Abstract
A fueling device includes a fuel passage-forming member and a flap valve mechanism. The flap valve mechanism includes an opening-forming member attached to one end of the fuel passage-forming member and an opening-closing mechanism to open and close a filler inlet of the opening-forming member. The fuel passage-forming member includes a pipe body containing a resin inner layer in a pipe shape made of a first resin material and a resin outer made of a second resin material, and a welding end formed on an opening end of the pipe body. The opening-forming member includes a cover member that covers the opening end of the pipe body and a welded end formed on an opening end of the cover member and welded to the welding end. The cover member is made of a third resin material welded to either one of the first resin material and the second resin material.
