Abstract

A power transmission system for a snowmobile reduces the weight thereof, and allows a streamlined body to be obtained. A drive side pulley of a V-belt transmission is mounted on a right end of a crankshaft of an engine. A gear box is disposed on the right side of a driven side pulley of the V-belt transmission at a position near the driven side pulley. The driven side pulley is fastened to an input shaft. Thus, the V-belt transmission and gear box are disposed on the same right side of the engine, so that the connecting shaft for connecting the V-belt transmission to the gear box is shortened and the weight thereof is reduced. Further, the V-belt transmission and the engine are disposed between a pair of right and left main frames, and the gear box is disposed outside of the right main frame, to thereby shorten a distance between the right and left main frames.
