<P>PROBLEM TO BE SOLVED: To provide an underfloor structure of an electric vehicle which can improve aerodynamic performance as a whole vehicle by suppressing increase in air resistance while preventing a battery unit disposed in the underfloor from wetting. <P>SOLUTION: In the underfloor structure of the electric vehicle EV, wherein a battery unit 16 disposed in the underfloor of the vehicle is covered with under covers 4, 5, 6 the battery under covers 4, 5, 6 include a motor room rear under cover 4 which covers a front extended region from a first battery under cover 5 and includes water draining means D1, D1 and D2. The draining means D1, D1 and D2 include a front side inclined wall 21 having drain ports 42, 43, 44 opened and a rear side inclined wall 22 having a traveling wind flow rectifying surface 25. A dent shape in a longitudinal direction of the vehicle from the motor room rear under cover 4 is formed such that a first interior angle θ1 by the front side inclined wall 21 is made larger than a second interior angle θ2 formed by the rear side inclined wall 22 and the lengths of two wall surface are made different. <P>COPYRIGHT: (C)2012,JPO&INPIT |
