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 when the nozzle is inserted from 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 64 which opens or closes the drain hole 24. The drain hole on-off valve 64 is provided with an opening/closing mechanism 34 having a valve body part 38 which closes the drain hole 24 in conjunction with an open operation of a first shutter member 28 of the first flap mechanism 26.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、ノズルが給油口18から挿入されたときに該ノズルに押圧されて給油口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64とを備え、ドレン孔開閉弁64は、第1フラップ機構26の第1シャッタ部材28の開動作に伴ってドレン孔24を閉じる弁体部38を有する開閉機構34が設けられている。【選択図】図1
