Abstract: A frictional type continuously variable transmission having a continuously variable transmission unit with a planetary gear unit attached thereto to increase the speed ratio as a whole while not increasing the size of the entire device. This transmission is composed of the continuously variable transmission, a planetary gear unit and an impeller unit. The planetary gear unit has a drive shaft, a carrier fixed to the drive shaft, a plurality of planetary gears supported on the carrier, and an internal gear meshing with the planetary gears. The continuously variable transmission unit has an input shaft to which is fixed a sun gear meshing with the planetary gear. With this arrangement, the impeller can be rotated at a high speed even if the speed ratio of the continuously variable transmission unit is low. The transmission unit also has a pressing mechanism at the input shaft end. Thus, it is possible to manufacture the three units separately and assemble them together.
