1. A buckle comprising:
a male member; and a female member into which the male member can be inserted for engagement, wherein the male member comprises a base portion on which a cord member can be mounted, a pair of legs extending from one end of the base portion, and a pair of engaging faces each protruding from a side face of one of the legs on an opposite side of a side on which the pair of legs faces each other and defined on a face intersecting an insertion direction of the male member, and wherein the female member comprises a body portion having an insertion port into which the legs can be inserted on one end, a mounting portion on which a cord member can be mounted on the other end, and a cavity communicatively connected to the insertion port to house the legs internally, a pair of openings each passing through a wall portion of the body portion so as to communicatively connect to the cavity, and engaged faces each defined on an opening sidewall face exposed from one of the openings toward the mounting portion and capable of engaging with one of the engaging faces by a restoring force for elastic deformation of the leg when the leg is inserted up to a predetermined position in the cavity, and when an external force in a direction opposite to the insertion direction is exerted on the male member after the engaging faces of the male member and the engaged faces of the female member are engaged, an engagement width between each of the engaging faces and the engaged faces becomes larger than an engagement width before the external force was exerted due to the elastic deformation of the legs exposed through the openings in an opposite direction to the side on which the pair of legs faces each other. |
