The planetary gear for the automobile differential mechanism comprises a wheel shaft and a wheel body arranged on the wheel shaft, an inclined face is arranged on the outer wall of the wheel body, a plurality of outer gears are arranged on the inclined face in an annular array mode, the end, away from the wheel shaft, of the wheel body is provided with a conical inclined face, and a plurality of balls are arranged in the conical inclined face through an formed containing cavity. The end, close to the outer gear, of the gear body is provided with a hoop mechanism for limiting the balls, the balls can be installed in a limited mode through matching of the hoop mechanism and the conical inclined face, the friction coefficient between the planetary gear and the inner wall of the differential mechanism shell is reduced through rolling installation of the balls, and therefore the differential mechanism can be installed more stably. And the service life of the planetary gear is prolonged. 本实用新型涉及汽车差速器用行星齿轮，包括轮轴和其上设置
