PURPOSE:To reduce the turning radius by journaling a pair of rocking supports juxtaposed respectively with plural wheels in the forward/rearward direction rockably to the right and left sides of a frame of vehicle and selecting a wheel to be grounded while rocking said supports. CONSTITUTION:A tubular trunnion shaft 3 is mounted in the right/left direction through a supporting frame 2 below the rear section of a vehicle frame 1, while trunnion cases 4, 5 are journaled rockably to the opposite end sections of said shaft 3. Plural rear wheels 6-8 are juxtaposed in the forward/rearward direction a the opposite end sections in front and rear of said cases 4, 5, while respective rear wheels 6-8 are made drivable by means of the engine of vehicle through transmission means 10, 11. Hydraulic cylinders 14, 15 are mounted at the opposite sides of the rear section of the vehicle frame 1 respectively through the brackets 12, 13.
