ABSTRACT:
A differential device for a vehicle includes a pair of shafts extending into a housing, a pair of side gears connected respectively to the shafts, and at least one pair of element gears having respective screw gear portions meshing with respective screw gear portions of the side gears. The element gears have respective coupling gear portions in mesh with each other. The pair of element gears are received in an opening formed in the housing. Each of the element gears is rotatably supported on a journal pin which is removably supported at its opposite ends on a pair of opposed receiving surfaces respectively defining the opposed ends of the opening which are spaced from each other in a direction of the periphery of the housing. A friction-adjusting washer is interposed between the end face of the element gear and the receiving surface.
