<p>To prevent corrosion of a bracket made of aluminum for attaching a heat exchanger made of aluminum. A bracket (40) made of aluminum is cooperatively fastened by a male screw (80) made of iron and an attachment plate (70) made of iron and is fixed to a blower chamber-side side panel (23) made of sheet steel. The outer diameter of the male screw (80) is smaller than the dimension of a through hole (43a) in the bracket (40). The bracket (40) made of aluminum is fastened via a resin cover (60) to the blower chamber-side side panel (23), and the bracket (40) made of aluminum is maintained by the resin cover (60) in a non-contact state in which the bracket (40) also does not contact the male screw (80) made of iron passing through the through hole (43a) in an attachment piece (43).</p> |
