The primary shift is made while moving along the inner surface of the friction wheel 7, and the primary shifted rotational force is input through the sun gear 24 of the planetary gear unit 26 and is shifted from the input shaft 1 at the same time. The non-rotational force is transmitted to the pinion gear 27 of the planetary gear unit 26 through the first clutch C1 so that the shift is made, while the primary shifted rotational force is transmitted through the second clutch C2. In the continuously variable transmission configured to be transmitted to the output shaft 3 as it is, a ring friction vehicle which is one end of the planetary roller 6 is elastically supported by the elastic means 21, and moves along the surface of the planetary roller 6. (7) the movement is detected and controlled by the position sensor 22 have. The continuously variable transmission of the present invention having such a structure has a high pressure maintained between the planetary roller 6 and the ring friction car 7 while the ring friction car 7 moves along the surface with the planetary roller 6. The planetary roller 6 prevents the phenomenon of moving along the longitudinal direction.
