Abstract: An indoor unit of an air-conditioning apparatus includes a heat-medium heat exchanger, an air vent valve, a drain pan, and a hose. The heat-medium heat exchanger is provided in a housing to cause heat exchange to be performed between a heat medium and indoor air. The air vent valve allows air to escape from a heat medium passage that allows the heat medium to flow in the heat-medium heat exchanger. The drain pan is provided below the heat-medium heat exchanger to receive condensation water generated at a surface of the heat-medium heat exchanger. The hose has flexibility, and is attached to the air vent valve, and provided to let out the air along with the heat medium from the heat medium passage to the inner space in the drain pan. The hose has a double-wall structure and an upper end portion of the hose is fixed to the air vent valve.

Abstract: An indoor unit of an air-conditioning apparatus includes a wind direction vane, a vane motor, an air passage wall, and a shaft joint member. Between a vane shaft and the air passage wall, an annular gap is provided. The shaft joint member includes a flange portion between the air passage wall and the vane motor. The flange portion radially extends outward from a center, thereby causing air that flows toward the vane motor through the annular gap to be diffused outward relative to a direction toward the vane motor.
