If the wire is subjected to a tensile force in the state where the wire is twisted or bent, even if the wire is not broken at a tension smaller than the limit tension, the stress is concentrated on the twisted portion and the bend occurs.

Therefore, when using a device using a wire, care must be taken to twist, bend, and friction of the wire. Further, the second wire is a wire that is driven along the first and second swaging parts 130 and 150 as the slope of the lifting body A is changed during lifting, and it is necessary to prevent the twisting and twisting at the time of coupling do.
