ABSTRACT OF THE DISCLOSURE A type of stepless speed change gear whrein an axially movable speed changing ring is frictionally engaged with a plurality of conical roller is improved its durability and is reduced its weight by a provision of a flat annular power transmitting surface and an annular power transmitting surface of arcuated cross-sectional contour on the bottom portion of the conical roller. A force generated by a contact gene- rating device is applied to the conical rollers at the above annular power transmitting surface of arcuated cross-sectional contour, and the conical rollers is advanced by this force into a space between the speed changing ring and another frictionally engaging member as a wedge so that required contact pressures ale applied on the frictionally engaging points.
