Abstract

An internal combustion engine includes a continuously variable transmission chamber formed of a crank case and a cover member connected to the crank case to permit the use of oil different between the internal combustion engine and the continuously variable transmission. Thereafter, a sufficient amount of each oil is ensured to not reduce the lowest road clearance. A division wall divides an interior of an oil pan into an internal combustion engine side oil reservoir and a continuously variable transmission side oil reservoir that reserves oil for lubrication of a continuously variable transmission and for speed control thereof, and which is connected to a lower portion of a crank case. The continuously variable transmission side oil reservoir is formed in a width direction of the motorcycle wherein part of continuously variable transmission side oil reservoir expands more outwardly than a continuously variable transmission chamber.
