Abstract
A four-stroke-cycle engine of a vehicle such as snowmobile comprises a crank case, which is dividable into a plurality of crank case components having mating surfaces, through which the crank case is assembled, a crank shaft rotatably supported in the crank case at a portion between the mating surfaces of the crank case components, and a belt driven-type continuously variable transmission mechanism operatively connected to one end of the crank shaft through a clutch belt. The continuously variable transmission mechanism includes a drive shaft, and the clutch belt is stretched around the drive shaft and the crank shaft so that a tensioning direction of the clutch belt is shifted from a line passing the mating surfaces of the crank case components at a predetermined angle therebetween.
