ABSTRACT:
For a toroidal type continuously variable transmission, the end portion of a radial needle bearing provided for a trunnion is protruded from the inner face of the trunnion. Also, the inner face of the trunnion is made substantially flat. Therefore, the processing of the trunnion is made easy, and the holder of the thrust needle bearing can be easily positioned simultaneously. Also, the structure is arranged to enable the recess formed on the trunnion to engage with the extrusion formed on the holder, thus preventing any plane pressure from being exerted excessively on the rolling surface of the needles of the thrust needle bearing, as well as preventing the needles from falling out of the pockets of the holder.
