Abstract: PURPOSE:To enlarge the range of speed change ratio of a stepless speed change gear, by providing a low gear pair and high gear pair between the output shaft of a belt-driven stepless speed change gear and another output shaft arranged in parallel with said output shaft. CONSTITUTION:The clutch 24 is released when starting or travelling with low speed. Consequently the power is transmitted from the first output shaft 13 through first gear 17 in a low gear pair 25, third gear 21 and first oneway clutch 20 to the second output shaft 19. Consequently the speed is dropped lower than the case where only stepless speed change gear 3 is employed. Upon increase of car speed, the clutch 22 is fastened to fix the fourth gear 22 to the second output shaft 19. Consequently the power is transmitted from the first output shaft 13 to the second and fourth gears 18, 22 thus to rotate the second output shaft 19. Since the second gear 18 and fourth gear 22 are a high gear pair 26 equipped with a oneway clutch and a hydraulic clutch, the second output shaft 19 will rotate with higher speed than the first output shaft 13.
