ABSTRACT:
The toroidal type continuously variable transmission includes a power roller which is pinched between confronting faces of an input disk and an output and which can be tilted, an input shaft which rotates together with the input disk, and an output gear which is coupled to the rear side of the output disk. Thrust and radial loads which are imposed upon the output disk are supported by an angular bearing which is provided on the other side of the output gear from the output disk. The input shaft penetrates through the output disk and the output gear so as to be freely rotatable with respect to them both, and a radial bearing is provided which supports load in the radial direction between an inner circumferential surface of the output gear and the input shaft. This radial bearing cooperates with the angular bearing, and thereby the strength for supporting radial loads upon the output gear is enhanced.
