Abstract
A gear transmission comprising a driving transmission shaft, a driven transmission shaft, a gear shaft between the two transmission shafts, three speed change gears of different diameters mounted on the gear shaft, an auxiliary speed change shaft carrying three gears of different diameters respectively in mesh with the speed change gears, and two clutch members provided between one or the other of the transmission shafts and the gear shaft. Each clutch member provides two speeds by switching between a position to connect one of the transmission shafts to the gear shaft and a position to connect the transmission shaft to one of the speed change gears. Thus the gear transmission provides a total of four speeds.
