Abstract
When a vehicle comprising a toroidal continuously variable transmission is pulled or run under its own inertia when the engine has stopped, the rotation torque of the drive wheels varies a gyration angle of a power roller (44FR, 44FL, 44RR, 44RL) via an output disk (18, 20) in a direction so as to reduce a speed ratio. This decrease of speed ratio reduces starting performance when the vehicle is restarted by the engine. This invention suppresses the variation of gyration angle by a spring (100) which limits the displacement of a trunnion (46FR, 46FL, 46RR, 46RL) supporting the power roller (44FR, 44FL, 44RR, 44RL).
