To restrict torque transmission at the time of turbulence on a non- stage transmission and to prevent gross slip.

This control device of the toroidal type non-stage transmission generates holding force to hold a rotating member 3 at a specified position against tangential force to use in accordance with transmission of torque by sandwiching the rotating member to mediate transmission of the torque between an input disc and an output disc between these discs, and it is furnished with holding force control means 25, 26 to control the holding force so as to move the rotating member 3 by the tangential force based on the torque in the case when the torque to work on the non-stage transmission is higher than a specified value.
