ABSTRACT:
In an inner structure of a filler neck of a fuel filler tube, a nozzle support section for supporting a nozzle of a fuel filling gun at a gas station includes a pipe member having an inner diameter substantially equal to the outer diameter of the nozzle, and the nozzle is inserted in the pipe member when fueling. Fuel emitted from the nozzle is directed through the pipe member to an outlet end (distal end) of the nozzle support section, at which it starts flowing along an intermediate bent section of the filler tube. Thus, even when the fuel filling gun is not sufficiently inserted in the filler neck, i.e. inserted short of a standard inserted amount, the fuel is allowed to properly jet out in the bent section just as when the fuel filling gun is sufficiently inserted in the filler neck up to the standard inserted amount.
