<p><P>PROBLEM TO BE SOLVED: To downsize a final reduction gear device which executes two-step final reduction. <P>SOLUTION: The final reduction gear device is equipped with: a first speed reduction gear group 11 for reducing to output driving force from a drive pinion shaft 9; an intermediate shaft 13 receiving the driving force output from the first speed reduction gear group 11; a differential gear set 15 configured so as to concentrically disposed and interlocked on the intermediate shaft 13 to distribute to output the driving force from the intermediate shaft 13; and a pair of second speed reduction gear groups 17 and 19 for reducing a speed to output the driving force distributed and output from the differential gear group 15, to a pair of rear wheel shafts 21 and 23. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
