<p>PROBLEM TO BE SOLVED: To provide a slider of a fastener that compensates for the deficiency of a patent document 1 and solves such a phenomenon as the cloth of clothing is sandwiched in a fastener in which the cloth is sandwiched at a position where both upper ends of a slider intersects with elements, when pulling up and closing the slider of a fastener, and as stated in the patent document 1 devised to solve the above, a fan shape is employed by making both upper ends of the slider project aside in order to prevent sandwiching, however, it is needed to make the upper ends of the slider into a convex shape upwardly in order to cover intersection points of the slider and the elements, and the fan shape may not prevent the sandwiching of the cloth sufficiently, and also, the fan shape has such a complex shape that two sides of the slider has not the same shape and its commercialization is difficult.SOLUTION: A slider of a fastener is configured by making a shape of upper both ends of the slider in a heart shape (convex form), and thereby the cloth of clothing may not enter intersection points of elements and the slider (upper both ends), and the sandwiching of the cloth is not caused.</p> |
