Toroidal type continuously variable transmission
 The total of thrust loads acting on first, second, and third angular ball bearings upon operation of a transmission is reduced. In order to reduce torque losses of the angular ball bearings, a toroidal type continuously variable transmission is arranged so that a thrust load based on the counterforce upon operation of a compression device is received by the third angular ball bearing, and the difference between a thrust load acting on an input-side disk and a thrust load acting on an output-side disk acts on an output shaft. A thrust load corresponding the difference is received by one of the first and second angular ball bearings.
