<p>PROBLEM TO BE SOLVED: To enable constitution with fewer part items number to thereby attain an inexpensive production by constructing a plate frame of a pair of substantially U-shaped side members capable of being connected to mutually opposed free ends and a substantially I-shaped intermediate member connected to between these side members. SOLUTION: A plate frame is constructed of a pair of substantially U-shaped side members 22, 22, a substantially I shaped intermediate member 23 connected to between the members 22, 22, and connection members 24 installed between the members 22, 22, and between the sides 22, 22 and intermediate member 23. Each member 22 is formed with a connection boss 222 at a tip of its one of free ends 221 and a boss hole 224 into which the boss 222 can be inserted at a tip of the other free end 223, and also with a stepped part 226, into which a decoration plate 3 is fitted to be flush therewith at the inner side of its base end 225. Accordingly, the paired side members 22, 22 are mutually connected via the intermediate member 23 interposed therebetween to form the plate frame.</p> |
