PROBLEM TO BE SOLVED: To prevent deteriorations of air-fuel ratio control and exhaust emission by preventing direct purging of evaporated fuel inside a canister into an intake manifold of an engine, and to improve treating ability of the vaporized fuel. SOLUTION: Two canisters 8 and 8 A are provided, and suction means sucking the evaporated fuel inside a fuel tank 1 and lead out means A leading the evaporated fuel adsorbed and collected by adsorbing materials 11 of the canisters 8 and 8A leated outside the canisters 8 are provided in respective canisters. A liquefying means B is provided for liquefying the evaporated fuel lead out from both canisters 8 and 8A, and a means is provided for introducing the liquefied fuel inside the fuel tank 1 or a liquid fuel passage 3. A control part 34A is also provided for controlling, so that the other canister 8A carries out lead out operation of the evaporated fuel, when the one canister 8 is carrying out suction operation of the evaporated fuel.
