[Problems to be Solved by the Invention] The above-mentioned vertical refrigerator 1
In No. 0, the tray 26 accommodating a heavy article to be stored may be placed, so the tray plates 32, 32 are made of a strong stainless steel plate. The tray 26 itself is made of aluminum or stainless steel, which has good thermal conductivity. In this case, the horizontal side 32b of the tray plate 32 and the tray 26
As shown in FIG. 8, the bottom surface of the tray is in surface contact with the bottom surface of the tray. Therefore, when a heavy article to be stored is accommodated in the tray 26, the contact resistance becomes large, and smooth entry / exit cannot be performed. Further, since the metals are in surface contact with each other, it is pointed out that there is a drawback that when the tray 26 is put in or taken out, it makes an unpleasant sound and makes the user uncomfortable. Although a similar tray support structure is adopted in a freezer for freezing and storing stored articles,
Since the tray and the tray plate are in surface contact with each other in the freezer, there is a problem that the contact surface is frozen and the tray cannot be pulled out.

In the case of the above-mentioned refrigerator 36, the inner wall 2
Horizontal side 32b of the tray plate 32 directly attached to 8
Since the tray 26 is placed in surface contact with the tray 26, the heat of the heater 40 is transferred via the tray plate 32 to the portion in contact with the horizontal side 32b of the tray 26,
May be partly hot. That is, tray 2
There is a temperature difference inside 6, which causes various problems. For example, when the bread dough is aged, the bread dough stored in a portion where the tray plate 32 and the tray 26 are in contact with each other has a higher fermentation speed than the bread dough stored in another portion because the tray 26 becomes hot. Get faster,
This leads to overageing problems. Even in the warm storage 36, due to the surface contact between the tray 26 and the tray plate 32,
There are inherent problems that the smooth movement of the tray 26 is obstructed and a problem that an unpleasant sound is generated.

[0007]
