  • left and right relief recesses 22 are provided in left and right side regions 52 of the upper wing plate 20. Thereby, a gap can be provided between the bottom surface 22a of the escape recess 22 and the pull tab 30.
  • the handle 30 is located between the upper wing plate 20 and the puller 30 that has fallen backward.
  • a non-contact area 59 is provided that does not contact the plate 20.
  • the non-contact area 59 is provided at least in the range from the front edge of the second mounting post 15 to the rear end 22c of the relief recess 22 in the front-rear direction. Note that the range from the position of the front edge of the second mounting post 15 to the position of the rear end 22c of the relief recess 22 can also be referred to as the range within the rear region 57 where the relief recess 22 is provided.
  • the non-contact area 59 extends from the center position of the attachment shaft 33 of the handle 30 to the contact position between the handle 30 and the second protrusion 24b in the front-rear direction (i.e., the range of the reference dimension L2). range).
  • the pull handle 30 may be moved between the left and right shaft supports 23 and the left and right shaft supports. may be in contact with the slider body 10 at a portion other than the second protrusion 24b.
  • the mounting shaft portion 33 of the handle 30 is supported by the left and right shaft support portions 23 of the slider body 10, and the left and right of the handle 30 is The arm portions 32 are supported by the left and right first projections 24a of the slider body 10.
  • the first protrusion 24a on the front side is located closer to the attachment shaft 33 of the handle 30 than the second protrusion 24b on the rear side in a side view of the slider (for example, see FIG. 3). .
  • the handle 30 when the handle 30 is tilted forward, the handle 30 can be held at a larger inclination angle relative to the reference plane 21 of the upper wing plate 20 than when the handle 30 is tilted backward, for example. , the area in which the handle 30 contacts the upper wing plate 20 can be kept small.
  • the handle 30 and the upper wing plate 20 of the slider body 10 can The contact area of the slider can be made much smaller than, for example, a conventional general slider. Therefore, when the slider of this embodiment is subjected to a painting process such as spray painting, and then the painted slider is dried, there is a problem that the pull tab 30 becomes stuck to the upper wing plate 20 due to drying of the paint. Also, it is possible to prevent the problem of the handle 30 remaining on the slider body 10 due to the pull handle 30 being stuck. This makes it possible to reduce coating defects on the slider, thereby increasing the productivity of the slider and the yield of the slider.
  • the left and right relief recesses 22 in the upper wing plate 20 are formed parallel to the left and right direction, and are formed continuously up to the left and right side edges 25 of the upper wing plate 20. . Therefore, when painting the slider by spraying, the paint flowing into the relief recess 22 of the upper wing plate 20 can be easily discharged outward in the left and right direction, making it difficult for paint to accumulate in the relief recess 22 and removing the slider. Can be painted beautifully.
  • left and right relief recesses 22 are continuously formed up to the left and right side edges 25 of the upper wing plate 20, for example, a puller on the slider body 10 whose mounting shaft portion has a different horizontal dimension from this embodiment. Even if a handle (for example, a handle whose attachment shaft portion is long in the left-right direction) is attached, it is possible to prevent or suppress the handle from sticking to the upper wing plate 20 after painting, as in the case of this embodiment.
  • the bottom surface 22a of the relief recess 22 is formed into a smooth concave shape, and is smoothly continuous with the front and rear reference surfaces 21. Furthermore, the relief recess 22 is formed to have a shallow depth relative to the reference surface 21, and its dimension in the front and back direction is reduced to the extent that the contact area between the pull tab 30 and the upper wing plate 20 can be reduced. It is formed as follows. Furthermore, in the slider of this embodiment, when the pull tab 30 is tilted toward the rear opening 17, as shown in FIGS. It can be covered to make it less visible.
  • the slider of this embodiment can provide the same texture as a conventional slider.
  • the slider of this embodiment is attached to the element row of a fastener chain, for example, instead of a conventional slider, it is possible to prevent the user from feeling uncomfortable. Further, it is possible to suppress changes in the influence of slide fasteners on the appearance, design, etc. of zippered products such as clothes and bags.
  • the slider of the embodiment described above is mainly used for a slide fastener in which the element row is formed by a plurality of continuous fastener elements in a coil shape, as described above.
  • the slider of the present invention can be applied to, for example, a slide fastener in which an element row is formed by a plurality of metal fastener elements, or a slide fastener in which a plurality of independent fastener elements are formed on a fastener tape by injection molding of synthetic resin. It may be formed to be used.
  • the upper wing plate 20 is provided with four protrusions 24, including two first protrusions 24a on the front side and two second protrusions 24b on the rear side.
  • the slider body may be formed without providing a protrusion on the front side of the intermediate region, for example.
