摘要： PROBLEM TO BE SOLVED: To securely prevent fall of a carriage and suppress fall quantity when a wire is cut.
SOLUTION: In the carriage 32, holders 88 are mounted in sides of a pair of guide rails 14. Engagement members 92 are journaled to the holders 88. One end parts of the engagement members 92 having claws 96 are opposed to back faces 14B of the guide rails 14, and link levers 86 are journaled to the other end sides. The link levers 86 are connected to a support member 70. When the link levers 86 are pulled down by energizing force of coil springs 80 caused by cutting of the wire 50, the link levers 86 rotate the engagement members 92 so as to make the claws 96 abut on the guide rails 14. Thus, while the fall of the carriage 32 is securely prevented, the lowering amount of the carriage 32 can be suppressed at the time of prevention of the fall.
