Abstract
A preloading mechanism (,) of a toroidal continuously variable transmission applies a predetermined preload to disks (,) by belleville springs (,). The input disk (,) displaces in such a compressing direction of the belleville spring (,) as the speed ratio increases. The displacement of the input disk (,) is limited by a spacer (,), so the clearance (S) of the belleville springs (,) is never zero and a large force is prevented from acting on the belleville springs (,).
