Therefore, if the duct port side of the air blowing duct 150 can be once lifted up, the duct port side can be temporarily fitted by the hook members 156 while floated, and the connecting work of the air blowing duct 150 can be facilitated.
  • the heat insulating cushion member 157 is formed of a heat insulating member having cushion property to be embedded in the gap between the air blowing duct 150 and the unit main body 110, and it is formed of polyethylene, for example, By inserting the heat insulating cushion member 157 between the air blowing duct 150 and the unit main body 110, the gap between the air blowing duct 150 and the unit main body 110 can be perfectly shielded and also sufficient heat insulation can be performed.
  • the air flow amount to be supplied to the air blowing duct 150 can be set to a small value, and thus the distribution rate of the air-conditioned air supplied to the air blowing duct 150 and the air blowing port 122 of the face panel 120 can be set to be larger at the air blowing port 122 side.
  • the opening area of the duct port D0 is set to be larger than the case of Fig. 14, and thus the air flow amount to be supplied to the air blowing duct 150 can be increased. Therefore, the distribution rate of the air-conditioned air supplied to the air blowing duct 150 and the air blowing port 122 of the face panel 120 can be set to be larger at the air blowing duct 150 side.
  • the knockout holes 160 located along the edge portions of the plural duct-planed ports D1 to D4 are formed in the housing 111 so as to be spaced from one another, and the duct-planed ports D1 to D4 are selectively opened and set to the duct port D0. Therefore, the air flow amount supplied to the air blowing duct 150 can be adjusted, and the distribution rate of the air-conditioned air supplied to the air blowing duct 150 and the air blowing port 122 of the face panel 120 can be freely adjusted. Furthermore, when the duct port D0 is formed, it is sufficient only to selectively cut out the knockout holes 160 formed in the housing 111 .
  • the air conditioner 100 may be designed so that when the air blowing duct 150 is connected, the air conditioner, the air blowing port 122 of the face panel 120 is closed by a closing member and the air-conditioned air is blown from only the air blowing duct 150.
  • the pocket portion 99 is constructed as the hermetically accommodating portion for accommodating the portion exposed to the side panel 19A side of the screw 80B as a fixing member while the portion concerned is substantially hermetically sealed.
  • the head portion of the screw is located in a recess portion, the recess portion concerned is sealed by a lid member so that the lid member is detachable from the recess portion, and the hermetically accommodating portion is constructed by the recess portion and the lid member.
  • the shape of the pocket portion 99 is not limited to the box-shape like this embodiment, but various shapes such as a cylindrical shape, etc. may be applied.
  • the knockout holes 160 which can easily open the four duct-planed ports D1 to D4 arranged in the two vertical columns and two lateral lines are formed in the unit main body 110 in advance.
  • the number and shape of the duct-planed ports may be arbitrary.
  • knockout holes corresponding to duct-planed ports D1 to D4 arranged four lateral lines which are symmetrical with respect to the right and left sides may be formed as shown in Fig. 16.
  • the duct-planed ports D2 and D3 may be set to the duct port D0, and when the air blowing amount is increased, all the duct-planed ports D1 to D4 may be opened and set to the duct port D0.
  • the shape of the knockout holes is not limited to the slender hole shape, and various hole shapes such as a round hole, etc. may be applied.
