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 U 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 U comprises a pair of flap bodies 18 and 18 and biasing means 19 that position the flap bodies 18 at closing positions by bias. Each of the pair of flap bodies 18 and 18 comprises a rotation/assembly portion as a center of the rotation and a contact portion 18b to the other flap body 18, where a surface portion of the flap body is pressed against a port edge part 21a of a through port 21 of the oil supply nozzle and the contact portion 18b is pressed against the contact portion 18b of the other flap body 18, by the bias.
【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Uを備えてなる開閉装置である。前記閉鎖部材Uは、一対のフラップ体18,18と、各フラップ体18を付勢により閉じ位置に位置づける付勢手段19とを備えている。前記一対のフラップ体18,18はそれぞれ、前記回動の中心となる回動組み付け部と、他方のフラップ体18に対する当接部18bとを備えると共に、前記付勢によりその表面部を前記給油ノズルの通過口21の口縁部21aに押しつけ且つ前記当接部18bを他方のフラップ体18の前記当接部18bに押しつけるようになっている。【選択図】図5
