1. A vehicle drive device, comprising:
a rotary electric machine configured to be a drive power source for wheels;
a first power transmission configured to transmit power between the rotary electric machine and the wheels;
a parking assembly;
a case accommodating the rotary electric machine, the parking assembly, and at least a part of the first power transmission; and
a reservoir in the case, the reservoir being configured to store oil, wherein:
the parking assembly includes a parking gear connected to a rotary member of the first power transmission and movable with the wheels, an engagement member selectively engageable with the parking gear, and a second power transmission configured to transmit power to the engagement member,
the parking gear is coaxial with the rotary electric machine,
the reservoir and the second power transmission are located above a portion of the first power transmission,
an area of the reservoir in a front-rear direction, an area of the first power transmission in the front-rear direction, and an area of the second power transmission in the front-rear direction overlap an area of the rotary electric machine in the front-rear direction, where the front-rear direction is a direction perpendicular to an axial direction of the rotary electric machine when viewed in a vertical direction, and
the reservoir is above the parking gear and overlaps the second power transmission when viewed in the front-rear direction.
