In each of the drawings, the air conditioning chamber 1 according to the present embodiment communicates with the supply duct 4 connected to the inlet side opening 2a of the chamber body 2 and the outlet, as in the first embodiment. A flexible duct 5 is connected to and communicates with the side opening 2b. On the other hand, as a different point, instead of the substantially V-shaped air volume adjusting body 3, a plurality of inclined guide vanes are disposed in the chamber body 2. It has the structure provided with the plate-shaped air volume adjustment body 6 formed by 6a.

The body 6 is disposed so as to be positioned between the outlet side openings 2b on the left and right side walls of the chamber body 2 and adjusted to the guide vanes 6a of the air volume adjusting bodies 6 to the outlet side openings 2b. Air distribution can be made uniform.
[0035]
Moreover, in the air conditioning chamber according to the above-described embodiment, the air volume adjusting body 6 is arranged at a substantially central position in the chamber body 2, but the number of outlet side openings 2 b in the chamber body 2 is reduced. In this case, as shown in FIG. 6, the air volume adjusting body 6 may be disposed on the left and right side walls of the chamber body 2 so as to be positioned on the front side of each outlet-side opening 2 b, and is positioned in front of the inlet-side opening 2 a. The guide vanes 6a of the air volume adjusting body 6 to block the straight movement of the airflow flowing into the chamber body 2, so that the dynamic pressure of the airflow does not reach the outlet side opening 2b at the inner end of the chamber body 2 as it is, and the inlet The airflow can be evenly distributed to the outlet-side opening 2b of each side wall so that the airflow can be evenly distributed so that the airflow is directed to the outlet-side opening 2b on the side close to the side opening 2a.
[0036]
Furthermore, in the air conditioning chamber according to the above-described embodiment, the guide vanes 6a of the air volume adjusting body 6 are arranged to be inclined symmetrically, but in addition, the inclination angle of each guide vane 6a is appropriately set. The air volume balance to each outlet side opening 2b in the chamber body 2 can be adjusted by adjusting the inclination angle of each guide blade 6a, and the air volume distributed to each outlet side opening 2b can be adjusted downstream. The distribution can be optimized by finely adjusting in accordance with the difference in air conditioning conditions on the side. Further, by adjusting the inclination angle of each guide vane 6a, the distribution can be equalized even when the arrangement and number of outlet openings 2b and flexible ducts 5 are changed, but conversely, the outlet openings 2b are different. Even when the air volume is required, the necessary air volume can be appropriately distributed to each outlet side opening 2b by adjusting each guide blade 6a.
