PROBLEM TO BE SOLVED: To provide a wire fixing mechanism configured such that a wire inserted through a wire insertion pipe is circulated in one direction but is fixed in the opposite direction so that the wire cannot be circulated in the reverse direction. SOLUTION: An outer cylindrical body having an inner wall having a tapered shape, an inner cylindrical body slidable inside the outer cylindrical body, a wire inserted through a central portion of the inner cylindrical body, and a peripheral wall of the inner cylindrical body are perforated. A plurality of ball loose fitting holes can be freely fitted into the ball loose fitting holes, and when the ball loose fitting holes of the inner cylindrical body and the tapered portion of the outer cylindrical body have a corresponding positional relationship, the central portion of the inner cylindrical body is A wire fixing mechanism for fixing the one-way flow of the wire in the wire insertion pipe, which is composed of a stopper-ball that press-contacts the surface of the wire to be inserted, is configured.
