Abstract
In a differential device including a differential case having a case main body with an access window, a flange part includes: a first flange part outside a region sandwiched by paired imaginary straight lines passing through an axis and inner ends, on one and another sides in a peripheral direction of the case, of the window when viewed on a projection plane orthogonal to the axis; and the second flange part in the region. The second flange part includes a predetermined region spaced in the peripheral direction from a border part with the first flange part and capable of avoiding stress concentration around a degassing passage in the predetermined region when a thrust load acts on the flange part so as to generate stress resisting inclination thereof. The degassing passage is disposed only in the first flange part, only in the predetermined region, or only in both of them.
