Abstract
A main case includes a specific facing surface that faces, in a radial direction, a first side surrounding portion of a differential case that surrounds a first side projection disposed so as to project to an axial first side with respect to a differential input gear in a differential gear mechanism, and that is formed so as to surround the first side surrounding portion from a lower side, and a side wall surface that is formed so as to extend to radial inside from an end portion of the specific facing surface on the axial first side. An oil accumulating portion in which oil is accumulated is formed in a space surrounded by the specific facing surface, the side wall surface, and a surface of the differential input gear facing the axial first side.
