摘要： A trunnion of a toroidal-type continuously variable transmission has a support plate portion for supporting a displacement shaft and a pair of bent wall portions respectively bent toward the inner surface side of the support plate portion. The support plate portion and the pair of bent wall portions cooperates together in defining a pocket portion for storing a power roller therein. Pivot shafts are disposed concentrically with each other on the outer surfaces of the pair of bent wall portions. The pair of bent wall portions are connected together by a connecting member. The connecting member includes a pressure receive portion contactable with the inner surface of the pocket portion in a direction intersecting substantially at right angles to the thrust direction and receiving a pressing force acting on the pocket portion to crush the pocket portion.

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.
