PROBLEM TO BE SOLVED: To effectively prevent seizure of a pinion slide part or an engagement part of a pinion and a side gear, even when a tooth part of the side gear is separated far from an output shaft by enlargement of the side gear or when the pinion rotates at high speed, in a differential device.SOLUTION: A side gear S has a shaft part Sj connected to an output shaft A, and a flat intermediate wall part Sw integrally connected between the shaft part Sj and a tooth part Sg of the side gear S separated from the shaft part Sj toward the radial outside of an input member I. In the intermediate wall part Sw of at least one side gear S, provided is a through oil passage 15 of which both ends are opened to the inside surface and outside surface of the intermediate wall part Sw respectively.SELECTED DRAWING: Figure 1 |
