PROBLEM TO BE SOLVED: To prevent fuel from leaking outside even when the fuel flows back at the time of an automatic stop operation during refueling.SOLUTION: A fuel supply portion structure of a fuel supply pipe includes: a tubular portion 12 having a filler port 18 and a connection port 20; a first flap mechanism 26 which is provided on the filler port 18 side of the tubular portion 12 and which is pressed by a nozzle to open the filler port 18 when the nozzle is inserted from the filler port 18; a drain hole 24 formed in the tubular portion 12 and for communicating the inner space of the tubular portion 12 with outside; and a drain hole on-off valve 66 for opening and closing the drain hole 24. The drain hole on-off valve 66 is disposed on a placement surface located at the lowermost side of a vehicle on an inner wall of a first inner diameter member 60. The placement surface is made of an inclined surface 70 falling from the filler port 18 side toward the connection port 20 side with respect to a horizontal plane H of the vehicle, and a wall portion 72 rising toward the filler port 18 side is provided on the filler port 18 side of the inclined surface 70.SELECTED DRAWING: Figure 1
【課題】給油中のオートストップ作動時に燃料が逆流しても外部に漏出することを抑制すること。【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66とを備え、ドレン孔開閉弁66は、第1内径部材60の内壁で最も車両下方側に位置する配置面に配置され、配置面は、車両水平面Hに対して給油口18側から接続口20側に向かって立ち下がる傾斜面70からなり、傾斜面70の給油口18側には、給油口18側に向かって立ち上がる壁部72が設けられている。【選択図】図1
