PURPOSE: A device for preventing the leakage of evaporated gas of fuel is provided to prevent the leakage of the evaporated gas of fuel inside a fuel tank though a fuel cap is opened for injecting fuel. CONSTITUTION: A rotating disk valve(4) is rotated by a rotating shaft(3) to open and close a fuel inlet pipe(1) by inserting a fuel injecting gun(8). A return spring accumulates elastic force by transforming through the rotating shaft when the fuel injecting gun is inserted by pushing the rotating disk valve. The rotating disk valve closes the fuel inlet pipe though a fuel cap is opened to inject fuel. Thereby, the leakage of evaporated gas of fuel is prevented.
