  • stepped drive arm 19 is slidably supported by guide 24.
  • the air conditioner When the air conditioning operation is started, the air conditioner according to the present exemplary embodiment opens vertical wind direction change blades 6, 7 to open air outlet 3.
  • fan 5 When fan 5 is driven in this state, the indoor air is taken into the inside of the indoor unit through air inlet 2.
  • the taken indoor air is subjected to heat exchange by the heat exchanger, passes through fan 5, passes through wind circuit 4, and is blown out from air outlet 3.
  • the direction of the air blown out from air outlet 3 is changed by vertical wind direction change blades 6, 7 and left-right wind direction change blade mechanisms 8, 9 to cool or heat the room.
