1. A vehicle drive device comprising:
a rotary electric machine disposed on a first axis;
a transmission mechanism to which drive force from the rotary electric machine is transmitted;
a differential gear mechanism that is disposed on a second axis that is a separate axis parallel to the first axis and that distributes the drive force from the rotary electric machine via the transmission mechanism to a wheel;
an output member that is disposed on the second axis and that drivingly connects the differential gear mechanism and the wheel;
an inverter device for driving and controlling the rotary electric machine;
a terminal block for electrically connecting a rotary electric machine-side bus bar connected to a stator coil of the rotary electric machine and an inverter-side bus bar connected to the inverter device; and
a case integrally formed with a first housing chamber for housing the rotary electric machine and a second housing chamber for housing the inverter device, wherein
the integrally formed case includes a partition wall for separating the first housing chamber and the second housing chamber,
the terminal block is disposed such that an arrangement area of the terminal block in an axial direction that is a direction along the first axis overlaps the rotary electric machine, and disposed so as to penetrate the partition wall in a radial direction of the output member, and
the partition wall and the terminal block are disposed between the inverter device and the second axis in an up-down direction.
