Abstract
Disclosed is a stepless speed change gear including a plurality of conical rollers each of which is provided with a conical surface frictionally engaging with a ring-member moved by a speed changing assembly. A surface of concave cross-section frictionally engages with a sun-member on an input shaft, and a flat surface frictionally engages with a non-rotatable disc member. A gear train is provided to extend the speed range to include a speed ratio of 1:1. A release mechanism is provided for the non-rotatable disc member, and a clutch mechanism is provided for direct coupling of the input and the output shaft. Power is transmitted by direct coupling of the input and the output shaft.
