A fuel filling port structure of a fuel tank is provided in which a lid housed in the port structure is biased towards a closed position when a fuel supply nozzle is not inserted, and moved to an open position when the fuel supply nozzle is inserted. Lid locking mechanisms are disposed in the port structure which lock the lid in the closed position or unlock the lid so as to be movable to the open position corresponding to the insertion of the fuel supply nozzle.
