PURPOSE:To prevent a curved air filter from being finely vibrated during operation of an air conditioner by a method wherein an air filter has resiliency repelling form a guide member and a main body is formed with a pushing member for restricting a warp in the air filter. CONSTITUTION:A curvature R1 of a filter guide surface 32 of a guide member 18 is set smaller than a curvature R2 of the inner surface 33 of a prefilter 7. Accordingly, under a condition in which the prefilter 7 is merely abutted against the guide member 18, the prefilter 7 is point contacted with the guide member 18 and warped away from the guide member 18. However, an upper end 24 of the prefilter 7 is pushed against the guide member 18 by the pushing part 28 of the front cover 3 and the lower end of the prefilter 7 is inserted into a fixing hole 27 of the guide member 18. With such an arrangement, the prefilter 7 is pushed wide in an upward direction of the guide member 18 with the resilient force of the filter and fixed to the guide member 18. Accordingly, even if a vibration during operation of a blower 12 is transmitted to the prefilter 7, the fine vibration is prevented from being generated and the vibrating sound is prevented from being generated. |
