Zusammenfassung:	In an electrically driven vehicle which has a pair of electric motors for generating motive power to operate a driving wheel, and a pair of power drive units provided individually corresponding to these electric motors, the power drive units are to be effectively cooled. [Means for solving the object] The pair of power drive units 68 extend in parallel. A pair of heat sinks 69 which have a plurality of cooling fins 69a extending in parallel with the direction orthogonal to the parallel extending direction of the power drive units 68 are attached individually to lateral surfaces on mutually opposed sides of the pair of power drive units 68 respectively. A partition wall section 85a formed integral with a baffle member 85 which closes a space between the pair of power drive units 68 at both ends in the parallel extending direction, is arranged between the pair of heat sinks 69. A pair of air guide passages 87 which house the heat sinks (69) individually therein so as to circulate cooling air in the extending direction of the cooling fins 69a, are formed between the partition wall section (85a) and the pair of power drive units (68).
