[0040] in accordance with Figures 1 to 9 In the zipper slider with automatic locking device of the first embodiment shown, the main body 1 and the pull tab 8 are formed by die-casting method with metal such as zinc alloy, aluminum alloy, and the cover 7 is formed by stamping steel sheet. The slider with an automatic locking mechanism includes three parts, namely, a main body 1 , a cover 7 and a pull tab 8 . The cover 7 is equipped with locking claws 30 as a locking mechanism, and by operating the pull tab 8, the locking claws 30 can be inserted between the left and right zipper elements 40 arranged in a straight line. A pull tab 8 prepared by a user may be used as the pull tab 8 used here. Therefore, the slider with the automatic locking device can be easily assembled by hand.

[0041] like figure 1 As shown, in the slider body 1 , the upper wing plate 2 and the lower wing plate 3 are connected with rhombus blocks, and flanges 5 are formed on the two side edges of the upp...
