Abstract:
A slide fastener configured in such a manner that a core string is prevented from being caught between upper and lower flanges, that the slide fastener is flexible in an engaged state, and that the slide fastener has improved appearance. The vertical dimension (L4) of the gap (S3) between upper and lower flanges (33a, 33b) of a slider (30) is less than the dimension (L5) of a core string (13a) in the front-back direction thereof when the core string is pressed by a pressure higher than or equal to 5 kgf. Also, fastener elements (15) which form fastener element rows (14) are disposed independently of each other in the vertical direction of the tape members (12) when the fastener elements are in an engaged state. The fastener elements (15) have design sections (16) which are disposed on the front side of the tape members (12) and engagement sections (17) which are disposed on the rear side of the tape members (12) and mesh with adjacent fastener elements (15). In the engaged state, the design sections (16) are disposed so as to be separated from adjacent design section (16) and have a curved hemispherical shape.
