PROBLEM TO BE SOLVED: To cool the electric motor 12 of a blower 10 by air blown out from a fan 11 without adding components composing a casing 20.SOLUTION: A duct case 40 has a cooling air path 42 passing the air taken in from the air intake port 41 through a space between a scroll casing 26 and a heat exchanger 50 for cooling to circulate it to the vehicle rear side of the heat exchanger 50. The duct case 40 and a sidewall 23 are integrally molded by injection molding. A motor flange 43 supports an electric motor 12, and has an air path 45 circulating the air passing through the cooling air path 42 to the side of the electric motor 12. The electric motor 12 is cooled by the air blown out from a blowout port 33 using the duct case 40 molded integrally with the sidewall 23 of the scroll casing 26. |
