A ratio-varying component for a transmission of the toroidal-race rolling- traction type, in which each of the rollers (1) transmitting torque between an input disc (51, Fig. 3) and a corresponding output disc (40) is positioned hydraulically by means of an attached hydraulic piston (5) and cylinder (6) combination, in which a ll the cylinders lie to the same side of a common plane (43a) including the axis (43) of the discs. The cylinders may be supported on a common block-like structure (41), in which hydraulic conduits (31a, 32a, 37a, 44) may be contained.
