  "textContent": "A controller of a toroidal continuously variable transmission comprises a position control unit which outputs a driving signal to a hydraulic actuator to control a roller position. The hydraulic actuator includes a biasing mechanism which forcibly keeps the roller position at a predetermined position in a case where the driving signal meets a predetermined condition. The position control unit is configured to perform a start-up control during start-up of the toroidal continuously variable transmission. During the start-up control, the position control unit is configured to output the driving signal to reciprocate a spool of the hydraulic actuator in a case where a temperature of hydraulic oil supplied to the hydraulic actuator is lower than a reference temperature, and output the driving signal which meets the predetermined condition in a case where the temperature of the hydraulic oil has become equal to or higher than the reference temperature thereafter.",
