To improve heat dissipation of an electric motor.SOLUTION: An electric drive type work vehicle comprises a vehicle body frame, a body, a pair of left and right wheels, and an electric drive type travel device for driving the pair of left and right wheels, in which the electric drive type travel device comprises a first electric motor, a second electric motor, a rear axle, and a motor cooler. The motor cooler comprises: a duct which is communicated with a midship part in an axial direction of the rear axle; a blower for flowing air to the duct; a first wind guide which changes a flow direction of a part of air, which flows to the first electric motor, of air flown into the rear axle from an outlet of the duct, and guides the same to a first specific part of the first electric motor; and a second wind guide which changes a flow direction of a part of air, which flows to the second electric motor, of air flown into the rear axle from the outlet of the duct, and guides the same to a second specific part of the second electric motor.SELECTED DRAWING: Figure 4
