A continuously variable transmission device of the type having planetary members (25) in rolling contact with radially inner (23) and outer (26) races each comprising two axially spaced parts, with control means (30) for selectively varying the axial separation of the two parts of one race and thus the radial position of the planetary members (25) in rolling contact therewith, in which there are provided means sensitive to the torque applied to a drive-transmitting member of the transmission operable both to determine the compensating variation in the separation of the two parts of the other race and thus the transmission ratio of the device and to vary the forces exchanged between the planets (25) and the races (23, 26) normal to the interface between them.
