An inter-flap space 36 between an outside flap 24 and an inside flap 44 of a filler pipe 16 is placed in communication with the inside of a fuel tank 14 using a communication pipe 62, and an open and close valve 64 is provided to the communication pipe 62. Further provided are a pressure reduction pump 82 that depressurizes the fuel tank 14, an internal tank pressure sensor 68 that detects an internal tank pressure of the fuel tank 14, and a controller that controls opening and closing of the open and close valve 64 and driving of the pressure reduction pump 82, and that determines an outside flap seal state of the outside flap 24 based on the internal tank pressure.
