As described above, the volume of the refrigerated space in the luggage compartment 20 to be cooled by the cooling device 50 can be changed in two stages only by opening and closing the partition plate 30 in the luggage compartment 20.
The output of the cooling device 50 can be adjusted so as to be suppressed according to the amount of the refrigerated baggage required. Also, refrigerated baggage and luggage not suitable for refrigeration can be carried together. Of course, without operating the cooling device 50, the entire luggage compartment 20 may be kept at normal temperature to transport non-refrigerated luggage.

The refrigerated vehicle according to the present invention is not limited to the embodiment described above. In the above-described embodiment, an example in which the invention is applied to a van-type vehicle is described. However, the invention may be applied to, for example, a box-type carrier of a large truck, a container of a railway vehicle, and the like. In addition, apart from the hydraulic damper 36,
It is preferable to provide a lock mechanism for maintaining the partition 30 in an opened and substantially horizontal state. Of course, the partition plate 3
0 and the specific shape of the opening frame 23 are not limited to those illustrated.

[0046]

According to the refrigerating vehicle of the present invention, the partitioning plate for separating the one end space where the cooling device is located and the other end space where the cooling device is not located is provided in the luggage compartment so that it can be opened and closed.
One luggage compartment can be easily divided into a refrigerated compartment and a room temperature compartment, and the volume of the luggage compartment is increased or decreased according to the amount of refrigerated luggage required.
The output of the cooling device can be adjusted to be suppressed so that the cost can be reduced, and the refrigerated baggage and the unsuitable refrigerated baggage can be carried together.
