To provide a vehicle fuel pipe structure for cooling a fuel pipe with cooling air passing through a radiator fan to improve the operating performance of an engine even when an inclined face rising toward the rear side of a vehicle is formed on the upper face of a transmission case.

In the vehicle fuel pipe structure, an extending portion extending to a position higher than the top of the inclined face in the vertical direction is formed on a portion of a metal fuel pipe out of the fuel pipe, a canister is arranged over the inclined face at a predetermined space, and a space portion facing the extending portion is formed between the canister and the inclined face. Thus, cooling air passing through the radiator fan is guided through the space portion into the extending portion.
