ABSTRACT:
A toroidal-type continuously variable transmission, has: first and second disks; a plurality of trunnions; a plurality of displacement shafts respectively supported on associated trunnions; a plurality of power rollers respectively interposed between the first and second disks; and, a plurality of thrust bearings respectively interposed between the power rollers and trunnions, each of the thrust bearings including an outer ring, an inner raceway formed in the outer end face of the power roller, a plurality of rolling elements, and a circular-ring-shaped retainer, wherein, in case where the density of a retainer material constituting the retainer is ρd, the elastic modulus of the retainer material is Ed, the density of rolling element materials is ρcand the elastic modulus of the rolling element materials is Ec,{(ρd·Ed)/(ρc·Ec)}12≤0.6is satisfied.
