Abstract
A power transmission device for transmitting power of an internal combustion engine of a motorcycle. By improving the arrangement of a continuously variable transmission, a balancer shaft and a drive pulley and a driven pulley of the continuously variable transmission, a lateral width and longitudinal length of a power unit are decreased thus making the power unit more compact. A continuously variable transmission is arranged behind a crankshaft, and a balancer is arranged between the continuously variable transmission and the crankshaft in a state wherein the balancer does not overlap the continuously variable transmission. A drive force of the crankshaft is transmitted to a drive pulley shaft of the continuously variable transmission by way of a gear of a balancer shaft. The approximate center of the crankshaft, the balancer and the respective pulleys of the continuously variable transmission are arranged on a vertical plane of a vehicle body center line.
