A slide fastener of the present invention includes: a first fastener stringer; a second fastener stringer; and a slider which couples or separates the first and second fastener stringers, in which the second fastener stringer separated from the slider is inserted into the slider wherein the first fastener stringer and the second fastener stringer are coupled in a vertical direction. Accordingly, a row of fastener elements of the second fastener stringer separated from the slider is inserted into the slider by first and second fastening members when a fixing pin and an insertion pin are coupled in a vertical direction, and as a result, the coupling operation is convenient.

Fastener element of slide fastener has an intermediate portion including bent or curved portion between a terminal portion and a base portion. The intermediate portion has an engaging protrusion and an engaged recess which are respectively protruded and recessed on an axis that matches a movement direction of the slider. In an orthogonal direction orthogonal to the axis, a first distance between the axis and the terminal surface of the terminal portion is less than a second distance between the axis and the base end surface of the base portion.

Provided is an aluminum alloy fastening member having a novel chemical conversion coating as a colored coating, a fastener chain, and a method for producing the aluminum alloy fastening member. The aluminum alloy fastening member includes a chemical conversion coating containing manganese as a component element, and the chemical conversion coating satisfies hue ranges of −3≤a*≤12, −5≤b*≤35, and 45≤L*≤80 in a CIELAB color space as defined by JIS Z 8781-4 (2013).

The subject of the invention is a magnetically closing zipper device, without slider, which is equipped with two chain rows including chain links, the material of the links is magnetic metal, the link comes into contact with the link in the same chain row and adjacent to it in such a way, that by magnetic attraction, the north pole is connected to the south pole and the south pole is connected to the north pole, the zipper structure is connected to the target material directly or by a ribbon, the links are connected to each other with a curved surface.

A convenient and quick-release textile, a quick-release slide fastener being provided on the textile includes: a tooth easy-release region being provided on the teeth of the quick-release slide fastener. A pulling member is provided beside the tooth easy-release region. Quick positioners having a mutual positioning function are further provided on both the textile and the pulling member correspondingly. The quick positioner provided on the textile and the quick positioner provided on the pulling member are located on a same side of the quick-release slide fastener, or separately on two sides of the quick-release slide fastener. In this way, the pulling member textile is held easily and covers the tooth easy-release region, thus preventing the tooth easy-release region from separating due to the impact of the unnecessary external force.
