Abstract
Provided is a toroidal continuously variable transmission capable of preventing the application of bending stress to a variator shaft during rotation and the application of an eccentric load to each of support parts even when misalignment between the axis of a fitting hole formed in a post and the axis on which the variator shaft is supported occurs. A thrust bearingwhich determines the position of an output side discin an axial direction and rotatably supports the output side discis fitted into a fitting holeprovided in a post, and a predetermined gap S is provided between the thrust bearingand the fitting holein a direction perpendicular to the variator shaft. Therefore, even when misalignment between the axis of the fitting hole and the axis on which the variator shaft is supported occurs, the axes of the thrust bearingand the variator shaftcan be aligned with each other in the predetermined gap S, thereby preventing the application of bending stress to the variator shaftduring rotation and the application of an eccentric load to each of support parts.
