- Auxiliary wind direction plate 111 has lower surface 111b facing first vertical wind direction deflecting plate 109, and upper surface 111a located opposite to lower surface 111b.
- Auxiliary wind direction plate 111 has first and second ends in a left-right direction from the left wall surface toward the right wall surface.
- First and second longitudinal blades 112 are erected near the first end and the second end of upper surface 111a of auxiliary wind direction plate 111, respectively.
- Both first and second longitudinal blades 112 are disposed between the left and right side walls of air outlet 102. First and second longitudinal blades 112 may be disposed closer to the center in the left-right direction of the indoor unit.

- First longitudinal blade 112 is located closer to the right side wall of air outlet 102 than second longitudinal blade 112.
- Second longitudinal blade 112 is located closer to the left side wall of air outlet 102 than first longitudinal blade 112.
- the distance between first longitudinal blade 112 and the right side wall is desirably less than 5 mm.
- the distance between second longitudinal blade 112 and the left side wall is desirably less than 5 mm.
- first vertical wind direction deflecting plate 109 is rotated, and upper surface 111a of auxiliary wind direction plate 111 is exposed to the indoor space.
- the indoor air is induced by the blown air flow blown into the room from air outlet 102, and flows such that the indoor air on the side of air outlet 102 is sucked into the vicinity of upper surface 111a of auxiliary wind direction plate 111.
- Auxiliary wind direction plate 111 is constantly exposed to the cold air blown out from air outlet 102 to have a low temperature.
- Low-temperature auxiliary wind direction plate 111 can cause dew condensation in an environment with high humidity of indoor air.
- air conditioner 100 includes first and second longitudinal blades 112 on upper surface 111a of auxiliary wind direction plate 111.
- First and second longitudinal blades 112 are disposed at the first and second ends of upper surface 111a, respectively.
- First and second longitudinal blades 112 suppress suction of indoor air from the side of air outlet 102 into upper surface 111a of auxiliary wind direction plate 111. This configuration can reduce the risk of dew condensation on upper surface 111a of auxiliary wind direction plate 111 in an environment with high humidity of indoor air.
- first and second longitudinal blades 112 are disposed between the left side wall and the right side wall of air outlet 102, respectively.
