PROBLEM TO BE SOLVED: To avoid imparting incongruity feeling to a driver without troublesome controlling by suppressing fluctuation of transmission gear ratio following fluctuation of torque. SOLUTION: A process cam 23 is supported and secured to an end of a rod 22 displaced with a trunnion for controlling a control valve for displacing the trunnion. An end of a linkage arm 24 is made to abut to a cam face 60 of the process cam 23 so as to switch the control valve based on the displacement of the trunnion. An abutting part of the cam face 60 abuts on the end of the linkage arm 24 is provided on a side of an input side disc 2A. An influence of elastic deformation of the trunnion can be suppressed low by these structure, and the purpose can be attained.
