ABSTRACT:
Each of the power rollers incorporated in a toroidal-type continuously variable transmission is arranged to prevent damage such as cracks, from being created thereon when the transmission is in operation. The inner circumferential surface of each power roller is configured continuously with a smaller diametral section close to the outer edge surface, a larger diametral section on its opposite side, and a stepping portion connecting them. A needle bearing for supporting the power roller on a displacement shaft is provided inside the larger diametral section. Due to the portion of the smaller diametral section thus provided, the stress capacity is increased with respect to the tensile stresses exerted at the time of operation; thus preventing damage such as cracks, from being easily created.
