PROBLEM TO BE SOLVED: To provide an oil supply port structure of a filler tube, capable of achieving the reduction of mold cost by molding an oil supply gun guide member by using a common metal mold for both gasoline fuel oil supply and light oil fuel.SOLUTION: A gun guide part 10 for gasoline fuel oil supply is constructed by forming a filler tube 2 side tip part of an oil supply gun guide member 6 in a taper cylindrical part 8 in a tapered shape. An oil supply gun guide part 14 for light oil fuel supply is formed by being provided with a plurality of groove parts 12 on the side face wall of the taper cylindrical part 8, and constituted of an aperture Dlarger diameter than an aperture Dof the gun guide part 10 for gasoline fuel oil supply by pushing and widening the taper cylindrical part 8, using the groove parts 12.

    【課題】給油ガンガイド部材をガソリン燃料給油用と軽油燃料用とを両者共用の金型を用いることにより成形することで、金型費用の低減を達成することができるフィラーチューブの給油口構造を提供する。【解決手段】給油ガンガイド部材6のフィラーチューブ2側先端部を先細り状のテーパー筒部8に形成することによってガソリン燃料供給用ガンガイド部10に構成すると共に、テーパー筒部8の側面壁に複数条の溝部12を設けて、溝部12を利用してテーパー筒部8を押し広げることによってガソリン燃料供給用ガンガイド部10の口径D1より大径の口径D2で構成する軽油燃料供給用給油ガンガイド部14を形成できるように構成した。【選択図】図3
