- 左回りの螺旋部と右回りの螺旋部が反転部を介して、軸線にそって交互に連なり構成されたケーブルの螺旋状支持具であって、
軸線方向に隣り合う前記反転部は、軸線から見た側面において互いに対向配置されると共に、前記左回り螺旋部及び右回り螺旋部によって作られる円の中心を通る水平線より上側で、前記円の接線方向に突出し、かつ、軸線方向に見て、互いの先端部と前記円との間隔は支持線等の外径より大きく形成されており、
前記左回り螺旋部と右回り螺旋部の螺旋巻き角度は、前記支持線等を内部へ取り込みながら押し出していくときに、水平方向の力が上向きの力より大きい前進する推力として作用するように45°未満となっていることを特徴とするケーブルの螺旋状支持具。
