PROBLEM TO BE SOLVED: To provide a fuel tank opening and closing device which reduces dust entering into a fuel passage, where liquid fuel flows therein, from an outside.SOLUTION: A fuel opening and closing device (100) comprises: a fuel passage formulation section (20) which forms a fuel passage (100P) carrying supplied liquid fuel to a fuel tank; an insertion side opening and closing mechanism (10) which opens and closes the fuel passage (100P); a tank side opening and closing mechanism (30) which is arranged closer to a side of the fuel tank than the insertion side opening and closing mechanism (10) and opens and closes the fuel passage (100P); a waste liquid passage (40P) which communicates a portion of the fuel passage (100P) between the insertion side opening and closing mechanism (10) and the tank side opening and closing mechanism (30) with an outside of the opening and closing device (100); and an on-off valve (50) which opens and closes the waste liquid passage (40P) and communicates the fuel passage with the outside of the opening and closing device (100).SELECTED DRAWING: Figure 3

    【課題】燃料タンクの開閉装置において、液体燃料が通過する燃料通路に外部から侵入する塵などを低減させる。【解決手段】燃料タンクの開閉装置(100)は、供給された液体燃料を燃料タンクへと導く燃料通路(100P)を形成する燃料通路形成部(20)と;燃料通路(100P)を開閉する挿入側開閉機構(10)と;挿入側開閉機構(10)よりも燃料タンク側に配置され、燃料通路(100P)を開閉するタンク側開閉機構(30)と;燃料通路(100P)における挿入側開閉機構(10)とタンク側開閉機構(30)との間と、開閉装置(100)の外部と、を連通する排液路(40P)と;排液路(40P)を開閉し、前記開閉装置(100)の外部側へと開弁する開閉弁(50)と、を備える。【選択図】図3
