However, the metal buckle of the above-described prior art has sufficient strength, but the number of components is large and the structure is complicated, and the metal as a whole is also a considerable weight.

Thus, for example, the use of such a buckle for an animal's collar is an excessive burden for the loaded animal. In addition, in the case of a leather bag or other personal belongings, although the necessary strength can be obtained, it is not suitable in terms of weight.

In addition, if the number of components is large, the cost of purchasing and managing components is high, and the number of assembly hours is also large, which is inevitably reflected as a rise in commodity prices.

Therefore, the present invention has been made in an effort to solve the problem of such a conventional metal buckle, and an object thereof is to provide a buckle having a sufficiently necessary strength, a small number of members, and being inexpensive and lightweight.

In order to solve the above problems, the buckle of the present invention has the following configuration.

A buckle for inserting an insertion piece protrudingly disposed on a male member into an insertion opening of the female member and coupled to the belt body, the insertion piece of the male member having a pair of engaged portions, the female member having a metal wire having elasticity Forming a pair of arm portions that are bent and protruded from both ends of the base portion, and the pair of arm portions are integrally formed by bending to form a pair of engaging portions by which the arm portions are formed The mutual spacing is expanded and contracted by elastic deformation, and can be disengaged from the engaged portion of the insertion piece.

As described above, since the female member of the buckle of the present invention includes the fastening portion and only one elastic metal wire is bent, the constituent members are less expensive and lighter than the former, and the material cost and the production cost are also very high. Cheap. Further, since the mother member is formed of a metal wire, sufficient strength can be exhibited.

Further, in the above configuration, one of the pair of female members may be intersected with each other at an intermediate portion of the engaging portion.

Thereby, the operation of pressing the pair of arms from the outside can be converted into an effect of expanding the interval between the engaging portions. Further, when the insertion piece of the male member is held in a cross shape in the thickness direction in the range in which the arm portions intersect each other, the state in which the male member and the female member are engaged with each other is less swayed and stabilized.

Further, in each of the above-described configurations, the one of the pair of female members may have the inner edges of the respective curved portions facing each other, and the space surrounded by the pair of engaging portions may constitute the insertion opening of the female member. .

In this case, the engaging portion can double as the insertion opening, and since the insertion piece of the male member can be held by the insertion opening that is surrounded by the engaging portion, the fastening state of the male member and the female member is also stabilized. .

Further, the female member is housed in a cover body having an insertion opening into which the insertion piece of the male member is inserted, and a housing portion that communicates with the insertion port to house the female member, and is provided with the cover body The outer side of the operation unit that releases the engaged state of the engaged portion and the engaging portion is released.

Thereby, the female member can be protected from the external impact or the like, and the design is also better than that of the female member only composed of the metal wire.

Further, a belt attachment portion for connecting to the belt body is provided on the cover body, and the base portion of the parent member can be fitted to the belt attachment portion.

Thereby, the fixing of the cover body and the female member is made sure and easy. Further, since the base of the female member can also constitute a part of the belt mounting portion of the cover body, the cover body and the female member can be attached with sufficient strength with respect to the belt body.

According to the present invention, it is possible to provide a buckle having sufficient strength, a small number of members, and being inexpensive and lightweight.

Hereinafter, embodiments of the present invention will be described based on the drawings. In this embodiment, the buckle of the present invention is applied to an animal collar.
