To fix a bracket made of aluminum or aluminum alloy for attaching a heat exchanger made of aluminum or aluminum alloy and a side panel made of a non-aluminum metal and to prevent corrosion of the bracket made of aluminum or aluminum alloy. An attachment piece (53) of a bracket (50) made of aluminum is fixed to a blower chamber-side side panel (23) made of sheet steel. The blower chamber-side side panel (23) made of sheet steel has an opening portion (233g) through which the attachment piece (53) of the bracket (50) made of aluminum passes. The attachment piece (53) of the bracket (50) made of aluminum passes through the opening portion (23 3 g) and is fixed. A resin cover (60) is interposed between the bracket (50) made of aluminum and the blower chamber-side side panel (23) made of sheet steel and forms a predetermined space between them. |
