2. Description of the Related Art A conventional string adjusting fixture of this type includes an outer cylinder having a string through hole in a radial direction, and a string through hole fitted in the outer cylinder and penetrating in a radial direction of a shaft portion. It has three parts, a fitting that has, and a spring that slides the fitting in the axial direction.
JP-A-62-111414, JP-A-63-272
No. 302 discloses a structure in which a spring is integrally provided below the fitting in order to reduce the number of parts.

[0003] In these string adjusting fixtures, the fitting is pushed into the outer cylinder against the spring, and the string passing hole of the outer cylinder and the thread passing hole of the fitting are aligned with the string passing hole. Through,
By restoring the fitting at a predetermined position by the force of a spring, a stagger is formed between the outer tube and the string passing hole of the fitting to meander and to fix the string.

[0004]

However, since these string adjusting fixtures press the string in the radial direction by the force of a spring, when the string is pulled and green acts,
There is a problem to be solved in that the mating element is pulled down, the meandering state of the string becomes a linear state, the string is easily loosened, the string cannot be securely fixed, and the string fixing function is quickly lost due to damage to the spring. The thickness of the string used for squeezing around the neck of the hat, squeezing the hem of the wear, squeezing for opening and closing various bags such as knapsacks is not constant, and in general, the thickness depends on the object used. Since two kinds of strings of about 6 mm and about 3 mm are used, a string adjustment fixture for thick strings and a string adjustment fixture for thin strings are manufactured, and according to the thickness of the strings. There is a problem to be solved in that it must be mounted separately.
