ABSTRACT:
An inner surface16aof a torque transmitting disc of a toroidal type continuously variable transmission can be finish-worked without also enhancing accuracy of a cylindrical surface as an outer peripheral surface of the disc. The inner surface is finish-worked with super finish while urging a working surface of a grindstone against the inner surface. In this case, roller shoes are rollingly contacted with the inner surface to prevent the disc from being radially displaced under force from the working surface.
