The present invention relates to a buckle of the belt which is equipped with saw-toothed coupling means. The present invention provides a buckle comprising a buckle body from the back of which top and bottom walls of buckle frame forming coupling holes are projected on the opposite points; an operating rod which is inserted into the coupling holes formed on top and bottom walls of the buckle frame, wherein a cutout locking member, a locking knob coupled to saw-toothed grooves of a belt, and a push knob for releasing the coupling state of the locking knob are formed on the circumferential surface, a fixed shaft is formed on one end portion, and a spring locking portion is equipped inside thereof; a fixed rod which is coupled to one end portion of the operating rod, wherein a blocking projection inserted into the cutout locking member of the operating rod is formed on the circumferential surface, a fixed rectangular protrusion is formed on one end portion, and a spring locking portion is equipped inside thereof; and a spring for providing the operating rod with rotating elasticity by being inserted into the operating rod.A buckle according to the present invention is more useful compared to, the buckles according to the prior art in that it has made both functions of fastening and unfastening of a belt realized in one component, thereby decreasing numbers of component parts of a buckle and simplifying structure thereof such that production cost can be reduced, productivity can greatly be improved, and unfastening of a belt contrary to a user's intention can be prevented.
