Abstract: A belt member includes: a strip member having an elongate shape; a fastener disposed along the longitudinal direction of the strip member; and an opening-closing device that opens or closes the fastener. For reducing a contact pressure of the belt member per unit area, the fastener is opened by the opening-closing device to unfold the belt member into a form of a wide strip so that the width of the belt member is increased. On the other hand, when the fastener is closed by the opening-closing device, the belt member takes a form of a narrow tube so that the width of the belt member is reduced.

Abstract: Provided is a slide fastener that has a flexible fastener tape, exhibits liquid-tightness, and can prevent a gap from being formed in a coupling portion, and a method of producing the slide fastener. An overlay material is formed on a front surface of a fastener tape so that the overlay material formed on a surface of a core member extends beyond a centerline in a front-rear thickness direction of a tape member. When a pair of fastener element rows engages with each other, a tip of an intermeshing head of a fastener element presses the overlay material formed on the opposite core members.
