Abstract
The present disclosures relates to a toroidal continuously variable transmission which includes: a rotating shaft; a pair of outside disks supported by a rotating shaft to rotate in synchronization with the rotating shaft; an inside disk supported by the rotating shaft to rotate relative to the rotating shaft; a pair of rolling bearing units, each including a radial rolling bearing capable of supporting an axial load to support the inside disk so that relative rotation with respect to the rotating shaft is possible; a plurality of power rollers arranged between the axial inside surfaces the outside disks and the axial outside surfaces of the inside disk to transmit power between them; and a preloading mechanism elastically pressing the outer ring of the radial rolling bearing in the axial direction.
