A variator transmission comprises an input shaft (), an input disc () mounted on the input shaft for rotation therewith and an output disc () facing the input disc and arranged to rotate coaxially therewith, the input and output discs defining between them a toroidal cavity. Two rollers () are located in the toroidal cavity and first and second roller carriage means are provided upon which the first and second rollers respectively are rotatably mounted and end load means () urge the rollers into contact with the input and output discs to transmit drive. The two roller carriage means are mounted on opposite sides of the pivotal axis of a lever () and the pivotal axis of the lever () is movable in both the radial and non-radial directions with respect to the rotational axis of the input and output discs.
