Abstract
A continuously variable transmission device includes an input shaft, an output shaft, an input roller, an output ring, a transmission ring, a plurality of planetary rollers including a first conical portion externally contacted to the input roller and internally contacted to the output ring and a second conical portion internally contacted to the transmission ring, a movable holder which holds the plurality of planetary rollers to be capable of rotating about each rotating axis line and revolving about the center axis line, and a loading cam mechanism (CM, CM) which generates a thrust load. The input roller, the output ring, and the transmission ring are formed so that each face being contacted to the planetary roller is formed to have a convex curved face. The planetary rollers are supported by the movable holder so that an inclination angle of a rotation axis line against the center axis line is variable.
