A vehicle drive device comprising: an engine; a hydraulic transmission device constituting a portion of a power transmission path between the engine and drive wheels; and an electric motor, the engine and the hydraulic transmission device disposed to rotate around one axial center, the electric motor disposed with a rotation axial center different from the one axial center, the electric motor coupled to an input-side rotating element of the hydraulic transmission device receiving input of a drive force from the engine, the input-side rotating element being rotatable around the one axial center, the electric motor coupled to the input-side rotating element via an electric motor coupling rotating element coupled relatively non-rotatably to the input-side rotating element, a hydraulic pump rotationally driven by the input-side rotating element of the hydraulic transmission device disposed such that a rotor of the hydraulic pump rotates around the one axial center, and a coupling portion of the electric motor coupling rotating element for the input-side rotating element inserted into a pump-cover through-hole formed on an internal side of the pump-cover through-hole of the hydraulic pump in a radial direction, along with a portion of the input-side rotating element, and coupled relatively non-rotatably to the input-side rotating element in the pump-cover through-hole, in order to couple the input-side rotating element to the rotor.
