Abstract
In a toroidal continuously variable transmission, a roller-and-cage bearing assembly is interleaved between a power-roller outer ring and a trunnion power-roller accommodating portion to permit a parallel translation of a power roller in an axial direction of input and output disks. A cage of the roller-and-cage bearing assembly is formed with an oval slotted hole. A disk-shaped member is attached to the trunnion power-roller accommodating portion. The slotted hole and the disk-shaped member are fitted to each other to define a predetermined clearance that limits a displacement of the roller-and-cage bearing assembly in a direction perpendicular to both a rotation axis of the power roller and a trunnion axis to a set displacement.
