PURPOSE:To make lubrication favorable, reduce resistance to sliding, and improve durability in such a way that steel wire is wound in a spiral shape keeping intervals in the axial direction, around the core made of one piece of round steel wire, and the outer peripheral face of the outer winding is smoothly made. CONSTITUTION:An inner cable 1 is integrated in such a way that an outer winding 11 made of one piece of round steel wire which has a circular section in smaller diameter than the core 10 does is wound in a spiral shape keeping intervals in th axial direction around a core 10 made of one piece of round steel wire, and its outer peripheral face 11a is smoothed by swaging. |
