To provide an opening/closing device of a fuel tank, in which movability of a liquid discharge valve for opening and closing a liquid discharge path of the device is secured.SOLUTION: A housing surrounding a nozzle insertion passage is provided with a first opening through which the nozzle insertion passage is opened to the atmosphere, and a cover main body to which the housing is assembled is provided with a nozzle insertion port and a second opening, opposing to the first opening, through which the passage is opened to the atmosphere. Further, a liquid discharging mechanism mounted on the housing comprises a liquid discharge port on the liquid discharge passage 48d extending from the first opening to the second opening so that the port leads to the first opening, which makes a liquid discharge valve 47 open and close the liquid discharge port. When the liquid discharge valve opens the liquid discharge port by turning a valve main body with a turning shaft as a base point, an opening restricting part contacts a portion of an upper surface of the valve main body, so as to restrict the turning of the valve main body.SELECTED DRAWING: Figure 10
【課題】燃料タンクの開閉装置の排液路を開閉する排液弁の可動性を確保する。【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開口から第2開口に至るまでの排液通路48dに排液口を第1開口に連続させて備え、排液口を排液弁47により開閉する。排液弁が回動軸を基点とした弁本体の回動により排液口を開放する際、開弁規制部が弁本体の弁本体上面の一部に当接することで、弁本体の回動が規制される。【選択図】図10
