PROBLEM TO BE SOLVED: To miniaturize a gear ratio control device for toroidal type continuously variable transmission capable of restricting the self-vibration due to the vibration of an engine output shaft during the operation for stopping a vehicle while operating a brake pedal. SOLUTION: A shift control valve 200 for outputting the accelerating pressure PH and the decelerating pressure PL to a trunnion 35 is provided with a cam 400 and a lever 402 for performing the feedback of a displacement of the trunnion 35. When the trunnion 35 is displaced by the vibration of an engine output shaft, a spool 203 inside of the control valve 200 is moved by the cam 400 and the lever 402, and the control valve 200 outputs the accelerating pressure PH and the decelerating pressure PL for pushing and returning the displacement of the trunnion 35 to an acceleration chamber 38 and a deceleration chamber 39 of the trunnion 35. Since the spool 203 is arranged in the control valve 200, a gear ratio control device for toroidal type continuously variable transmission is miniaturized.
