PROBLEM TO BE SOLVED: To provide a filler pipe easy to fuel. SOLUTION: The filler pipe 1 with an upstream end in which a fueling gun 9 is inserted and with a downstream end communicating with the inside of a fuel tank 7 interconnects the upstream end and the downstream end through at least one of curved parts 220, 30. The filler pipe 1 has a small diameter part 22 arranged over the curved part 220 of the most upstream side of a tip end position of the inserted fueling gun 9, with an outer peripheral surface exposed to the outside of the pipe, and a large diameter part 3 extending a downstream side of the small diameter part 22 and having an inner peripheral diameter larger than the small diameter part 22. When an outer peripheral diameter of the tip end of the fueling gun 9 is 100%, the inner peripheral diameter of the small diameter part 22 is set above 100% to 135%. COPYRIGHT: (C)2005,JPO&NCIPI
