Formed in the face. Further, the upper surface 21a, 21b of the base portion 21 is formed by an inclined surface whose width gradually widens from the neck portion 23 toward the outer end portion 21c of the base portion 21. Further, the upper surface 21a, 21b of the base portion 21 is formed by a curved surface whose width gradually widens from the outer end portion 21c toward the neck portion 23, that is, when the upper and lower surfaces 21a, 21b are viewed in the back side direction, Curved surface with an arc shape.
又，如圖4~圖6所示，於鏈布側緣部13，沿著鏈布構件12之表背方向分別織入或編入有2根芯線13a。藉此，如圖9所示，即便將鏈布構件12拉伸至滑件30之寬度方向外側，亦以表背方向中心線DL為交界，於鏈布構件12之表背方向兩側各固定有1根芯線13a，因此，各芯線13a僅受到來自單向之力。亦即，表側之芯線13a實質上僅受到來自上突緣33a之力，而背側之芯線13a實質上僅受到來自下突緣33b之力，因此，芯線13a不會極端地被擠壓(參照圖9之一點鏈線)。Further, as shown in FIGS. 4 to 6, two core wires 13a are woven or knitted into the chain side edge portion 13 along the front and back directions of the chain member 12. As a result, as shown in FIG. 9, even if the chain member 12 is stretched to the outer side in the width direction of the slider 30, the center line DL of the front and back directions is used as a boundary, and is fixed to both sides of the chain member 12 in the front and back directions. There is one core wire 13a, and therefore, each core wire 13a receives only a force from one direction. That is, the front side core wire 13a is substantially only subjected to the force from the upper flange 33a, and the back side core wire 13a is substantially only subjected to the force from the lower flange 33b, and therefore, the core wire 13a is not extremely squeezed (refer to Figure 9 is a point chain).
進而，如圖8及圖9所示，上下突緣33a、33b間之間隙S3之上下方向尺寸L4係設定為小於將上述鏈布構件12拉伸至寬度方向外側時(橫向拉力)之2根芯線13a之表背方向尺寸L5。藉此，2根芯線13a不會自上下突緣33a、33b間之間隙 S3脫出至外側，因此，2根芯線13a不會夾在該間隙S3。Further, as shown in FIGS. 8 and 9, the upper and lower dimension L4 of the gap S3 between the upper and lower flanges 33a and 33b is set to be smaller than two when the chain member 12 is stretched to the outer side in the width direction (lateral tension). The front and back direction dimension L5 of the core wire 13a. Thereby, the two core wires 13a are not separated from the gap between the upper and lower flanges 33a, 33b. Since S3 is taken out to the outside, the two core wires 13a are not caught in the gap S3.
再者，將上述鏈布構件12拉伸至寬度方向外側時之2根芯線13a之表背方向尺寸L5係可藉由圖10所示之測定器40來測定。該測定器40係包括下模具41，其係於上表面形成有收容鏈布構件12之2根芯線13a(鏈布側緣部13)之大致V字狀之芯線收容槽41a；以及上模具42，其以相對下模具41下降之方式設置，且於下表面形成有將收容於芯線收容槽41a中之2根芯線13a擠壓之大致倒V字狀之芯線擠壓槽42a。又，芯線收容槽41a及芯線擠壓槽42a之角度係設定為90°。又，於下模具41，與芯線收容槽41a之底部連續地形成有收容鏈布構件12之鏈布收容部41b。而且，測定器40之測定係藉由利用上模具42朝著下模具41擠壓2根芯線13a而進行，且可測定上模具42受到特定壓力時之芯線收容槽41a與芯線擠壓槽42a之交點P1、P2間之壓縮尺寸(PM(Pressure Measurement，壓力測量)值)D。In addition, the front and back direction dimension L5 of the two core wires 13a when the chain fabric member 12 is stretched to the outer side in the width direction can be measured by the measuring device 40 shown in FIG. The measuring device 40 includes a lower mold 41 which is formed with a substantially V-shaped core wire receiving groove 41a for accommodating two core wires 13a (chain side edge portions 13) of the chain member 12, and an upper mold 42. The lower mold 41 is disposed to be lowered, and a substantially inverted V-shaped core wire pressing groove 42a for pressing the two core wires 13a accommodated in the core wire receiving groove 41a is formed on the lower surface. Moreover, the angle of the core wire receiving groove 41a and the core wire pressing groove 42a is set to 90 degrees. Further, in the lower mold 41, a chain accommodating portion 41b for accommodating the chain member 12 is formed continuously with the bottom portion of the core wire accommodating groove 41a. Further, the measurement by the measuring device 40 is performed by pressing the two core wires 13a toward the lower die 41 by the upper die 42, and the core wire receiving groove 41a and the core wire pressing groove 42a when the upper die 42 is subjected to a specific pressure can be measured. The compression size (PM (Pressure Measurement) value) D between the intersection points P1 and P2.
此處，上述2根芯線13a所受之壓力係設想相當於表背方向尺寸L5，並將本發明之鏈布構件12安裝於衣服或提包等被著體進行使用之情形時鏈布構件12所受之橫向拉力，且設為5kgf。亦即，本發明，係藉由將上下突緣33a、33b間之間隙S3之上下方向尺寸L4設定為小於以5kgf之壓力被擠壓時之芯線13a之表背方向尺寸L5，而即便於將鏈布構件12安裝於被著體進行使用之情形時，亦可防止由於橫向拉力而使芯線13a夾在上下突緣33a、33b間之間隙S3中。Here, the pressure applied to the two core wires 13a is assumed to correspond to the front and back direction dimension L5, and when the chain fabric member 12 of the present invention is attached to a garment such as a clothes or a bag, the chain member 12 is used. It is subjected to lateral tension and is set to 5kgf. That is, the present invention is to set the upper and lower direction dimension L4 of the gap S3 between the upper and lower flanges 33a and 33b to be smaller than the front and back direction dimension L5 of the core wire 13a when pressed at a pressure of 5 kgf, even if When the chain fabric member 12 is attached to the object to be used, it is also possible to prevent the core wire 13a from being caught in the gap S3 between the upper and lower flanges 33a, 33b due to the lateral pulling force.
又，如圖2所示，於上下突緣33a、33b之前端部，分別 形成有與鏈布構件12之長度方向平行地延伸之平行部39，且該平行部39係比導引柱34之前後方向長度之1/2更向前方延伸。藉由該平行部39，而於嚙合位置之某種程度近前處調整進入滑件30之導入口36之鏈齒15之姿勢，從而防止鏈布構件12之扭曲變形等變形，因此，芯線13a難以卡在上下突緣33a、33b間之間隙S3。Moreover, as shown in FIG. 2, at the front ends of the upper and lower flanges 33a and 33b, respectively A parallel portion 39 extending in parallel with the longitudinal direction of the chain member 12 is formed, and the parallel portion 39 extends forward more than 1/2 of the length of the guide post 34 in the front-rear direction. By the parallel portion 39, the posture of the element 15 entering the introduction port 36 of the slider 30 is adjusted to a certain extent in the vicinity of the meshing position, thereby preventing deformation of the chain member 12 such as distortion or the like, and therefore, the core wire 13a is difficult. It is caught in the gap S3 between the upper and lower flanges 33a, 33b.
又，如圖3及圖6所示，鏈齒15之設計部16及嚙合部17之後端部(外端部21c側之端部)係形成於較芯線13a為鏈布構件12側(亦即，與固定有芯線13a之側緣為相反側之側緣側)。藉此，一面嚙合部17之後端部與上下突緣33a、33b接觸，一面鏈齒15於滑件30內移動，因此，芯線13a難以與滑件30之上下突緣33a、33b接觸，從而防止芯線13a受損。又，由於形成於較芯線13a為鏈布構件12側的嚙合部17之後端部係彎曲之形狀，故而可順利地導引至滑件30內。Further, as shown in FIGS. 3 and 6, the design portion 16 of the fastener element 15 and the rear end portion (the end portion on the outer end portion 21c side) of the meshing portion 17 are formed on the side of the chain member 12 on the core wire 13a (that is, The side edge side opposite to the side edge to which the core wire 13a is fixed is attached). Thereby, the end portion of the engaging portion 17 is in contact with the upper and lower flanges 33a, 33b, and the sprocket 15 is moved inside the slider 30. Therefore, the core wire 13a is hard to come into contact with the upper and lower flanges 33a, 33b of the slider 30, thereby preventing The core wire 13a is damaged. Moreover, since the end portion is formed in a shape in which the end portion of the mesh portion 17a on the side of the chain member 12 is curved, it can be smoothly guided into the slider 30.
如此構成之拉鏈10，係設計部16於表側方向觀察時，以設計部16之左右方向中心線HL為基準形成為上下對稱且以上下方向中心線VL為基準形成為左右對稱之大致橢圓形狀，因此，可確保拉鏈10之柔軟性，並且提高拉鏈10之設計性。又，即便於插穿於滑件30之鏈齒導引路38時，亦不會被導入口36側之開口部卡住，因此，亦可確保滑件30之滑動性。The zipper 10 is configured such that the design portion 16 is formed in a vertically elliptical shape with respect to the center line HL in the left-right direction of the design portion 16 and is formed in a substantially elliptical shape in which the left and right symmetry is defined on the basis of the center line VL in the vertical direction. Therefore, the flexibility of the zipper 10 can be ensured, and the design of the zipper 10 can be improved. Moreover, even when inserted into the element guide path 38 of the slider 30, the opening of the inlet port 36 side is not caught, so that the slidability of the slider 30 can be ensured.
又，設計部16係於上下方向觀察及自左右方向觀察時，形成為整體呈彎曲形狀之大致半球形狀，故而如圖11所 示，即便使拉鏈10向背側彎曲成凸起狀態，相鄰之設計部16亦不會立即彼此干涉，因此，可提高拉鏈10之柔軟性。又，於彼此相鄰之鏈齒15之間設置有間隙S1，故而可進一步提高拉鏈10之柔軟性。Further, the design portion 16 is formed in a substantially hemispherical shape having a curved shape as a whole when viewed in the up-and-down direction and when viewed from the left-right direction, and thus is as shown in FIG. It is shown that even if the zipper 10 is bent to the back side in a convex state, the adjacent design portions 16 do not immediately interfere with each other, so that the flexibility of the zipper 10 can be improved. Further, since the gap S1 is provided between the sprocket teeth 15 adjacent to each other, the flexibility of the zipper 10 can be further improved.
又，即便使拉鏈10向背側彎曲成凸起狀態，亦由於延伸至較鏈布構件12之表背方向中心線DL更為設計部16側而形成之第1卡合部24相互卡合，而一面維持左右一對鏈齒排14之卡合，一面提高拉鏈10之柔軟性。又，即便相較於圖11中所示之位置，向背側彎曲成凸起狀態，此後相鄰之設計部16之上下彎曲面亦會抵接，防止更大程度之彎折。由於如此般，自設計部16之表面形成於上下表面之間之彎曲面彼此抵接，因此，即便彎曲一定程度以上，亦可一面維持鏈齒排14之卡合，一面確保拉鏈10之柔軟性。Further, even if the zipper 10 is bent to the back side in a convex state, the first engaging portions 24 formed to extend toward the front side direction line DL of the chain member 12 and the design portion 16 side are engaged with each other. While maintaining the engagement of the pair of left and right chain rows 14, the flexibility of the zipper 10 is improved. Further, even if compared with the position shown in Fig. 11, the back side is bent into a convex state, and thereafter the upper and lower curved surfaces of the adjacent design portions 16 are abutted to prevent a greater degree of bending. Since the curved surfaces formed between the upper and lower surfaces from the surface of the design portion 16 are in contact with each other, the flexibility of the zipper 10 can be ensured while maintaining the engagement of the element rows 14 even when the bending is performed to a certain extent or more. .
又，如圖12所示，若使拉鏈10向表側彎曲成凸起之狀態，則因設置有間隙S2，而可確保拉鏈10之柔軟性，又，原本在直線狀嚙合之狀態下無助於卡合之第2卡合部25相互卡合，而使卡合部26之卡合面積變大，因此，左右一對鏈齒排14之卡合變得牢固。Further, as shown in Fig. 12, when the zipper 10 is bent to the front side in a state of being convex, the gap S2 is provided to ensure the flexibility of the zipper 10, and it is not helpful in the state of linear engagement. Since the engaged second engagement portions 25 are engaged with each other and the engagement area of the engagement portions 26 is increased, the engagement of the pair of left and right fastener element rows 14 is firm.
又，由於嚙合頭部22之上下表面22a、22b係藉由寬度自頸部23朝向嚙合頭部22之左右方向之外端部22c逐漸變窄之傾斜面而形成，且於第1卡合部24之上下端與相鄰之鏈齒15之第2卡合部25之豎立部之間形成有間隙S2，因此，如圖13所示，即便使拉鏈10向左右方向彎曲，相鄰之嚙合部17亦不會立即相互干涉，因此，可提高拉鏈10之柔軟 性。Further, since the upper surface 22a, 22b of the engaging head portion 22 is formed by an inclined surface whose width is gradually narrowed from the neck portion 23 toward the outer end portion 22c of the engaging head portion 22, and is in the first engaging portion. A gap S2 is formed between the lower end of the upper end of 24 and the upright portion of the second engaging portion 25 of the adjacent element 15 . Therefore, as shown in FIG. 13 , even if the zipper 10 is bent in the left-right direction, the adjacent engaging portion 17 will not interfere with each other immediately, therefore, the softness of the zipper 10 can be improved. Sex.
如上所說明，根據本實施形態之拉鏈10，由於上下突緣33a、33b間之間隙S3之上下方向尺寸L4小於以5kgf之壓力被擠壓時之2根芯線13a之表背方向尺寸L5，故而，芯線13a不會自上下突緣33a、33b間之間隙S3脫出至外側，從而可防止芯線13a夾在該間隙S3中。As described above, according to the zipper 10 of the present embodiment, since the upper and lower direction dimension L4 of the gap S3 between the upper and lower flanges 33a and 33b is smaller than the front and back direction dimension L5 of the two core wires 13a when pressed at a pressure of 5 kgf, The core wire 13a does not come out to the outside from the gap S3 between the upper and lower flanges 33a, 33b, so that the core wire 13a can be prevented from being caught in the gap S3.
又，根據本實施形態之拉鏈10，即便使用複數個鏈齒15間之間隔C2為鏈齒15之設計部16之上下方向之長度L3以上、且鏈齒15於嚙合時於鏈布構件12之上下方向上獨立配置之拉鏈，芯線13a亦不會自上下突緣33a、33b間之間隙S3脫出至外側，從而可防止芯線13a夾在該間隙S3。Further, according to the slide fastener 10 of the present embodiment, even when the interval C2 between the plurality of fastener elements 15 is the length L3 of the upper and lower directions of the design portion 16 of the fastener element 15, the fastener element 15 is engaged with the fastener member 12 at the time of meshing. The zipper that is independently disposed in the up-and-down direction does not escape from the gap S3 between the upper and lower flanges 33a, 33b to the outside, thereby preventing the core wire 13a from being caught in the gap S3.
又，根據本實施形態之拉鏈10，由於芯線13a係以於鏈布構件12之表背方向兩側各配置1根之狀態固定，因此，即便芯線13a受到較強之橫向拉力，亦可防止芯線13a極端變形。藉此，芯線13a不會自上下突緣33a、33b間之間隙S3脫出至外側，從而可防止芯線13a夾在該間隙S3中。Further, according to the zipper 10 of the present embodiment, since the core wire 13a is fixed in a state in which one of the two sides of the chain member 12 is disposed in the front and back directions, the core wire 13a can be prevented from being subjected to a strong lateral pulling force. 13a extreme deformation. Thereby, the core wire 13a does not come out to the outside from the gap S3 between the upper and lower flanges 33a, 33b, so that the core wire 13a can be prevented from being caught in the gap S3.
又，根據本實施形態之拉鏈10，上下突緣33a、33b係於其前端部包含與鏈布構件12之長度方向平行地形成之平行部39，且平行部39係比導引柱34之前後方向長度之1/2更向前方延伸，故可藉由該平行部39，而於嚙合位置之某種程度近前處調整進入滑件30之導入口36之鏈齒15之姿勢，從而可防止鏈布構件12之扭曲變形等變形。藉此，可使芯線13a難以卡在上下突緣33a、33b間之間隙S3中。Further, according to the slide fastener 10 of the present embodiment, the upper and lower flanges 33a and 33b are formed at the distal end portion thereof including the parallel portion 39 formed in parallel with the longitudinal direction of the chain member 12, and the parallel portion 39 is longer than the guide post 34. 1/2 of the length of the direction extends further forward, so that the parallel portion 39 can adjust the posture of the element 15 entering the introduction port 36 of the slider 30 at a certain position near the meshing position, thereby preventing the chain. The cloth member 12 is deformed by distortion or the like. Thereby, the core wire 13a can be hardly caught in the gap S3 between the upper and lower flanges 33a and 33b.
又，根據本實施形態之拉鏈10，由於鏈齒15之後端部係 形成於較芯線13a為鏈布構件12側，故而滑件30之上下突緣33a、33b難以接觸到芯線13a，因此可防止芯線13a受損。Further, according to the slide fastener 10 of the present embodiment, the end portion of the fastener element 15 is The core wire 13a is formed on the side of the chain member 12, so that the upper and lower flanges 33a, 33b of the slider 30 are difficult to contact the core wire 13a, so that the core wire 13a can be prevented from being damaged.
又，鏈齒15係於嚙合時於鏈布構件12之上下方向上獨立配置，且鏈齒15包含配置於鏈布構件12之表側之設計部16、及配置於鏈布構件12之背側且與相鄰之鏈齒15嚙合之嚙合部17，且該設計部16係於嚙合時與相鄰之設計部16分開配置，且具有整體呈彎曲形狀之大致半球形狀，故而可確保嚙合時之拉鏈10之柔軟性，並且可提高拉鏈10之設計性。Further, the sprocket 15 is independently disposed above and below the chain member 12 at the time of meshing, and the sprocket 15 includes a design portion 16 disposed on the front side of the chain member 12 and disposed on the back side of the chain member 12 and The engaging portion 17 that meshes with the adjacent sprocket 15 and the design portion 16 is disposed separately from the adjacent design portion 16 when engaged, and has a substantially hemispherical shape having a curved shape as a whole, thereby ensuring a zipper when meshing 10 is soft and can improve the design of the zipper 10.
又，根據本實施形態之拉鏈10，設計部16係以設計部16之左右方向中心線HL為基準形成為上下對稱，且以上下方向中心線VL為基準形成為左右對稱之大致橢圓形狀，故而設計部16成為平衡之形狀，從而可進一步提高設計部16之設計性。Further, according to the slide fastener 10 of the present embodiment, the design portion 16 is formed to be vertically symmetrical with respect to the center line HL of the design portion 16 in the left-right direction, and is formed in a substantially elliptical shape in which the center line VL in the vertical direction is symmetrical with respect to the left and right directions. The design portion 16 has a balanced shape, so that the design of the design portion 16 can be further improved.
又，根據本實施形態之拉鏈10，設計部16係於上下方向觀察及左右方向觀察時，形成為整體呈彎曲形狀之大致半球形狀，因此，即便使拉鏈10向背側彎曲成凸起狀態，相鄰之設計部16亦不會彼此干涉，故可提高拉鏈10之柔軟性。又，由於在彼此相鄰之鏈齒15之間設置有間隙S1，故而可進一步提高拉鏈10之柔軟性。Further, according to the slide fastener 10 of the present embodiment, the design portion 16 is formed in a substantially hemispherical shape having a curved shape as a whole when viewed in the vertical direction and in the left-right direction. Therefore, even if the slide fastener 10 is bent toward the back side, the phase is formed. The adjacent design portions 16 do not interfere with each other, so that the flexibility of the zipper 10 can be improved. Further, since the gap S1 is provided between the sprocket teeth 15 adjacent to each other, the flexibility of the zipper 10 can be further improved.
又，根據本實施形態之拉鏈10，由於第1卡合部24延伸至較鏈布構件12之表背方向中心線DL更為設計部16側而形成，故而即便使拉鏈10向背側彎曲成凸起之狀態，第1 卡合部24彼此之卡合亦不會解除，因此，可一方面維持左右一對鏈齒排14之卡合，且提高拉鏈10之柔軟性。Further, according to the slide fastener 10 of the present embodiment, since the first engaging portion 24 is formed to extend from the front-back direction center line DL of the chain member 12 to the design portion 16 side, the zipper 10 is bent toward the back side to be convex. State, first Since the engagement portions 24 are not engaged with each other, the engagement of the pair of left and right fastener element rows 14 can be maintained, and the flexibility of the slide fastener 10 can be improved.
又，根據本實施形態之拉鏈10，由於第2卡合部25自鏈布構件12之表背方向中心線DL之附近形成至嚙合部17之背側端部，且於第1卡合部24之上下端與相鄰之鏈齒15之第2卡合部25之豎立部之間形成有間隙S2，故而，於使拉鏈10向表側彎曲成凸起之狀態之情形時，原本在直線狀嚙合之狀態下無助於卡合之第2卡合部25會相互卡合，而使卡合部26之卡合面積變大，因此，可一方面使左右一對鏈齒排14之卡合變得牢固，且提高柔軟性。Further, according to the slide fastener 10 of the present embodiment, the second engagement portion 25 is formed from the vicinity of the front-back direction center line DL of the chain member 12 to the rear end portion of the engagement portion 17, and is in the first engagement portion 24 A gap S2 is formed between the upper lower end and the upright portion of the second engaging portion 25 of the adjacent fastener element 15, so that the linear fastener is originally engaged in the case where the zipper 10 is bent to the front side in a state of being convex. In this state, the second engaging portions 25 that do not contribute to the engagement are engaged with each other, and the engaging area of the engaging portions 26 is increased. Therefore, the engagement of the pair of left and right fastener elements 14 can be changed. It is firm and soft.
又，根據本實施形態之拉鏈10，嚙合頭部22之上下表面22a、22b係藉由自頸部23朝向嚙合頭部22之左右方向之外端部22c逐漸變窄之傾斜面而形成，且於第1卡合部24之上下端與相鄰之鏈齒15之第2卡合部25之豎立部之間形成有間隙S2，故而，即便使拉鏈10向左右方向彎曲，相鄰之嚙合部17亦不會彼此干涉，故可提高拉鏈10之柔軟性。Further, according to the slide fastener 10 of the present embodiment, the upper and lower surfaces 22a and 22b of the engaging head portion 22 are formed by the inclined surface which is gradually narrowed from the neck portion 23 toward the outer end portion 22c of the engaging head portion 22 in the left-right direction, and A gap S2 is formed between the lower end of the first engaging portion 24 and the standing portion of the second engaging portion 25 of the adjacent fastener element 15, so that the adjacent engaging portion is bent even in the left-right direction. 17 does not interfere with each other, so the flexibility of the zipper 10 can be improved.
又，根據本實施形態之拉鏈10，由於鏈齒15之設計部16之左右兩側面16c、16c及嚙合部17之左右兩側面21c、22c係由半圓狀之彎曲面形成，故而，鏈齒15容易進入滑件30之鏈齒導引路38。藉此，可以較少之力操作滑件30，故可容易地進行拉鏈10之開合。Further, according to the slide fastener 10 of the present embodiment, the left and right side faces 16c and 16c of the design portion 16 of the fastener element 15 and the left and right side faces 21c and 22c of the meshing portion 17 are formed by a semicircular curved surface, so that the fastener element 15 is formed. It is easy to enter the element guide path 38 of the slider 30. Thereby, the slider 30 can be operated with less force, so that the opening and closing of the zipper 10 can be easily performed.
再者，本發明並不限定於上述實施形態，可於本發明之技術思想範圍內進行各種變更。Further, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the technical idea of the present invention.
例如，上述實施形態，係為了確保拉鏈10之柔軟性，而 使設計部16中之至少自鏈布接觸面朝向設計部16之表側頂點(設計部16之左右方向中心線HL與上下方向中心線VL之交點)之彎曲面至少自鏈布接觸面側形成即可，而如圖14之變形例所示，亦可於鏈齒15之設計部16中形成與鏈布構件12平行之平坦部28。藉此，可對鏈齒15賦予與上述實施形態不同之設計。For example, in the above embodiment, in order to ensure the flexibility of the zipper 10, At least the curved surface of the design portion 16 facing the contact surface of the design portion 16 toward the front apex of the design portion 16 (the intersection between the center line HL of the left and right direction of the design portion 16 and the center line VL of the vertical direction) is formed at least from the side of the link contact surface. Alternatively, as shown in the modification of FIG. 14, the flat portion 28 parallel to the chain member 12 may be formed in the design portion 16 of the fastener element 15. Thereby, the sprocket 15 can be given a design different from the above embodiment.
又，本實施形態，係第1卡合部24之上下方向之長度L1亦可於左右一對鏈齒排14以直線狀相互嚙合之狀態下，設定為與彼此相鄰之設計部16間之間隙S1之上下方向之長度L2相同之長度。藉此，可略微犧牲柔軟性而提高卡合強度。Further, in the present embodiment, the length L1 of the first engaging portion 24 in the vertical direction may be set to be adjacent to the design portions 16 adjacent to each other in a state in which the pair of left and right element rows 14 are linearly meshed with each other. The length L2 of the upper and lower directions of the gap S1 is the same length. Thereby, the flexibility can be slightly sacrificed to increase the engagement strength.
