Since it is a very simple structure that is performed by a simple operation that only pushes and deforms in the reverse direction, automation of the storage operation of the yarn 1 can be easily realized, and consequently the workability in the storage operation of the yarn 1 is dramatically improved. Improvement can be expected.

The support part 14b supports the connecting part 5 between the first thread holding body 7 and the plate-like base 2. The thread holding part 4 is opened (the rising part 7b faces the outside of the thread winding part 3). A thread passage allowing portion 8 that allows passage of the suture thread 1 is formed (withdrawing from the position). In this state, the suture thread 1 is passed through the thread passage allowing portion 8 to wind the suture thread 1 around the thread winding portion 3. (See Figs. 13 and 14). After the winding around the bobbin winding portion 3 is completed, the rising portion 7b is opposed to the outside of the bobbin winding portion 3 by releasing the pressing of the second yarn holding body 7 and the plate-like base 2 to the connecting portion 5. When arranged in the position, the thread passage allowing portion 8 disappears, and the suture thread 1 wound around the thread winding portion 3 is prevented from falling off (see FIG. 15). Note that the proximal end portion of the suture thread 1 is held by the tension of the suture thread 1 without being locked to the plate-like substrate 2.

  Since the present embodiment is configured as described above, the yarn holding portion 4 can be formed in the yarn holding portion 4 and the yarn passing by simply pressing and deforming a predetermined portion of the plate-like substrate 2 or releasing the pressing deformation. Since the disappearance of the permissible portion 8 is performed extremely easily, the storage state of the suture (the state in which the suture 1 is wound around the spool 3 without dropping off) is extremely simple as compared to the conventional example described above. Will be obtained.

  Further, in this embodiment, the structure for easily obtaining the above-described storage state of the suture thread 1 (the structure for forming the thread passage allowing portion 8 in the thread holding portion 4) is simply a predetermined portion of the plate-like substrate 2. Since it has a very simple structure that is performed by a simple operation that only presses and deforms the front and back surfaces, the storage operation of the suture thread 1 can be easily automated, and the workability in the storage operation of the suture thread 1 can be easily achieved. It will be possible to hope for a dramatic improvement.
