A fuel-filling aperture opening-closing device, which opens two valve bodies by inserting a fuel-filling nozzle, facilitates an insertion of the fuel-filling nozzle, and reliably opens the two valve bodies by the insertion of the fuel-filling nozzle. The fuel-filling aperture opening-closing device provided in one end of a filler pipe communicating with a fuel tank includes a tube member internally forming a pathway, and connected to one end of the filler pipe; a first valve device provided inside the pathway, and opening a valve by being pressed by the fuel-filling nozzle inserted from an outer end side of the pathway; and a second valve device provided on an outer end side more than the first valve device inside the pathway, and opening a valve by being pressed by the fuel-filling nozzle inserted from the outer end side of the pathway so as to allow the fuel-filling nozzle to pass through. The first valve device opens by a load smaller than that of the second valve device. |
