Abstract

PURPOSE:To raise the height from the ground surface by connecting a front frame and a rear frame on different levels so that the former is high and the latter is low and arranging a front differential case in the space formed by the lower surface of the front frame and the front of the rear frame. CONSTITUTION:A frame is separated into a front frame 19 and a rear frame 26 in the vicinity of an engine 15 and both frames are connected integratedly on different levels so that the front frame 19 is high and the rear frame 26 is low. In other words, a transverse frame 29 is provided between the right and left front frames 19 and the rear center pin bearing unit 31 of a front differential case 21 is fixed to the lower surface and then the rear center pin bearing unit 30 is fixed to the front end face of the rear frame 26. In addition, the front differential case 21 is arranged in the space formed by the lower surface of the front frame 19 and the front of the rear frame 26. As a result, the distance from the ground surface to the lower end of the front differential case 21 is increased and the contact with an obstacle is prevented.
