    Abstract: A ring gear mounting structure is configured such that a ring gear (10) is fitted onto a supporting portion (8), and the ring gear (10) abuts against a stopper portion (11) that protrudes from on one end portion of the outer peripheral surface (9) in a rotational axis direction of the ring gear (10). A groove (14) is formed in a portion of the outer peripheral surface (9) that is on the stopper portion (11) side of the outer peripheral surface (9). A portion of the outer peripheral surface (9), which is on a side opposite the stopper portion (11) across the groove (14), is a press-fitting surface (20) that the ring gear (10) is press-fitted onto and contacts. A predetermined gap (C1, C2) is formed in a radial direction of the ring gear (10) and the rotational axis direction of the ring gear (10).

    Abstract: The present invention addresses the problem of providing a welding structure capable of facilitating the inspection of quality of a welded portion and of improving the quality and function of a welded component in which a plurality of members are joined at the welded portion. In one embodiment of the present invention, the welding structure includes: a circular ring gear having a gear portion and a gear joint; and a case having a case joint joined to the gear joint. In the welding structure, the ring gear is fixed to the case at both axial direction ends of the ring gear by welded portions at which gear side welding surfaces, which are the welding surfaces of the gear joint, and case side welding surfaces, which are the welding surfaces of the case joint, are welded. At least one side welded portion in the axial direction is disposed outside the gear edge surface of the gear portion in the axial direction. Alternatively, at at least one side welded portion in the axial direction, the gear side welding surface and the case side welding surface are formed so as to be tilted with respect to the axial direction.

    Abstract: A fastening structure (1) for a ring-gear (3) and a differential case (2) comprises a differential case (2) which is provided with: a ring gear (3) having a gear section (4) formed on the outer peripheral surface thereof, and a plurality of notch portions (5) formed on the inner peripheral surface thereof; a press-fitting surface (6) whereon the ring gear (3) is press-fitted; and a flange section (8) which is forced against and caulked to the notch portions (5), at the end of the press-fitting surface (6). After the ring gear (3) has been press-fitted to the press-fitting surface (6), the flange section (8) is forced toward the notch portions (5), and thus the differential case (2) is caulked and fastened to the ring gear (3). The notch portions (5) have stepped surfaces (14, 15), and thus rattling generated during torque transmission can be suppressed.
