Claims

[Scope of utility model registration request]

In a center differential that transmits the engine output of an automobile via a transmission and distributes it to the front wheels and rear wheels, there is an input section that receives driving force from the transmission, and an input section that receives driving force from the transmission. A center differential body that distributes driving force between the front wheels and the rear wheels, and an output section that outputs the driving force distributed through the center differential body to the front wheels and the rear wheels. The center differential main body includes a carrier that receives driving force from the input section, a planetary pinion attached to this carrier, and a planetary pinion that receives driving force from the planetary pinion and transmits this driving force to each output section. The input section is composed of an input gear and an input case, and the input gear is located at one end of the planetary gear mechanism, and the carrier is located at one end of the planetary gear mechanism. The input case is provided at the other end, and the input case is provided at one end and surrounds the input gear supporting part that pivotally supports the input gear, and the other end is provided to surround the main body of the planetary gear mechanism. A roller supporting the input part on one end side of the planetary gear mechanism, comprising a case part and a carrier connection part provided at an end of the case part and connected to the carrier so as to move the carrier in the axial direction. A planetary gear type center differential structure characterized by the provision of bearings.
