PROBLEM TO BE SOLVED: To provide a mechanism for preventing cutting of a running wire caused by circumferential rotation of the running wire. SOLUTION: This mechanism comprises connecting a functional element 2 with a running wire 4. A guide element 3 has a pipe connector 31 connecting with a leading pipe 5 and a wire connecting part 32 in which a running wire 4 is inserted and so the connecting part is engaged with the leading pipe 5 and connected with the running wire 4. The function element 2 pushes a guide element 3 according to running of the running wire 4 and, thereby, the leading pipe 5 is moved. By interlocking the running wire 4 with the leading pipe 5, even if the running wire 4 circumferentially rotates, the function element 2 of the connecting part also rotates around the running wire 4 as the rotation axis. Thereby, torsion load is not applied on the running wire 4 itself and so cutting of the running wire 4 is prevented. |
