A non-aluminum metal side plate and an aluminum or aluminum alloy bracket for attaching an aluminum or aluminum alloy heat exchanger are secured, and corrosion of the aluminum or aluminum alloy bracket is prevented. The attachment piece (53) of an aluminum bracket (50) is secured to a steel side plate (23) on the side of an air blower chamber. The steel side plate (23) on the side of the air blower chamber has an opening (233g) through which the attachment piece (53) of the aluminum bracket (50) penetrates. The attachment piece (53) of the aluminum bracket (50) is secured by penetrating the opening (233g). A resin cover (60) is disposed between the aluminum bracket (50) and the steel side plate (23) on the side of the air blower chamber and forms a predetermined space between the aluminum bracket (50) and the steel side plate (23) on the side of the air blower chamber. |
