摘要： In the toroidal-type continuously variable transmission, the torque transmission shaft 15 includes a flange portion 29a formed in one end thereof, while a securing portion 43 is formed in the end-face side half section of the flange portion 29a so as to be able to secure a tool thereto when tightly fastening a loading nut 19 to a external thread portion 40 formed in the torque transmission shaft 15. And, the outer peripheral surface of the securing portion 43 is formed as a polygonally cylindrical shape having four or more flat surfaces. Also, after the torque transmission shaft 15 is heat-carburized and the surface of a cylindrical portion 44 formed in the torque transmission shaft 15 is removed, the external thread portion 40 is worked, which makes it possible not only to secure the hardness of the adjoining portions of the external thread portion 40 but also to control the hardness of the external thread portion 40 itself. Further, branch oil supply passages 39 and 39 used to supply oil to ball splines 17 and 17 are formed at the positions of the torque transmission shaft 15 that are shifted in the axial direction of the torque transmission shaft 15 from the positions of balls 37, 37, which respectively construct the ball splines 17 and 17.

摘要： An outer race of a thrust ball bearing supporting a thrust load applied to a power roller is rotatably supported around a displacement shaft. A portion in which the contact pressure between an outer race track and the rolling surface of a rolling member is high changes so that the fatigue of the outer race track does not progress locally. Also, the power roller and the outer race are subjected to predetermined treatment and working. Irrespective of a great thrust load applied during operation, stress is alleviated and the lubricating property of the portion of contact is made good to thereby prevent cracks or early wear from occurring.
