Provided is a single-cavity toroidal continuously variable transmission capable of suppressing gyro slippage and achieving mitigation of bearing loss and a longer service life.;In the single-cavity toroidal continuously variable transmission, a pitch circle diameter (PCD) of the output-side bearing 46 is smaller than that of the input-side bearing 43 and a ball diameter of the output-side bearing 46 is smaller than that of the input-side bearing 43. Therefore, centrifugal force acting on the ball of the output-side bearing on a speed increasing side with a low load can be suppressed. Therefore, gyro slippage can be suppressed and mitigation of bearing loss can be achieved. Furthermore, with a groove R ratio of the output-side bearing 46 smaller than that of the input-side bearing 43, a longer service life can be achieved even when the pitch circle diameter (PCD) and ball diameter of the output-side bearing 46 are smaller than those of the input-side bearing 43. |
