To provide a suspension wire protective cover that improves safety by preventing its attaching failure to a suspension wire.SOLUTION: A flange portion 4 of one division body 2 composing a suspension wire protective cover in a spool form has an insertion hole 9a having an exit on a fitting projection 5 side of the other division body 2. The fitting projection 5 of the other division body 2 has a notch 10a that blocks axial relative movement due to entry of a stopper 11. The stopper 11 can be elastically reduced in size and deformed, penetrates through the narrow insertion hole 9a, returns to its original form after its leading end passed through the insertion hole, so that a lock projection 13b is prevented from passing and separating from the insertion hole 9a. The stopper 11 passed through the insertion hole 9a and located in a passage and separation preventing position engages with an engagement portion 10 of the engagement projection 5 to block axial relative movement of the flange portion 4 and the fitting projection 5 so as to lock fitting of the division bodies 2, 2. The stopper 11 cannot be disposed in an engaged position due to imperfect fitted states of the flange portion 4 and the fitting projection 5, so that fitting failure of the division bodies 2, 2 is made clear.SELECTED DRAWING: Figure 8
【課題】 吊架線への装着不良を防止して安全性を向上する吊架線保護カバーを提供する。【解決手段】 糸巻状の吊架線保護カバーを構成する一方の分割体2の鍔部4に他方の分割体2の嵌合凸部5側を出口とする通し孔9aを備える。他方の分割体2の嵌合凸部5に、ストッパ11が進入して軸線方向の相対移動を阻止する切り欠き部10aを備える。ストッパ11は弾性的に縮小変形可能で、狭小幅の通し孔9aを貫通し、先端部が抜け出たら原形に復帰してロック用突起13bが通し孔9aから抜け止めされる。通し孔9aに通した抜け止め位置のストッパ11は、嵌合凸部5の係合部10に係合して鍔部4と嵌合凸部5の軸線方向の相対移動を阻止して分割体2,2の組み付けをロックする。鍔部4と嵌合凸部5との不完全嵌合状態でストッパ11が係合位置に配置できず、分割体2,2の組み付け不良を明確にする。【選択図】 図8
