<p>PROBLEM TO BE SOLVED: To provide a toroidal type continuously variable transmission which can reduce a stress at a spline tooth main part, in a disc having, in a penetration hole through which a shaft penetrates, a spline part which is splined to the shaft, and a spigot part which is spigot-fitted to the shaft.SOLUTION: In a toroidal type continuously variable transmission, a spline part 86 and a spigot part 87 are arranged on an inner peripheral face of a penetration hole 85 through which an input shaft of an input-side disc 2 penetrates in parallel with an axial direction of the penetration hole 85. The spline part 86 is splined to the input shaft. The spigot part 87 is spigot-fitted to the input shaft. A space forming part 88 which forms a space at the surrounding of the input shaft in a state of being penetrated with the input shaft is arranged between the spline part 86 and the spigot part 87.</p> |
