Abstract

Une fermeture à glissière (1) selon la présente invention comprend : une paire d'un premier élément de demi-chaîne (11) et d'un second élément de demi-chaîne (12) ; un curseur (20) ; et un premier élément d'arrêt (30) et un second élément d'arrêt (40) qui délimitent des positions de limite de coulissement du curseur (20). Une colonne d'accouplement (24) dans un corps (21) de curseur du curseur (20) a une partie conique (24c) dans laquelle la dimension de largeur de la colonne d'accouplement (24) diminue progressivement vers une ouverture arrière. Lorsque le curseur (20) est positionné à une position limite de coulissement, le premier élément d'arrêt (30) et le second élément d'arrêt (40) sont positionnés à l'intérieur d'une région de réception (29) qui réalise un recouvrement d'une position d'extrémité côté pointe d'épaulement de la partie conique (24c) de la colonne d'accouplement (24) dans la direction longitudinale jusqu'à la position de l'ouverture arrière, et les deux éléments d'arrêt viennent en contact l'un avec l'autre. Cette configuration permet d'avoir une qualité d'aspect améliorée de la fermeture à glissière (1) dans un état fermé, étant donné que des éléments de fixation d'élément (13) situés sur la gauche et la droite et s'étendant de la pointe d'épaulement du curseur (20) sont maintenus dans un état parallèle ou presque parallèle.
