However, there are various sizes of chambers mounted on the air conditioner main body, and the size in the left-right direction is not always the same as the size of the air conditioner main body. For example, as shown in FIG. 9A, an outlet chamber 140 having a length L2 shorter than the lateral length L1 of the air conditioner main body 120 is provided on the flange portion 121 provided at the outlet of the air conditioner main body 120. The air conditioner 100 to be mounted may be installed in the ceiling space. In this case, as shown in FIG. 9B, when the flange portion 141 of the blowout chamber 140 is attached to the flange portion 121 of the air conditioner main body 120, at least one of both ends in the left-right direction of the blowout chamber 140. The end of the air conditioner does not reach the position of the end of the air conditioner main body 120. Therefore, when the conventional frame frame body is formed with a size capable of supporting the mounting pieces 123 provided on the left and right side surfaces of the air conditioner main body 120, the support bolts for supporting the blowout chamber 140 from the frame frame body are formed. Even if the support bolt is hung down, there is a problem that the lower end portion of the support bolt cannot be connected to the engaging piece 143 attached to the end surface of the blowout chamber 140. The same applies when the intake chamber is attached to the flange portion 131 provided at the intake port of the air conditioner main body 120.

The above problem may occur not only when the chamber is supported by support bolts hanging from the frame body, but also when the chamber is directly supported by hanging bolts attached to a ceiling structure such as a ceiling slab. For example, as shown in FIG. 10, when the ceiling structure 200 on which the air conditioner 100 is suspended has a structure in which the ceiling slab 220 is placed on the upper surface side of the deck plate 210, a plurality of suspension bolts are mounted on the deck plate 210. The 109 is attached, and the air conditioner 100 may be supported in a suspended state by the plurality of hanging bolts 109. Normally, as shown in FIG. 10, the deck plate 210 has a corrugated shape in which peaks 211 and valleys 212 are formed at a predetermined pitch. When attaching the suspension bolt 109 to such a deck plate 210, it is recommended to attach the suspension bolt 109 to the mountain portion 211 in order to prevent a decrease in strength. However, when the lengths of the air conditioner main body 120 and the blowout chamber 140 in the left-right direction are different as described above, the hanging bolts 109 that support the left and right side surfaces of the air conditioner main body 120 are attached to the mountain portion 211 of the deck plate 210. When installed and hung down, it may happen that the hanging bolt 109a supporting the blowout chamber 140 cannot be attached in the vertical direction. In this case, as shown in FIG. 10, the suspension bolt 109a has to be attached in an oblique direction, for example, and has problems such as lowering the support strength and destabilizing the posture of the air conditioner 100.

This problem can occur not only in the left-right direction of the chamber but also in the front-rear direction. For example, as shown in FIG. 11, when the corrugated shape of the deck plate 210 exists in the front-rear direction (Y direction) of the air conditioner 100, the mounting pieces 123 provided on the left and right side surfaces of the air conditioner main body 120 are mounted on the deck. The air conditioner main body 120 is installed in a state of being suspended in the ceiling space by arranging it directly under the mountain portion 211 of the plate 210 and connecting the lower part of the hanging bolt 109 hanging from the mountain portion 211 to the mounting piece 123. To. In this case, the blowout chamber 140 attached to one end of the air conditioner main body 120 is also supported by the suspension bolt 109a attached to the ceiling structure 200. However, it may not be possible to arrange the engaging piece 143 attached to the end surface of the blowout chamber 140 directly below the mountain portion 211 of the deck plate 210. Therefore, as shown in FIG. 11, the suspension bolt 109a that supports the blowout chamber 140 has to be attached in an oblique direction, which lowers the support strength and makes the posture of the air conditioner 100 unstable. Problems arise.

Therefore, the present invention has been made to solve the above-mentioned problems, and is a chamber support metal fitting that can support a chamber mounted on at least one end of the air conditioner main body in the front-rear direction in a properly suspended state. , And an air conditioner support structure is intended to be provided.

Further, when the bolts 23 and 23 are tightened, the end portion of the slide frame 22 is fixed to the fixed frame 21 and is positioned so that it cannot slide. A thin plate-shaped nut arranged inside the double plate structure is attached to the tips of the bolts 23 and 23. Further, a bolt fixing bracket 24 for sandwiching and fixing the support bolt 40 with the surface of the slide frame 22 is attached to the slit 22a. When the bolt attached to the bolt fixing bracket 24 is in the temporarily fixed state, the bolt fixing bracket 24 can slide and move along the slit 22a. Further, when the bolt attached to the bolt fixing bracket 24 is tightened, the bolt fixing bracket 24 is fixed at a predetermined position of the slit 22a, and the support bolt 40 is fixed to the slide frame 22. A thin plate-shaped nut arranged inside the double plate structure is also attached to the tip of the bolt attached to the bolt fixing bracket 24.

The support bolts 40 attached to both ends of the slide frame 22 are for supporting the outlet chamber 140 or the intake chamber 150, and are attached so as to hang down from the slide frame 22. For example, on the rear end surface of the intake chamber 150, engagement pieces 153 that engage with the lower end of the support bolt 40 are attached at at least two positions. The engaging piece 153 is, for example, an L-shaped metal fitting, and the horizontal plate portion is provided with a hole for inserting the support bolt 40, and the vertical plate portion is attached to the end surface of the intake chamber 150. These engaging pieces 153 may be attached to the end surface of the intake chamber 150 by using screws or the like, for example, at the installation site of the air conditioner 100. At that time, the mounting position of the engaging piece 153 is adjusted so as to be a lower position of the slide frame 22.
