A work vehicle includes a transmission case including an electric transmission chamber and a gear transmission chamber located rearward of the electric transmission chamber, the gear transmission chamber and the electric transmission chamber being partitioned from each other. A front transmission shaft extends frontward from the gear transmission chamber to transmit motive power to a front travel device. The transmission case includes a tube providing a power transmission path that passes through the electric transmission chamber in the front-rear direction while being partitioned from the electric transmission chamber. The front transmission shaft passes through the power transmission path.

A unit includes a heat exchanger; a motor case configured to accommodate a motor; and an inverter case configured to accommodate an inverter, wherein the inverter case has a portion that overlaps the heat exchanger and the motor case when viewed in a predetermined direction.

Provided is a unit including: a housing configured to accommodate a planetary gear mechanism, in which the housing includes a flow path through which a coolant flows, the planetary gear mechanism includes a ring gear fixed to the housing, and the flow path has a portion that overlaps the ring gear when viewed in a radial direction.
