Abstract
Engine auxiliary unit driving equipment for transmitting an engine driving force from a crank pulley to a plurality of engine auxiliary units include an alternator and a driven poly-V pulley, provided at least in the alternator, has a plurality of grooves extending in a circumferential direction. A poly-V belt, which has a plurality of projections extending in a longitudinal direction to correspond to grooves of the poly-V pulley, bridges between a crank pulley and the poly-V pulley. The poly-V belt is substantially divided in an axial direction of the driven poly-V pulley into two pieces each having plural pieces of the projections. Accordingly, a tensile strength acting in a width direction of the poly-V belt is substantially divided midway between the divided poly-V belts to reduce cracking in the round poly-V belt, resulting in longer life of the poly-V belt.
