The filler neck is disposed to penetrate through the neck-penetrating opening into the inlet box, and has an outer peripheral surface provided with a flange. The flange has a flange-side axial engagement portion engaging with the box-side axial engagement portion to regulate axial movements of the filler neck, and a flange-side radial engagement portion engaging with the box-side radial engagement portion to regulate radial movements of the filler neck. The fuel supply apparatus can be assembled with ease, and can be manufactured at reduced cost.
