〔The invention's effect〕

As described in detail above, according to the present invention, a columnar member having a flat surface and a surface in which a concave groove is formed is provided inside the flat end surface of the panel and between the facing flange portions of the inner and outer surface members. Since the heat insulating panel is configured such that the flat surface or the concave groove is arranged so as to be exposed, if the flat surface and the concave groove are exposed between the flange portions, the flat panel and the concave groove can be formed as a convex portion of another panel. Not only a combination of the above, but also a transparent door can be arranged, and it is possible to correspond to any part as a heat insulating panel forming a corner portion of the box body. Further, if the columnar member is formed of foamed resin, the difference in thermal conductivity from the foamed heat insulating material can be made small, so that it is possible to prevent dew condensation from concentrating in the vicinity of the corners of the heat insulating box, and especially for transparent doors. It is possible to reduce the dew condensation on the front surface of the box body in which Furthermore, it is possible to combine the concave groove and the convex portion, and by inserting the pin corresponding to the hook of the rotary type lock from the positioning groove of the columnar member, the troublesome pin positioning work can be simplified. Can be easily connected and fixed to panels.
