摘要

The present invention relates to a simply structured buckle that reduces the production cost, makes the fastening state firm and reliable, and gives an aesthetic appearance. According to the present invention, a buckle for tightening or loosening a band (4) with the back side having catch projections (2) formed widthwise includes: a buckle body (100) having an insertion hole (102) and an exit hole (104) for slidingly passing the band (4), and a pair of hinge holes (123) formed across the sliding path of the band (4); a plate spring (200) arranged in the buckle body (100) with the leading part positioned in the sliding path of the band (4), the leading part being shaped to slope with the leading end contacting the back side of the band (4) so as to be caught by the catch projection (2) of the band (4) when pulling or pushing the band (4) toward the direction of loosening it and thus to control the slide of the band (4); and a buckle switch (300) having a pivot pressure piece (310) with hinge projections (312, 314) at both ends inserted in the hinge holes (123) so as to be hinged to the buckle body (100) and positioned between the band (4) and the plate spring (200), and an operation lever (320) connected to the pivot pressure piece (310) so as to be exposed to one side of the buckle body (100), characterized in that when the plate spring (200) is pressed by the pivot pressure piece (310), the leading end of the plate spring (200) is separated from the band (4) so as to make the band (4) slide in the loosening direction.
