Abstract:
A vehicle drive device includes: rotary electric machine; rotor support member; friction engagement device disposed at position on inner side in radial direction with respect to a rotor and at which friction engagement device overlaps rotor as viewed in radial direction along radial direction; and a first and second bearing that rotatably support rotor support member. Friction engagement device has a first and second engagement device disposed side by side in axial direction. First piston portion of first engagement device and a second piston portion of second engagement device are disposed separately on both sides in axial direction across a first and a second friction member. First bearing is disposed at a position at which first bearing overlaps first piston portion as viewed in the radial direction. Second bearing is disposed at a position at which second bearing overlaps second piston portion as viewed in the radial direction.
