Abstract
Differential case includes multiple oil intake holes being respectively at positions offset from intermediate point between two pinions adjacent peripherally in the case toward the pinions, the holes passing through outer peripheral wall of the case in inside-outside direction and being capable of taking lubricant oil into the case. The holes are formed such that as seen in projection plane orthogonal to rotation axis of the case, axes of the holes extending from inner to outer opening ends of the holes are inclined forward in rotational direction of the case when vehicle travels forward. As seen in the projection plane, the pinions are placed outside areas between first and second imaginary lines, the first imaginary lines joining the axis and one peripheral ends of the inner opening ends, the second imaginary lines joining the axis and the other peripheral ends thereof.
