摘要： There is provided a slide fastener with a separable stop including a retainer pin and a separable pin. The separable pin has a projection configured to be engaged with a fastener element. The slider includes a raised portion. For example, the raised portion extends on a lower surface of the upper plate rearward from a periphery of the guide post and is raised from the lower surface of the upper plate toward the lower plate. The raised portion of the slider and the separable pin have respective contact portions configured to come in contact with each other in a moving direction of the slider. At least one of the contact portion of the raised portion of the slider and the contact portion of the separable pin is provided with an intersecting portion obliquely intersecting with the moving direction of the slider.

摘要： A slide fastener tape member includes a tape body and a core string portion disposed at a tape side edge portion of the tape body along a length direction. The core string portion is formed by fixing a string member at the tape side edge portion along the length direction by machine sewing. The string member is fixed linearly such that at least one thread used for machine sewing crosses while contacting an outer peripheral surface of the string member without being pierced by a needle thread of machine sewing. Thus, since the core string portion can be easily provided by fixing the string member to the tape body having desired properties at a later stage, the value-added tape members can be easily manufactured at a relatively low cost.
