摘要： PROBLEM TO BE SOLVED: To prevent a feeder cable from being a hindrance to a turning operation of a link, and to prevent the feeder cable from being broken by the action of an unreasonable tensile force or external force on the feeder cable. SOLUTION: Since the feeder cable 21 for supplying electric power to a lifting magnet 20 is guided at both the ends of a connecting link 23b by a guide so as to be arranged in the longitudinal direction of the connecting link 23b, the feeder cable 21 is prevented from coming off from the connecting link 23b, even if a connecting link 23b is rotated by a cylinder 24. Since the feeder cable 21 is covered with a protective cover which is arranged in the longitudinal direction of the connecting link 23b, the feeder cable 21 can be prevented from being damaged by an external force, and there is no risk that the feeder cable 21 may be pulled and broken. Additionally, since the feeder cable 21 is arranged in the state of being separated in an outside part of a supporting link 23a and having a sufficient length, there is no risk that the unreasonable external force may be applied to the feeder cable 21 when the link 23 rotatively operates.
