ABSTRACT:
A toroidal type continuously variable transmission has an input shaft to which a rotation torque is input, an input side disk and an output side disk that are concentrically and rotatably supported by the input shaft in a state that an inner peripheral surface of the input side disk opposes to an inner peripheral surface of the output side disk, a power roller held between the input side disk and the output side disk and a hydraulic loading device applying predetermined pressing force so that the power roller is pressed between the input and output side disks. Fine grooves are formed on at least a radially inner part of the inner peripheral surface of the input side disk and at least radially outer part of the inner peripheral surface of the output side disk, respectively.
