<p><P>PROBLEM TO BE SOLVED: To provide a driving force distributing device which can sufficiently secure an oil amount of lubricating oil used for lubrication and cooling in all rotation ranges from a stop state to a high-speed travelling state of a vehicle, which makes it possible to efficiently secure lubrication performance and cooling performance, and which can realize improvements in performance stability and durability. <P>SOLUTION: The driving force distributing device 1 includes a storage part 30 which temporarily stores the lubricating oil filled into a rear differential gear case 2. The lubricating oil in the rear differential gear case 2 is supplied to a clutch mechanism in a coupling case 20 through the medium of a communication opening 31 by the rotation of the coupling case 20, and the communication opening 31 communicating between the lower part of the rear differential gear case 2 and the lower part of the storage part 30. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
