Fuel filler pipe

An inlet filler pipe comprises a pipe main body 41 having a fuel passage 40b for fueling fuel through an inlet 40a into a fuel tank, and a flange 42 formed on the pipe main body 41, for attachment to an outer wheel housing 30. A reinforcing element 70 comprising a plurality of first ribs 72a and second ribs 74a arranged so as to surround the pipe main body 41 is formed on the flange 42. The portion along the outer periphery of the pipe main body 41 between first ribs 72a and second ribs 74a serves as a fragile portion 76, ensuring breaks at a load over a predetermined level.
