Abstract: A string fastener includes an insertion path for a string; an entrance bar forming one portion of an entrance of the insertion path; an exit bar forming one portion of an exit of the insertion path; a stopper portion pressed by a string between the entrance and the exit and bending an inserted string; an entrance-side guide face portion for the string formed by a curved face or an inclined face, or a combination of these formed in such a way so as to face the entrance bar between the entrance and the stopper portion; and an exit-side guide face portion for a string formed by a curved face or an inclined face, or a combination of these formed in such a way so as to face the exit bar between the exit and the stopper portion.

Abstract: A buckle having an excellent design property is provided. [Solution] In a buckle for a belt in which a socket member and a plug member engage with each other, a buckle 10 is formed by forming the socket member including a front face portion 25 having an approximately flat surface; a back face portion 26 provided in such a way as to face a reverse face of the front face portion 25, and forming an engagement hole 21 with which the plug member engages between the back face portion 26 and the front face portion 25; a pressing piece 28 formed in the front face portion 25 by being divided by a slit 31 formed in the front face portion 25 and pressed for releasing an engagement with the plug member inserted into the engagement hole 21 to be engaged therewith; and a hinge portion 29 formed to be thinner than the pressing piece 28, connecting the pressing piece 28 to the same surface as the surface of the front face portion 25, and serving as a base point for a displacement when the pressing piece 28 is pressed.
