置。An intake negative pressure control device for an internal combustion engine, which includes a turbocharger that pressurizes intake air by exhaust gas, a bypass passage that bypasses a throttle valve, and a negative pressure control valve that is interposed in the bypass passage and opens when the engine decelerates. A shutter valve for controlling the opening of the bypass passage is provided in the passage in series with the negative pressure control valve, and a pressure switch is provided for detecting the pressure in the intake pipe upstream of the throttle valve, and when the pressure in the intake pipe is above a predetermined value, the shutter is activated. An intake negative pressure control device for an internal combustion engine, characterized in that the opening of the bypass passage is narrowed by a valve.
