PURPOSE:To prevent fuel vapor from flowing out to the outside air by fixing a buffer member on a bottom wall surface inside a fuel tank, extending a fuel injection pipe to the vicinity of the buffer member, and arranging the fuel outflow port of the fuel injection pipe so as to face the buffer member. CONSTITUTION:The bottom wall surface 7 inside a fuel tank 1 is made flat, and a buffer member 8 made of a porous material such as a sponge, for example, is fixed on the inner bottom wall surface below a fuel injection pipe 2. The upper- end section of the fuel injection pipe 2 is protruded outward from the fuel tank 1 upward, and the lower-end section of the fuel injection pipe 2 is extended downward to the vicinity of the upper surface of the buffer member 8 in the fuel tank 1. The fuel outflow port 9 of the fuel injection pipe 2 is arranged so as to face the upper surface of the buffer member 8. |
