PROBLEM TO BE SOLVED: To provide a tightening device of an insulation trolley line which achieves higher workability with a relatively simple structure, and to provide an insulation trolley using the tightening device.SOLUTION: A tightening device 10 of an insulation trolley line 20a includes: a base part 1; an insulator part 2; and a pair of spring materials 3. The base part 1 includes a first holding part 1a and holds a first end part 21a of a first insulation trolley line 21 with the first holding part 1a. The insulator part 2 includes a second holding part 2a and holds a second end part 22a of a second insulation trolley line 22 with the second holding part 2a. The spring materials 3 apply elastic force to an area between the base part 1 and the insulator part 2 in a direction such that the first holding part 1a and the second holding part 2a move close to each other. The base part 1 houses the insulator part 2 so that the insulator part 2 may move along a direction that the elastic force is applied by the spring materials 3. The pair of spring materials 3 is disposed in a manner such that the spring materials 3 face each other across a virtual reference line 24 extending in an arrangement direction of the first holding part 1a and the second holding part 2a.SELECTED DRAWING: Figure 1
【課題】比較的簡単な構造で、より高い施工性を備えた絶縁トロリー線の引締め装置およびそれを用いた絶縁トロリーを提供する。【解決手段】絶縁トロリー線20aの引締め装置10は、ベース部1と、碍子部2と、一対のばね材3と、を備えている。ベース部1は、第1保持部1aを備え、第1絶縁トロリー線21の第1端部21aを第1保持部1aにより保持する。碍子部2は、第2保持部2aを備え、第2絶縁トロリー線22の第2端部22aを第2保持部2aにより保持する。ばね材3は、第1保持部1aと第2保持部2aとを近づける向きにベース部1と碍子部2との間に弾性力を付与する。ベース部1は、ばね材3により弾性力が付与される方向に沿って、碍子部2を移動可能に収容している。一対のばね材3は、第1保持部1aと第2保持部2aとの配置方向に延びた仮想の基準線24を介して、対向して配置されている。【選択図】図1
