Double rope structure

Provided is a double rope structure comprising an inner layer and an outer layer. In the double rope structure (10), the inner layer (3) is formed from high-strength/high-modulus fibers having a yarn strength of 20 cN/dtex or more and a yarn modulus of 400 cN/dtex or more, and the rope structure (10) is cut at a predetermined length to obtain cut parts (V). The ratio of the average value of the yarn lengths of the inner layer constituting the cut-off part (V) to the rope length of the cut-off part (V) is 1.005-1.200 in terms of yarn length/rope length. 本发明提供由内层和外层构成的双重绳索结构体。在上述双重绳索结构体(10)中，内层(3)由纱强度为20cN/dtex以上且纱弹性模量为400cN/dtex以上的高强度/高弹性模量纤维形成，将该绳索结构体(10)以给定的长度切断而得到切断部(V)，构成上述切断部(V)的内层的纱长度的平均值相对于切断部(V)的绳索长度之比以纱长度/绳索长度计为1.005以上且1.200以下。
