<p>PROBLEM TO BE SOLVED: To secure surely and cheaply the mutual conductivity between receiving tools, by coupling the receiving tools through a coupling tool while bringing them into direct continuities. SOLUTION: A coupling structure comprising receiving tools 1 and a coupling tool 4 for coupling the receiving tools 1 to each other thereby, wherein through holes 2a. 4a for passing respectively attachment bolts 5 therethrough are formed respectively in the opposed positions of the receiving tools 1 and the coupling tool 4, and further, in the peripheral edge portion of each through hole 4a of the coupling tool 4, a protrusion 4b for removing a surface processing film by inserting it in an engagement way forcedly into each through hole 2a of a master beam member 2 and for connecting in a conductive state the coupling tool 4 with the receiving tool 1 is provided.</p> |
