When the air throttle valve is actually used, after the air throttle valve executes an engine ECU command, the valve plate 11 is closed, high-pressure air of a vehicle air storage tank is led into an air channel in the air throttle valve through the additionally arranged electromagnetic valve 17, and an air inlet pipe of an engine is pressurized.
