PURPOSE: To lower a fitting position of an engine for a lower deck body by rerspectively driving the drive shafts for driving front wheels and rear wheels via speed change mechanisms and coaxially providing both the drive shafts.
CONSTITUTION: A transmission case 6 is attached to a deck behind an engine 4. Revolution of an input shaft 7 which is driven by the engine 4 is transmitted to a driven shaft 8 held on the upper part of the transmission case 6 via a for example stepless speed change wrapping transmission mechanism 9. Front and rear driving shafts 10, 11 are coaxially supported at the lower part of the transmission case 6 and front wheels 2 are driven by both a journal joint shaft 12 connected to the front driving shaft 10 and differential gears. Rearward front wheels 13 and rearward rear wheels 14 are run together with each other by a chain mechanism 16. The rearward front wheels 13 are driven by both a journal joint shaft 17 connected to the rear driving shaft 11 and the differential gears.
