Abstract
A fuel filler pipe offering high anticorrosion performance and high fabrication accuracy is provided. Specifically, a tubular fuel filler pipe body 2 made of a plated steel sheet has a fuel filler port 2a at one end thereof, and is connected at the other end thereof to a fuel tank 10. A short cylindrical retainer 3 made of stainless steel is mounted into the fuel filler port 2a, and includes first and second tube members 5 and 6 each having both open ends. An inner circumferential surface of a portion of the first tube member 5 near an opening thereof at one end thereof includes an internal thread 5a threadedly connected to an external thread C1 of a fuel cap C. The second tube member 6 is inserted through an opening of the first tube member 5 at the other end thereof into the first tube member 5, and is joined to the first tube member 5 before the internal thread 5a by resistance spot welding Sw. One of the open ends of the second tube member 6 in a direction opposite to a direction of insertion of the second tube member 6 forms an insertion hole 6a through which a nozzle G1 of a fuel filler gun G is inserted.
