Title:
METALLIC ELEMENT AND SLIDE FASTENER
Document Type and Number:
WIPO Patent Application WO/2021/070345
Kind Code:
A1
Abstract:
A pair of leg parts (31, 32) are respectively provided with core string pressing surfaces (62, 64) that, as the distance from restraint surfaces (61, 63) becomes greater, become gradually inclined so as to approach each other. The core string pressing surfaces (62, 64) respectively extend from the restraint surfaces (61, 63) until reaching base end sections (38) of the leg parts (31, 32). The thicknesses (T31, T32) of the leg parts (31, 32) in the thickness direction of a fastener tape (10) gradually increase from free ends (39) of the leg parts (31, 32) toward the base end sections (38) in accordance with at least the inclination of the core string pressing surfaces (62, 64).
