ABSTRACT:
A ratio-varying component for a continuously-variable-ratio transmission of the toroidal-race rolling-traction type, in which each roller (20) spans the toroidal clearance between its respective input (4, 5) and output (11, 12) discs diametrically and the roller center (20b) is capable in operation of limited movement back and forth along the center circle (22a) of the clearance, and in which stop means (40, 41; 30, 33) are mounted adjacent both the outer and inner edges of the part-toroidal races (22, 23) on the discs, to prevent the rollers from running off the edges.
