<p>It is intended in an air-conditioning indoor unit to enhance airtightness of a hollow structure of an airflow direction adjustment louver and prevent expansion and shrinkage of the airflow direction adjustment louver itself. In the air-conditioning indoor unit (10), air movement is enabled between inside and outside of the airflow direction adjustment louver (31) only through a vent hole (312). Moreover, the vent hole (312) does not exist in a pathway of blown air. Hence, it is avoided that cold air blown out in a cooling operation intrudes into the airflow direction adjustment louver through the vent hole.</p> |
