1. A buckle, comprising:
a pair of side frame portions; a first crossbar and a second crossbar extending between the pair of side frame portions, the first crossbar being adapted to be wound by a belt body; and a fastening portion located on the first crossbar of the buckle for fastening the belt body wound around the first crossbar, a clamping member rotatably supported in the side frame portions, and having a free end portion for clamping the belt body between the free end portion and the fastening portion of the first crossbar in a first position wherein the free end portion is most closely contacting with the first crossbar and releasing the belt body in a second position wherein the free end portion is separated from the first crossbar; and a holding device for deforming the clamping member when the clamping member receives a rotation force in a direction of separating the free end portion from the first crossbar, wherein the holding device is a protruding portion formed on each of the side frame portions, and having a first taper portion directed toward the first crossbar, a second taper portion directed toward the second crossbar, and a protruding end protruding furthest from an outside surface of the side frame portion and disposed between the first and second taper portions, and the protruding portion abuts against a side portion of the clamping member so that when the clamping member rotates from the second position to the first position, the clamping member elastically deforms to slide over the protruding end and the first taper portion urges the clamping member to press the free end portion against the belt body, and when the clamping member rotates from the first position to the second position, then clamping member elastically deforms to slide over the protruding end and the second taper portion forces the clamping member to rotate in the direction of separating from the first crossbar. |
