First, as described above, one end of the string 2 is attached to the attachment part 27 of the connecting part 3, and the other end of the string 2 is attached to the attachment part 13 of the length adjusting part 4. Next, the middle part of the string 2 is held by the holding part 15 of the length adjusting part 4 as described above. Next, the fitting portion 38 of the string passing portion 39 which is removed from the fitting portion 36 by removing the fitting portion 38 is held by the holding portion 15 from the other end portion attached to the attachment portion 13 of the string 2. Then, it passes through the inside of the loop-shaped portion 41 up to the midway portion, and thereafter, the tip end portion of the fitting portion 38 is fitted into the fitted portion 36 to make the string passing portion 39 endless. Thereby, both sides of the string 2 are connected to form a string ring. Note that this procedure is an example, and the attaching portion 27 and the attaching portion 13 are attached to the end of the cord 2, the holding portion 15 holds the middle portion of the cord 2, and the cord 2 is passed through the string passing portion 39. Work may be done before and after.

  The strap made in this way has a hanging object such as a name tag attached to an intermediate portion between the portion held by the holding portion 15 of the string 2 and one end portion attached to the attachment portion 27, for example. Used as a neck strap. Further, by adjusting the length of the loop-shaped part 41 by sliding the string 2 with respect to the holding part 15, the size of the string ring can be adjusted to the size around the neck of the user. Further, the portion from the other end portion attached to the attachment portion 13 of the cord 2 to the intermediate portion passed through the string passage portion 39 and the intermediate portion held by the holding portion 15 from the intermediate portion passed through the string passage portion 39. The part to the part can be piled up, and in this case, the narrowed part cannot be formed in a part of the string, and the appearance is good.

  In addition, safety during use is high. In other words, when a tension that greatly exceeds the holding force of the cord 2 by the holding portion 15 is applied to the cord 2 due to, for example, a strap around the neck being caught by an object, the cord 2 slides with respect to the holding portion 15. As a result, the length of the loop-shaped portion 41 is shortened. Finally, the connecting part 3 and the length adjusting part 4 come into contact with each other, and the string 2 cannot be slid with respect to the holding part 15 any more. A larger tension acts on the cord 2. Then, the fitting part 38 of the connecting part 3 is pulled to the length adjusting part 4 side by the string 2 wound around the connecting part 3, and the tip part of the fitting part 38 is fitted to the fitted part as shown in FIG. The two ends of the annular string passage part 39 are separated from 36 and the string ring is unwound. For this reason, it is possible to prevent the neck from being pulled with an excessive force by a string that is caught on an object.

  Moreover, the string passing part 39 which has the function which connects the both sides of the string 2, and the function which releases a string when excessive tension | tensile_strength acts on a string, the both ends of the circumferential direction connected by fitting isolate | separate Since the string can be unwound by, it can be formed integrally. Therefore, the connecting part 3 can be formed as a single member by integrally forming the attachment portion 27 and the string passage portion 39. Furthermore, the length adjusting part 4 can also be formed as a single member by integrally forming the attachment portion 13 and the holding portion 15. Therefore, the number of members of the string connector 1 can be reduced and the manufacturing cost can be suppressed.

  In addition, you may apply this invention also to the string connector used for uses other than the thing which makes a linear string ring shape, or a neck strap.
