摘要： A caulked portion is formed by plastic deformation of a cylindrical portion which is formed at the inner end of a shaft member and is reduced in thickness toward the leading end in a diametrical outward direction. The force required to form the caulked portion is reduced, and the caulked portion is less susceptible to damage. Further, the force of the caulked portion for supporting the inner ring is ensured.

摘要： A power roller of a power roller bearing in a half-toroidal type continuously variable transmission is manufactured as follows. In step S1, a work used as material is heated up to a temperature suitable for forging. In step S2, the work is pressed by using a first die set, with its end face being held. In step S3, the work is forged by using a second die set. The work is formed into a work having a curved face corresponding to a traction surface, a hole corresponding to a center hole, and a recess corresponding to a raceway groove. In step S4, the work is punched by using a third die set. In step S5, the work is subjected to a cutting process and a heating process, thereby obtaining the power roller.
