PURPOSE: To improve the coating workability and the sticking workability of a dew condensation preventing material by forming a main body case in an assembling type in which front plates, a back plate, a bottom plate, a top plate and side plates on both sides are assembled into a box shape.
CONSTITUTION: Inserting members 15 and 16 formed on the gable side of a bottom plate 8 are inserted to be joined respectively into front plates 5 and 6 and grooves 13 and 14 formed in a U-shape at the lower end portion of a back plate 7, and then a top plate 11 is covered thereon. Then, a put 29 and a bolt through hole 30 are aligned in position, and joined by means of a bolt 31 to thereby form a square cylinder having an opening part between the front plates 5 and 6 and having openings on both side portions. Then, side plates 9 and 10 are fitted into the openings on both sides of the square cylinder, and are positioned with threaded holes 34 and 33 and fixed by means of a screw 35. As a result, respective plates can be coated in a single body and a dew condensation material can be stuck, and the painting workability and the dew condensation preventing material sticking workability can be improved.
