PURPOSE:To obtain a speed change gear having the speed-change pattern for easy speed-change by utilizing the shaft of a sub-speed change gear and the shaft of a main speed change gear in common. CONSTITUTION:Though independent speed change is permitted in each of a main speed change gear 1 and a sub-speed change gear 2, the range of the synthetic speed-change of the captioned speed change gear consisting of the main speed change gear 1 and the sub-speed change gear 2 consists of the multiplication of the speed-change range of the main speed change gear 1 by two kinds of the speed-change range of the sub-speed change gear 2. Since the main speed change gear 1 and the sub-speed change gear 2 are directly connected by an intermediate shaft 1h. Since the main speed change gear 1 and the sub-speed change gear 2 are simultaneously shifted on shifting of a shift lever, the so-called H-type shift pattern is permitted.
