ABSTRACT:
A toroidal-type continuously variable transmission has: an input shaft; an input side disk and an output side disk respectively disposed on the outer periphery of the input shaft, the input side disk including a first cam surface; and a loading cam device interposed between the input side and output side disks and comprising: a loading cam including a second cam surface and rotatable together with the input shaft; a plurality of rollers interposed rollably between the first cam surface and the second cam surface; and a retainer, the retainer including a retainer main body having a circular-shaped fitting hole, and inside-diameter side projecting portions disposed on a retainer main body for maintaining the attitude of the retainer main body, wherein inside diameters of portions of the fitting hole corresponding to the inside-diameter side projecting portions are larger than that of the remaining portions of the fitting hole.
