  • the left front stop portion 70m and the right front stop portion 70n are configured to overlap each other when they are lined up side by side. Even in such a case, the same effect as that of the above-described embodiment can be obtained.
  • existing manufacturing equipment can be used effectively regardless of an increase in the total width when the left and right front stop portions 70 are lined up side by side.
  • the total width when the right front stop portion 70m and the left front stop portion 70n are arranged side by side is large, and it is necessary to adjust the width of the alignment jig, etc. In the case of this embodiment, the necessity is reduced at least.
  • a stepped portion R14m is provided in the inner portion of the left front stop portion 70m, and a stepped portion R14n is provided in the inner portion of the right front stop portion 70n.
  • the step portion R14m is a portion that should face the upper wing plate 81 and the connecting column 83 of the fastener slider 80.
  • the step portion R14n is a portion that should face the lower wing plate 81 and the connecting column 83 of the fastener slider 80.
  • the horizontal plane S14n1 of the step R14n is arranged on the horizontal plane S14m1 of the step R14m, and the total when the right front stop 70m and the left front stop 70n are arranged side by side. The width is reduced.
  • FIG. 22 is a schematic diagram of the front end portion of the slide fastener, showing a state after the front stop portion is press-fitted into the fastener slider, where the left front stop portion is connected to the connecting column and the left lower flange portion. The right front stop portion is deformed along with the press-fitting between the connecting column and the right lower flange portion.
  • FIG. 23 is a schematic cross-sectional view showing a state in which the right front stop portion of the slide fastener is press-fitted into the fastener slider, and shows a cross section taken along the dotted line SL23 of FIG.
  • the front stopper 70 has a fin portion 107 that can be disposed between the lower flange portion and the upper flange portion. Even in such a case, the same effect as that of the above-described embodiment can be obtained. By adding the fin portion 107, the front stopper 70 can be more firmly fixed to the fastener tape 51.
  • the right front stop 70n includes a right fin portion 107n that can be disposed between the right lower flange portion 85n2 and the right upper flange portion 85n1.
  • the left front stop portion 70m has a left fin portion 107m that can be disposed between the left lower flange portion 85m2 and the left upper flange portion 85m1.
  • the fin portion 107 is sufficiently thinner than the front stop portion 70 and can be disposed in the gap between the upper flange portion and the lower flange portion.
  • the left fastener element 60m has a left fin portion 108m that can be disposed between the left lower flange portion 85m2 and the left upper flange portion 85m1.
  • the right fastener element 60n has a right fin portion 108n that can be disposed between the right lower flange portion 85n2 and the right upper flange portion 85n1.
  • the fin portion 108 is sufficiently thinner than the fastener element 60 and can be disposed in the gap between the upper flange portion and the lower flange portion.
  • the fastener slider (80) is slid to the front side which is the front stop portion (70) side by a first force, and the front stop portion (70) is partially inserted into the fastener slider (80), The fastener slider (80) is moved to the front side by a second force larger than the first force, and at least between the connecting column (83) and the flange portion (85) of the fastener slider (80).
  • the use method of a slide fastener which press-fits one said front stop part (70).
  • Release of the locked state of the fastener slider is not achieved only by directly displacing the fastener tape.
  • the fastener tape may be displaced by pulling the garment on which the fastener tape is sewn, thereby releasing the locked state of the fastener slider.
  • the fastener slider may be of a claw type.
