An infinitely variable speed drive mechanism which is specifically adaptable for automotive applications is made up of a single ball or spherical element interpositioned between drive and driven members in opposed facing relation to one another on opposite sides of the ball, each of the drive and driven members having generally annular, frusto-conical surface portions engageable along one of the surfaces of engagement with the ball, and control rollers are mounted under compression against a surface portion of the ball so as to urge the ball into balanced frictional engagement with the drive and driven members while establishing the axis of rotation of the ball and determining the speed ratio imparted through the ball between said drive and driven members.
