Claim Text:
1. A continuously variable transmission device, comprising: a housing; an input shaft which has a center axis line; an input roller which is rotated integrally with the input shaft; an output shaft which is arranged coaxially with the input shaft; an output ring which is rotated integrally with the output shaft; a transmission ring which is arranged movably in a direction of the center axis line as having the center thereof on the center axis line; a plurality of planetary rollers which are arranged at equal intervals in an imaginary conical face having the vertex thereof on the center axis line, each planetary roller including a first conical portion which is externally contacted to the input roller and internally contacted to the output ring and a second conical portion which is internally contacted to the transmission ring; a movable holder which holds the plurality of planetary rollers to be capable of rotating about each rotation axis line and revolving about the center axis line; and a loading cam mechanism which generates a thrust load in the direction of the center axis line, wherein 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 having a predetermined curvature on a plane which includes the rotation axis line of the planetary roller and the center axis line, and the planetary rollers are supported by the movable holder so that an inclination angle of the rotation axis line against the center axis line is variable.
