PURPOSE:To prevent the pollution of the electrical equipment by providing a partition isolating the lower section and upper section of a space formed inside a vehicle body casing, arranging a blower on the partition to generate an air stream flowing from the upper section of the space to the lower section, and discharging the gas and mist generated by overcharged batteries to the outside. CONSTITUTION:When a blower 21 is rotated, an air stream F flowing from an upper space A to a lower space B is generated, and the heat generated by the electrical equipment 15 is discharged from the upper space A to the lower space B. When batteries 16, 17 are overcharged during an automatic charge and gas and mist are generated, they are interrupted by a partition 20 and do not rise to the upper space A and are accumulated between the batteries 16, 17. When the air stream F is generated, the air above the batteries 16, 17 flows toward the air stream F to generate a stream (f), and the gas and mist accumulated above the batteries 16, 17 flow to the lower section of the lower space B together with the air stream (f) and are diffused to the outside of a vehicle body casing 10. |
