PURPOSE: To simplify construction, by actuating a damper through a pressure difference between an intake manifold and delivery pipe.
CONSTITUTION: A supercharger 4, having an air introducing pipe 2 and delivery pipe 8 and forcibly feeding air, introduced from the air introducing pipe 2, to an intake manifold 5 of an internal-combustion engine, connected to the delivery pipe 8, and an electromagnetic clutch 10, selectively transmitting rotary output of the internal-combustion engine to a driving shaft of the supercharger 4, and the line of a bypass pipe 3, a communicating the air introducing pipe 2 to the delivery pipe 8, are provided. While a damper 1, selectively closing the delivery pipe 8 and the line of the bypass pipe 3 for the intake manifold 5 a difference of internal pressure between the intake manifold 5 and the delivery pipe 8 or the bypass pipe 3, is provided, and supercharge operation is performed only by on-off of the electromagnetic clutch, then construction can be simplified.
