PURPOSE:To prevent the dropping of a main frame by a method wherein a pro-. jected part of main frame side is hooked by a projected rib of a retaining plate side when the ceiling surface of the main frame of an air-conditioning machine is broken. CONSTITUTION:A retaining plate 7, provided on an installation plate 2, is provided with an integrally formed L-shape rib (projected rib of retaining plate side) 14 in a direction that the tip end of the L-shape is faced upward. Another L-shape rib (main frame side projected rib) 15, formed integrally with the main frame 1 of the air-conditioning machine and projected from the back surface of the main frame 1 of the air-conditioning machine above said L-shape rib 14 so as to be hooked to the L-shape rib 14, is provided in a direction that the tip end of L-shape is faced downward. When the ceiling surface of the main frame 1 of the air-conditioning machine is broken, the main frame side projected rib 15 is hooked to the retaining plate side projected rib 14. According to this method, the dropping of the main frame 1 of the air-conditioning machine can be prevented. |
