Differential apparatus
A differential apparatus having a pinion gear revolving around an axial line and a side gear engaging with the pinion gear and configured to transmit power by rotation of the side gear, including: a differential case housing the pinion gear and the side gear and rotating around the axial line; and an intermediate member disposed between the side gear and an inner wall of the differential case. The intermediate member has a scooping-up portion scooping up oil outside of the differential case.
1. A differential apparatus having a pinion gear revolving around an axial line and a side gear engaging with the pinion gear and configured to transmit power by rotation of the side gear, comprising:
a differential case housing the pinion gear and the side gear and rotating around the axial line; and
an intermediate member disposed between the side gear and an inner wall of the differential case, wherein
the intermediate member has:
a scooping-up portion scooping up oil from outside of the differential case;
a supported portion supported by the side gear and the inner wall of the differential case; and
a connecting portion extending from the supported portion to outside of the differential case through a window opened in the differential case and connecting the supported portion and the scooping-up portion.
2. The differential apparatus according to claim 1 , wherein
the differential case has a pair of the windows, wherein
the intermediate member has:
a pair of the scooping-up portions;
a pair of the supported portions; and
a pair of the connecting portions extending from the pair of supported portions to outside of the differential case through the pair of windows and connecting the pair of supported portions and the pair of scooping-up portions, wherein
one and another of the pair of supported portions engage each other.
3. The differential apparatus according to claim 2 , wherein
the supported portion is formed annularly and an inner diameter of one of the pair of supported portions and an outer diameter of another of the pair of supported portions approximately match.
4. The differential apparatus according to claim 3 , wherein
the one of the pair of supported portions has a notch portion on a side opposing a side from which the connecting portion extends.
5. The differential apparatus according to claim 1 , wherein
the differential case has an engaging portion engaging with the connecting portion to stop rotation of the supported portion.
6. The differential apparatus according to claim 1 , wherein
the scooping-up portion forms an oil storage space recessed inward in a rotation radial direction of the differential case.
