Abstract
A driving force distribution device includes a lubrication path LP supplying lubricating oil from an oil inlet positioned on the case outside a cylinder into a hub of each clutch unit through an oil hole positioned between an external surface of the cylinder of each operation unit and a bearing supporting the same, between a spacer supporting the bearing and a snap ring supporting the spacer, between an internal diameter of the cylinder of each operation unit and an external diameter of a drum of each clutch unit, and in the drum of each clutch unit, allowing left and right lubrication paths for lubrication of left and right clutch units to have the shortest length, and simultaneously, each flow path to have an increased size.
