Toroidal-type continuously variable transmission

摘要

A toroidal-type continuously variable transmission in which a section area of a support plate portion 7 forming a trunnion 6 is expressed as S, the length thereof is expressed as L, and the section coefficient thereof is expressed as Z, the ratio (S x L) / Z is specified in the range of 10 - 35 and, more preferably, in the range of 15 - 30. This can make even the load distribution of balls forming the thrust ball bearing, thereby being able to attain the above object.
