A sealing device for the fuel supply port of a fuel tank for use in vehicles includes a nozzle seal made of a rubber-like elastic material. The nozzle seal is provided in an annular groove formed in an inner peripheral surface of a fuel supply port guide in such a manner as to be movable in a radial direction. The inner peripheral portion of the nozzle seal can make contact with a fuel supply nozzle with an interference provided therebetween. A seal is provided on an outer peripheral or side surface of the nozzle seal to seal a gap in said annular groove. A reinforcing ring is provided on an outer peripheral portion of the nozzle seal. The reinforcing ring has axial and radial portions. The radial portion of the reinforcing ring is located adjacent to the fuel supply port guide on a side of the annular groove adjacent to the tank.
