When a lid switch is operated and fueling control is started, an ECU of the evaporated fuel treatment device opens a sealing valve to release the tank internal pressure and closes the sealing valve after release of the tank internal pressure. Also, after the sealing valve is closed during the fueling control: the ECU opens the sealing valve to release the tank internal pressure and closes the sealing valve after release of the tank internal pressure, under the condition that the tank internal pressure is not less than a predetermined value and furthermore a rising speed of the tank internal pressure is less than a predetermined value; and the ECU maintains the closed state of the sealing valve, under the condition that the tank internal pressure is not less than the predetermined value and furthermore the rising speed of the tank internal pressure is not less than the predetermined value.
