摘要： A filler tube including a cylindrical body and flange is manufactured using a cylindrical workpiece. A material forms an outermost layer in the cylindrical body and flange of the cylindrical workpiece. Dividable molds move at a first speed upon adhering the cylindrical workpiece onto the site for forming the cylindrical body, thereby giving the cylindrical body a predetermined diametrical thickness; and then move at a second speed being slower than the first speed upon adhering the cylindrical workpiece onto the other site for forming the flange, thereby filling up the flange with the material and other materials for forming the flange over a diametrical range to be welded onto the fuel tank while making the diametrical thickness of the flange greater than that of the cylindrical body.

摘要： The disclosure provides a refueling port capable of simplifying a structure for restricting rotation of a nozzle guide with respect to a refueling port body. One of the refueling port body and the nozzle guide includes guide ribs formed between an inner peripheral surface of a body cylinder portion and an outer peripheral surface of a guide cylinder portion to sandwich a reflux port in the circumferential direction, and guiding fuel vapor flowing in from the reflux port in a direction toward a filler pipe connection port. The other one of the refueling port body and the nozzle guide includes a locking portion formed between the inner peripheral surface of the body cylinder portion and the outer peripheral surface of the guide cylinder portion, and locked in both directions in the circumferential direction to the guide ribs to restrict relative rotation between the refueling port body and the nozzle guide.

摘要： A manufacturing process for filler tube includes: a workpiece arrangement step of arranging a workpiece onto an outer peripheral mold not only to axially lock a to-be-locked portion with respect to a locking portion but also so as to make the outer peripheral mold, which is set at a predetermined temperature, support a cylinder-shaped body of the workpiece on the outer peripheral face; and a flare-molding step of flare molding a flange by inserting an inner peripheral mold, which is set at a higher temperature than the predetermined temperature of the outer peripheral mold, into a to-be-molded portion on the inner peripheral side, and by relatively moving the outer peripheral mold and the inner peripheral mold in the axial direction to make a counter-welding-face forming portion and a welding-face forming portion clamp the to-be-molded portion between them in the axial direction.

摘要： A filler tube, which is capable of satisfying required functions suitably in compliance with the bellows and non-bellows cylindrical base while securing weld strength and fuel-permeation resistance property in the weld face, is provided. A filler tube includes a non-bellows cylindrical base with a total thickness of from 2 to 4 mm, a bellows with a total thickness of from 0.5 to 3 mm, and a flange having a total thickness of from 3.5 to 5 mm, and including an end face to be welded to a fuel tank. The non-bellows cylindrical base, the bellows, and the flange include inner layers formed so as to have a thickness accounting for from 40 to 60% of the total thicknesses, and formed of high-density polyethylene (or HDPE) serving as the major constituent, intermediate layers exhibiting fuel-permeation resistance property, and outer layers protecting the intermediate layers.

摘要： A fuel filler port includes a resin fuel filler port main body formed tubular and having an interlock part on an outer circumferential surface thereof; an inlet metal fitting at least having an outer tube part formed tubular, positioned and disposed in the fuel filler port main body, and disposed to face the outer circumferential surface of the fuel filler port main body in a radial direction; and an earth metal fitting formed in a plate shape and interlocked with the interlock part. The earth metal fitting includes a tip bent part disposed between the outer circumferential surface of the fuel filler port main body and an inner circumferential surface of the outer tube part in the radial direction and disposed while having a biasing force in the radial direction with respect to the inner circumferential surface of the outer tube part.
