VEHICLE DRIVE DEVICE

TASKTo provide a vehicle drive device that easily allows a reduction in the size of a case and a reduction in production costs.MEANS OF SOLVING THE PROBLEMA vehicle drive device includes: a case (5) that accommodates a rotary electric machine (1), an input member (2), a counter gear mechanism (3), and a differential gear device (4); and a support member (7) that is a separate member from the case (5), and is fixed inside the case (5). The case (5) includes a tube-like peripheral wall portion (51) surrounding an outer side of the rotary electric machine (1), the input member (2), the counter gear mechanism (3), and the differential gear device (4) in a radial direction (R), a first side wall portion (52) disposed on the axial first side (L1) with respect to the peripheral wall portion (51), and a second side wall portion (53) disposed on the axial second side (L2) with respect to the peripheral wall portion (51). The peripheral wall portion (51) includes a first peripheral wall portion (511), and a second peripheral wall portion (512) joined to the first peripheral wall portion (511) from the axial second side (L2). An axial first-side (L1) end of each of the counter gear mechanism (3) and the differential gear device (4) is supported by the first side wall portion (52), and an axial second-side (L2) end of each of them is supported by the support member (7).
