Abstract: [Problem] To provide a slide fastener chain and a slide fastener, which have a small curvature radius and which have flexibility enabling the slide fastener chain and the slide fastener to be smoothly bent. [Solution] A slide fastener chain (1) comprises: a pair of fastener tapes (2); and elements (3) affixed to the facing edges (21) of the fastener tapes (2) at a predetermined pitch. The slide fastener chain (1) is characterized in that: the elements (3) each have bases (31a, 32a) affixed to a fastener tape (2) and each have heads (31c, 32c) protruding from the bases (31a, 32a) and engaging with facing elements (3); and the thickness (t) and pitch (p) of the elements (3) satisfy the following expressions (1) and (2).

Abstract: There is provided a side fastener chain. A plurality of elements are fixed on each of opposing edge portions of a pair of fastener tapes at a predetermined pitch. The elements include a base portion and a head portion. A ratio (Rt) of the sum dimension of a first partial thickness, which is measured from an upper surface of each element to an upper surfaces-side apex of the respective edge portion, and a second partial thickness, which is measured from a lower surface of the element to a lower surface-side apex of the edge portion, to a thickness of the element satisfies the following equation: 40%≦Rt. A ratio (Rtl) of the thickness of the element to the entire length of the element satisfies the following equation: 0

Abstract: Provided is an injection-molded resin button, which does not crack or is unlikely to crack at attaching the button to a fabric. This invention relates to a button including a button body having a through-hole at the center thereof. The button body of the button includes a left half part and a right half part, which are segmented left and right by a virtual straight line passing through a gate position, on the button body, corresponding to a gate of a mold for molding the button and the center of the button body. The button body includes one or more concave portions or one or more convex portions on an outer surface of the button body. The button is characterized in that the concave portions or the convex portions are provided asymmetrically in the left and right half parts. The button body includes a nonlinear weld line at least on the outer surface.
