Abstract
This fueling device comprises a filler neck formed by stacking a first resin layer made of a first resin and a second resin layer made of a second resin that is harder than the first resin, such that the second resin layer is provided on an inner side of the first resin layer; and a mounting member mounted to a fuel injection opening side of the filler neck from outside. The first resin layer has a higher impact resistance than the second resin layer. The second resin layer has a higher fuel permeation resistance than the first resin layer. The filler neck includes an engagement element that is provided on the fuel injection opening side of the filler neck and is extended radially outward from the second resin layer to pass through the first resin layer. The mounting member is engaged with the engagement element to be mounted to the filler neck.
