[0002]

2. Description of the Related Art A belt connecting buckle generally used generally has a saw-toothed engaging claw portion which is rotated by a claw operating plate in which a serrated engaging claw bites into one side surface of a base end portion of the belt. The buckle body can be removed from the belt proximal end away from the proximal end of the belt. Since such a buckle is directly attached to the base end of the belt, there is a problem that it cannot be applied to a reversible belt. In addition, a buckle that cannot be applied to a reversible belt usually supports a plurality of claws or a claw material having the claws integrally with the base end of the belt (for example, see Japanese Unexamined Utility Model Publication No. 6-46508). However, there is a structural problem that the buckle itself cannot be manufactured at low cost.

[0003] Currently, it is desired that the buckle itself can be replaced freely by making the buckle itself a simple decorative plate member and fixing the buckle attachment to the base end of the belt. In this case, the buckle itself can be easily replaced, and at the same time, if the buckle itself can be applied to a reversible belt, the demands of general consumers can be satisfied.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems and demands, and a first object of the present invention is that a buckle itself can be applied to a reversible belt. A second object is to be able to manufacture a replaceable buckle body at low cost.
