Abstract
A continuously variable speed converter is provided wherein a plurality of balls are interposed between a pair of friction discs for transmitting rotation of an input shaft to an output shaft connected with a fluid pump. A speed change mechanism is arranged to tilt the rotational axis of each of the balls in each plane, including the axis of the input shaft, to thereby change the output/input speed ratio. Disposed within a main housing carrying the input and output shafts is the fluid pump, which also serves as a pressuring means responsive to fluid delivered by itself so as to apply to the output shaft a thrust force corresponding to the pressure of the fluid, so that efficient power transmission without slippage may be provided between the friction discs and the balls.
