PURPOSE: A continuously variable transmission is provided to improve endurance by operating friction wheels without slip with little frictional force, and to increase power transmission efficiency by reducing power loss with simple structure. CONSTITUTION: An input transmission gear is arranged between an input gear(20) and intermediate gears(22,23), and friction wheels(24,24a) are combined with intermediate gears. Driving force of friction wheels is applied vertically to outer friction wheels(27,27a), and rotational force of friction wheels is transmitted to an output gear through the intermediate gear and an output transmission gear(25). Shifting is performed by varying the circumference ratio of friction wheels and outer friction wheels with adjusting plates(35,35a). Endurance is improved with transmitting power by using friction wheels and gears.
