PROBLEM TO BE SOLVED: To provide a refueling device capable of shortening the overall length of a refueling port and improving the degree of freedom of layout of filler piping.SOLUTION: A filler tube 30 comprises: a fitting cylinder part 31 which is fitted to an outer peripheral surface of a refueling port 20 on the side of an exit 52; a tapered cylinder part 33 which is formed to a large diameter on the side of the fitting cylinder part 31 and also formed to a small diameter on the opposite side from the fitting cylinder part 31; and a small-diameter cylinder part 34 which is connected to the small-diameter side of the tapered cylinder part 33, and formed to a smaller diameter than the fitting cylinder part 31 and also formed to have a predetermined inner diameter D4 set based upon a fuel flow condition from the refueling port 20 to a fuel tank 10. An inner diameter D2 of an exit 52 of the refueling port 20 is larger than the predetermined inner diameter D4 of the small-diameter cylinder part 34 of the filler tube 30.SELECTED DRAWING: Figure 3
【課題】給油口の全長を短くすると共に、フィラー配管のレイアウトの自由度を向上させることができる給油装置を提供する。【解決手段】フィラーチューブ30は、給油口20の出口52側の外周面に嵌合される嵌合筒部31と、嵌合筒部31側が大径に形成され、かつ、嵌合筒部31と反対側が小径に形成されるテーパ筒部33と、テーパ筒部33の小径側に接続され、嵌合筒部31より小径に形成され、給油口20から燃料タンク10への燃料流通条件に基づいて設定された所定内径D4に形成される小径筒部34とを備える。給油口20の出口52の内径D2は、フィラーチューブ30の小径筒部34の所定内径D4より大きく形成される。【選択図】図3
