Abstract: The invention provides a fastener slider, wherein the fastener element comprising an element main body constituted of a base portion attached to a fastener tape, a neck portion and an engaging head portion continuous from the neck portion and expanding in a tape length direction and stiffening means provided on the element main body, allowing a fastener stringer to bend when the elements are separated and inhibiting the fastener chain from bending when the elements are engaged in a stiffening condition, the stiffening means having a first firm contact face making firm contact with mating stiffening means when the elements are engaged and a second firm contact face making firm contact with a partial surface of the engaging head portion of the fastener element when the elements are engaged, thereby the slide fastener having a rigid, linear or curved rod-like configuration when fastener elements are engaged, allowing it to deform in multiple directions.

Abstract: A fastener wherein right and left side edge portions can be engaged using a magnetic force, and which can be applied preferably for plastic article such as clothes and further prevented from being opened carelessly even if a lateral pulling force is applied when right and left elements are engaged.
