ABSTRACT:
In a continuously variable traction roller transmission, a combination of a precess cam and a generally L-shaped link is used for converting a rotational movement of a traction roller supporting member to an axial movement of a spool of a speed change control valve. The cam surface of the precess cam is convexed to achieve an optimum characteristic of speed change ratio.
