A canister absorbs evaporated fuel produced in a fuel tank and supplies the absorbed evaporated fuel to an engine. A sealing valve is equipped between the fuel tank and the canister. A detection unit detects a state of a lid of the fuel tank. An intention estimation unit estimates existence of a refueling intention according to an activity of a user. A release time period estimation unit estimates a release time period, which is needed to release a pressure in the fuel tank, according to a state of a vehicle. A manipulation control unit opens the sealing valve when the lid is opened. The manipulation control unit opens the sealing valve, even in a case where the lid is closed, on estimation that the refueling intention exists, and on determination that the estimated release time period is greater than a predetermined time period.
