  Further, in the present embodiment, the unit partition wall 31 is deformed so as to slightly warp due to the temperature change of the refrigerating chamber 17 and the heating chamber 18, and the opposing surface 31 A of the unit partition wall 31 and the door packing 61 There is a concern that the adherence of the In this respect, in the present embodiment, the spacer member 60 is inserted into the gap S1 between the pair of doors 19 and 19. Thereby, even if a gap is generated between the door packing 61 and the facing surface 31A, the gap S1 is closed by the spacer member 60, so the outside air is stored in the refrigerator compartment 17 and the heating compartment 18 It is possible to suppress the situation in which the air in the cold storage room 17 and the heating room 18 leaks to the outside. Further, by inserting the spacer member 60 into the gap S1, the situation in which the pair of doors 19, 19 is opened can be more reliably suppressed. Therefore, it is possible to suppress the situation in which the door 19 is opened when the adhesion between the door packing 61 and the facing surface 31A is temporarily reduced. In addition, when running the hot and cold delivery trolley 10, etc., although the door 19 tries to turn in the opening direction due to the inertia of the door 19, the door 19 is inserted by inserting the spacer member 60 into the gap S1. Can be more reliably suppressed.

  In addition, when opening a pair of doors 19 and 19, it is necessary to remove the spacer member 60 from clearance gap S1. In the present embodiment, the outer wall portion of the heat insulation box 11 and the outer wall portion of the machine chamber 13 are made of metal, for example, and the spacer member 60 has the magnet 62. Therefore, when the door 19 is opened, the spacer member 60 can be easily fixed to the outer wall portion of the heat insulating box 11 or the outer wall portion of the machine chamber 13 by the magnet 62.

  Further, in the configuration of the present embodiment, instead of arranging the unit partition wall 31 below the cold storage room 17 and the heating room 18 on the storage room 16B side, the storage space configuration member 50 is arranged. The cold air or the hot air is supplied to the storage space S2 by using the intermediate wall 15 for supplying the air and the panel 40 for supplying the hot air to the heating room 18. For this reason, it is not necessary to provide a dedicated duct for supplying cold air or warm air to the storage space S2, and a simpler configuration can be achieved.
