ABSTRACT:
Herein disclosed is a friction roller type continuously variable transmission which is compact in size. The transmission comprises a casing, input and output cone discs facing each other, two friction rollers each being operatively disposed between the input and output cone discs, two roller supporting members for rotatably supporting the friction rollers, first and second bearing supporting members each having opposed ends which are connected to one ends of the roller supporting members through respective bearings, first and second link posts supporting middle portions of the first and second bearing supporting members respectively, and a control valve body installing therein various control valves for controlling operation of the transmission, the control valve body being secured to the casing. In order to reduce the size of the entire construction of the transmission, the first link post is fixed to the casing, while the second link post is fixed to the control valve body.
