<p><P>PROBLEM TO BE SOLVED: To provide a coupling structure for a passing rod, which allows an easy passing of a cable even if a suspension wire and a spiral hanger are curved. <P>SOLUTION: The coupling structure is for a passing rod 5 which passes a cable 6 through a cylindrical space formed by a spiral hanger 3 arranged along a suspension wire 2 laid between electric poles 1 and 1. A guiding tool 4 arranging a plurality of elastically deformable bowed bodies 4b around the core material 4a and guiding a passing rod 5 so that it may be driven in the cylindrical space, and the passing rod 5 joined at the rear end part of the guiding tool 4 are coupled by a movable coupling tool 10 which can be bent in any direction, up and down, right to left, or in the diagonal directions. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
