A toroidal CVT is comprised of an input disc, an output disc coaxial with the input disc, and a power roller disposed on opposite surfaces of the input and output disc to transmit power from the input disc to the output disc. Dimensions and relationship of the input and output discs and the power roller are determined such that a spin S generated at each of a first contact point between the input disc and the power roller and a second contact point between the output disc and the power roller takes positive value throughout a transmission ratio range of the toroidal CVT. When S = äsin &thetas; . sin phi - (1 + k - cos phi ) . cos &thetas;ü / sin &thetas;, values &thetas;, phi and k are determined so that S is greater than or equal to zero. <IMAGE> |
