PROBLEM TO BE SOLVED: To reduce a power loss and tire wear, which are caused by tire slipping associated with vehicle turning traveling of vehicle driving wheels having right and left wheels configured as coaxial double wheels, respectively.SOLUTION: A pair of right and left outside wheels of right and left driving wheels configured as coaxial double wheels, respectively, is driven via a pair of right and left first axles by a first differential gear mechanism. A pair of right and left inside wheels is driven via a pair of right and left second axles concentrically extended as hollow shafts around the first axles, by a second differential gear mechanism sharing an input rotation member with the first differential gear mechanism.SELECTED DRAWING: Figure 1 |
