PROBLEM TO BE SOLVED: To prevent dust and water contained in cooling air from adhering to electronic parts and terminals stored in an electrobox. SOLUTION: The main body 26 of an electrobox 10 is of a double structure having an outer box part 28 and an inner box part 30, and an electronic control circuit 44 is stored in a ventilating box 48 in the inner box part 30. A seal packing 52 is disposed between the inner box part 30 and the ventilating box 48, and an air duct 54 is formed between the inner box part 30 and the ventilating box 48. A cooling air inlet 56 and a cooling air outlet 58 are formed in the air duct 54. The outer box part 28 is closed by a cover 60, and a seal packing 64 is disposed between the outer box part 28 and the cover 60. Accordingly, the outside air in an engine room and cooling air flowing in the air duct are kept from flowing into the ventilating box 48. |
