PURPOSE:To allow the road clearance to be regulated with simple constitution, by connecting a front axle housing and a front wheel side gear case via an intermediate gear case. CONSTITUTION:A turning side gear case 2 bearing a front wheel shaft 1 is fitted to a stationally side gear case 3 about a turning central shaft 4, and an outer end of a front axle housing 6 bearing a front wheel driving shaft 5 therein and an inside end of the stationary side gear case 3 are connected by connecting devices K1, K2 via an intermediate gear case 7. When the right and left front wheel driving shafts 5 are driven, the driving shafts 9 cause the front wheel shafts 1 and the front wheels 39 to be driven via spur gearing mechanisms 15 and gear mechanisms 16, and when a drug arm 26 is rotated by a steering mechanism, together with the turning side gear case 2 the front wheel 39 can be turned to the right or left about the turning central shaft 4. |
