[Problems to be Solved by the Invention] The resin stopper is generally of the type described in Patent Document 1, and has a portion that can be inserted into the slider. By partially inserting the resin stopper into the slider, the amount of resin used in the resin stopper can be reduced, and the partial thickness can be made equal to the thickness of the fastener element. However, in the case where the shape of the fastener element is desired to be thinned, the resin stopper of this configuration is not necessarily optimal. For example, the fixing force of the resin stopper for the core rope of the zipper chain cloth is lowered. Moreover, the durability of the zipper chain cloth on the left and right sides of the horizontally stretched zipper chain is also lowered. In view of these problems, the case where the resin stopper is swollen to the extent that it cannot be inserted into the slider has also been studied. However, there is generally no allowable difference in thickness between the zipper teeth and the stops disposed adjacent thereto. The inventors of the present invention have newly discovered the significance of ensuring the restraining force for stopping the stop of the slider and suppressing the increase in the thickness of the stopper.

More specifically, the plurality of first fastener elements 210 are fixed to the first core 115 of the side edge portion of the first fastener chain 110. The second fastener tape 320 includes a second fastener chain 120 and a second fastener element 220. More specifically, the plurality of second fastener element teeth 220 are fixed to the second core string 125 at the side edge portion of the second fastener stringer 120. The first and second zipper tapes 310 and 320 are sometimes referred to as left and right zip fastener tapes, or simply zipper tapes. The first and second fastener zippers 110 and 120 are sometimes referred to as left and right zippers, or simply zippers. The first and second fastener elements 210 and 220 are sometimes referred to as left and right fastener elements, or simply as fastener elements. The first and second core strings 115 and 125 are sometimes referred to as left and right core strings, or simply as core wires. The stop 500 of the illustrated example is a rear stop, but can also be used as a front stop. In the present specification, the front-rear direction is understood based on the moving direction of the slider 400. By the advancement of the slider 400, the left and right zipper tapes 310, 320 are closed. By the slider 400 retreating, the left and right zipper tapes 310, 320 are opened. The left and right direction is one of the directions orthogonal to the front and rear direction. The left and right direction is aligned with the lateral arrangement direction of the left and right zipper chains. The left-right direction is parallel to the upper surface of the chain fabric and the lower surface of the chain fabric of each of the fastener chain fabrics 110 and 120. The vertical direction is orthogonal to the front-rear direction and the left-right direction. The zipper chain fabric 110, 120 is a flexible material comprising a woven fabric, a knitted fabric, or a tissue other than the above, and has a chain upper surface 111, 121 and a lower surface of the chain fabric defining the thickness of the fastener chain fabric 110, 120. 112, 122. The fastener chain fabrics 110 and 120 have chain fabric main body portions 113 and 123 and side edge portions 114 and 124 provided with core wires 115 and 125. Each of the core strings 115 and 125 has a portion which is raised from the upper and lower surfaces 111 and 121 of the chain fabric main body portions 113 and 123 and the lower surface 112, 122 of the chain cloth. In some cases, the core strands 115, 125 comprise a plurality of twisted yarns. The zipper elements 210, 220 are the sprocket of the resin block in the illustrated example. In some cases, the fastener elements 210 and 220 are integrally formed on the side edges of the fastener chains 110 and 120 by injection molding of a resin. The fastener elements 210, 220 have a base portion 230 fixed to the core strings 115, 125 as exemplarily shown in Fig. 4, and a head portion 240 projecting from the base portion 230 toward the outside of the fastener stringer. Further, the outer side of the fastener chain means the direction or position of the point or position on the upper surface or the lower surface of the fastener fabric of the fastener chain fabric 110, 120 toward the outer surface or the lower surface of the fastener fabric. In some cases, the outer side of the zipper chain cloth from the upper or lower surface of the fastener fabric of the zipper chain fabric 110, 120 is traversed over the core ropes 115, 125, toward the point above or below the upper surface of the chain fabric or position. When the left and right fastener elements 210, 220 are engaged, the head 240 of the left fastener element 210 is disposed between the heads 240 of the right and left adjacent fastener elements 220. In some cases, a recess is provided on the top surface of the head 240. The base portion 230 is provided with a convex portion that can be fitted into the concave portion of the top surface of the head portion 240. The fastener elements 210 and 220 are not limited to the types illustrated in the drawings, and metal fastener elements, ring fastener elements, or the like may be employed. In a specific case, the zipper chain in a state in which the left and right fastener stringers 310 and 320 are closed is sufficiently flexible, so that the fastener element is thinned. As shown in Fig. 9, the left and right widths of the fastener elements 210 and 220 are set to L3, and the maximum thickness of the upper and lower sides of the fastener elements 210 and 220 is set to TH3 as shown in Fig. 11 . In some cases, TH3/L3 < 0.6 is satisfied. In some cases, TH3/L3 < 0.55 is satisfied. The left and right widths of the fastener elements 210, 220 may also be referred to as the length of the fastener elements. In some cases, (TH3m+TH3n)/TH3≧0.4 is satisfied. In some cases, (TH3m+TH3n)/TH3≧0.45 is satisfied. Further, as shown in Fig. 11, TH3m indicates the thickness between the upper surface of the fastener elements 210, 220 and the upper vertex of the core strings 115, 125. As shown in Fig. 11, TH3n represents the thickness between the lower surface of the fastener elements 210, 220 and the apex of the lower side of the core strings 115, 125. The entire contents of the zipper elements 210 and 220 are disclosed in the specification by reference. The slider 400 includes an upper wing 410, a lower wing 420 opposite to the upper wing 410, a connecting post 430 connecting the upper wing 410 and the lower wing 420, and a pull tab disposed on the upper surface of the upper wing 410. The post 440 and the tabs (not shown) are mounted. The upper wing 410 has an inward facing surface 412 opposite the lower wing plate 420 and an upper surface 411 opposite the inward facing surface. The lower wing panel 420 has an inward facing surface 422 opposite the upper wing panel 410 and a lower surface 421 opposite the inward facing surface 422. The connecting post 430 is a column portion extending in the vertical direction from the left and right centers of the slider 400, but extends in the front-rear direction as illustrated in FIG. The slider 400 has a pair of introduction ports on the left and right sides of the front end portion, that is, the connecting post 430, and has a meshing opening at the rear end portion thereof. The slider 400 is provided with a Y-shaped sprocket path in which the passage is branched by the connecting post 430. Further, a Y-shaped sprocket path is formed between the upper blade 410 and the lower blade 420. In the illustrated example, the left and right side edge portions of the upper blade 410 are provided with flange portions 460 that protrude downward. Similarly, a flange portion 460 that protrudes upward is provided on the left and right side edge portions of the lower blade 420. Thus, the Y-shaped sprocket passage is defined by the flange portions 460. This sprocket path can be better understood with reference to FIG. The slider 400 is a resin slider in some cases and a metal slider in other cases. As the slider 400 advances, the left and right fastener elements 210, 220 are engaged. The non-engaged left and right fastener elements 210, 220 enter the slider 400 through the introduction port of the slider 400, and are brought into engagement by the connecting post 430. Thereafter, the left and right fastener elements 210, 220 of the engaged state are separated from the engagement opening of the slider 400. As the slider 400 retreats, the left and right fastener elements 210, 220 become non-engaged. The left and right fastener elements 210, 220 of the engaged state enter the slider 400 via the engagement opening of the slider 400, and become non-engaged as they pass through the connecting post 430. Thereafter, the non-engaged fastener elements 210, 220 exit the slider 400 via the respective inlets of the slider 400. The stopper 500 is fixed to the first core cord 115 of the first fastener stringer 110 and the second core cord 125 of the second fastener stringer 120, and connects the first fastener chain fabric 110 and the second fastener chain fabric 120. In other words, the stopper 500 is fixed to the resin block of the core strands 115, 125 of the fastener stringers 110, 120, which prevents the slider 400 from being stopped in such a manner as to prevent the slider 400 from retreating. In some cases, the stopper 500 is formed by introducing the molten resin into the cavity of the mold and solidifying it by disposing the opposite side edges of the fastener chain fabrics 110 and 120 in the cavity of the mold. In some cases, the stop 500 and the zipper chain are formed by different steps. In some cases, the stop 500 and the zipper chain are formed by the same step. The stopper 500 has a body portion 510, an upper raised portion 540 disposed on the upper surface of the body portion 510, and a lower raised portion 550 disposed on the lower surface of the body portion 510.

The upper ridge portion 540 is provided on the upper surface 521 of the upper flat plate portion 520. The lower ridge 550 is provided on the lower surface 531 of the lower flat plate portion 530. In the illustrated example, the upper surface 521 and the lower surface 531 are substantially flat surfaces. However, in another example, the upper surface 521 and the lower surface 531 are non-flat surfaces, such as gentle sloped surfaces. The stopper 500 has a first end portion 501 on the first and second fastener elements 210 and 220 side, and a second end portion 502 on the opposite side of the first end portion 501. The first end portion 501 may be referred to as a front end portion, and the second end portion 502 may be referred to as a rear end portion. Upper and lower raised portions 540 and 550 are provided at the first end portion 501 of the stopper 500. The upper and lower raised portions 540 and 550 are not provided at the second end portion 502 of the stopper 500. As shown in Fig. 7, the first end portion 501 of the stopper 500 has a maximum thickness TH1 in the vertical direction, and the second end portion 502 has a maximum thickness TH2 in the vertical direction. The maximum thickness TH1 is greater than the maximum thickness TH2. The maximum thicknesses TH1 and TH2 are both greater than the maximum thickness TH3 of the upper and lower sides of the fastener elements 210, 220. As shown in FIG. 16, the maximum thicknesses TH1 and TH2 are smaller than the upper and lower intervals W41 of the upper surface 411 of the upper surface of the upper surface of the lower surface of the lower surface of the upper surface 411 of the lower surface of the lower surface of the lower surface of the lower surface of the lower surface of the lower surface of The maximum thickness TH1 and TH2 are both greater than the upper and lower spacing W42 of the inward facing surface 412 of the upper wing 410 of the slider 400 and the inward facing surface 422 of the lower wing 420. In some cases, 1.02 < TH1/TH2 < 1.5 is satisfied. As shown in FIG. 5, the stopper 500 has a first portion 500p sandwiching the first core string 115, a second portion 500q sandwiching the second core string 125, and a first portion 500p and a second portion 500q.

The lower flat plate portion 530 includes a left side portion 530p disposed under the fastener chain cloth 110, a right side portion 530q disposed under the fastener chain cloth 120, and an intermediate portion 530r connected thereto. The intermediate portion 520r of the upper flat plate portion 520 and the intermediate portion 530r of the lower flat plate portion 530 are vertically connected between the first core cord 115 and the second core cord 125. The upper surface of the main body portion 510, that is, the upper surface 521 of the upper flat plate portion 520, and the lower surface 531 of the lower flat plate portion 530, which is the lower surface of the main body portion 510, are provided with the upper portion and the lower raised portion 540, 550 which are mutually convex in opposite directions. . The upper and lower raised portions 540 and 550 are provided at the first end portion 501 of the stopper 500, and are swelled up and down in the opposite direction from the first end portion 501. The upper raised portion 540 is raised, extended, and protruded upward from the upper surface 521 of the upper flat plate portion 520. The lower raised portion 550 is raised, extended, and protruded downward from the lower surface 531 of the lower flat plate portion 530. As shown in FIG. 7, the upper ridge portion 540 and the lower ridge portion 550 are present in a plane PL10 that is orthogonal to each other in the front-rear direction. The upper raised portion 540 has a first top surface 544, first and second inclined surfaces 541 and 542, and an upper inclined surface 543. The lower raised portion 550 has a second top surface 554, third and fourth inclined surfaces 551 and 552, and a lower inclined surface 553. The first top surface 544 is disposed between the stop surface 560 and the upper inclined surface 543. The second top surface 554 is disposed between the stop surface 560 and the lower inclined surface 553. In the illustrated example, the first and second top surfaces 544 and 554 are flat surfaces that face each other in the up-and-down direction. The first and second inclined surfaces 541 and 542 are provided so as to sandwich the first top surface 544, and approach the upper flat plate portion 520 as they move away from the first top surface 544 toward the opposite side in the left-right direction. The first and second inclined faces 541 and 542 extend in a state of traversing the first and second core strings 115 and 125, respectively. The third and fourth inclined faces 551 and 552 are provided so as to sandwich the second top surface 554, and approach the lower flat plate portion 530 as they move away from the second top surface 554 toward the opposite side in the left-right direction. The third and fourth inclined faces 551 and 552 respectively extend across the first and second core strings 115 and 125. The first inclined surface 541 and the third inclined surface 551 extend in a wedge shape that is close to each other as extending to the left side. The second inclined surface 542 and the fourth inclined surface 552 extend in a wedge shape that extends toward the right side. The upper inclined surface 543 gradually approaches the upper surface 521 of the upper flat plate portion 520 as it extends rearward from the first top surface 544. The lower inclined surface 553 gradually approaches the lower surface 531 of the lower flat plate portion 530 as it extends rearward from the second top surface 554. The upper and lower inclined surfaces 543 and 553 extend in a wedge shape that is close to each other as extending rearward. As shown in FIG. 6(d), the upper inclined surface 543 and the upper surface 521 of the upper flat plate portion 520 intersect at a first angle θ1. The first angle θ1 is, for example, 10° to 80°. The lower inclined surface 553 also intersects the lower surface 531 of the lower flat plate portion 530 at the second angle θ2. In the example of the figure, θ1 = θ2. Both θ1 and θ2 are acute angles. When the first and second angles θ1 and θ2 are too large, the protrusions of the upper and lower ridges 540 and 550 are conspicuous. Therefore, in some embodiments, the first and second angles θ1 and θ2 are set to be 80° or less. When the first and second angles θ1 and θ2 are too small, it is difficult to ensure sufficient bulging of the upper and lower ridges 540 and 550. Therefore, in some embodiments, the first and second angles θ1 and θ2 are set to 10° or more. As shown in FIG. 6(b), the angle θ3 between the first inclined surface 541 and the first top surface 544 is 130° to 150°. The angle θ4 between the second inclined surface 542 and the first top surface 544 is 130° to 150°. Θ3 and θ4 are both obtuse angles. In the illustrated example, the angle formed by the third inclined surface 551 and the second top surface 554 is equal to θ3. In the illustrated example, the angle formed by the fourth inclined surface 552 and the second top surface 554 is equal to θ4. The upper surface of the stopper 500 includes a first top surface 544, a first inclined surface 541, a second inclined surface 542, an upper inclined surface 543, and an upper flat surface 520 upper surface 521. The lower surface of the stopper 500 includes a second top surface 554, a third inclined surface 551, a fourth inclined surface 552, and a lower inclined surface 553, and a lower surface 531 of the lower flat plate portion 530. The stopper 500 has a peripheral side which is connected to the outer circumference of the upper surface and the outer circumference of the lower surface. As shown in Fig. 6(a), the outer peripheral side surface of the stopper 500 includes the opposite surface 561 opposite to the stop surface 560 and the stop surface 560 which are disposed opposite to the first and second fastener elements 210 and 220. The left side surface 562 extending between the stop surface 560 and the opposite surface 561 and the right side surface 563 extending between the stop surface 560 and the opposite surface 561. An arcuate edge exists between the stop surface 560 and the first top surface 544 of the upper raised portion 540, between the stop surface 560 and the first inclined surface 541, and between the stop surface 560 and the second inclined surface 542. There is also an arcuate edge between the stop surface 560 and the second top surface 554 of the lower raised portion 550, between the stop surface 560 and the third inclined surface 551, and between the stop surface 560 and the fourth inclined surface 552. These arcuate edges help to make the stop 500 look small. The stop surface 560 includes a front surface of the upper flat plate portion 520, a front surface of the lower flat plate portion 530, a front surface of the upper raised portion 540, and a front surface of the lower raised portion 550. The front surface of the upper flat plate portion 520, the front surface of the lower flat plate portion 530, the front surface of the upper raised portion 540, and the front surface of the lower raised portion 550 are opposed to or facing the first and second fastener elements 210 and 220, respectively. The second zipper elements 210 and 220 are aligned on the side. As clearly shown in FIG. 6(d), the plane PL544 where the first top surface 544 of the upper raised portion 540 is located is located above the plane PL521 where the upper surface 521 of the upper flat plate portion 520 is located. It is considered that the stop surface 560 of the stopper 500 is extended upward corresponding to the upper ridge portion 540. Similarly, the plane PL 554 where the second top surface 554 of the lower ridge portion 550 is located is located below the plane PL 531 where the lower surface 531 of the lower flat plate portion 530 is located. It is considered that the stop surface 560 of the stopper 500 is extended downward in accordance with the lower raised portion 550. That is, the stop surface 560 has an upper and lower width W560 corresponding to the upper and lower ridges 540, 550. Furthermore, the upper raised portion 540 is not formed over the entire upper surface 521 of the upper flat plate portion 520. Similarly, the lower ridges 550 are not formed over the entire lower surface 531 of the lower flat plate portion 530. The increase in the upper and lower widths W560 of the stop faces 560 helps to increase the anchoring force of the stops 500 for the core strands 115, 125 of the zipper strips 110, 120, and ensures that the stops 500 are behind the wings 400 of the slider 400. More stable surface contact between the rear portion of the portion and the lower wing plate 420. In a comparative example, the upper and lower ridges 540, 550 are provided in such a manner that the upper and lower widths W560 of the stop surface 560 are not increased. For example, the upper and lower raised portions 540, 550 are disposed at the second end portion 502 of the stop 500. In this case, the upper and lower flat plate portions 520, 530 are in contact with the rear end portion of the upper surface of the wing 410 and the rear end portion of the lower wing plate 420 of the slider 400. In this case, it is difficult to ensure stable surface contact. The upper and lower width W560 of the stop surface 560 coincides with the upper and lower surfaces of the first top surface 544 of the upper raised portion 540 and the second top surface 554 of the lower raised portion 550. The upper width W561 of the opposite surface 561 on the opposite side of the stop surface 560 is spaced from the upper surface 521 of the upper flat plate portion 520 and the lower surface 531 of the lower flat plate portion 530. The relationship between W560 and W561 is completely adapted to the relationship between TH1 and TH2 described above. As shown in FIG. 9, the stopper 500 has a right and left width W500 that coincides with the total left and right widths W200 of the left and right fastener elements 210 and 220 in the engaged state. In the illustrated example, the braking force for stopping the stop 500 of the slider 400 is ensured by the sufficient upper and lower width W560 of the stop surface 560 of the stop 500, but is not necessarily limited thereto. Further, the total left and right widths W200 of the left and right fastener elements 210 and 220 in the meshing state coincide with the right and left intervals of the side faces of the base 230 facing the inside of the fastener chain, respectively, of the left and right fastener elements 210 and 220. As shown in FIG. 17, the stopper 500 has a left-right width W500 that can enter the slider 400, similarly to the meshing fastener elements 210 and 220. Furthermore, in practice, the stop 500 cannot enter the slider 400 due to the stop surface 560 having a large upper and lower width W560. The right and left width W500 of the stopper 500 does not reach the left-right interval W460 of the opposing inner faces of the left and right flange portions 460 of the rear end portions of the slider 400. In a specific case, the upper and lower width W560 of the stop surface 560 is 3.0 mm to 4.8 mm. The maximum thickness TH1 of the first end portion 501 is 3.0 mm to 4.8 mm. The maximum thickness TH2 of the second end portion 502 is 2.3 mm to 3.7 mm. The left and right width W500 of the stop 500 is 5.6 mm to 6.2 mm. The left and right widths L3 of the zipper elements are 3.0 mm to 5.0 mm. The maximum thickness TH3 of the fastener elements 210, 220 is 1.8 mm to 2.2 mm. The full flexibility of the zipper chain is also ensured. The stopper 500 contains a resin such as polyacetal. The fastener elements 210 and 220 include a resin such as a reinforced polyacetal. The resin of the stop 500 exhibits a weaker fixing force than the resin of the fastener elements 210, 220 with respect to the fastener chain. The upper raised portion 540 has a sloped surface 543 that gradually approaches the upper flat plate portion 520 as it extends toward the second end portion 502 side. The upper inclined surface 543 extends until reaching the upper surface 521 of the upper flat plate portion 520 where the upper raised portion 540 is provided. Further, the lower raised portion 550 has a sloped surface 553 that gradually approaches the lower portion of the lower flat plate portion 530 as it extends toward the second end portion 502 side. The lower ridge 550 extends until reaching the lower surface 531 of the flat plate portion 530 provided with the lower ridge 550. It is possible to ensure a sufficient upper and lower width W560 of the stop surface 560, and to moderate the degree of protrusion of the upper and lower ridges 540, 550. In another expression, the upper inclined surface 543 of the upper raised portion 540 is a curved surface that gradually faces upward as it extends forward. When the pull piece of the slider 400 is grasped by hand, the upper inclined surface 543 of the upper raised portion 540 does not interfere with the movement of the finger, and sometimes functions to guide the movement of the hand. Thereby, the operability of the zipper 600 is improved. When the pull tab is also provided on the side of the flap 420 on the lower side of the slider 400, the lower inclined portion 550 of the lower raised portion 550 functions similarly. The first and second inclined faces 541 and 542 of the upper raised portion 540 extend in opposite directions across the core strings 115 and 125. The first inclined surface 541 extends to the left side from the first top surface 544 of the upper raised portion 540 across the first core rope 115, and approaches the upper flat plate portion 520 while extending to the left side. Similarly, the second inclined surface 542 of the upper raised portion 540 extends to the right from the first top surface 544 of the upper raised portion 540 across the second core cord 125, and approaches the upper flat plate while extending to the right side. Part 520. Not only the width W560 of the lower surface 560 but also the upper and lower ridges 540 and 550 can be relaxed. In another expression, the first inclined surface 541 is an inclined surface that gradually faces upward as it extends toward the left and right center sides. The second inclined surface 542 is an inclined surface that gradually faces upward as it extends toward the left and right center sides. When the pull piece of the slider 400 is gripped by the hand, the first inclined surface 541 and the second inclined surface 542 of the upper raised portion 540 do not interfere with the movement of the finger, and may instead function to guide the movement of the hand. . When the slider is also provided on the side of the flap 420 on the lower side of the slider 400, the third inclined surface 551 and the fourth inclined surface 552 of the lower raised portion 550 function similarly. A projection 590 that protrudes toward the first fastener element 210 side is provided on the stop surface 560 of the stopper 500. The protrusion 590 is fixed to the first core rope 115 and has a size that can be inserted into the slider 400. The protrusion 590 has a curved surface 599 for avoiding interference with the second fastener element 220 adjacent to the stop 500. As shown in FIG. 11, the protrusion 590 includes an upper portion 592 disposed on the first fastener stringer 110 and a lower portion 593 disposed on the first fastener stringer 110, and the first core string 115 is sandwiched therebetween. Between. As illustrated in FIG. 16, when the slider 400 is in contact with the stop surface 560 of the stop 500, between the first top surface 544 of the upper ridge 540 and the upper surface 411 of the upper surface 410 of the slider 400. A step 710 is produced. Further, a step 720 is generated between the second top surface 554 of the lower raised portion 550 and the lower surface 421 of the lower blade 420. The upper and lower widths W560 of the stop faces 560 of the stop 500 are smaller than the upper and lower intervals W41 of the upper surface 411 of the upper wing 410 of the slider 400 and the lower surface 421 of the lower wing 420. The upper and lower widths W560 of the stop faces 560 of the stop 500 are greater than the upper and lower faces W42 of the inward facing faces 412 of the upper wings 410 of the slider 400 and the inward faces 422 of the lower wings 420. It is ensured that the stop 500 is relatively small in relation to the slider 400. In a specific case, it is desirable that the zipper chain in a state in which the left and right zipper tapes 310, 320 are closed has high flexibility. In this case, attention is paid to reducing the thickness of the fastener elements 210 and 220, and similarly, the stopper 500 is made thinner. In providing a thinner resin stopper, a stop that does not come into contact with the upper or lower flaps 410, 420 of the slider 400 and contact the flange portion 460 of the slider 400 is studied. However, according to the study by the inventors of the present invention, it is clear that in this case, sufficient restraining force for stopping the stopper 500 of the slider 400 cannot be ensured. In view of this, the inventor of the present invention has selected a method which is generally not preferred, that is, to increase the thickness of the stopper 500. Such a stop 500 promotes the deterioration of the flexibility of the zipper chain. However, compared to the zipper teeth, the range of the stop 500 in the zipper chain is extremely small. Therefore, the benefit of increasing the thickness of the stop 500 greatly exceeds the disadvantage of the flexibility degradation of the zipper chain. In the present embodiment, the upper ridge portion 540 and the lower ridge portion 550 are provided in such a manner that the upper and lower widths W560 of the stop surface 560 of the stopper 500 are increased. The upper raised portion 540 and the lower raised portion 550 are raised in the opposite directions from the upper surface 521 of the upper flat plate portion 520 and the lower surface 531 of the lower flat plate portion 530. In the case where the thickness of the stop 500 is increased in this manner, the stop 500 can be more firmly fixed to the core ropes 115, 125, thereby ensuring that the stop 500 is attached to the upper and lower wings 410 of the slider 400. Full face contact of the flaps 420. By the upper ridge portion 540 and the lower ridge portion 550, an increase in the partial thickness of the stopper 500 is achieved, and the increase in the partial thickness increases the upper and lower width W560 of the stop surface 560. In the non-limiting exemplary embodiment, the upper inclined surface 540 is provided with an upper inclined surface 543, and the lower raised portion 550 is provided with a lower inclined surface 553. In addition to the benefits described above, it is also possible to suppress a significant increase in the thickness of the stop 500. In addition to the benefits described above, the first and second inclined faces of the upper raised portion 540 and the first and second inclined faces of the lower raised portion 550 also contribute to suppressing a significant increase in the thickness of the stop 500. According to the above teachings, various modifications can be made to the respective embodiments. The symbols attached to the scope of the patent application are for reference and should not be used as a limitation for the purpose of limiting the scope of the patent application.
