<P>PROBLEM TO BE SOLVED: To enable vehicular aerodynamic characteristics to be effectively improved with a simple structure by making traveling wind that passes below the vehicle flow smoothly. <P>SOLUTION: In a control structure of vehicular aerodynamic characteristics having an under-floor under cover 5 provided below the floor surface of the vehicle, the under-floor under cover 5 has inside cover sections 14 of approximately a flat surface shape provided over a space between front wheels and rear wheels and at a position lower than the lower end of side sills 13 and outside cover sections 15 arranged between the inside cover sections 14 and the side sills 13. Level difference sections having upper wall plates 17 located above the setting height of the inside cover sections 14 are provided on the outside cover sections 15, and openings 20 for work are formed so as to face predetermined positions of the lower ends of side sills in a bottom surface view. <P>COPYRIGHT: (C)2012,JPO&INPIT |
