Abstract
A driving force distribution/transmission device suppresses a shift of lubrication oil when a vehicle makes a turn, smoothly lubricates sliding parts, and improves reliability. The driving force distribution/transmission deviceincludes a gear input rotary memberand a gear output rotary memberthat are interlocked to transmit a driving force through the meshing of a drive pinion gearand a ring gear; and a left-right pair of clutch output adjusting mechanismsandcoupled with both ends of the gear output rotary member, to carry out a driving force output adjustment through the engagement of frictional multiplate clutches. A closed and partitioned gear roomcontains the drive pinion gearand ring geartherein. The main clutchesare contained in a left-right pair of closed and partitioned clutch rooms, respectively. Lubrication spaces in the three separate rooms, i.e., the gear roomand the left-right pair of clutch roomsseparately seal gear oil and clutch oil therein.
