ABSTRACT:
In an auxiliary-driving system in an engine, a crank pulley, a first auxiliary pulley and an idler pulley having a tensioner function are disposed in a triangular configuration with the idler pulley located in an uppermost position; and a second auxiliary pulley is disposed in a space surrounded by these pulleys. An endless transmitting belt is reeved around the pulleys. An inner surface of the transmitting belt is reeved around the first auxiliary pulley; and an outer surface of the transmitting belt is reeved around the second auxiliary pulley. Thus, the adjustment of the tension of the transmitting belt and other maintenance are facilitated, the transmitting efficiency of the transmitting belt can be enhanced, and compactness of the auxiliary-driving system itself and improvement in mileage can be achieved.
