PROBLEM TO BE SOLVED: To enhance assembling workability while reducing the manufacturing cost by forming a back cabinet on the wall mounting side through injection molding of polypropylene resin and molding the bearing supporting part integrally with the fan motor supporting part thereby facilitating management of parts in the manufacture. SOLUTION: A back cabinet 2 on the wall mounting side is formed through injection molding of polypropylene resin and respective parts constituting an indoor unit are secured and supported on the wall by an installing plate. Shaft of a cross flow fan 4 is projected from the left end of impeller part and supported by a bearing 5. The bearing 5 is cylindrical and semicircular part thereof is secured to the body of the back cabinet 2 molded into similar shape. The other semicircular part is secured by a bearing supporting part molded simultaneously on the left side of the back cabinet 2. The part 2a between the bearing supporting part and the back cabinet 2 is molded thinner than other part. |
