PROBLEM TO BE SOLVED: To provide a power source device, wherein even if set at outdoors, a rainwater is prevented from falling to a motor part of a cooling fan in rainy day, while a rainwater which has entered the device is discharged with no residue. SOLUTION: A cooling fan provided below a case, an air duct 7 is provided which has a blow-out opening 25 where an outside air taken in with the cooling fan is supplied to an inverter part, while it is blown toward a fan motor of the cooling fan, and a shielding member (food 16) which blocks rainwater entering the internal side of the air duct of the blow-out opening 25 through an exhaust opening and dropping below the case from blown through the blow- out opening 25 is provided. The air duct 7 is provided with an opening 29A leading to a water-discharge opening formed on the bottom surface side of the case and slopes 26A, 26B, and 26C sloping to the opening 29A. |
