A fuel-filling aperture open-closing device provided in a filler pipe communicated with a fuel tank includes a tube member forming a pathway and connected to one end of the filler pipe, and a valve body rotatably provided inside the pathway, blocking the pathway by an urging member, and opening the pathway when rotating to an inner end side of the pathway by being pressed by a fuel-filling nozzle inserted into the pathway. The tube member includes a discharge hole communicating an outer surface with an inner surface of the tube member in a portion in which an outer surface of a lateral circumferential portion thereof faces downward, and corresponding to a portion on the outer end side in a closed position of the valve body. The valve body includes a plurality of discharge grooves extending toward the discharge hole in a portion on the outer end side. |
