Abstract
A differential for a wheeled motor vehicle comprises a differential gear unit, and a differential case for housing therein the differential gear unit. The differential case is rotatable about its rotation axis in normal and reverse directions at a position above an oil level of a lubricating oil. The differential case includes a portion having an oil inlet opening formed therethrough, the oil inlet opening communicating the interior of the differential case with the outside of the same; and an oil dipping up structure that dips up the lubricating oil to force the same to enter the interior of the differential case through the oil inlet opening when the differential case rotates about the rotation axis.
