<p>PROBLEM TO BE SOLVED: To improve the butt condition and the load condition of a differential gear in a penetrating hole by forming a bearing division on the end part of a space pin, and forming a sliding bearing part which is matched with the sliding bearing division on an outside in the axial direction of the basket division. SOLUTION: An opening port 16 for improving that a lubricating material flows into an inner chamber is arranged on a differential basket 11. A cover member 13, and disk materials 39, 40 are provided with coaxial passing opening ports 17, 18, and a power shaft is inserted passing a passing opening port. Sleeve projecting parts 19, 20 are formed on cover members 13, 14 coaxially with the passing opening port, and bearing member is inserted and fitted to the sleeve projection part. In a space pin 30, a sliding bearing division 31 is formed on an end part. The sliding bearing division is guided in a bearing part 32 which is constituted in a disk member 40 as a drilling hole. It is, thus, possible to improve an ununifom load condition generated along high friction generated on a tooth top on the basis of reaction of a differential gear and the length of the differential gear.</p> |
