A fuel filler structure includes a cylindrical part having a fueling port and a connecting port; a first flap mechanism and a second flap mechanism that are disposed close to the fueling port and the connecting port of the cylindrical part, respectively, and when a nozzle is inserted through the fueling port, the respective flap mechanisms are pressed by the nozzle to open the fueling port and an opening on the connecting port side; a drain hole formed in the cylindrical part and allowing the inside of the cylindrical part to be communicated with the outside; and an opening and closing valve for opening and closing the drain hole. The opening and closing valve includes a valve mechanism that maintains a closed state of the drain hole through negative pressure suction by a volatile fuel suction mechanism attached to the nozzle.
