Abstract
Plural auxiliaries are independently driven by a belt ot suppress an increase in the number of parts and simplify the structure. A cam shaft has first and second driving pulleys disposed in parallel to each other. A first auxiliary having a smaller load against the engine is movably mounted to the engine and it has a first following pulley mounted to its operating shaft which is coaxially and rotatably mounted with an idle pulley. On the other hand, a second auxiliary having a larger load against the engine is fixed to the engine. To the engine is movably mounted a tension pulley. A first belt for driving the first auxiliary is wound around the first following pulley, the first driving pulley and a tension pulley, while a second belt for driving the second auxiliary is wound around the second driving pulley and the idle pulley. The tension of the first belt is adjusted by transferring the tension pulley, while the tension of the second belt is adjusted by transferring the first auxiliary.
