Reference numeral 12 denotes a belt end fixing tool, in which both ends of the fixing tool main body 14 in which the belt hanging frame hole 13 is bored, the shaft support tube 15 is bent and formed at positions on both sides of the shaft tube 11. It is composed.

16 is a shaft, which is composed of a central shaft 17 and a cylinder shaft 18, and
17 has a support projection shaft 19 at one end and a semicircular shaft portion 20 having a cross section at the other end. The cylinder shaft 18 has a notch 21 for engaging the rotation stopper 7 at one end, and the other end has the above-mentioned cross section. The semi-circular shaft portion 20 is a semi-cylindrical portion 22 which is inserted, and the cross-section semi-circular shaft portion 20 is wound around the semi-circular shaft portion 20 in a non-rotational manner. It is assembled through.

Each member configured as described above engages the shaft cylinder 11 of the belt pressing member 8 and the shaft support cylinder 15 of the fixing device main body 14 on the same axis, and attaches the spring 23 to the spring of the shaft cylinder 11. Window 11a
It is in a state of being arranged and maintained in the section.

Then, the central shaft 17 is inserted from one side so that the spring 23 is non-rotatably wound around the semicircular shaft portion 20 in cross section, and then the cylindrical shaft 18 is inserted from the other side.
From the semi-cylindrical portion 22 side into the shaft support cylinder 15 and the shaft cylinder 11,
Engage with the semi-circular shaft portion 20 of the central shaft 17 inserted earlier,
It is assumed that the shaft 16 is shortened in the axial direction.

In order to mount the belt pressing member 8 and the belt end fixing member 12 connected by the shaft 16 to the buckle body 1, the belt pressing member 8 is pressed by the spring 23 against the back surface of the front plate 2 of the buckle body 1. In this state, the support projection shaft 19 of the shaft 16 is fitted into the support hole 6a, and the end of the cylinder shaft 18 having the notch 21 is fitted into the other support hole 6b to engage the notch 21 with the rotation stopper 7. It is done by combining.

The buckle according to the embodiment of the present invention constructed and assembled as described above is fixed by sewing like a conventional buckle by passing one end of the belt through the belt hanging frame hole 13 of the belt end fixing tool 12 to bypass it. Then, the other end is used by inserting it between the back surface of the front plate 2 of the buckle body 1 and the belt pressing tool 8.

In this case, when the belt end fixing member 12 is tilted with respect to the buckle main body 1, the belt insertion interval is opened, and the belt is in a state of freely sliding.
By the action of 23, the rubber coating 10 of the belt pressing member 8 presses the belt, and the belt slides in the tightening direction but presses the belt surface in a wedge state in the loosening direction to prevent the loosening. become.

In the above embodiment, the shaft end supporting portions 5a and 5b are formed by bending the side plates 3a and 3b of the buckle body, but separate pieces may be formed by welding, and the shaft 16 shortening means. May be a thin shaft having an axial groove instead of the semicircular shaft portion 20 in cross section, or may be a thin shaft having a hole for fixing one end of a spring formed therein and a cylindrical shaft. .

(Advantageous effects of the invention) In the buckle of the present invention, the belt end fixing member and the belt pressing member are rotatably supported on both side plates mainly of the buckle by using a shaft around which a spring is wound. In a buckle that is adapted to bite the belt by pressing against the back surface of the buckle-based front plate by a spring, on the inner surfaces of both side plates of the buckle main body, while forming a shaft end support portion that prevents rotation of the shaft, Since the shaft is configured to be shortened by compressing the spring in a non-rotating state so that both ends thereof are supported by the shaft end supporting portion, when the belt end fixing member 12 is tilted with respect to the buckle main body 1, the belt is The insertion interval is opened, and the belt is in a state of freely sliding, and if it is returned to its original position, the rubber coating 10 of the belt pressing tool 8 presses the belt by the action of the spring 23. Tighten Since also loosened direction slides in the direction to prevent loosening to press the belt surface in terms wedge state, tightening of the belt, loosening is reliable, there is no failure simple configuration. Further, with the above structure, it is not necessary to caulk the shaft, and the supporting holes of the shaft are hidden by the both side plates mainly of the buckle, so that the supporting hole is not exposed on the outer surface of the side plate and the shaft does not project.

Therefore, the work of penetrating both ends of the shaft around which the spring is wound into both side plates mainly of the buckle as in the conventional case is not necessary, and the assembly can be done easily, and various kinds of protrusions caused by the projection of both ends of the shaft can be achieved. Inconvenience, for example, when operating the buckle, there are drawbacks such as cuts and fingers on the fingers and the fact that the fabric and the like are caught and damaged, and that the appearance of the shaft end protruding from the side plate is bad and the appearance is bad as an accessory. It is possible to provide a buckle that is resolved and has a good appearance in which the shaft end does not project.
