A supercharger is applied to the combination of an engine, an air intake passage through which air is conducted to the engine, and an auxiliary device connectable to the engine to be driven by the engine. The supercharger includes a compressor disposed in the air intake passage to compress air conducted to the engine. The compressor is connectable to the engine to be driven by the engine. A sensor is provided to sense whether or not the power output required of the engine is higher than a predetermined level. A first clutch responsive to the sensor disconnects the compressor from the engine when the power output required of the engine is not higher than the predetermined level. A second clutch responsive to the sensor disconnects the auxiliary device from the engine when the power output required of the engine is higher than the predetermined level. |
