PROBLEM TO BE SOLVED: To provide an oil supply part structure of a fuel supply pipe which inhibits deterioration of the volatile fuel suction efficiency during oil supply even if a drain hole is provided therein.SOLUTION: An oil supply part structure of a fuel supply pipe includes: a cylindrical part 12 having an oil supply port 18 and a connection port 20; a first flap mechanism 26 which is disposed at an oil supply port 18 side of the cylindrical part 12 and is pressed by a nozzle to open the oil supply port 18; a drain hole 24 formed at the cylindrical part 12 and allowing communication between an interior part and an exterior part of the cylindrical part 12; and a drain hole on-off valve 54 which opens or closes the drain hole 24. The drain hole on-off valve 54 is provided with an opening/closing mechanism 56 having a valve body part 50 which is pressed by the nozzle to close the drain hole 24 when the nozzle is inserted from the oil supply port 18 to supply oil.SELECTED DRAWING: Figure 1

    【課題】ドレン孔が設けられている場合であっても、給油時における揮発燃料の吸引効率の低下を抑制すること。【解決手段】給油口18と接続口20とを有する筒状部12と、筒状部12の給油口18側に配置され、ノズルによって給油口18を開く第1フラップ機構26と、筒状部12に形成され、該筒状部12の内部と外部とを連通させるドレン孔24と、ドレン孔24を開閉するドレン孔開閉弁54とを備え、ドレン孔開閉弁54は、給油口18からノズルが挿入されて給油する際、ノズルに押圧されてドレン孔24を閉じる弁体部50を有する開閉機構56が設けられている。【選択図】図1
