A drive mechanism that drives this opening/closing valve mechanism, a rotation speed detection sensor that detects the engine rotation speed, a load detection sensor that detects the engine load, and output signals from the rotation speed detection sensor and the load detection sensor are input. The drive mechanism is controlled according to changes in the engine speed and engine load, and during low-load operation when the engine load is small, the opening area of the inlet is kept in a narrowed state and the flow flows into the turbine. It is characterized by comprising a controller that increases the flow velocity of exhaust gas and switches and controls the opening area of the inlet port 61 to a normal state in which it is opened larger than the throttle state when the engine load is greater than in the low-load operation.
