Abstract: A continuous variable transmission is disclosed wherein the planetary gearset arranged downstream of the toroidal transmission mechanism is made simple in construction to reduce the overall axial length. To cope with this, a first planetary gearset arranged downstream of the toroidal transmission mechanism is comprised of a first carrier, a sun gear connected to an output disk, and a ring gear. The first carrier supports thereon a dual pinion having a first and second planet-gears.

The combined construction of the first and second planetary gearsets contributes to the reduction of the axial length in the gearing mechanism. The second clutch for high-range operation may hold the second ring gear to a stationary case.
