PURPOSE:To reduce driving loss of an engine accessory by interlocking two driving systems with a crank shaft, and interposing an on-off clutch between one of said driving systems and a driving shaft and a one-way clutch between the other of said driving systems and the driving shaft. CONSTITUTION:A timing belt driving system T1 and a V belt driving system T2 are interlocked with a crank shaft 1 and these driving systems are interlocked with the driving shaft 12 of a constantly driven engine accessory P with different rotating ratios. An on-off clutch C1 is interposed between the driving system T1 and the driving shaft 12, while a one-way clutch C2 interposed between the driving system T2 and the driving shaft 12. Hereby, the engine accessory P can be driven with rotating ratios in two steps with respect to an engine. Accordingly, it is possible to reduce the driving loss of the engine accessory to improve engine performance as a whole. |
