PROBLEM TO BE SOLVED: To effectively cool a power drive unit, in an electric vehicle having a pair of electric motors for exhibiting power for driving drive wheels and a pair of power drive units individually corresponding to those electric motors.SOLUTION: In the electric vehicle, a pair of power drive units 68 are arranged in parallel with each other, and heat sinks 69 each having a plurality of cooling fins 69a extending in parallel in a direction orthogonal to the parallel direction of those power drive units 68 are individually attached to the mutually opposed sides of the pair of power drive units 68 respectively. A pair of air guide passages 87 for individually storing the heat sinks 69 is formed so that cooling air can circulate in the extension direction of the cooling fins 69a, between a partition wall part 85a which is integrally formed with an air guide member 85 for closing a space between the pair of power drive units 68 on both ends along the parallel direction and is arranged between the pair of heat sinks 69, and the pair of power drive units 68. |
