When the heat insulating material is foamed, the wiring can be accommodated in the recess. Accordingly, it is possible to easily carry out the foaming work of the heat insulating material while preventing the wiring from being caught. Moreover, since the back upper part of the inner surface of the main body casing is normally formed in a curved surface, the thickness of the heat insulating material can be sufficiently ensured even if the recess is provided.

  In addition, according to the present invention, since the wiring storage box having the insertion portion for inserting the wiring on the upper surface and the lower surface is attached to the recess, the upper end of the back surface of the main body housing is covered with the wiring storage box, and the wiring is not exposed to improve the beauty can do. Further, when the heat insulating material is foamed by surrounding the main body casing with a mold, the wiring can be stored in the wiring storage box, and the foaming work of the heat insulating material can be performed more easily.

  Further, according to the present invention, the wiring storage box has a storage part that can store and store a plurality of wirings by means of a partition plate. It can be easily removed and connected to electrical components in the electrical storage.

  In addition, according to the present invention, since the handle portion to be gripped during the transportation of the main body casing is integrally formed on the upper surface of the wiring storage box, the number of parts can be reduced.

  In addition, according to the present invention, since the upper lid that covers the upper surface of the electrical component storage portion and the insertion portion is provided, the aesthetics can be improved by covering the electrical component and the wiring.
