PURPOSE:To prevent earth and dust from adhering to level, by minimizing the size of the vehicle body in such a manner that the input shaft of a change gear, to which the engine power is transmitted by a belt, is positioned higher than the engine driving shaft, and the output shaft to the axle is positioned lower than the driving shaft. CONSTITUTION:The input shaft 47 of a change gear 41 is arranged higher than driving shaft (not shown) of engine 39, and the output shaft 55, 57 are arranged lower than the driving shaft (not shown). A stepless change gear 43 transmits the power in way of the belt laid around the variable speed pulleys 49, 51 secured respectively to the driving shaft of the engine 39 and the input shaft 47 of the change gear 41. With this constitution, the adhesion of earth and dust to level is prevented due to the belt positioned higher than usual, and transmitting shafts 59, 61 may be almost arranged horizontally. Thereby, the power transmission of the belt can be performed smoothly and the construction of the vehicle can also be minimized in size. |
