PROBLEM TO BE SOLVED: To reduce cost by common use of an installation tool, reduction in the necessary site area of a production field and reduction in the installation tool number, by installing a recirculation pipe of a comparatively thin diameter and a ventilation pipe of a comparatively thick diameter in a filler tube via connectors of the same shape.SOLUTION: The other end side of a filler tube 2 having a fuel suction port 3 on one end side, is connected to/installed in a tank body, and the one end side is opened in/connected to an upper space of the tank body, and when connecting and opening the other end side of a breather pipe 4 for deriving volatile fuel stayed in the upper space to a fuel injection port 3 to and on the filler tube 2 side, the other end side of the breather pipe 4 is connected to the filler tube 2 side via a connection connector 5, and the connection connector 5 is constituted so that a recirculation pipe of a comparatively thin diameter or a ventilation pipe 7 of a comparatively thick diameter for constituting the breather pipe 4, can be selectively and oil-tightly fitted and connected.SELECTED DRAWING: Figure 2

    【課題】比較的細径のリサーキュレーションパイプと比較的太径のベンチレーションパイプとを同一形状の接続具を介してフィラーチューブに装着可能にして装着治具の共用化、生産現場の必要敷地面積の縮小化及び装着治具数の減数によるコスト低減を図る。【解決手段】タンク本体に、一端側に燃料吸入口3を有するフィラーチューブ2の他端側を連結設置し、一端側がタンク本体の上部空間に開口連結して当該上部空間に滞留した揮発燃料を燃料注入口3に導出するブリザー管4の他端側をフィラーチューブ2側に連結開口する場合、ブリーザー管4の他端側を連結接続具5を介してフィラーチューブ2側に連結し、連結接続具5が、ブリーザー管4を構成する比較的細径のリサーキュレーションパイプ又は比較的太径のベンチレーションパイプ7を選択的に油密的に嵌合連結可能に構成した。【選択図】図2
