3. Each of the ribs 20 for securing the rigidity in the lateral direction
4,... Are arranged so as to intersect in the vertical direction, and are reinforced in such a manner as to be supported by the pillar 205, which secures the rigidity in the vertical direction, and the rigidity of the wall 202 of the luggage compartment 201 is ensured. (See Japanese Utility Model Laid-Open No. 2-3481).

On the other hand, in the luggage compartment of a refrigerator car or a freezer car,
In order to ensure the heat insulation of the luggage compartment, a cool insulating wall portion 211 having a structure as shown in FIG. 9 is used (see Japanese Utility Model Application Laid-Open No. Sho 56-118885).

[0005] That is, the cold insulating wall portion 211 is composed of an outer plate 212 made of an extruded aluminum material, a heat insulating material 213 provided on the outer plate 212, and a clothing material 214 covering the surface of the heat insulating material 213. The outer plate 2

Also, at this time, since a housing space capable of housing a heat insulating material is formed between the general portion of each of the outer plates and the inner plate, it is necessary to ensure the heat insulating property of the insulated car, the frozen car, and the like. When forming the wall portion of the luggage compartment, by arranging a heat insulating material in the accommodation space when fixing the non-metallic inner plate, by the heat insulating material and the non-metallic inner plate, Heat insulation in the accommodation room is ensured.

Further, the inner plates are separated from each other, and a space is formed between adjacent inner plates.

[0012] Thereby, the rigid closed cross section and the inner plate of the wall are arranged in an orthogonal 直交 shape.
The rigidity can be ensured while reducing the weight of the wall.

Further, a first heat insulating material is provided in the accommodation space, and a second heat insulating material is provided on the inner surface of each of the plate members.
