A resin filler tube includes: a tubular body; a flange having a diameter greater than an outer diameter of the tubular body, a thickness greater than a thickness of the tubular body, and a predetermined width in an axial direction, and having a first axial end face forming a weld surface to be welded to an outer circumferential edge of an opening hole of a fuel tank; and a base-end-side reverse tapered portion which connects between an end of the tubular body on the fuel tank side and an end of an outer circumferential surface of the flange on a side opposite to the fuel tank side, and which is reversely tapered so as to increase a diameter toward the flange. The base-end-side reverse tapered portion has an inner diameter that is not less than an inner diameter of the tubular body over an entire range in the axial direction.

Resin filler tube and manufacturing method for the same

A fuel filler structure includes a base member, a shutter member, a seal part, and an opening part. The base member includes a fuel filler port and a fuel filler port outer circumferential part which is provided outward further than the fuel filler port. In the shutter member, an opening-closing valve is supported movable to a closed position and an open position. The seal part is arranged between the fuel filler port outer circumferential part and the opening-closing valve when the opening-closing valve is located at the closed position. The opening part connects together an outer surface and an inner surface of the fuel filler port outer circumferential part, and a second opening end of the opening part is arranged at a position that overlaps the opening-closing valve when the opening-closing valve is located at the closed position.
