Abstract
A vehicle drive device includes: a rotating electrical machine; a differential transmission device; a power transmission device; a power module; a wiring portion; and a case. The case forms, above a plane including the axis of a rotation shaft of the rotating electrical machine and the axis of an output shaft, a first, second, and third housing portion. The first portion overlaps the rotating electrical machine as viewed in an axial direction of the rotating electrical machine, and overlaps the power transmission device as viewed in an up-down direction. The second portion overlaps the rotating electrical machine as viewed in a direction perpendicular to both the axial direction of the rotating electrical machine and the up-down direction, and overlaps the output shaft as viewed in the up-down direction. The third portion is adjacent to the first and second portions, and overlaps the output shaft as viewed in the up-down direction.
