ABSTRACT:
A planetary gear device as a central differential is provided. The planetary gear device has a first sun gear connected to an output shaft of a transmission, a carrier, first and second planetary pinions rotatably supported on the carrier through a shaft, and a second sun gear. The first planetary pinion is engaged with the first sun gear, and the second planetary pinion is engaged with the second sun gear. Each of the sun gears and the planetary pinions is arranged such that resultant force produced by a separative load and a tangential load at a contact point of the pinion and the sun gear is exerted on a bearing on the shaft, so that friction at the bearing produces a differential operation restricting torque.
