとを有する。逆止弁は逆止弁保持部で保持され、逆止弁保持部は、燃料流路の開口側においてフィラーパイプに装着されるパイプ保持筒の筒端部が拡径して形成されたリング保持環により、弁体保持リングを燃料流路の開口に保持し、弁座を燃料流路の開口に位置させる。【選択図】図5
