PURPOSE: To eliminate the needs for adjustment after attaching panels by a method in which a loose fit hole having partly a holder is provided for one end side of a support arm, an expandible support plate is provided on the other end, and a projection for fitting is also provided on both surface and back sides of the tip of the support plate.
CONSTITUTION: A nut 6 with a loose fit hole 22 formed partly in a holder 23 is provided on one end of a support arm 21, and an expansible support base 24 having a projected support plate is attached to the other end. Projections 32a and 32b for fitting are provided to the tip of the support plate to make up a connecting part 20. A fitting bar 3 is fitted into the fit hole 22, and the nut 6 is turned by the support arm 21. Since the preceding panel attached is connected with the next panel by the connecting part 20, adjustment after attaching the panels can be made unnecessary, and the number of fitting bars 3, parts 7 to be attached, and female screws 13 can also be reduced.
