ABSTRACT:
A toroidal type continuously variable transmission includes an input disk mounted on an input shaft; an output disk mounted on an output shaft; and a pair of power roller bearings each of which includes an inner race, an outer race, and a plurality of rolling elements. The inner races are engaged with the input and output disks to transmit the power of the input shaft to the output shaft. The inner races, outer races, input disk and output disk are made of case hardening steel, and are each subjected to a heat treatment in which carburizing or carbonitriding, hardening and tempering are performed sequentially, and then to shot peening, and finished by grinding of a predetermined grinding portion.
