Patent Document 1: Japanese Patent Laid-Open No. Hei. No. 2006-468. Patent Document 2: Japanese Patent Laid-Open No. 2008-43568. SUMMARY OF THE INVENTION Problems to be Solved by the Invention Regarding a zipper, in general, it is desirable that the saliva strength is excellent. That is, when the left and right element rows are in meshing state, for example, even if the left and right zipper chain cloths are pulled outward along the width direction of the chain cloth, the lateral pulling force is dedicated to the left and right chain teeth. It does not separate but stably maintains the sprayed state. Here, the skein of the sprocket row is formed as a continuous sprocket 55 in the form of a coil or a continuous sprocket in the shape of a tooth, which is disclosed in Patent Document 1, and is made of, for example, a synthetic resin as described in Patent Document 2 above. The individual sprocket 64 is more flexible than the zipper of the sprocket row on the front and back sides of the zipper chain. However, in the zipper 51 in which the continuous fastener element 55 is mounted as described in Patent Document 1, the fastener element row is formed only on one side of the fastener fabric. Therefore, if the sprocket row or the detaching insert of the zipper 51 receives an upper urging force, and the relative position of the pin 52 and the pin 53 is offset in the front and back directions of the chain, even if the sprocket rows are engaged The insertion portion 52d of the latch 52 is inserted between the upper leg portion 55b of the sprocket 55, and the insertion portion 52d is also offset from the sprocket 55, and 140938.doc -10· is easy to open from the end of the insert side from the sprocket The part is de-chained. On the other hand, the zipper of the synthetic resin-made individual sprocket 64 described above in the above-mentioned Patent Document 2 is symmetrically provided on the front and back surfaces of the zipper chain cloth, even if the key row or the opening insert is subjected to the superscript force, each sprocket Any part of the surface side or the back side interferes with the fastener element on the mouth side of the mouth, whereby the affinity state of the element row can be maintained, so that the occurrence of the chain break can be suppressed. Therefore, compared with the zipper in which the individual fastener elements are arranged on the back surface of the chain cloth table described in the above Patent Document 2, the zipper 51 in which the continuous fastener element 55 is attached as described in Patent Document 1 has a drawback in that the strength of the upper support force is higher. low. In particular, for example, a zipper t of a sprocket row is formed by a continuous sprocket of a coil shape or a zigzag shape, and the detachment insert is used as the detachment insert, and the detachment insert which is excellent in operability as disclosed in the above Patent Document 2 is used. When the opening and closing insert having the embedded body and the pole-rotating support body and arbitrarily selecting the lateral insertion locking operation and the normal locking operation, there is a weak strength against the supporting force on the opening and closing of the insert. Specifically, in the open-release insert 62 described in the above Patent Document 2, the thickness of the inserting plate portion 67a of the inserting body 67 is formed thin as described above. Therefore, there is a drawback in that when the opening and closing insert 62 is urged upward in the back direction of the fastener, the inserting plate portion 67a is easily bent or easily deformed, so that the position of the embedded body 67 is liable to be displaced. Therefore, when the zipper having a coil-like or zigzag-shaped continuous element having a meshing strength lower than that of a separate sprocket made of a synthetic resin is attached, when the side-opening type detaching insert described in the above Patent Document 2 is used, When the fastener element row or the opening and closing of the insert is subjected to the upper floor force, it is easy to open the tooth row and the end of the insertion of the end of the 188 piece. Therefore, in order to productize such a zipper, it is required to increase the meshing strength on the end portion of the element row (the pin) and the end portion of the pivoting support (cylinder pin), and it is particularly required to increase the strength against the upper struts. The present invention has been made in view of the above-described prior problems, and a specific object thereof is to provide a zipper which is formed of a coil-shaped or zigzag-shaped sprocket, so that the flexibility is excellent, and the pin and the barrel of the sprocket row are arranged. The meshing strength at the pin-side end portion is improved, and the chain element row can be prevented from being de-chained even if the opening and closing of the insert is subjected to the upper force.

Thereby, the engaging dog 9c can be accurately engaged with the coil-shaped sprocket 5 which is disposed only on the surface side of the fastener chain*. Further, at this time, the outside of the second fishing portion is located on the surface side (upper side) of the reinforcing member main body (4). In the present invention, for example, the mounting portion for placing the first chain window upper and lower leg portions described in Patent Document 1 may be formed at a position adjacent to the engaging projection 9c of the engagement reinforcing member 9. . Thereby, when the left and right element rows 2 are sprinkled, the engaging protrusions 9e can be accurately engaged (four) with the key teeth E S1 140938.doc -24 - 1378783 5, and the engagement state is further stably maintained. β Next, the operation of closing the slide fastener i of the first embodiment having the above configuration will be described. First, the slider 8 is slid toward the right side of the chain belt 3, so that the opening of the slider 8 abuts against the above-mentioned section which is the lower end. The slider holding portion 12a of the pin 12 is placed. Then, the shaft portion 设^ provided in the latch 11 of the pull button 1 is inserted into the pivoting space l2h formed on the pivotal branch portion 12c of the tubular pin 12, and abuts against the substantially J-shaped inner surface 12i' Thereby, the shaft portion 11b (see FIG. 5) is pivoted by the frame rotation support portion i2c. At this time, in the zipper 1 of the first embodiment, the operation of pivoting the pivotal support portion 12c to support the shaft portion lib of the latch η can be arbitrarily selected from the following two methods. As a first operation method, the shaft portion 11b of the plug 11 is substantially J-shaped from the left side portion ' of the cylinder pin 12, that is, from the gap formed between the pivot support portion 12c and the slider 8 toward the pivot support portion 12c. The inner surface i2i is inserted, whereby the shaft portion lib can be pivotally supported by the pivot support portion 12A by abutting against the substantially j-shaped inner surface i2i. At this time, since the slit 12d' is provided at the end portion of the pivot support portion 12c, the shaft portion 11b can be smoothly pivoted by inserting the pin body portion Ua of the plug pin into the slit 12d. The support portion uc is pivotally supported without causing interference between the above-described latch body portion 11a and the pivot support portion 12c. Then, after the shaft portion lib of the latch 11 is locked to the pivot support portion 12c of the tubular pin 12, the latch n is rotated toward the tubular pin 12 around the shaft portion 11b, whereby the latch body portion na of the plug 11 is used. Inserted into the lower side guide 140938-1010925.doc -25· 1378783 5a above the slider 8, the left and right chain rows 2 are sequentially engaged, so that the zipper 1 can be easily closed 0. The zipper 1 of the first embodiment is closed in this manner. In the middle, as shown in Fig. 6, the J-th hook portion 11c is located between the engaging reinforcing member 9 and the slider holding portion 12a of the tubular pin 12, and 'the above-mentioned first hook portion! The lc is located above the sprocket side end portion of the slider holding portion 12a. Further, the second hook portion 9b of the engagement reinforcing member 9 is firmly engaged with the first hook portion 11C of the plug pin 11, and the engaging projection 9c of the engagement reinforcing member 9 is firmly engaged with the first chain adjacent to the plug pin U. Teeth 5a. Thus, the flexibility of the element rows 2 is not impeded, and the engagement strength of the above-mentioned element rows 2 in the end portion of the side of the insert 10 is greatly increased. Further, when the zipper 1 of the first embodiment is in the engaged state, the zipper chain 4 is pulled outward in the width direction of the chain, so that the sprocket row 2 (especially the sprocket row 2 is opened) The end portion of the side of the insert 1 is subjected to a lateral pulling force, and even if the element row 2 or the opening of the insert 1 is supported by the back of the chain back, the engaging reinforcement 9 and the The engagement of the hook portion He and the first sprocket 5a effectively alleviates the lateral tensile force and the upper urging force, thereby preventing the end of the element row 2 from being uncoupled from the end portion of the insert 10 side. Specifically, in the above zipper cymbal, for example, when the sprocket row 2 is subjected to the lateral pulling force in the width direction of the chain fabric, as shown in FIG. 7, the engaging reinforcing member 9 will be disengaged from the engagement with the second hook portion Uc. Move in direction. On the other hand, however, the side of the cylindrical pin 12 of the recessed portion Ue due to the first hook portion 11c is formed so as to be inclined toward the sprocket row 2 as it approaches the zipper chain cloth 4 having the pin 12; The second hook portion of the inlaid recess lle has an inclined surface corresponding to the inclined surface of the recessed portion (1). Therefore, the reinforcing member moves to the element row 2 along the inclined surface such as 140938.doc -27-1378783. side. Therefore, the engaging projection 9c of the engaging reinforcing member 9 is inserted deeper between the upper and lower leg portions of the first sprocket 5a, so that the engaging reinforcing member 9 interferes with the first sprocket 5a. Therefore, the movement of the twisting reinforcing member 9 is hindered, so that the engagement between the second hook portion 9b of the engaging reinforcing member 9 and the first hook portion Uc of the latch 11 can be prevented, and the reinforcing reinforcing member 9 can be eliminated. The engaging projection 9c is more firmly engaged with the first sprocket 5a. Therefore, even if the element row 2 is subjected to the lateral pulling force, the engagement of the engaging reinforcing member 9 with the pin 11 and the first element 5a does not come off, so that the opening of the element row 2 from the side of the insert 1 can be prevented. The part is de-chained. Further, in the above zipper 1, when the sprocket row 2 or the detachment of the insert entanglement is urged by the direction of the fastener, the engagement strength of the sprocket row 2 away from the end of the insert 1 side Therefore, since the second hook portion 9b of the latch u and the second hook portion 9b of the engaging reinforcing member 9 are formed across the back surface of the fastener fabric of the fastener chain 4, the second hook portion Uc and The mutual interference of any portion of the surface side or the moon surface side outside the second hook portion can maintain the engaged state. Further, even if the position of the second hook portion Uc and the second hook portion are shifted in the back direction of the chain cloth due to the upper supporting force, the second (4) hook portion 9b is arranged to straddle the back surface of the chain cloth. The formation of the hook portion " ', the second hook 9b is not easy to disengage. Therefore, even if the element row 2 or the opening / insert Π) is subjected to the selection force, it can effectively prevent the self-chain row 2 from being happy. The end portion of the insert 10 is unchained. In particular, in the zipper 1 of the first embodiment, when the left and right keys are arranged, the slider 12 is formed on the slider holding portion of the slider 12, and the tab 12g is overlapped with the latch U. The upper side, and the [S} formed by the lower side of the reinforcing member 9

140938.doc -28- 1378783 The insertion portion 9d is fitted into the notch portion Ilf formed on the i-th hook portion Uc of the plug U. Therefore, when the pin ii that is opened from the insert 10 is pushed upward from, for example, the lower side thereof When the upper urging force is applied, the protruding piece 12g formed on the slider holding portion 12a will abut against the latch 11 from the upper surface side, thereby preventing the position of the latch 11 from being displaced with respect to the tubular pin 12, so that the sprocket row 2 can be more reliably prevented from being detached. chain. On the other hand, when the latch u that is opened from the insert 10 is pushed up and pulled from the upper side thereof, the engaging projection 9d of the engaging reinforcing member 9 will abut against the first hook portion 11c from the lower side. " offset from the position of the pin 12, so that the chain element row 2 can be more reliably prevented from being de-chained. In order to open the zipper 1, by sliding the slider 8 rearward, the engaging teeth 5 are pulled apart to abut against the pivoting support body (10). In this state, as shown in Fig. 4, the splicing of the sprocket 5 is separated, and the first! The engagement of the hook portion Uc with the second hook portion % is also released. At this time, the i-th hook portion 11c and the second hook portion 9b are separated from each other by the connection portion of the slider 8. The latch U is then moved so that the shaft portion (10) of the plug (4) is disengaged from the bobbin 12 Within the rotation space 12h, the mortise lock can be separated from the tubular pin η.
