<P>PROBLEM TO BE SOLVED: To provide an air conditioner which is an air conditioning device equipped with an automatic filter cleaning mechanism, and prevents engaged two racks and gears from being displaced when a filter is mounted. <P>SOLUTION: In an indoor unit of the air conditioner, a filter 21 can be attached to and detached from a frame of a filter cleaning part. The filter 21 has a first gear 211 and a second gear 212, which engage with a pinion 31.The first gear 211 and second gear 212 are located at a predetermined distance from each other in a width direction crossing a movement direction of the filter 21. The ratio of a pitch P of peaks 21m of the first gear 211 and second gear 212 to the predetermined distance is 0.020-0.050. If an engagement position between the second gear 212 and pinion 31 is displaced from an engagement position between the first gear 211 and pinion 31, the filter 21 is in an unnatural posture and repulsion increases owing to deformation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
