<p>A control system for a toroidal type continuously variable transmission which incorporates a toroidal continuously variable gear mechanism (20,30) comprising an input (21) and an output (22) toroidal disk and a roller (23) disposed between the input and output toroidal disks and continuously varies a gear ratio according to inclinations of the roller actuates a stepping motor, when a specific driving condition which causes the continuously variable transmission to switch between a first and a second control mode and directional reversal of torque transmission through the toroidal continuously variable gear mechanism occurs with a result of causing a shift of the roller from one side to another side of the neutral position, to operate a double-slider shift valve (220,230) to cause the shift of the roller in advance. <IMAGE></p> |
