Abstract
An automatic centrifugal clutch is arranged at the rear of an engine of a motorcycle, and a belt type continuously variable transmission and a gear type speed reduction device are arranged on opposite sides of the clutch whereby a space at the rear of the engine is effectively utilized, and a space for installing a kick starter is secured externally of the belt type continuously variable transmission. An output shaft of a reduction device and an intermediate shaft of the reduction device are arranged on opposite sides of a plane extending so as to include axes of a crankshaft and an input shaft whereby the longitudinal length of a power transmission device is shortened. An opening of a cooling air discharge passage is provided to face the automatic centrifugal clutch at the front end of the reduction device whereby the automatic centrifugal clutch can be effectively cooled while effectively utilizing the space. Two mating surfaces formed in the case means are offset from each other, whereby the space within the case means can be effectively utilized. Furthermore, a reed valve and a starter motor are arranged with the crankshaft interposed therebetween on a crank case whereby there is secured a space for efficiently arranging an intake system leading to the reed valve.
