ジンの吸気装置。 An engine that has a control valve that opens and closes depending on the operating state of the engine, a negative pressure actuator that opens and closes the control valve against a certain urging force, and a negative pressure tank that serves as a drive source for the actuator. In the intake system, when negative pressure acts on the actuator from the negative pressure tank to move the control valve to the open or closed position, the control valve is moved to the open or closed position by resisting the urging force with a predetermined urging force. 1. An engine intake device, characterized in that it is provided with a valve position holding means for holding the valve position.
