Reference numeral 15 denotes a soundproof housing attached so as to cover the compressor 16, and is provided on the bottom plate 17 of the main body case of the outdoor unit 10.

  The soundproof housing 15 includes a front plate 151, a left front plate 152, a left rear plate 153, a front top plate 154, a rear top plate 155, a back plate 156, a right rear plate 157, and a right front plate 158. A sound absorbing material 159 such as CR rubber or porous material is attached to the inner wall. The left front side plate 152 and the left rear side plate 153 constitute a left side plate, the front top plate 154 and the rear top plate 155 constitute a top plate, and the right rear side plate 157 and the right front side plate 158 constitute a right side plate. The left rear plate 153, the right rear plate 157, and the back plate 156 may be individually formed of sheet metal or may be formed by bending a single sheet metal.

  The rear top plate 155 has a plurality of notches 155a formed on the front side thereof through which pipes and the like connected to the compressor 15 are inserted, that is, to escape from the pipes 31 and the wiring. A plurality of through holes 155b for allowing only the wiring to pass therethrough are also formed (FIG. 3).

  As shown in FIG. 4, the right rear side plate 157 has cut and raised claws 157a and 157b formed by cutting and bending at the upper and lower positions of the front edge, and the rear edge portion of the right front side plate 158 has the cut and raised claws 157a, It can be slidably attached to and detached from 157b in parallel to the right rear plate 157, that is, in the front-back direction.

  The right front plate 158 is formed with a notch 158a at the lower back corner portion, and the rear edge of the right front plate 158 is fitted into the cut and raised claws 157a and 157b of the right rear plate 157, thereby removing the notch. A notch hole 18 is formed between 158a and the lower part of the front edge of the right rear plate 157.

  A mounting leg 161 is attached to the lower portion of the compressor 16 so as to project to the periphery. As shown in FIG. 2, the mounting leg 161 is screwed to the bottom plate 17 of the main body case via a vibration-proof rubber 19. It is supported.

  Now, the left front side plate 152, the left rear side plate 153, the rear top plate 155, the back plate 156, and the right rear side plate 157 of the soundproof casing 15 of this embodiment are fastened by screws and assembled on the bottom plate 17 of the main body case. As shown in FIG. 5, the right front side plate 158 is fitted to the cut and raised claws 157 a and 157 b of the right rear side plate 157 at the rear edge thereof.
