過給圧制御装置。 A bypass passage is provided that is connected in parallel to the turbocharger turbine installed in the exhaust passage of the engine body, and the opening/closing operation of the waste gate valve that opens and closes the bypass passage is controlled within the intake passage of the engine body. A supercharging pressure control device for an engine equipped with a main drive circuit that performs control based on the boost pressure of the supercharger, further comprising a supercharger rotational state detector that detects the rotational state of the supercharger; During normal operation, a predetermined rotational state lower than the allowable rotational state is set, and the rotational state of the supercharger is maintained at a rotational state lower than the set rotational state based on a detection signal from the rotational state detector. A controller that controls opening and closing of the waste gate valve by a main drive circuit, and sequentially opens the waste gate valve from a fully closed state to a fully open state when the rotation state of the supercharger reaches a set rotation state or more. A supercharging pressure control device for an engine, characterized in that:
