<p>PROBLEM TO BE SOLVED: To protect an electric motor in a battery device. SOLUTION: In a casing 6 in which a secondary battery 2, a centrifugal multiblade fan 3 and an electric motor 5 are housed, a barrier member 9 to separate the secondary battery 2 and the centrifugal multiblade fan 3 from the electric motor 5 is placed. Thereby, heat is prevented from being conducted from the secondary battery 2 to the electric motor 5 and dusts sucked from an inlet 7 is prevented from adhering to the electric motor 5. Thus, the electric motor can be protected.</p> |
