Beschreibung
Zusammenfassung:	An electrically-operated actuator rotates a valve toward its closing side or opening side. A valve urging part urges the valve from a fully-closed position toward the opening side. An ACT control part controls the electrically-operated actuator to drive. A set load of the valve urging part is smaller than a set load that is capable of returning the valve from a fully-closed position to an intermediate position only by urging force of the valve urging part. When a position of the valve at time of turning off an IG switch for stopping operation of an internal-combustion engine is on the closing side of the intermediate position, the ACT control part shifts the valve to the intermediate position by the electrically-operated actuator after the IG switch is turned off.
