PURPOSE:To ensure the strength of an indoor side diffuser and to avoid dew on electric components by mounting reinforcing materials at both surfaces of a heat insulator under the diffuser. CONSTITUTION:A lower surface 1a of an indoor side diffuser is, for example, formed of foamed styrol, and has two parallel hooklike grooves 2 in a longitudinal direction. An upper plate 3 is inserted from its front side while engaging a hook like rib 4 with the groove 2. A wind direction deflecting plate 6 is mounted under a lower plate 5, a shaft 7 of a motor 6 is passed through holes 8 provided at the plates 3, 5, extended to the diffuser 1, and an end of the shaft 7 is pressed into a shaft 9 of blades. Since the plates 3, 5 are disposed as reinforcing plates above and below the surface 1a of the diffuser 1 having insufficient strength, the strength of a periphery of the hole 8 is ensured. Thus, the strength of the diffuser 1 can be obtained, and dew on electric components such as a wind direction deflecting motor 6 can be avoided. |
