Abstract
In order to improve the transmission efficiency of a toroidal type continuously variable transmission by reducing the dynamic torque loss of an antifriction bearing, a first output gear is constituted by a pair of helical gears of which the directions of inclinations are opposite to each other, and a second output gear is constituted by a double helical gear. By this construction, a thrust force created in the meshing portion between the first and second output gears is offset and the dynamic torque loss of the antifriction bearing is reduced.
