要素１の剛性が小さいときは、この影響が大きく、Ｘ値
が大きくなるため、撚りが入らなくなってしまう。However, the conventional SZ twisting apparatus has a problem that the efficiency of twisting itself is not always high due to the twisting structure. That is, since friction always exists between the central element 1 and the outer peripheral element 2 that is SZ-reversed, even if the outer peripheral element 2 is rotated by ± N in the SZ direction, the central element 1 is also rotated by the friction. At the same time, X rotation is performed in the same direction to some extent (± X rotation), and as a result, twisting is limited to (N−X) rotation. As a result, the twist pitch becomes relatively long, which may cause a problem in characteristics as a cable. In particular, when the rigidity of the center element 1 is small, the influence is large and the X value is large, so that twisting cannot be performed.
