INDOOR UNIT FOR AIR CONDITIONER

To provide an indoor unit of an air conditioning apparatus that can reduce the volume of air blown out from any air outlet of plural air outlets while suppressing dew condensation without using a new part. An indoor unit (4) of an air conditioning apparatus (1) that is fixed with respect to a ceiling is equipped with an indoor unit casing (31) that has an air inlet (35) and plural long-side air outlets (51 to 54). Plural flap bodies (80) are disposed in the plural long-side air outlets (51 to 54). The flap bodies (80) can, by rotating, adjust the airflow direction of conditioned air blown out from the long-side air outlets (51 to 54). A control unit (7) can independently adjust the rotational states of the plural flap bodies (80). The control unit (7) causes the entire body of at least any one of the plural flap bodies (80) to be positioned inside the corresponding long-side air outlet (51 to 54) to thereby reduce the volume of the conditioned air passing through the long-side air outlet (51 to 54).
