A differential apparatus including a rotating body configured to rotate around a rotation axis to transmit power to a differential mechanism, and a groove formed on the rotating body and configured to guide an oil scooped up by rotation of the rotating body inward in a rotation radial direction of the rotating body.

Differential apparatus

A drive shaft () as a rotating body includes an engaging portion () engaging with a side gear () and a sliding portion () abutted by a differential case (). The engaging portion () includes a plurality of engaging grooves (). The engaging grooves () engage with the side gear (). The engaging portion () includes a small diameter portion () at a position corresponding to between the drive shaft () and the differential case () in a direction of a rotational axis L. The small diameter portion () has an outer diameter smaller than the outer diameter of the sliding portion ().

Rotating body, power transmission device using same, and rotating body production method

A power transmission apparatus including: a case having a first oil storage configured to store oil at a bottom thereof; a rotating body rotatably housed in the case and having a second oil storage configured as an approximately cylindrical rotating body for transmitting power and configured to store oil therein; and an introducing portion configured to introduce oil from the first oil storage into the second oil storage.

Power transmission apparatus

A power system includes: a rotating body; a housing accommodating the rotating body; and a storage portion provided at a bottom of the housing. A part of the rotating body is located in the storage portion. The housing includes: a supply target portion; and a direction changing portion. The direction changing portion includes: a collecting portion that is gradually inclined toward a downstream side in a rotation direction of the rotating body so as to be separated from an outer periphery of the rotating body and that receives the liquid medium scattered by the rotating body; and a guiding portion that is provided so as to cross a lower end of the collecting portion and that is gradually inclined downward toward the supply target portion.
