Abstract: The problem to be solved is to provide a fuel feeding device for vehicles that is stably secured to a vehicle body. In the fuel feeding device for vehicles having an inlet filler pipe 1 and a fixing member 4, a flexible element 5 is provided that relatively presses the inlet filler pipe 1 toward the fixing member 4. With the flexible element 5 causing the inlet filler pipe 1 and the fixing member 4 to make pressure contact with each other, there can hardly be any gap created between the inlet filler pipe 1 and the fixing member 4 irrespective of the difference in linear expansion coefficient between them.

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.
