Therefore, it is not necessary to separately prepare a temporary holding member for temporarily holding the cover main body lead wire 39 at the time of jig setting, so that workability is improved and the cost can be reduced by reducing the number of parts. It is possible to prevent the main body lead wire 39 from being damaged or cut by being pressed against the jig, and the quality can be stabilized.

  Furthermore, in this embodiment, since the rear wall body 18 is also provided with a wall body housing portion 25 for housing lead wires and the like, the dew condensation prevention heater for the dew condensation prevention heater 23 incorporated in the rear wall body 18 is used. The storage part such as the lead body 26 and the wall body lead wire 27 from the refrigerator body 1 and the wall body connector 28 to be connected to these is also the inner wall of the inner box 3 of the refrigerator body as in the case of the water supply pipe 33. Therefore, it is possible to perform rational storage processing using the wall body storage portion 25 provided on the back wall body 18.

  In addition, since the wall body storage portion 25 is provided so as to be located on the side of the cool air passage 17 located on the back surface of the back wall body 18, the wall thickness of the portion is reduced by providing the wall body storage portion 25. However, since the cold air passage 17 does not exist on the rear surface, there is no problem of cold radiation, and the wall body storage portion 25 is provided to reduce the wall thickness only in the rear wall body 18 and the wall of the refrigerator main body 1. Since the thickness is not related at all, it does not adversely affect the thermal insulation and internal volume.

  Also, a wall body temporary storage portion 29 is provided in the partition plate 6 located above the wall body storage portion 25 of the back wall body 18 so that the wall body main body lead for the dew condensation prevention heater 23 pulled out from the refrigerator main body side is provided. Since the wire 27 and the wall connector 28 can be temporarily stored, as in the case of the water supply pipe 33 side, the partition plate 5 is set in the refrigerator body inner box 3 and pressed against the refrigerator body inner box side with a jig. When the foam heat insulating material 4 is filled and foamed, the wall main body lead wire 27 can be stored in the wall temporary storage portion 29 of the partition plate 5. Accordingly, it is not necessary to separately prepare a temporary holding member for temporarily holding the wall main body lead wire 27 when the jig is set, so that the workability is improved and the cost can be reduced by reducing the number of parts. It is possible to prevent the wall main body lead wire 27 from being damaged or cut by being pressed against the jig, and the quality can be stabilized.

  Although the embodiment of the present invention has been described above, the configuration described in the above embodiment is shown as an example for carrying out the present invention, and various modifications can be made within the scope of achieving the object of the present invention. Needless to say.

  The present invention can provide a refrigerator that can store lead wires and the like and can easily perform maintenance work without providing a storage portion such as lead wires on the refrigerator main body side. Therefore, it can be widely applied to many uses such as commercial refrigerators and showcases as well as home use.
