First Claim
1. A toroidal-type continuously variable transmission comprising:
- 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, in the outer surface thereof, a first cam surface formed as an uneven surface extending in the circumferential direction of the input side disk; and
a loading cam device interposed between the input side and output side disks and comprising;
a loading cam including, in one side surface thereof, a second cam surface formed as an uneven surface extending in the circumferential direction thereof and rotatable together with the input shaft;
a plurality of rollers interposed rollably between the first cam surface of the input side disk and the second cam surface of the loading cam; and
a retainer for supporting the rollers, the retainer including a retainer main body having a circular-shaped fitting hole to be fitted with the loading cam, 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.
