PROBLEM TO BE SOLVED: To reduce the number of control valves switched in adsorbing or purging fuel vapor in or from a fueling canister or a driving canister, and reduce the capacity of the fueling canister. SOLUTION: A solenoid valve 26 can connect the driving canister 20 to either of the fueling canister 16 and a bypass passage 36, and a control circuit 28 connects, during fueling, the fueling canister 16 and the driving canister 20, and during parking, the bypass passage 36 and the driving canister 20. During purging, the control circuit 28 controls the solenoid valve 26 according to data stored in advance in the control circuit 28, to thereby connect the bypass passage 36 and the driving canister 20 or connect the fueling canister 16 and the driving canister 20, properly during purging.
