DIFFERENTIAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/086344
Kind Code:
A1
Abstract:
Provided is a differential device in which power is inputted to a differential case through a helical ring gear, wherein: the differential case (C) is provided with a ring gear (Cg), and a pair of side wall plates (Ca, Cb) that have a boss (B) on the inner peripheral end and that are joined at the outer peripheral end to both axial ends of the ring gear (Cg); the axial distance between the outer lateral surfaces of the side wall plates (Ca, Cb) increases diametrically inward; the thicknesses of the first portions (a1) of the side wall plates (Ca, Cb), which extend to the outer peripheral ends from predetermined middle parts (m) diametrically near the ring gear (Cg), gradually increase towards the outer peripheral ends; and the inner-side surfaces of the first portions (a1) of the side wall plates (Ca, Cb) curve axially inward towards the ring gear (Cg). An increase in the weight of the differential case due to the ring gear can thereby be suppressed, and the rigidity and strength of the differential case can be increased.
