ABSTRACT:
In a toroidal continuously variable transmission having a plurality of power rollers interposed between input and output disks under axial preload and using a tapered roller bearing as a power roller bearing, a radial load and a thrust load acting on an inner race are received or supported by way of the tapered roller bearing. An inner raceway surface formed on the inner race is located to be offset from a line of action common to a radial component of a contact pressure acting on a contact point between the inner race and the input disk and a radial component of a contact pressure acting on a contact point between the inner race and the output disk toward an outer race.
