At this time, the lengths of the slit portions 63a and 63b in the front-rear direction are set such that the teeth of the third element teeth 3 lc are not in contact with the upper and lower flanges 54L and 55L. Further, the gap G3 (see Fig. 3) of the fastener insertion passage 59 in the notched portions 63a and 63b is set to be larger than the thickness H of the fastener element 31 (see Fig. n). As a result, when the above-described 3rd sprocket 31c is pulled toward the left side while rotating, the rotation can be smoothly performed. Further, the lower slider 90 has a mirror-symmetric structure in which the upper slider 40 is reversed left and right with respect to the center line CL in the width direction of the guide post 53. Therefore, as shown in Fig. 5, the upper side slider and the lower side flanges 54L, 55L or the cutout portions 63a, 63b of the lower side slider 90 including the projections 62a, 62b and the straight portions 54a, 55a are attached to the upper side slider 4'. Same on the left side. Moreover, the reverse opening and closing member 13 is when the lower side slider 90 is in contact with the stopper 14a at the lower end portion of the cylinder pin 14, and the upper side slider 40 is in contact with the state of the lower side slider 9〇, The stopping pawl 71 of the upper slider 40 is disposed at a position that avoids the upper surface of the tubular pin 14, that is, does not contact the tubular pin 14.

In the zipper 10 configured as described above, the lateral pulling force toward the outer side in the width direction is applied to the pair of right and left chain shackles 1L, 11r which are upper side than the upper side slider 40 from the state shown in FIG. Referring to Fig. 7), the first element 31a (sprocket 31) which is located closest to the introduction port 56 side in the element guide path 58 of the separation side chain band 11L and which is not engaged with 158442.doc -13 - 201244659 The surfaces of the upper and lower flanges 54L and 55L are respectively abutted against the inclined surfaces 61a and 61b of the upper and lower flanges 54L and 55L (see FIG. 11), and the gap between the upper and lower flanges 54L and 55L is extended (see FIG. 12). The plate 51 and the lower blade 52 are deflected from the left side of the guide post 53 (see Figs. 8 and 9), and are released from the slider 40. At this time, the second i-sprocket 3 i &, the second sprocket 3 lb is also detached from the flat portion 54a' 55a of the upper and lower flanges 54L, 55L in the same manner as the first sprocket 3 la Out. Further, the third sprocket 31c is also blocked from the upper and lower flanges 54L and 55L without being blocked by the projections 62a and 62b (see Fig. 10). Therefore, the de-chaining operation for separating the separated side chain belt 11L from the slider 4 is smoothly performed without stopping in the middle. On the other hand, even if the upper or lower sliders 40, 9 are strongly subjected to a twisting action such that the slider 75 is rotated counterclockwise on the slider body 50, the third element 3 1 c can be prevented. The protrusions 62a, 62b of the upper and lower flanges 54L, 55L are touched, causing the left chain insertion passage 59 to straddle the sprocket 3 of the left and right chain belts 11L, 11R, thereby preventing the slider 4, 9〇 Stops obliquely. Further, in the present embodiment, the separation side chain belt 11L is separated from the lower side slider 9A, and the pair of left and right chain belts 11L and 11R which are lower than the upper side slider 40 are continuously applied in the width direction. The lateral tension of the outer side moves the upper slider 40 to the upper side. Then, as shown in FIG. 14, in the state in which the upper slider 4 is positioned by the upper stopper portion 12, a lateral pulling force is further applied, whereby the third sprocket 3 1 c is brought into contact with the upper and lower flanges. The second sprocket 3 1 b of 54L and 55L is a fulcrum and is pulled toward the left side while rotating. At this time, the corner portion of the third sprocket 31c is located in the cutout portions 63a, 6 and not with the upper side and the lower side 158442.doc

Thereafter, the second sprocket 3 lb abuts against the inclined surfaces 61a and 61b of the upper and lower flanges 54L and 55L, respectively, and opens the gap between the upper and lower flanges 54L and 55L to open the upper wing. The plate 51 and the lower blade 52 are deflected from the upper side of the guide post 53 so as to be deflected from the upper slider 40 (see Figs. 15 to 17). Further, the J-chain teeth 31a are also released from the upper slider 40 substantially simultaneously with the second sprocket 3 1 b coming out of the upper slider 40. As described above, according to the slide fastener 1 of the present embodiment, the opposite side of the upper left side of the slider main body 50 and the lower side flange 54L' 5 5L are provided with projections 62a, 62b at the rear end side portion thereof. Therefore, the third sprocket 31c of the separated side chain belt 11L on the fitting side of the sliders 40, 90 is not easily detached from the chain insertion passage 59, thereby preventing the upper side or the lower side due to the twisting action of the pull tab 75. The side sliders 40, 90 are stopped obliquely with respect to the key band. Further, the opposite sides of the upper left side and the lower side flanges 54L, 55L of the slider main body 5 are respectively provided with parallel portions 54a, 55a which are parallel to each other except for the positions in the front and rear directions of the projections 62a, 62b. That is, in the case where the slow chain is facilitated, the respective fastener elements 31 in the element guide path 58 are also sequentially inserted through the chain insertion path 59, thereby preventing the disconnection operation from being stopped in the middle. Therefore, the sprocket 31 is prevented from being scratched by a simple configuration, and the separated side chain belt 11L can be easily separated from the upper or lower side sliders 4, 90. Further, the gap upper and lower dimension G2 of the gap insertion passage 59 in the front and rear direction positions including the projections 62a and 62b is larger than the gap upper and lower dimension g of the fastener insertion passage 59 on the right side of the slider body 5〇, Therefore, it can be prevented from taking off
