That is, the arm main body 80 integrally turns around the axis O with the shaft portion 81.
  • the inlet panel 9 is a panel capable of shifting between a state of covering the front surface 51 of the front panel 50 from the foreside Dif and a state of not covering the front surface 51 in response to turning of the arms 8 around the axis O.
  • the inlet panel 9 is connected to the other end of each of the arm main bodies 80.
  • the end edge of the inlet panel 9 on the upside Dvu becomes a top edge 9a.
  • the top edge 9a of the inlet panel 9 is positioned below the top edge 1a of the casing 1 when the inlet panel 9 is positioned at the closed position.
  • the casing 1 opens on the front surface 51, and the holder accommodation portions 52 recessed toward the upside Dvu as they go toward the backside Dib are provided. Further, the arm holders 6 respectively inserted into the holder accommodation portions 52 are fixed to the insides of the holder accommodation portions 52 in an attachable/detachable manner.
  • the arms 8 turnably held by the arm holders 6 turn in a manner of being able to move between the closed position where the front surface 51 is covered such that the inlet panel 9 covers the openings 50a of the holder accommodation portions 52 and the open position where the inlet panel 9 has moved forward and upward from the closed position and the front surface 51 has opened.
  • the arms 8 extending from the arm holders 6 to the inlet panel 9 can be positioned farther to the downside Dvd. That is, the openings 50a of the holder accommodation portions 52 can be positioned farther to the downside Dvd.
  • the inlet panel 9 when the inlet panel 9 is positioned at the closed position where the front surface 51 side is covered, the inlet panel 9 can completely cover the openings 50a of the holder accommodation portions 52 from the front side. Namely, a good appearance when the inlet panel 9 is closed is not impaired.
  • the arm holders 6 are attached and detached inside the holder accommodation portions 52, the arms 8 held by these arm holders 6 and the inlet panel 9 fixed to these arms 8 can be attached and detached with respect to the casing 1 at the same time. Therefore, the arms 8 are easily attached and detached with respect to the casing 1.
  • the indoor unit 100 of the embodiment when the inlet panel 9 is positioned at the closed position, the top edge 9a of the inlet panel 9 is positioned below the top edge 1a of the casing 1.
  • the inlet panel 9 can be made compact and reduced in weight.
  • the arm holders 6 can be fixed to the casing 1 using simple members such as bolts 7. Therefore, it is possible to curb increase in costs and man ⁇ hour related to manufacturing of the indoor unit 100.
  • the indoor unit 100 of the embodiment in a condition where the holding portions 60 of the arm holders 6 are inserted into the holder accommodation portions 52, the second engagement portions 61 of the holder accommodation portions 52 are engaged with the first engagement portions 521 of the arm holders 6. Accordingly, since the holding portions 60 stand still on the support surfaces 520d, work of fixing the fixed portions 62 to the holder support portions 520 using the bolts 7 becomes easy.
  • the holding portions 60 in the arm holders 6 respectively have the guide portions 602 guiding the shaft portions 81 of the arms 8 which have been inserted into the holder accommodation portions 52 to the bearing portions 603. Therefore, the arms 8 fixed to the insides of the holder accommodation portions 52 can be simply attached to the arm holders 6.
  • the bearing portions 603 are positioned on the upside Dvu of the openings 50a of the holder accommodation portions 52. That is, the shaft portions 81 of the arms 8 can be rotatably held by the arm holders 6 on the upside Dvu of the openings 50a. Accordingly, a structure which is difficult to be directly formed in the casing 1 can be realized by the arm holders 6.
  • first engagement portion 521 is formed of a material having flexibility
  • first engagement portion 521 may not be formed of a material having flexibility
  • second engagement portion 61 in place of the first engagement portion 521, may be formed of a material having flexibility
  • both the first engagement portion 521 and the second engagement portion 61 may be formed of a material having flexibility.
