ABSTRACT:
The invention provides a spring body for a slide fastener and a slider having the spring body mounted thereon, comprising: the spring body made of a platy material having an opening window portion at the opposite side of a pawl portion, and entirely formed in a lateral C-shape; a spring piece having a figuration 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 to be pulled up at a required height in many steps, disposed between a rear surface of a pull holding body and a pull with elastic contact, and the pawl portion engaged with or released from a portion of a coupling element row by operating the pull through an inside of the slider body. Consequently, it can get the spring body enabling a material and manufacturing cost reduced, a stable and excellent productivity; a slider with an automatic stop function acquiring and realizing inexpensive structure, miniaturization, and simple assembly.
