[0031]
When mounting the panel portions 5 and 5a, the installation error and the distortion of the panel portion 5 can be removed by the clearance between the mounting hole of the frame portion 4 and the stud bolt 10 and the cushioning material 9. When the stud bolt 10 facing the frame portion 4 is fixed to the panel portion 5 located outside the frame portion 4 and the panel portion 5a is located inside the frame portion 4, the panel portion 5a is located inside the frame portion 4. Since the stud bolts 10 facing the side are fixed, the bolts and nuts are not formed on the outside of the panel portion 5. Next, the door 6 is attached to the panel section 5 via a manual engagement device.
[0032]
At the time of maintenance / inspection, the door 6 is removed, the operator gets into the air conditioner 1, and only the panel portion 5a located inside the frame portion 4 required for maintenance / inspection is removed. Since the triangular panel 7 is attached to the frame 4 via the hinge 11, the triangular panel 7 can be opened and closed without being removed from the frame 4.
[0033]
The panel sections 5 and 5a, the door 6, and the triangular panel section 7 are made of a vibration damping material. Therefore, when the elevator car 2 travels, wind noise caused by wind pressure is suppressed.

[0034]
As described above, according to the present embodiment, the air conditioner 1 has the frame portion 4, the panel portions 5 and 5a having the door 6, and the triangular panel portion 7, each having a divided structure. Since each member is small and light and easy to carry and change direction, the installation of the air conditioner 1 is improved. Furthermore, since the frame part 4 of the air conditioner 1 has a framed structure, it is difficult for extra force to be applied to the panel parts 5, 5a, and the constituent members 4, 5, 5a, 6, 7 can be divided freely. Adjustment of the mounting error is facilitated and workability is improved.
[0035]
Further, since the frame part 4 of the air conditioner 1 has a frame structure, it is possible to partially remove any of the panel parts 5 and 5a, and the maintenance work of the elevator car 2 is improved. Further, since the panel portion 5a inside the frame portion 4 to be removed at the time of maintenance and inspection is configured to be attached by the stud bolt 10 provided inside the frame portion 4, when the panel portion 5a is removed, the panel portion 5a moves up and down.

Further, in the work, since the worker does not go out of the air conditioner 1 and remove the bolt, the work safety is also improved.
[0038]
Further, since the panel portions 5 and 5a are made of a vibration damping material and further provided with the sound absorbing material 8, wind noise around the air conditioner 1 generated when the elevator car 2 travels is reduced. The sound is hardly propagated into the room 2a, and noise generated in the air conditioner 1 is also absorbed by the sound absorbing material 8. Therefore, it does not cause discomfort to elevator users. Further, since the panel portions 5 and 5a have a divided structure, the workability of mounting the sound absorbing material 8 is also improved.
