<p>PROBLEM TO BE SOLVED: To improve cooling performance of a water-proof type electric apparatus.SOLUTION: A housing 14 is partitioned into a first chamber 24 and a second chamber 26 which are partitioned by a partition member 20. The first chamber 24 is partitioned into a water stop region 30 and an outside communication region 32 by a seal member. Air is sent from an intake hole 50 into a ventilation path 48 by driving of a fan disposed in the outside communication region 32, so that wind is made to flow into the second chamber 26 to cool a heating component disposed in the water stop region 30.</p> |
