    摘要： An electric work vehicle includes a vehicle body having traveling wheels, a traveling motor capable of driving the traveling wheels, and a battery unit having, at one end portion thereof, a pair of left and right leg wheels, the battery unit being detachably attachable to a battery storage section of the vehicle body and being capable of supplying electric power to the traveling motor. The battery unit, when detached from the battery storage section, is posture-switchable between a flat placement state in which the leg wheels and the other end portion thereof opposite to the side on which the leg wheels are located are placed in contact with the ground surface and a tilted posture in which the battery unit can stand on its own with the other end portion thereof being located higher than the leg wheels.
