- the core cable 23 is passed through the ring member 36, the strand 27 is passed through the ring member 37, and the passed portions of the core cable 23 and the strand 27 are each tied with a wire or the like so as to assume an annular shape.
- the first main rope 21 is rotated with respect to the second leader strip 4. It is therefore possible to prevent the first main rope 21 from being wrenched with respect to the first leader strip 4 even when the first main rope 21 is looped around a plurality of sheaves continuously. As a result, it is possible to prevent the connection portion between the first leader strip 4 and the first main rope 21 from being wrenched to a rupture.
