A toroidal-type continuously variable transmission has a casing; an input disk and an output disk rotatably supported concentrically with each other; a plurality of power rollers each held between the input and output disks; a plurality of trunnions disposed at position twisted with respect to a center axis; a drive device for shifting the trunnions in the axial directions or the pivot shafts; a pair of yokes for supporting the pivot shafts of each of the trunnions so as to be swung and shifted in the axial direction thereof, the yokes being swingable according to the shifting movement of the associated trunnion; and, a pair of opposing members each disposed to be opposed to the associated yoke, wherein the yokes each includes projection portion contacted with the associated opposing member, the projection portion being the fulcrum of the swinging movements of the yokes.
