[Problems to be solved by the device]

 However, in the above-mentioned conventional structure, since the string has to be inserted into the through hole, there is a problem that it is troublesome and the operability is poor.

Therefore, it is conceivable to form a kerf from the through hole inside the plate body to the outside. However, depending on the directionality of this kerf, there is a problem that the string is likely to come off the through-hole through the kerf during or after the fastening operation.

In the case of forming the engaging groove, the string to be fastened is unstable because the string to be fastened moves along the outer periphery of the binding tool, so that the workability to fasten is poor and the string to be fastened may come off. There is a problem.

In view of the above-mentioned problems, the present invention provides an engaging concave portion for fixing a string at a certain position so that the stringing operation is not troublesome and the string is securely bound. The purpose is to provide a tool.
