Title: STRUCTURE FOR JOINING MEMBERS IN DIFFERENTIAL DEVICE
Abstract:
One problem addressed by the present invention is to provide a structure for joining members in a differential device that is able to suppress falling deformation of a ring gear, comprising a helical gear, toward the rotational axis line direction due to a thrust load applied to the ring gear, while avoiding an increase in weight. As a means for solving this problem, provided is a structure for joining members in a differential device wherein a first linking part (32), which is arranged at a first position on the back-surface portion of a ring gear (30), and links a differential case (10) and the ring gear (30), and a second linking part (12), which is arranged at a second position on the back-surface portion, and links the differential case (10) and the ring gear (30), are separated from each other with a cavity portion therebetween.
