Abstract
A fastening structure for a ring-gear and a differential case comprises a differential case which is provided with: a ring gear having a gear section formed on the outer peripheral surface thereof, and a plurality of notch portions formed on the inner peripheral surface thereof; a press-fitting surface whereon the ring gear is press-fitted; and a flange section which is forced against and caulked to the notch portions, at the end of the press-fitting surface. After the ring gear has been press-fitted to the press-fitting surface, the flange section is forced toward the notch portions, and thus the differential case is caulked and fastened to the ring gear. The notch portions have stepped surfaces , and thus rattling generated during torque transmission can be suppressed.
