<P>PROBLEM TO BE SOLVED: To provide an inlet structure of an electric storage box which can prevent intrusion of water without increasing pressure loss. <P>SOLUTION: In the structure of an inlet 5 provided, in the side wall of an electric storage box adapted to air-cool the internal electric components by utilizing the outside air 6, to communicate with an intake duct 7 extending along the side wall in the electric storage box, a plurality of rows of louvers 10 are arranged while inclining reversely to the intake direction of the outside air 6 so as to shield the inlet 5. The stretching height of each louver 10 into the intake duct 7 for the opening surface of the inlet 5 is lowered gradually in the intake direction of the outside air 6. <P>COPYRIGHT: (C)2012,JPO&INPIT |
