The present invention is a low temperature refrigerator constructed as described above, wherein an outside rail is provided outside the opening, and an inside rail is provided inside the storage room on an extension of the outside rail. Since a heater is provided on the rail and a door receiver is provided below the heat insulating door located between the inside rail and the outside rail, cold air leakage or outside air intrusion from below the heat insulating door is avoided. Furthermore, even if the inside rails are heated by the heater and the outside air slightly invades, dew condensation or freezing can be avoided. As a result, the cart can be moved smoothly when carrying in and out of stored items. Therefore, the loading and unloading work can be smoothly performed.

Since the rail extending from the outside to the inside of the storage chamber 3 is embedded in the floor, the heater is embedded in the floor of the storage chamber side near the rail, and the heater is embedded in the floor below the heat insulating door. When the heat insulation door is closed, it is possible to avoid cold air leaking from below the heat insulation door or invasion of outside air. Furthermore, the heater condenses or freezes the bottom of the heat insulation door and the rail inside the heat insulation door. As a result, the dolly can be smoothed when loading and unloading stored items.
It is possible to smoothly carry out the carrying-in and carrying-out work.
