A vehicle drive device (100) includes a first bearing (B1) that supports a second rotary member (RT2) on a first rotary member (RT1) so that the second rotary member (RT2) is rotatable relative to the first rotary member (RT1), and a second bearing (B2) that supports the first rotary member (RT1) on a case (4) so that the first rotary member (RT1) is rotatable relative to the case (4). The first rotary member (RT1) has a support outer peripheral surface (11a) that faces an outer side (R2) in a radial direction, and a first radial support surface (13a) that faces one side in the radial direction (R). The second rotary member (RT2) has a support inner peripheral surface (51a) that faces an inner side (R1) in the radial direction. A support (41) of the case (4) has a second radial support surface (41a) that faces the first radial support surface (13a). The first bearing (B1) is arranged between the support outer peripheral surface (11a) and the support inner peripheral surface (51a). The second bearing (B2) is arranged between the radial support surfaces (13a, 41a). The first bearing (B1) is arranged on the inner side (R1) in the radial direction with respect to a rotor (Ro) at a position where the first bearing (B 1) overlaps the rotor (Ro) in a radial view.
