As shown in FIGS. 1 and 2, the width of the tape around which the wire is wound is wider than the winding frame, and serrated reliefs are attached to both sides. The serrated projections on the undulating portion are used to lock the winding wire when pulling out the winding wire 44, as shown in Fig. 2, and the winding wire is hooked to the serrated projections and pulled out of the winding frame. It can be pulled out easily.
