Abstract
A hermetically sealed fuel tank apparatus includes a pressure-resistant fuel tank for storing a fuel therein, the pressure-resistant fuel tank being capable of holding an internal pressure equal to or higher than the atmospheric pressure, a fuel vapor inlet pipe for introducing a fuel vapor produced in the pressure-resistant fuel tank, a canister contained in the pressure-resistant fuel tank and connected to the fuel vapor inlet pipe for adsorbing the fuel vapor, a drain passage through which the canister communicates with external air, and a shutoff valve connected to the drain passage and normally closed to hermetically seal the pressure-resistant fuel tank.
