  This buckle is formed by notching the guide piece 26 in a certain range in the vicinity of the base 28 of the guide piece 26 provided outside the bent side frame 22 of the female member 2, that is, in the vicinity of the wall surface 28 contacting the tip of the guide rod 9 of the male member 1. A gap 31 that presents a gap is formed. Further, a protrusion 15 that can be fitted into the gap 31 is provided in the recess 14 at the tip of the lower surface of the guide rod 9 of the male member 1.

  The action of this buckle is that when the male member 1 is inserted into the female member 2, the protrusion 15 at the tip of the guide rod 9 of the male member 1 is fitted into the gap 31 formed at the base of the guide piece 26 of the female member 2. Then, the guide rod 9 and the guide piece 26 are overlapped and engaged. Accordingly, rattling of the buckle in the front-rear direction can be completely prevented by the engagement between the gap portion 31 and the protrusion 15. It should be noted that a gap-shaped gap 31 provided in a cutout in the guide piece 26 may be provided on the surface of the guide piece 26.

  In the insertion type buckle of the fifth embodiment shown in FIGS. 15 to 17, the male member 1 has a belt mounting attachment 4 and a base 5 mounted on the side frame 6, and a wide operation piece is provided at the center of the base 5. 10 is projected forward, but has a form slightly different from the operation piece 10 described in the above embodiments. For example, the operation piece 10 is the same as that of the male member 1 of the first embodiment except that the operation piece 10 is provided in a shape protruding from the lower part of the front surface of the base 5 to the front with a certain thickness.

  Since the operation piece 10 is formed thin when the male member 1 is inserted into the female member 2, the buckle can be easily elastically deformed even with a small insertion force. The insertion / removal operation with respect to the female member 2 can be performed very easily.

  As mentioned above, although various embodiment was described about the insertion type buckle of this invention, you may combine not only this form but several kinds of embodiment. For example, the embodiments of FIGS. 10, 11, 13, and 15 can be used in combination, and the buckle of each embodiment can be finished into an insertion type buckle that is extremely thin in structure.

  This invention is an example of the use of a plug-in type buckle. The buckle is thin and can be formed into a small buckle, so it is used for bags as well as clothes in general. In order to operate it, it is necessary to have a condition that can be quickly and easily inserted and removed with one touch. In this respect, it can be said to be an optimal insertion type buckle that satisfies this condition.
