    摘要: To make a continuously variable transmission small and to be able to freely set a transmission ratio of a driving force transmitted from an engine to a continuously variable transmission. A continuously variable transmission for carrying out gear changes by a rotary drive member and a driven rotary member supported so as to be freely rotatable at a main transmission shaft coming into contact with variable speed rotary members supported at gears and so as to be freely rotatable is housed within a transmission chamber partitioned from a crank chamber and enclosing lubricating oil. The driving force of the crank shaft of the engine is inputted to a driven gear provided at the main transmission shaft that passes through a cover member of the transmission chamber and protrudes to the inside of the crank chamber. By providing the driven gear outside of the transmission chamber, a situation where the dimensions of the continuously variable transmission T are made large due to the driven gear can be prevented and the transmission chamber can be made small. Further, the transmission ratio of the drive force transmitted to the continuously variable transmission T can be freely set just by changing the external diameter of the driven gear.
