置。An exhaust throttle valve control device for an engine, which includes an exhaust throttle valve in an exhaust passage and a pressure actuator for driving the exhaust throttle valve, and controls the exhaust throttle valve in the closing direction in a predetermined operating state. In the above, the exhaust throttle valve is a normally open valve, a basic pressure supply means is provided to apply pressure other than the intake negative pressure to the pressure type actuator to give the basic opening degree to the exhaust throttle valve, and the pressure type 1. An exhaust throttle valve control device for a vehicle engine, characterized in that the actuator is configured to apply intake negative pressure to an actuator, and to control the exhaust throttle valve from a basic opening degree to an opening direction as the intake negative pressure increases.
