PROBLEM TO BE SOLVED: To provide a fuel tank fueling section structure capable of reducing the quantity of liquid fuel residing on an on-off valve.SOLUTION: A fueling section structure 20 of a fuel tank comprises: a filler pipe 22 that is an example of a fueling pipe comprising a fuel filler 22A into which a fueling nozzle 100 is inserted, and feeding liquid fuel supplied from the fueling nozzle 100 to the fuel tank; an on-off valve 26 provided in a flow passage 24 within the filler pipe 22 to close the flow passage 24, and opening the flow passage 24 when being pressed by the fueling nozzle 100; an accommodation section 60 provided outside of the filler pipe 22, accommodating therein adsorbent 58 adsorbing gaseous fuel formed by evaporating the liquid fuel, and communicating with the flow passage 24 on a side closer to the fuel filler 22A than to the on-off valve 26 so that the liquid fuel can flow into the accommodation section; an atmospheric passage 62 communicating the accommodation section 60 with the atmosphere; and a gas moving passage 64 communicating the accommodation section 60 with an engine 104 for moving gas within the accommodation section 60 to the engine 104 by negative pressure from the engine 104.SELECTED DRAWING: Figure 1

    【課題】開閉弁上に溜まる液体燃料の量を低減できる燃料タンクの給油部構造を提供する。【解決手段】燃料タンクの給油部構造20は、給油ノズル100が挿入される給油口22Aを備え、給油ノズル100から供給される液体燃料を燃料タンクへ送る給油管の一例としてのフィラーパイプ22と、フィラーパイプ22内の流路24に設けられて流路24を閉塞し、給油ノズル100に押圧されると流路24を開放する開閉弁26と、フィラーパイプ22の外側に設けられ、内部に液体燃料が気化した気体燃料を吸着する吸着材58を収容し、開閉弁26よりも給油口22A側で流路24と連通して液体燃料が流入可能とされた収容部60と、収容部60を大気に連通させる大気通路62と、収容部60とエンジン104とを連通し、エンジン104からの負圧により収容部60内の気体をエンジン104に移動させるための気体移動通路64と、を有する。【選択図】図1
