  • the step of caulking and fixing the puller 5 to the puller holding portion 31 can be performed after the stop pawl body 6 is caulked and fixed to the slider body 2, but the stop pawl body 6 is caulked and fixed to the slider body 2. Since it is necessary to hold the handle 5 separately in the process, it is preferable to fix the handle 5 to the handle holder 31 first from the viewpoint of workability.
  • FIG. 6 schematically shows a cross-sectional view (a) of a portion not chamfered as indicated by a dotted line E in FIG. 6 and a cross-sectional view (b) of a portion chamfered as indicated by a dotted line F.
  • the chamfer radius of the R chamfered portion 64 can be appropriately set in consideration of the slider size and the stress reduction effect, but is preferably set in the range of t / 2 to t / 3 (t is the thickness of the plate thickness). Now refer to FIG.
  • the stop claw body 6 is caulked and fixed from the state shown in FIG. 8A (semi-finished slider) before the stop claw body 6 is caulked and fixed by the caulking column 34.
  • the right and left caulking pillars 34 are bent inward, it is possible to avoid the caulking pillar 34 with which the stop claw body 6 is in contact with the ridge corner of the stop claw body 6 in the initial stage of bending. . Since the crimping column 34 is bent to some extent and then comes into contact with the stop claw body 6 from above, fluctuations in the contact position between the left and right crimping columns 34 and the stop claw body 6 can be suppressed. For this reason, it becomes difficult to produce a caulking defect compared with the past.
  • the R chamfered portion 64 is formed in the stop claw body 6 in the second embodiment, when the inner side surface 41 of the crimping pillar 34 comes into contact with the stop claw body 6 as shown in FIG. It can slide on the R chamfered portion 64 and can be caulked smoothly. Therefore, the stop claw body 6 is less likely to be caught by the crimping column 34, so that the stop claw body 6 can be easily arranged to a predetermined position corresponding to the degree of bending of the crimping column 34. Furthermore, since the local stress with respect to the contact surface with the stop nail
  • the first R chamfered portion 64 extends from the flat portion 65 to the upper surface of the bent portion 66.
  • the stop claw body 6 is made of a single flat plate material. Generally, the shape of the stop claw body 6 is punched from the plate material, and the ridge angle that contacts the crimping column 34 of the flat stop claw body 6 is set to R. After the chamfering process, bending is performed, and the hook part 62 and the cover part 63 are formed. At this time, by forming the R chamfered portion over the plastically deformed portion of the bent portion 66, the R chamfered portion can be stably formed when bending is performed in order to form the hook portion 62.
  • FIG. 9 is a perspective view illustrating the structure of the slider body 2 according to the slider of the third embodiment. Since the basic structure is the same as that of the first embodiment, duplicate description will not be made.
  • the difference between the slider body 2 used in the slider of the second embodiment and that of the first embodiment is the relationship between the insertion groove 32 and the caulking post 34.
  • FIG. 10-1 is a diagram corresponding to the cross-sectional view taken along the line AA ′ of FIG. 3 in the slider according to the third embodiment of the present invention.
  • FIG. 10-2 is a diagram corresponding to the slider according to the third embodiment of the present invention. 3 corresponds to a cross-sectional view taken along line BB ′ in FIG. 3, and
  • FIG. 10-3 corresponds to a cross-sectional view taken along line CC ′ in FIG. 3 in the slider according to Embodiment 3 of the present invention.
  • the shortest portion of the insertion groove 32 in the left-right direction is the portion sandwiched by the raised portions 35 and the front end 32a of the insertion groove.
  • the left and right inner side surfaces 41 of the pair of caulking posts 34 determine a movable distance in the left-right direction of the stop claw body 6 inserted into the insertion groove 32 among the left and right side walls 39 of the insertion groove 32 (
  • the portion sandwiched between the raised portions 35 and the front end 32a) of the insertion groove are present on the left and right outer sides, respectively.
  • each inner side surface 41 of the caulking column 34 is on the same plane as the side wall 39 of the insertion groove 32 existing on the lower side of the caulking column 34.
  • the distance D 1 ′ between the caulking pillars 34 is equal to the width d B ′ of the insertion groove at that location, the right and left caulking pillars 34 are bent inward to fasten and fix the stop pawl body 6. At this time, it is possible to avoid the crimping column 34 from coming into contact with the ridge corner portion of the stop claw body 6 in the initial stage of bending.
  • FIG. 11 shows the state of the crimping column 34 when the crimping operation is finished in the slider according to the third embodiment.
  • the left and right inner side surfaces 41 at the bases of the pair of caulking posts 34 are respectively shorter than the portion having the shortest lateral width of the insertion groove 32 (the portion sandwiched between the raised portions 35 and the front end 32a of the insertion groove). Exists on the left and right outside.
  • the third embodiment does not have the puller engagement / disengagement portion 36 that removably engages the puller 5 when the puller 5 is tilted to the rear opening 27 side. Accordingly, the handle main body 51 need not have the left and right cantilever locking pieces 55.
  • the handle 5 is caulked and fixed by the handle holding portion 31 protruding from the upper blade 21 of the slider body 2, but the stop claw body 6 is caulked and fixed to the slider body 2.
  • the handle 5 may be of a type attached to the slider body 2 by a cover body (not shown) fitted to the slider body 2.
  • a stepped portion 38 at the boundary between the side wall 39 of the insertion groove and the inner side surface 41 of the crimping column, but the inside of the crimping column from the side wall 39 of the insertion groove so that the stepped portion 38 is eliminated. You may form by the taper surface which continues over the side surface 41.
