超加すると必要以上のコスI・高となる。That is, the distance W between the inner sides of both ear parts 14.14 is 11 to 16 m.
m, if it is less than 11 mm, it will not be possible to smoothly contact the fingertips or nails with the rear edge 9, and this will cause the bow tension piece 6 to be grasped at a position offset to the left or right from the axis line, and the lever for opening will not be able to be used. There are problems such as increasing the pulling force of the operation and bending the front end of the tension piece 6, and adding more than 15 mm will result in an unnecessarily high cost I.
また、後端縁9の凹入させる深さDは1.5〜3.5m
