When a failure occurs in the electrical system of a car while travelling at low speed, the toroidal continuous variable transmission fixes the transmission ratio to a value on the speed-decrease side, so that the car can start even when the car stops on a slope or it is heavily loaded. Further, when one spool valve (30) is at the neutral position and if one of the trunnions (4) supporting the power rollers (2) should receive a force due to torque variations in the input disk (3), the other trunnion (4) is not affected at all and not displaced. <IMAGE> |
