<p>PROBLEM TO BE SOLVED: To solve the problem in a conventional method, that confirmation by a scale as to whether the internal is as set on the support of the scale are required, and if it is yes, determines the internal by tightening fastening elements, when the interval is adjusted with the conventional scale and an extension bracket with a slit, which becomes troublesome and time-consuming especially in narrow and dark places such as in tunnels, buildings, ships, where no good foothold can be secured. SOLUTION: This spacer for an extension bracket for a rack and the like is made of the extension bracket 4 for the rack and the like that absorbs the elongation or shrinkage of the rack and the like caused by temperature change and a spacer 5, provided in such a way as to be freely mountable and detachable between holes 400 and a slit 401 for the fastening elements of the extension bracket. An interval 3 between the end surfaces 1a, 1'a of one and the other racks and the like 1, 1' can be adjusted surely and readily using the extension bracket. The adjustment of the interval can be made simply and precisely witless man hours of workers.</p> |
