  Thereby, each side panel 300,400 is temporarily fixed on the base panel 100 via the holding means, and does not fall outside even if the hand is released. Next, the front panel 500 is attached. When attaching the front panel 500, first, the front panel 500 is held in the hand and fitted into the opening between the side panels 300 and 400.

  If the position of the front panel 500 in the width direction is shifted at this time, the guide ribs 530 and 540 hit the end portions of the side panels 300 and 400, and guide the front panel 2500 to the correct position along the tapered surfaces 531 and 541.

  When it is confirmed that the positions in the width direction are matched, the operator inserts the locking claws 520 of the front panel 500 along the locking holes 330 and 430 of the side panels 300 and 400. After confirming that all the locking claws 520 have entered the locking holes 330 and 430, the locking claw 520 is moved into the locking holes 330 and 430 by sliding the front panel 500 slightly downward. Be hooked.

  After the front panel 500 is hooked and fixed to the side panels 300 and 400, the nipping portion 160 of the motor mounting base 130 is next viewed from above with respect to the nipping surface 550 of the front panel 500, as shown in FIG. Attach and sandwich.

  Finally, the ceiling panel 600 is attached. The ceiling panel 600 is placed so as to cover the upper ends of the side panels 300 and 400 and the front panel 500. At this time, the mounting position can be easily determined by the guide ribs 350 and 440 provided at the upper ends of the side panels 300 and 400.

  At this time, the reinforcing piece 610 of the ceiling panel 600 is inserted along the insertion groove 560 of the front panel 500. Thereby, the front panel 500 is completely fixed. Finally, screw holes (not shown) provided in the ceiling panel 600 and screw holes (not shown) of the side panels 300 and 400 are aligned and screwed. The outdoor unit main body 100 is completed by the series of steps described above.

  In addition, since it is an arbitrary matter in this invention about the connection of a refrigerant pipe and various cables for functioning the outdoor unit main body 100, the description is abbreviate | omitted.
