An evaporated fuel treatment device executes a pressure reducing control while monitoring inner pressure of a fuel tank, so that when the inner pressure of the fuel tank exceeds a predetermined value prior to fueling to the fuel tank, pressure reduction progresses within a range that the flow rate of a vapor passage does not exceed the boundary flow rate where the vapor passage is closed by a valve element of an ORVR valve, and also a valve opening speed of the closing valve is made higher as the inner pressure of the fuel tank becomes lower.
