摘要： A work vehicle is provided in which driving force is generated by an engine or the like and by an electric motor, and in which heat generated by the engine cannot easily be transmitted to an inverter and to a capacitor. This work vehicle includes a vehicle body frame, an outer cover, an engine compartment, a cooling compartment, a partition wall, an inverter, and a capacitor. The engine compartment contains an engine. The cooling compartment contains a cooling device. The partition wall separates the cooling compartment from the engine compartment. The inverter and the capacitor are disposed between the partition wall and the cooling device. The inverter is positioned above the capacitor. A length of the capacitor in the vehicle width direction is greater than a length of the inverter in the vehicle width direction. At least one of a first side surface of the outer cover positioned leftwards of the left side surface of the inverter and a second side surface of the outer cover positioned rightwards of a right side surface of the inverter is separated from the inverter by a gap.
