Abstract
There is provided a fueling device comprising a filler neck that forms a fuel path region on a filler port side in a fuel path from a filler port for a fuel to a fuel tank; and a mounting member that is mounted to the filler port side of the filler neck to receive a fuel gun. The filler neck includes an enlarged-diameter circumferential wall portion that is provided in upstream of a position where a leading end of the fuel gun inserted from the mounting member at the filler port is placed, and is enlarged outward in a radial direction relative to an opening-side path circumferential wall which is a fuel path circumferential wall on the filler port side, in order to expand a volume of the fuel path. This configuration causes the fuel to flow into a space formed by this enlarged-diameter circumferential wall portion and thereby reduces or suppresses the occurrence of the fuel overflow from the opening of the filler neck after a stop of fueling.
