PURPOSE:To be able to reduce the number of auxiliary machines driven by an engine by making a switch for driving the auxiliary machines except in the case of engine cranking so that a compressor, that is an auxiliary machine, can be driven by a starter motor. CONSTITUTION:When a switch 40 for driving auxiliary machines is on except in the case of engine cranking, electric current is sent to relay coils 42, 44 from a buttery 30, and a relay switch 39 is opened and a relay switch 45 is closed with a contact 43 for driving auxiliary machines turned on. Also, electric current is sent from the buttery 30 to a starter motor 37 through the contact 43, and said motor 37 is driven. Meanwhile, the relay switch 45 is closed, an electromagnetic clutch 47 is excited, and the starter motor 37 and a compressor 46 become conductive to each other. Therefore, the compressor serving as an auxiliary machine can driven by the starter motor 37. In this way, the number of auxiliary machines driven by an engine can be reduced by effective use of the starter motor 37. |
