交換等のメンテナンスも容易に行える。As described above, the electric heater 8 can keep the temperature in the storage room 7 relatively long by supplying power from the storage battery 11. Also, the wheels 4 in which the storage battery 11 becomes a dead space,
Since it is arranged between the four, the loading efficiency on the carrier Y is improved. In particular, since it is between the wheels 4 and 4 of the bottom surface 5A, it does not hinder the claws F of the forklift and does not hinder the cargo handling work. Furthermore, the relatively heavy storage battery 11 is
Is located at the bottom, the center of gravity of the cold storage 1 can be reduced, and it is difficult for the refrigerator 1 to fall down when moving using the wheels 4. Furthermore,
Since the storage battery 11 is outside the storage room 7, even if the internal solution leaks, the food in the storage room 7 is not damaged, and maintenance such as replacement in this case can be easily performed.
