<p><P>PROBLEM TO BE SOLVED: To surely judge the abrasion of a coupling section such as a clamp part, a coupling member, etc. even if vibration occurs in a transmission line. <P>SOLUTION: A spacer for a transmission line is equipped with the clamp part 1 which is equipped with a retaining part 12 for retaining a conductor and a clevis part 41, and the coupling member 2 coupled with the clamp part 1, and the end of the coupling member 2 is coupled with it via a supporting shaft 7 at the clevis part 41. Then, this spacer for a transmission line is equipped with a detection means 9 which detects the amount of abrasion of the opposition part between the clevis part 41 and the coupling member 2. The detection means 9 is constituted of a projection 91 which is made by projecting the end of the clevis part 41 in a direction orthogonal to the axis of the supporting shaft 7, by the amount of thickness of the quantity of tolerable abrasion from the face, opposed to the coupling member 2, of the clevis part 41. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
