VEHICLE DRIVE DEVICE

An offset gear mechanism (3) in a power transmission mechanism is arranged on a different axis (A2) in an axis-orthogonal direction (Y) from an axis (A1) on which a rotary electric machine (8) and an output member are arranged. The rotary electric machine (8) and the power transmission mechanism are arranged in a first housing chamber (E1), and an inverter module (5) and a power source module (7) are arranged in a second housing chamber (E2). The second housing chamber (E2) includes an upper area (E3) on an upper side (Z1) overlapping the rotary electric machine (8), and a lateral area (E4) on the axis-orthogonal direction first side (Y1) overlapping the offset gear mechanism (3). At least a part of the inverter module (5) is arranged in the upper area (E3), and at least a part of the power source module (7) is arranged in the lateral area (E4).
