徴とする過給圧コントロール装置。 A bypass path that bypasses engine exhaust gas to the exhaust turbine outlet side without sending it to the exhaust turbine; a waste gate valve that opens and closes the bypass path; and the waste gate valve is driven to open and close by the internal pressure of the intake pipe downstream of the compressor. In the boost pressure control device for a turbocharger provided with a wastegate control actuator, the wastegate control actuator is communicated with the intake pipe on the downstream side of the throttle valve located downstream of the compressor. A supercharging pressure control device, characterized in that it is operated by the internal pressure of the intake pipe downstream of the throttle valve.
