Abstract
The invention relates to a stepless speed change device which comprises: an input shaft and an output shaft concentric to each other, a disc progressively thinner toward its outer periphery and fixed to the input shaft, a hollow cylinder fixed to the output shaft for enclosing the disc, a ring progressively thinner toward its inner periphery opposite to that of the disc and fixed to an inner circumference of the hollow cylinder in the same plane as that of the disc, and an intermediate transmitting device having two discs for embracing the ring and the disc on both sides thereof and being movable from a concentric position with the input and output shafts to eccentric positions with desired eccentricities therefrom in a stepless manner. With the above arrangement, the input shaft may be used as an output shaft, and the output shaft may be used as an input shaft.
