Spring body for slide fastener and slider having the spring body mounted thereon

摘要

The invention provides a spring body for a slide fastener and a slider having the spring body mounted thereon, comprising: the spring body (50) made of a platy material having an opening window portion (51) at the opposite side of a pawl portion (55), and is entirely formed in a substantially lateral C-shape; a spring piece (52) having a figuration such that a longitudinal center portion of the platy material is cut out outward from a side end portion of a main body of the opening window portion (51) to be pulled up at a required height in many steps, the spring piece (52) being disposed between a rear surface of a pull holding body (40) and a pull (30) with elastically contacting them, and the pawl portion (55) being engaged with or released from a portion of a coupling element row by an operation of the pull (30) through an inside of the slider body (20). As a result, it is possible to get the spring body (50) that enables a material and manufacturing cost reduced, to realize a stable and excellent productivity; and a slider with an automatic stop function that enables to acquire and realize the simple and inexpensive structure, miniaturization of the structure, and simple assembly.
