Abstract
A toroidal continuously variable transmission includes a preload spring disposed between a rotary assembly including a first disc and a pressing device, and a driving force transmission shaft, and a thrust bearing disposed between a first member and the preload spring, the first member being one of the rotary assembly and the driving force transmission shaft. In a direction of an axis line, a gap is formed between a second member and the thrust bearing, the second member being the other of the rotary assembly and the driving force transmission shaft. A dimension of the gap in the direction of the axis line is less than a deformation amount of the preload spring in the direction of the axis line, at an elastic limit.
