PROBLEM TO BE SOLVED: To suppress introduction of ambient air into a fuel passage at the time of fuel supply.SOLUTION: A liquid discharge path communicates a fuel passage with the exterior via a liquid discharge port between an insertion side opening/closing valve mechanism for opening/closing an oil supply port and a fuel tank side opening/closing valve mechanism which opens/closes the fuel passage on a fuel tank side with respect to the insertion side opening/closing valve mechanism. The liquid discharge port of the liquid discharge path is opened and closed by a valve body of the opening/closing valve mechanism. The opening/closing valve mechanism has a movable body which is movable between a first position at which a closing force of the liquid discharge port is applied onto the valve body and a second position at which the closing force is reduced. This movable body is positioned at the first position in a stop state of a vehicle, and is moved to the second position when receiving an inertial force in association with travel of the vehicle.SELECTED DRAWING: Figure 8
【課題】燃料通路への外気の導入を燃料供給時において抑制する。【解決手段】排液路は、給油口を開閉する挿入側開閉弁機構とこの挿入側開閉弁機構よりも燃料タンク側で燃料通路を開閉する燃料タンク側開閉弁機構との間において、排液口を介して燃料通路を外部に連通する。排液路の排液口は、開閉弁機構の弁体により開閉される。そして、開閉弁機構は、弁体に排液口の閉鎖力を及ぼす第1ポジションと閉鎖力が低減する第2ポジションとの間を移動可能な移動体を有し、この移動体は、車両の停止状態において第1ポジションに位置し、車両の走行に伴う慣性力を受けると第1ポジションから第2ポジションに移動する。【選択図】図8
