摘要
A method for attaching a ring gear 12 to a differential case 13 includes: a first step of fitting the ring gear 12 onto an outer peripheral side of the differential case 13; and a second step of outwardly deforming a caulk-fixing part 52 of the differential case 13 to prevent the ring gear 12 from being dropped out from the differential case 13. In the second step, a jig 60 having an inclined surface 61 that can contact an inner peripheral surface 53 of the caulk-fixing part 52 of the differential case 13 is pushed along a rotational axis direction of the differential case 13 to outwardly deform the caulk-fixing part 52. The inclined surface 61 of the jig 60 and/or at least a part of the inner peripheral surface 53 of the caulk-fixing part 52 are subjected to a surface treatment to increase a friction between the inclined surface 61 of the jig 60 and the inner peripheral surface 53 of the caulk-fixing part 52.
