Further, the pair of the holding metal fittings 510, 510 are fastened at their intermediate portions in the height direction using bolts 520 and nuts 530.

[0023]

According to the present invention, since the influence of the temperature drop of the roof plate is difficult to reach each plate-like portion and the tightening bolts and nuts due to the heat transfer blocking function which is the characteristic of the synthetic resin, it becomes difficult to cool them. Condensation is less likely to occur on the surface. Therefore, even if a heat insulating material is loaded on the lower side of the roof plate or a ceiling material is placed on the base material, the heat insulating performance of the heat insulating material is deteriorated early due to the dew condensation water, or It is possible to prevent the material from decaying at an early stage, and at the same time, to effectively suppress the roof receiving frame itself from rusting due to moisture due to dew condensation.

Further, the tightening bolts and nuts have the function of tightening the first and second intermediate plate portions to fix the legs of the suspension, and the tightening of the first and second plate-like portions between them. Since it also has the function of fixing the mounting plate, it is not necessary to separately provide bolts and nuts to exert each function, reducing the number of parts and eventually reducing costs. effective.
