PURPOSE: A twisting device of a catch cord yarn in which two shaft holes placed at the inlet part of a twisting device is removed and a passage is formed in a twisted structure having a tunnel shape is provided, which generates almost no tangling of holding residual yarns during twisting and increases twisting strength. CONSTITUTION: This twisting device for catch cord yarn is characterized in that twisted piece of iron(4) adhered closely to the inner wall of a twisting device(1) of a catch cord yarn in a pipe shape has a circular ring(3) for supporting, and its opposite side is welded to the inlet part(5) of the twisting device of the catch cord yarn with argon. The device promotes productivity and saves manpower and time for maintaining and repairing.
