摘要： A pivotal feedback line has at one end thereof a follower member that is slidably put on a work surface of a precess cam actuated by a trunnion of a toroidal type continuously variable transmission. A speed control valve has a spool. The spool is moved for feeding a hydraulic actuator of the transmission with a hydraulic pressure to control the trunnion. An electric actuator has an output member. A speed change link is arranged to which the other end of the pivotal feedback link, the spool of the speed control valve and the output member of the electric actuator are connected through first, second and third articulated members respectively. A spring member is connected with the pivotal feedback link at a position between the first articulated member and the follower member to bias the pivotal feedback link in a direction to press the follower member against the work surface of the precess cam so that the biasing force of the first biasing member does not affect the moment of rotation of the speed change link about the first articulated member.
