This makes it possible to reduce the manufacturing costs of the indoor unit 100 while eliminating the need for jigs on the manufacturing line.
  • the wiring 20 connected to the terminal block 5 can be temporarily fixed to the component cushioning material 16, eliminating the need for jigs on the manufacturing line and reducing the manufacturing costs of the indoor unit 100.
  • the parts cushioning material 16 has a cutout shape 22 formed therein, which prevents interference with the driver 21 when attaching the rear sheet metal part 19 to the indoor unit 100 during the manufacturing process. This means that the parts cushioning material 16 does not get in the way of line assembly, preventing a deterioration in workability.
