PROBLEM TO BE SOLVED: To provide a fuel evaporative gas exhaust suppression device which can suppress adsorption of fuel evaporative gas onto a canister after the end of a purge.SOLUTION: At the end of a high pressure purge (first purge control) (d-f) in which in a state in which a vapor solenoid valve is blockaded and also a tank blockade valve is open, a purge solenoid valve is open upon running of an engine, and a fuel evaporative gas inside a fuel tank is released into an inlet passage until an internal pressure of the fuel tank drops down to a second given pressure, a communicating path purge (second purge control) is performed (f-g) in which the tank blockade valve is closed, and the fuel evaporative gas inside vapor piping and purge piping is released into the inlet passage until turning into a second given integrated quantity (second given value) or more. |
