PROBLEM TO BE SOLVED: To provide a fuel tank fueling section structure capable of suppressing vaporized fuel from being vigorously discharged from a fueling pipe when an on-off valve within the fueling pipe is opened.SOLUTION: A fueling section structure 24 of a fuel tank comprises: a filler pipe 26 that is an example of a fueling pipe comprising a fuel filler 26A into which a fueling nozzle 100 is inserted and communicating with the fuel tank; an outer cover 58 that is an example of an on-off valve provided in a flow passage 56 within the filler pipe 26 to close the flow passage 56, and opening the flow passage 56 when being pressed by the fueling nozzle 100; and a valve opening/closing device 86 that is an example of valve opening/closing means restricting or preventing the outer cover 58 from performing opening operation when a tank internal pressure of the fuel tank exceeds a preset set value, and allowing the outer cover 58 to perform the opening operation when the tank internal pressure is equal to or lower than the set value.SELECTED DRAWING: Figure 3

    【課題】給油管内の開閉弁を開放したときに、気化した燃料が給油管から勢いよく放出されるのを抑制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24は、給油ノズル100が挿入される給油口26Aを備え、燃料タンクに連通された給油管の一例としてのフィラーパイプ26と、フィラーパイプ26内の流路56に設けられて流路56を閉塞し、給油ノズル100に押圧されると流路56を開放する開閉弁の一例としての外側カバー58と、燃料タンクのタンク内圧が予め設定した設定値を超えている場合に外側カバー58の開放動作を制限又は阻止し、タンク内圧が設定値以下の場合に外側カバー58の開放動作を許容する弁開閉手段の一例としての弁開閉装置86と、を備えている。【選択図】図3
