[Problems to be solved by the device]

 In the articulator of the hidden slide fastener known in the related art, as in the first example, the mating portion provided at one tip of the articulator having a substantially U-shaped cross section has the mating portion formed up to the tip in both upper and lower parts. When bending a fastener chain, especially when bending it toward the tape side, the side edge of the meshing part near the tape contacts the side edge of the adjacent meshing part, so the fastener chain lacks rigidity and lacks flexibility. Therefore, the bending operation cannot be performed smoothly.

Further, since the connecting portion for connecting the meshing portion and the leg portion is not provided in the tape mounting groove, the lateral pulling strength of the fastener chain is weak, and there is a restriction in terms of use. If you try to raise it, you will have to make the legs thicker, which will result in poor appearance.

Next, in the second example, the size of the meshing portion provided at one end of the U-shaped articulator is made large because the tape mounting groove is horizontally provided in the center of the mesher. However, it is difficult to increase the engagement strength. In addition, since the connecting part that connects the meshing part and the leg part is not provided, the leg part must be formed thick, so that the entire articulator becomes thick and the appearance is bad, and there is no slider guide piece. The slidability of the slider is poor.

This invention was devised to solve the above-mentioned problems, and the articulator of the hidden slide fastener of this invention has a large meshing portion to enhance meshing strength, and the fastener chain is bent. It is also an object of the present invention to provide a concealed slide fastener articulator that can be performed smoothly, and that the articulator does not become thick, has high lateral pulling strength, and has a good appearance.

[0008]

[Action]

 The concealer of the hidden slide fastener according to the present invention has the structure as described above, and is, for example, a slide fastener in which a synthetic resin injector 1 is attached to one side edge of the fastener tape 7 by injection molding. Yes, as shown in FIG. 1, when the slider 17 is slid in the closing direction of the fastener chain 16, the enlarging heads 9 of the lower portion 5 of the meshing portion 2 of the left and right articulators 1 mesh with each other, and Since the fluctuation is restricted by the engagement surface 6, the engagement is surely performed, the fastener chain 16 is closed, and the articulator 1 cannot be seen from the surface.

In the closed fastener chain 16, the wall surfaces 8 of the upper stage 4 of the meshing portion 2 of the left and right articulators 1 only face each other without meshing as shown in FIG. Therefore, the fastener chain 16 can be tilted with respect to the longitudinal direction. To open the fastener chain 16, the slider 17 is slid in the opposite direction to release the meshing state of the lower stage 5 of the meshing portion 2 and the fastener chain 16 is opened.
