In a buckle of a type in which an insertion body (5) of a male member (2) is inserted into a housing (4) of a female member (1), the male member (2) is comprised of the insertion body (5) and a belt attaching frame (7), the insertion body (5) and the belt attaching frame (7) being formed separately while a base end of the insertion body (5) and the belt attaching frame (7) are linked with each other so as to be freely rotatable. and the female member (1) is comprised of the housing (4) and a belt attaching frame (6), the housing (4) and the belt attaching frame (6) being formed separately while a front end of the housing (4) and the belt attaching frame (6) are linked with each other so as to be freely rotatable. Consequently, the buckle can readily fit a configuration of a surface of a product to be used, particularly a curved state thereof, thereby achieving a stable tightening. |
