To provide an oil supply port closing device which enables a closing device of an oil supply port to be easily assembled to a fuel supply tube and makes the closing device less likely to be loosened after assembly, and to provide a closing device attachment structure.SOLUTION: A screw type oil supply port closing device is rotated along a circumferential direction of a fuel supply tube 5 to be fixed. The closing device has: a body 21 having a through hole and a valve seat disposed at an edge of the through hole; and a lid body which is rotatably supported by the body and biased to the valve seat. The body has an elastic part 212 which is displaced in a radial direction of the fuel supply tube to allow passage of a protruding part 52 when the protruding part of the fuel supply tube contacts therewith as the closing device is screwed into the fuel supply tube. An edge of the elastic part contacts with the protruding part of the fuel supply tube that has passed through the elastic part to prevent rotation of the closing device in a direction such that the closing device is loosened.SELECTED DRAWING: Figure 2
【課題】燃料給油管に対して給油口の閉鎖装置を簡単に組み付けることが可能であり、組み付け後においては緩みにくい給油口の閉鎖装置、及び閉鎖装置の取付構造を提供する。【解決手段】燃料給油管5の周方向に沿って回転させて固定する捩じ込み式の給油口の閉鎖装置であって、閉鎖装置は、貫通孔と当該貫通孔の縁に配される弁座を有する本体21と、本体に回動可能に支持されており、弁座に対して付勢された蓋体とを有しており、本体は、燃料給油管に対して捩じ込む操作に伴って燃料給油管の凸部52が接触したときに燃料給油管の半径方向に変位し凸部の通過を許す弾性部212を有しており、弾性部の縁は、弾性部を通過した燃料給油管の凸部と接触して閉鎖装置が緩む方向に回転することを防止する給油口の閉鎖装置である。【選択図】図2
