ABSTRACT:
A method of manufacturing a traction roller for a continuously variable transmission comprises placing a layer on a hollow cylindrical material having the volume substantially equal to the traction roller, performing axial pressure forging of the cylindrical material to obtain a work having the axial length substantially equal to that of the traction roller, performing axial die forging of the work to form side wall and outer peripheral surface of the traction roller, and grinding the work subjected to die forging to obtain a finished product of the traction roller.
