Abstract
A power roller (18C, 18D, 20C, 20D) of a toroidal continuously variable transmission is supported by a pedestal (94) such that it is free to rotate. A first roller bearing (96A) supporting the pedestal (94) in the trunnion (17) against a horizontal load which makes a right angle with an input shaft (16) of the transmission, and a second roller bearing (96B, 96C) supporting the pedestal (94) in the trunnion (17) against a vertical load which makes a right angle with the input shaft (16) of the transmission, are provided between the trunnion (17) and the pedestal (94). These roller bearings (96A), (96B), (96C) permit the pedestal (94) to easily displace parallel to the input shaft (16).
