PROBLEM TO BE SOLVED: To provide a fuel check valve improving attachment workability when attaching a valve element to a body section.SOLUTION: A fuel check valve 10 comprises a body section 20, a valve element 30 openably and closably attached to an opening of the same, and a spring member 60 biasing the valve element 30. The body section 20 has bearing parts 25 and 26 formed with shaft holes 25a and 26a, and the valve element 30 has a valve body 31 and a pair of support shafts 40 and 50 inserted in the shaft holes 25a and 26a. The support shafts 40 and 50 are coaxially supported on the valve body 31 via a deflectable connection part 35 in a state where base end portions 41 and 51 separate from each other, and extend from the connection part 35 for a predetermined length in a direction of separating from each other. Tips of the extending portions are inserted in the shaft holes 25a and 26a from the insides of the pair of bearing parts 25 and 26, respectively.

    【課題】本体部に対して弁体を組み付けるときの組付け作業性を向上させる、燃料逆流防止弁を提供する。【解決手段】この燃料逆流防止弁10は、本体部20と、その開口部に開閉可能に組付けられる弁体30と、弁体30を付勢するバネ部材60とを備え、本体部20は、軸孔25a,26aが形成された軸受部25,26を有し、弁体30は、弁本体31と、軸孔25a,26aに挿入される一対の支軸40,50とを有し、支軸40,50は、撓み可能な連結部35を介して、基端部41,51どうしが離間した状態で同軸的に弁本体31に支持され、連結部35から互いに離れる方向に所定長さで伸びており、この伸びた部分の先端部が、一対の軸受部25,26の内側から、軸孔25a,26aにそれぞれ挿入される。【選択図】図6
