ABSTRACT:
In the toroidal type continuously variable transmission, durability of input-side disc 2 supported by ball spline is improved without reducing power to be transmitted. According to the present invention, spline groove is formed on the inner peripheral surface of a center hole to construct the ball spline. While one end of the spline groove reaches the back surface of the input-side disc, the other end does not reach the inner surface thereof. Since stress occurring in the disc can be mitigaled without reducing power to be transmitted, a continuously variable transmission with high performance and excellent durability can be obtained.
