PROBLEM TO BE SOLVED: To make sealability at the time when an oil supply port is closed by an oil supply port opening/closing device further sure and superior.SOLUTION: An opening/closing device comprises a closing member La that is rotated to an opening position by introduction of an oil supply nozzle N so as to open an oil supply port. The closing member La comprises a flap body 10 comprising a ring-shaped seal member 101 and biasing means 11 that positions the flap body 10 at a closing position by bias. The seal member 101 comprises inner and outer seal portions 101 respectively; one of the inner and outer seal portions is set as a plate-shaped portion 101b that is pressure-welded to a protrusion 16 edging a port edge part of a through port 15 of the oil supply nozzle N, by the bias; and the other of the inner and outer seal portions 101 and 101 is constituted of an inner circumferential protruding portion 101c and an outer circumferential protruding portion 101d that are individually pressure-welded to the flap body 10.

    【課題】給油口開閉装置による給油口の閉鎖時のシール性を一層確実で優良なものにする。【解決手段】給油ノズルNの導入により開き位置に回動されて給油口を開放させる閉鎖部材Laを備えてなる開閉装置である。前記閉鎖部材Laは、リング状のシール部材101を備えたフラップ体10と、このフラップ体10を付勢により閉じ位置に位置づける付勢手段11とを備えている。前記シール部材101は、内外にそれぞれシール部分101を備えると共に、前記内外のシール部分101、101の一方を、前記給油ノズルNの通過口15の口縁部を縁取る突条16に前記付勢により圧接される板状部分101bとし、前記内外のシール部分101、101の他方を、前記フラップ体10にそれぞれ圧接される内側周回突部101cと外側周回突部101dとから構成してなる。【選択図】図10
