To suppress protrusion of an outer body to an outside of a device while securing liquid discharge property of an opening/closing device for a fuel tank.SOLUTION: A housing for surrounding a nozzle insertion passage comprises a first opening for opening the nozzle insertion passage into atmosphere, a cover body in which the housing is incorporated comprises a nozzle insertion hole and a second opening which is opened into atmosphere and faces the first opening. In addition, a liquid discharge mechanism attached to the housing comprises on a recess wall of a liquid discharge hole formation member attached to the first opening, a recess which becomes dent on the first opening side and protrudes to a center axis side of the nozzle insertion hole from the first opening side, and is continuous to the second opening, and has a liquid discharge hole for a liquid flowing from the nozzle insertion passage to the first opening. A liquid discharge valve having a rotary axis and a valve body are held to the recess wall to open and close the liquid discharge hole by rotation of the valve body around a rotary axis as a base point, on the recess.SELECTED DRAWING: Figure 3

    【課題】燃料タンクの開閉装置の排液性を確保した上で、アウターボディーを装置外側になるべく突出させないようにする。【解決手段】ノズル挿入通路を取り囲むハウジングに、ノズル挿入通路を大気開放する第1開口を有し、ハウジングが組み込まれるカバー本体に、ノズル挿入口と、第1開口と対向する大気開放の第2開口を有する。これに加え、ハウジングに装着された排液機構は、第1開口に装着された排液口形成部材の凹所壁に、第1開口側からノズル挿入口の中心軸側に突出して第1開口側で窪んだ凹所を第2開口に連続して形成し、ノズル挿入通路から第1開口に向けて流れる液体の排液口を有する。そして、回動軸と弁本体とを有する排液弁は、凹所において、回動軸を基点とした弁本体の回動により排液口を開閉するよう凹所壁に対して保持されている。【選択図】図3
