Zusammenfassung:	PURPOSE:To obtain four-wheeled drive safely in any condition by means of causing the circumferential speed of a front wheel and a rear wheel to be equal by equipping at least two stages-transmission mechanism between the shafts of the front wheel and the rear wheel. CONSTITUTION:A transmission 9 is equipped between the driving shafts 7 and 8 of a rear wheel and a front wheel. Consequently, the revolution of the driving shaft 7 of the rear wheel is transmitted to a gear 20 from a gear 19. The revolution force transmitted as above, is further transmitted to a gear 12 or a gear 13 from either of a high speed gear 10 or a low speed gear 11 fitted to subshaft 21, and the front wheel driving shaft 8 is rotated. The selection for these gear- engagement is achieved by regulating the position of the clutch 23 equipped between the gears 12, 13, and the position of the clutch 23 is requlated by the operation of a shift-lever.
