[發明所欲解決之問題] 鏈齒係與對向之鏈齒嚙合者，因此，使相對於鏈布之長度方向之固定位置於一方之鏈布及另一方之鏈布錯開。因此，即便為固定於各鏈布之複數個鏈齒中最靠近止擋之鏈齒，亦為固定於一方之鏈布之鏈齒第1靠近止擋，固定於另一方之鏈布之鏈齒第2靠近止擋。又，止擋為於一對鏈布之對向之方向上延長之形狀，因此，第2靠近之鏈齒與止擋之間隙遠大於第1靠近之鏈齒與止擋之間隙，對止擋附近之外觀造成不良影響。又，止擋係將一對鏈布接合者，因此，較理想為止擋相對於鏈布之安裝強度較高。本發明係考慮到上述實際情況而完成者，其目的在於使接合一對拉鏈鏈帶之止擋之安裝強度提昇，及使該止擋附近之外觀提昇。 [解決問題之技術手段] 本發明之拉鏈具備：一對拉鏈鏈帶；及止擋，其於一對拉鏈鏈帶之長度方向之一端部將兩者接合。一對拉鏈鏈帶具備：一對鏈布；及複數個鏈齒，其等沿一對鏈布之對向之各自的側緣部固定。鏈齒具備第1鏈齒部及第2鏈齒部，該第1鏈齒部位於鏈布之厚度方向之一方，並且無法與對向之鏈齒嚙合，該第2鏈齒部位於鏈布之厚度方向之另一方，並且與對向之鏈齒嚙合。第2鏈齒部具備：第2基部，其固定於鏈布；及嚙合部，其自第2基部朝向對向之鏈布突出，並且與對向之鏈齒嚙合。第1鏈齒部具備：第1基部，其固定於鏈布；及第1突出部，其自第1基部朝向對向之鏈布突出，並且其一部分相對於對向之鏈齒之嚙合部於鏈布之厚度方向上重疊。止擋具備止擋本體及止擋片，該止擋本體將一對鏈布接合並且於一對鏈布之對向之方向上延長，該止擋片相對於第2靠近止擋本體之鏈齒自止擋本體向鏈布之長度方向突出。止擋片具備第1片部及第2片部，該第1片部於鏈布之厚度方向中位於第1鏈齒部側，該第2片部於鏈布之厚度方向中位於第2鏈齒部側。又，自鏈布之厚度方向進行觀察，無論第1、第2片部是否相對於第1靠近止擋本體之鏈齒之第2鏈齒部之嚙合部重疊，於止擋附近，為了提昇拉鏈之外觀、提昇止擋相對於鏈布之厚度方向之穩定性，較理想為如下般。即，自鏈布之厚度方向進行觀察，第1片部相對於第1靠近止擋本體之鏈齒之第2鏈齒部之嚙合部重疊，第2片部遠離第1靠近止擋本體之鏈齒之第2鏈齒部之嚙合部。又，於鏈布之長度方向及厚度方向上，無論止擋是否與上述第1、第2靠近之鏈齒相接、是否為一體，於止擋附近，為了提昇止擋相對於鏈布之厚度方向之穩定性，確保拉鏈之厚度方向之彎曲性，較理想為如下般。即，於鏈布之長度方向上，止擋本體遠離上述第1靠近之鏈齒，止擋片遠離上述第2靠近之鏈齒，於鏈布之厚度方向上，第1片部與上述第1靠近之鏈齒之嚙合部相接。又，於鏈布之長度方向上，無論止擋片之最大尺寸L、上述第1靠近之鏈齒與止擋本體之最小間隔S1、及上述第2靠近之鏈齒與止擋本體之最小間隔S2之關係如何，於止擋附近，為了提昇拉鏈之外觀，較理想為如下般。即，設為S1＜L＜S2。又，於一對鏈布之對向之方向上，無論止擋片之最大尺寸W2與第1鏈齒部之最大尺寸W1之關係如何，於止擋附近，為了提昇拉鏈之外觀，較理想為如下般。即，設為W2≦W1。又，於拉鏈除具備一對拉鏈鏈帶及止擋之外，還具備沿一對拉鏈鏈帶之對向之側緣部移動之滑件之情形時，為了使滑件儘量向止擋方移動，較理想為如下般。拉鏈係設為除具備一對拉鏈鏈帶及止擋以外還具備滑件者。滑件具備：一對翼板，其等於鏈布之厚度方向對向；及連結柱，其於鏈齒彼此之間將一對翼板連結。一對翼板係設為可於其內部空間收容止擋。 [發明之效果] 根據本發明之拉鏈，止擋具備止擋本體及止擋片，因此，若與先前之止擋(僅由止擋本體構成之止擋)相比，則第2靠近止擋本體之鏈齒與止擋之間隙變窄有止擋片之量，從而止擋附近之拉鏈之外觀提昇。而且，根據本發明之拉鏈，若與先前之止擋(僅由止擋本體構成之止擋)相比，則止擋相對於鏈布之安裝面積增加止擋片之量，而且止擋片於第1、第2片部自厚度方向隔著鏈布，因此，止擋相對於鏈布之安裝強度提昇。又，根據自鏈布之厚度方向進行觀察，使第1片部相對於第1靠近止擋本體之鏈齒之第2鏈齒部之嚙合部重疊，且使第2片部遠離第1靠近止擋本體之鏈齒之第2鏈齒部之嚙合部之滑件，與例如第1片部不與該嚙合部重疊之滑件相比，於止擋附近，可實現拉鏈之外觀之提昇、及止擋相對於鏈布之厚度方向之穩定性之提昇。又，只要為於鏈布之長度方向上，使止擋本體遠離上述第1靠近之鏈齒，且使止擋片遠離上述第2靠近之鏈齒，於鏈布之厚度方向上，使第1片部與上述第1靠近之鏈齒之嚙合部相接之拉鏈，則於止擋附近，可確保拉鏈之厚度方向之彎曲性並且使止擋相對於鏈布之厚度方向之穩定性提昇。又，根據於鏈布之長度方向上，將止擋片之最大尺寸L、上述第1靠近之鏈齒與止擋本體之最小間隔S1、及上述第2靠近之鏈齒與止擋本體之最小間隔S2之關係設為S1＜L＜S2之拉鏈，若與例如設為S1＞L之拉鏈相比，則上述第1靠近之鏈齒與止擋本體之間隙較窄，因此，於止擋附近，拉鏈之外觀提昇。又，根據於一對鏈布之對向之方向上，將止擋片之最大尺寸W2與第1鏈齒部之最大尺寸W1之關係設為W2≦W1之拉鏈，若與例如設為W2＞W1之拉鏈相比，則於止擋附近，止擋片不會較鏈齒更向一對鏈布之對向之方向突出，因此，可提昇拉鏈之外觀。又，只要為除具備一對拉鏈鏈帶及止擋以外還具備滑件，且可於滑件之一對翼板之內部空間收容止擋之拉鏈，則可使滑件移動直至其連結柱碰撞於止擋為止，因此，於碰撞於止擋之狀態下，可使滑件與止擋之一體感提昇，從而可提昇拉鏈之外觀。[Problems to be Solved by the Invention] Since the sprocket is engaged with the opposing sprocket, the fixed position relative to the length direction of the chain cloth is shifted from one chain cloth and the other chain cloth. Therefore, even if it is the sprocket that is closest to the stop among the plurality of sprockets fixed to each chain cloth, it is the sprocket that is fixed to one of the chain cloths is close to the stop and the sprocket that is fixed to the other chain The second approached the stop. In addition, the stop is a shape extending in the direction opposite to the pair of chain cloths. Therefore, the gap between the second approaching sprocket and the stop is much larger than the gap between the first approaching sprocket and the stop. The nearby appearance has an adverse effect. In addition, the stopper is a person who joins a pair of chain fabrics. Therefore, it is more desirable that the stopper has a higher installation strength with respect to the chain fabric. The present invention has been completed in consideration of the above-mentioned actual situation, and the purpose thereof is to improve the installation strength of the stopper for joining a pair of zipper chain belts, and to improve the appearance near the stopper. [Technical means to solve the problem] The slide fastener of the present invention includes: a pair of fastener chain straps; and a stopper that joins the two at one end portion in the longitudinal direction of the pair of fastener chain straps. A pair of fastener chain belts includes a pair of chain cloths, and a plurality of chain teeth, which are fixed along respective side edge portions of the pair of chain cloths facing each other. The sprocket includes a first sprocket portion and a second sprocket portion. The first sprocket portion is located in one of the thickness directions of the chain cloth and cannot mesh with the opposing sprocket. The second sprocket portion is located on the chain cloth. The other side in the thickness direction, and meshes with the opposing sprocket. The second sprocket portion includes a second base portion that is fixed to the chain cloth, and an engaging portion that protrudes from the second base portion toward the facing chain cloth and meshes with the facing sprocket. The first sprocket portion includes: a first base portion that is fixed to the chain cloth; and a first protruding portion that protrudes from the first base portion toward the facing chain cloth, and a portion of which is opposite to the meshing portion of the facing sprocket. The chain cloths overlap in the thickness direction. The stopper is provided with a stopper body and a stopper piece. The stopper body joins a pair of chain cloths and extends in a direction opposite to the pair of chain cloths. The stopper piece is relatively close to the sprocket teeth of the second stopper body. The self-stop body protrudes in the length direction of the chain cloth. The stopper includes a first piece portion and a second piece portion. The first piece portion is located on the first sprocket portion side in the thickness direction of the chain cloth, and the second piece portion is located on the second chain in the thickness direction of the chain cloth. Tooth side. In addition, when viewed from the thickness direction of the chain cloth, whether the first and second pieces overlap with the meshing portion of the second sprocket portion of the first sprocket close to the stopper body or not, near the stopper, in order to improve the zipper The appearance and stability of the lifting stop relative to the thickness direction of the chain cloth are preferably as follows. That is, when viewed from the thickness direction of the chain cloth, the first piece portion overlaps with the meshing portion of the second sprocket portion of the first sprocket element close to the stopper body, and the second piece portion is away from the first closer to the stopper chain. The meshing portion of the second sprocket portion of the tooth. In addition, in the length direction and thickness direction of the chain cloth, regardless of whether the stopper is in contact with the above-mentioned first and second approaching sprocket teeth or integrated, it is near the stopper in order to increase the thickness of the stopper relative to the chain cloth. The stability in the direction ensures the bendability in the thickness direction of the zipper. That is, in the length direction of the chain cloth, the stopper body is far away from the first approaching sprocket, and the stopper piece is far away from the second approaching sprocket. In the thickness direction of the chain cloth, the first piece portion and the first The meshing portions of the adjacent teeth are connected. In addition, in the length direction of the chain cloth, regardless of the maximum size L of the stopper piece, the minimum distance S1 between the first approaching sprocket and the stopper body, and the minimum distance between the second approaching sprocket and the stopper body. What is the relationship between S2, in the vicinity of the stop, in order to improve the appearance of the zipper, it is ideal as follows. That is, it is set to S1 <L <S2. In addition, in the opposite direction of a pair of chain cloths, regardless of the relationship between the maximum size W2 of the stopper piece and the maximum size W1 of the first sprocket portion, it is ideal to improve the appearance of the zipper near the stopper. As follows. That is, it is set to W2 ≦ W1. In addition, when the slide fastener is provided with a pair of fastener chain belts and a stopper, and a slider that moves along the opposite side edge portion of the pair of fastener chain belts, in order to move the slider as far as possible to the stopper side , Ideally as follows. The slide fastener is provided with a slider in addition to a pair of fastener chain and a stop. The slider includes: a pair of wing plates, which are opposite to each other in the thickness direction of the chain cloth; and a connecting post, which connects the pair of wing plates between the chain teeth. The pair of wing plates is configured to receive a stop in its internal space. [Effects of the Invention] According to the slide fastener of the present invention, the stopper has a stopper body and a stopper piece. Therefore, if compared with the previous stopper (a stopper composed only of the stopper body), the second stop is closer to the stopper The gap between the teeth of the body and the stopper is narrowed by the amount of the stopper piece, so that the appearance of the zipper near the stopper is improved. Moreover, according to the zipper according to the present invention, if compared with the previous stop (the stop consisting only of the stop body), the amount of the stop piece relative to the chain cloth mounting area is increased, and the stop piece is The first and second pieces are separated from each other by the chain cloth in the thickness direction, and therefore, the mounting strength of the stopper with respect to the chain cloth is improved. In addition, according to the thickness direction of the self-chain fabric, the first piece is overlapped with the meshing portion of the second sprocket portion of the first sprocket close to the stopper body, and the second piece is distant from the first close stop. The sliding part of the meshing part of the second sprocket part of the sprocket of the stopper body can be improved in the vicinity of the stopper compared with the sliding part of the first piece part which does not overlap the engaging part, and The stability of the stopper relative to the thickness direction of the chain cloth is improved. In addition, as long as the stopper body is away from the first approaching sprocket in the length direction of the chain cloth, and the stopper piece is away from the second approaching sprocket, the first The zipper in which the sheet portion is in contact with the engaging portion of the first close-toothed sprocket can ensure the flexibility in the thickness direction of the zipper near the stop and improve the stability of the stop relative to the thickness direction of the chain cloth. In addition, according to the length direction of the chain cloth, the maximum size L of the stopper piece, the minimum distance S1 between the first approaching sprocket and the stopper body, and the minimum distance between the second approaching sprocket and the stopper body. The relationship between the interval S2 is set to a zipper with S1 <L <S2. If compared with, for example, a z1 with S1> L, the gap between the first approaching sprocket and the stopper body is narrower, so it is near the stopper. The appearance of the zipper is improved. In addition, according to the direction in which a pair of chain fabrics face each other, the relationship between the maximum size W2 of the stopper piece and the maximum size W1 of the first sprocket part is set to a zipper with W2 ≦ W1, and if it is set to W2 for example> Compared with the W1 zipper, the stopper piece does not protrude in the opposite direction of a pair of chain cloths than the chain teeth near the stopper, so the appearance of the zipper can be improved. In addition, as long as the slide fastener is provided with a slide member in addition to a pair of zipper chain belts and a stopper, and the stopper can be accommodated in the inner space of the pair of wing plates of the slide member, the slide member can be moved until its connecting column collides Until the stop, therefore, in the state of collision with the stop, one can improve the physical feeling of the slider and the stop, thereby improving the appearance of the zipper.

1)預先分別製造一對拉鏈鏈帶2、2及滑件3。 2)將滑件3安裝於一對拉鏈鏈帶2、2。 3)於一對拉鏈鏈帶2、2之一對鏈齒排2e、2e之前端部之附近，藉由嵌入成形而製造一對止擋構件5、5。 4)於一對拉鏈鏈帶2、2之一對鏈齒排2e、2e之後端部附近，藉由嵌入成形而製造止擋4。但是，止擋用之模具係如下般。止擋用之模具包含上模及下模，於上模及下模被鎖模之狀態下，於模具內收容一對鏈布2a、2a之對向之側緣部及第1靠近止擋本體40的鏈齒20之頭部28b之一部分，並且使第1靠近之鏈齒20之頭部28b之上表面形成上模與下模之分模線之一部分。附帶而言，如圖2所示，第1靠近止擋本體40之鏈齒20係右側之拉鏈鏈帶2之最後側之鏈齒20，第2靠近之鏈齒係左側之拉鏈鏈帶2之最後側之鏈齒20。藉由如此設定，形成與止擋4為相同形狀之模穴。而且，對模穴內射出熔融樹脂，且於經過特定時間後開模。於開模前，止擋4之第1片部46與第1靠近之鏈齒20之頭部28b於鏈布2a之厚度方向上成為一體。然而，鏈齒20係預先成形者，止擋4為其後成形者，因此，鏈齒20與止擋4之一體狀態較脆弱，例如，由於開模之衝擊而使止擋4之第1片部46與第1靠近之鏈齒20之頭部28b成為分離、相接之狀態，從而完成第一實施形態之拉鏈1。而且，如圖3所示，第一實施形態之拉鏈1之止擋4具備止擋本體40及止擋片45，因此，若與先前之止擋(僅由止擋本體構成之止擋)相比，第2靠近止擋本體40之鏈齒20與止擋4之間隙S3變窄止擋片45之量，於止擋4之附近，外觀提昇。而且如圖4所示，止擋片45於第1、第2片部46、47自上下方向隔著鏈布2a，因此，止擋4相對於鏈布2a之安裝面積增加止擋片45之量，因此，止擋4相對於鏈布2a之安裝強度提昇。又，如圖2、3所示，自上下方向觀察，止擋4使第1片部46之第1片突出部46b相對於第1靠近之鏈齒20之嚙合部28重疊。又，使第2片部47以不相對於第1靠近之鏈齒20之嚙合部28重疊之方式遠離。藉由該構成，本實施形態之拉鏈1與例如第1片部46不相對於該嚙合部28重疊之拉鏈1相比，增加止擋片45之體積量，於止擋4之附近，可提昇拉鏈1之外觀，確保止擋4相對於鏈布2a之厚度方向之穩定性之提昇。而且，如圖4所示，於上下方向上，嚙合部28與第1片部46之第1片突出部46b相接。又，如圖2所示，於前後方向上，止擋本體40遠離第1靠近之鏈齒20，止擋片45遠離第2靠近之鏈齒20。換言之，於止擋本體40與第1靠近之鏈齒20之間形成有間隔。又，於止擋片45與第2靠近之鏈齒20之間形成有間隔。藉由該構成，本實施形態之拉鏈1於將鏈齒20嚙合之狀態下，於止擋4附近確保拉鏈1之厚度方向之彎曲性，並且使止擋4相對於鏈布2a之厚度方向之穩定性提昇。又，如圖3所示，於前後方向上，止擋片45之最大尺寸L、第1靠近之鏈齒20與止擋本體40之最小間隔S1、及第2靠近之鏈齒20與止擋本體40之最小間隔S2之關係為S1＜L＜S2。藉由該構成，本實施形態之拉鏈1若與設為例如S1＞L之拉鏈相比，第1靠近之鏈齒20與止擋本體40之間隙較窄，因此，於止擋4附近拉鏈1之外觀提昇。又，如圖2所示，於左右方向上，止擋片45之最大尺寸W2與第1鏈齒部22之最大尺寸W1之關係為W2≦W1。藉由該構成，本實施形態之拉鏈1若與設為例如W2＞W1之拉鏈相比，於止擋4之附近，止擋片45不較鏈齒20更向左右方向(較圖2中之第2個鏈齒20之左端更靠左側)突出，因此，可提昇拉鏈1之外觀。又，止擋4與滑件3之關係如下。於上下方向上，如圖6所示，止擋片45之最大尺寸T2與一對翼板32、32之最大間隔T1之關係為T2＜T1。又，拉鏈1於上下方向上將止擋4與滑件3之位置關係設為止擋4位於一對翼板32、32內(T2處於T1之範圍內)。又，於左右方向上，止擋4之最大幅尺寸W4與左右之凸緣34、34之最小間隔W5之關係為W5＞W4。又，拉鏈1於左右方向上將止擋4與滑件3之位置關係設為止擋4位於左右之凸緣34、34內(W4處於W5之範圍內)。藉由該構成，若使滑件3後退而使滑件3之連結柱33碰撞於止擋4，則止擋4被收容於一對翼板32、32之內部空間。藉此，可於滑件3碰撞於止擋4之狀態下，使滑件3與止擋4之一體感提昇，從而可提昇拉鏈1之外觀。本發明並不限定於上述實施形態，可於不脫離其主旨之範圍內進行適當變更。例如，止擋本體40之形狀於上述實施形態中為矩形狀，但於本發明中並不限於此，亦可為橢圓狀、梯形形狀等其他形狀。As shown in FIG. 1, a zipper 1 according to a first embodiment of the present invention includes: a pair of zipper chain straps 2 and 2 which are extended in parallel; and a slider 3 which can extend along the pair of zipper chain straps 2 and 2. Moving toward the side edge portion; a stop 4 that defines a moving range of the slider 3 at one end of both end portions in the extending direction (length direction) of the pair of fastener chains 2 and 2; and a pair of stop members 5, 5 which is equal to the other end portion of the two longitudinal end portions of the pair of fastener chain belts 2 and 2 defines the moving range of the slider 3. Moreover, by moving the slider 3 in one of the above-mentioned longitudinal directions, a pair of zipper chain belts 2 and 2 can be opened. When the extreme position of one of the moving ranges is reached, the slider 3 collides with the stop 4 . In addition, by moving the slider 3 in the other direction of the above-mentioned length direction, a pair of zipper chain belts 2 and 2 can be pulled together. When the extreme position of the other side of the moving range is reached, the slider 3 collides with a Pair of stop members 5,5. When describing the following directivity, the longitudinal direction is also referred to as the front-rear direction. The front direction refers to the direction above FIG. 1 and refers to the direction in which the slider 3 pulls a pair of zipper chain belts 2 and 2 together. The so-called rear direction refers to the lower direction in FIG. 1 and refers to the direction in which the slider 3 pulls the pair of zipper chain belts 2 and 2 apart. The opposite direction of a pair of fastener chain belts 2 and 2 means a direction orthogonal to the longitudinal direction (front-rear direction) and in which a pair of fastener chain belts 2 and 2 are arranged, and is also referred to as a width direction or a left-right direction. The left direction refers to the left direction of FIG. 1, and the right direction refers to the right direction of FIG. 1. Further, a direction orthogonal to the front-rear direction and the left-right direction is referred to as a thickness direction or an up-down direction. The so-called upward direction refers to the direction orthogonal to the paper surface of FIG. 1, that is, the direction near the front side of the direction orthogonal to the front-to-rear direction and the left-right direction. direction. A pair of zipper chain belts 2 and 2 includes: a pair of chain cloths 2a, 2a which are extended front to back and aligned to the left and right; and a pair of sprocket rows 2e, 2e, which are aligned along a pair of chain cloths 2a, 2a The left and right side edges are fixed. As shown in FIGS. 1 and 6, the chain cloth 2 a has a long belt shape in front and back, and its thickness direction is up and down. The direction in which the pair of chain cloths 2a and 2a face each other is the left-right direction. The chain cloth 2a has a side edge portion facing the other chain cloth 2a as the core portion 2c. The core portion 2c is thicker in the vertical direction than a portion adjacent to the side edge portion, and the core portion 2c is removed. Parts other than 2c serve as the chain cloth body 2b. The upper and lower surfaces of the chain cloth body 2b are parallel planes (horizontal planes). When viewed from the front-rear direction, the core portion 2c has an elliptical cross-sectional shape that protrudes in both directions of its thickness direction compared to the chain body 2b. Each sprocket row 2e is formed by a plurality of sprocket 20, and the plurality of sprockets 20 are fixed along the opposite side edge portions of the chain cloth 2a at intervals from front to back. The sprocket 20 is made of synthetic resin or metal. When the slider 3 is moved forward in order to pull the pair of zipper chain belts 2 and 2 together, the teeth 20 of the pair of sprocket rows 2e and 2e mesh with each other, and the slider 3 collides with the pair of stops The members 5 and 5 prevent the slider 3 from moving further forward. Further, when the slider 3 is moved backward in order to pull the pair of zipper chain belts 2 and 2 apart, the sprocket teeth 20 of the pair of sprocket rows 2e and 2e are separated from each other in the left-right direction and collided by the slider 3 The stopper 4 prevents the slider 3 from moving further backward. As shown in Figs. 4, 9, and 10, the sprocket 20 includes a first sprocket portion 22 and a second sprocket portion 26. The first sprocket portion 22 is located above the chain cloth 2a and cannot be opposed to the sprocket. 20 is engaged, and the second sprocket portion 26 is located below the chain cloth 2a and meshes (engages and disengages) with the opposing sprocket 20. The first and second sprocket portions 22 and 26 are fixed to the opposite edge portions of the chain cloth 2a so as to sandwich the chain cloth 2a from both sides in the thickness direction. In addition, the first and second sprocket portions 22 and 26 are joined in the up-and-down direction at portions protruding toward the facing cloth 2a from the side edge portions. The single-dot chain lines in FIGS. 9 and 10 indicate the inner ends in the left-right direction of the chain cloth 2a (the opposite ends of the pair of fastener chain straps 2 and 2). The second sprocket portion 26 includes a second base portion 27 that is fixed to the chain cloth 2 a and an engaging portion 28 that protrudes from the second base portion 27 toward the facing chain cloth 2 a and meshes with the facing sprocket 20. The lower surface of the second sprocket portion 26 is a plane parallel to the lower surface of the chain cloth body 2b. The second base portion 27 is a portion that is fixed in a form that overlaps with the chain cloth 2a on one surface side in the thickness direction in the left-right direction. The engaging portion 28 is a portion away from the chain cloth 2a in the left-right direction, in other words, a portion that does not overlap with the chain cloth 2a in the thickness direction. More specifically, in the case of the sprocket 20 of the chain cloth 2a fixed to the right in FIG. 4, the second base portion 27 is a portion closer to the right side of the left end of the chain cloth 2a, and the engaging portion 28 is opposed to The left end of the chain cloth 2a. As shown in FIG. 10, the engaging portion 28 includes a neck portion 28a protruding from the second base portion 27 toward the facing chain cloth 2a, and a head portion 28b protruding from the neck portion 28a toward the facing chain cloth 2a, and It protrudes forward and backward from the neck 28a. The neck portion 28a and the head portion 28b are provided with a pair of recessed portions 28c, 28c which are recessed in the left-right direction with respect to each other at both ends in the front-rear direction. The recessed portion 28c is arc-shaped. The neck portion 28a is a portion that gradually narrows toward both ends in the front-rear direction as it moves away from the chain cloth 2a. The head portion 28b is a portion that gradually narrows toward the outer side in the front-back direction as it moves away from the neck portion 28a. In addition, when viewed from the up and down direction, the outer shape of the head portion 28b is C-shaped. As shown in FIGS. 4, 9, and 10, the first sprocket portion 22 includes: a first base portion 23 that is fixed to the chain cloth 2 a; and a first protruding portion 24 that faces the opposite chain cloth 2 a from the first base portion 23. It protrudes, and a part thereof overlaps the meshing portion 28 of the opposing sprocket 20 in the vertical direction. The upper surface of the first sprocket portion 22 is a plane parallel to the upper surface of the chain cloth body 2b. When viewed in the up-down direction, the first sprocket portion 22 has a rectangular shape, and more specifically, a square shape. The extension direction of two sides of one of the two parallel groups forming a square is set to the front-back direction. The extension direction of the other two sides is set to the left and right directions. Furthermore, in each fastener chain 2, the first sprocket portion 22 of each sprocket 20 faces the first sprocket portion 22 of an adjacent sprocket 20 in the front-rear direction.

Furthermore, the left side surface 47i of the second piece portion 47 is formed so as to diagonally cross the left side surface 46i of the first piece portion 46 as viewed from below. The slide fastener 1 of the said 1st Embodiment is manufactured as follows, for example. 1) A pair of fastener chain straps 2 and 2 and a slider 3 are separately manufactured in advance. 2) Attach the slider 3 to a pair of fastener chain belts 2 and 2. 3) A pair of stopper members 5 and 5 are manufactured by insert molding near the front ends of a pair of sprocket rows 2e and 2e of a pair of fastener chain straps 2 and 2. 4) A stopper 4 is manufactured by insert molding near the rear end of one of the pair of fastener chain rows 2e and 2e of the pair of fastener chains 2 and 2. However, the stopper mold is as follows. The stopper mold includes an upper mold and a lower mold. In a state where the upper mold and the lower mold are clamped, a pair of chain fabrics 2a and 2a on the opposite side edges and the first approaching stopper body are accommodated in the mold. A part of the head 28b of the sprocket 20 of 40 is formed, and the upper surface of the head 28b of the first close sprocket 20 forms a part of a parting line of the upper mold and the lower mold. Incidentally, as shown in FIG. 2, the first sprocket 20 near the stopper body 40 is the last sprocket 20 on the right side of the fastener chain 2, and the second sprocket is the left zip fastener 2 on the left side. The rear side of the sprocket 20. With this setting, a cavity having the same shape as the stopper 4 is formed. Then, molten resin is injected into the cavity, and the mold is opened after a specific time has elapsed. Before the mold is opened, the first piece portion 46 of the stopper 4 and the head portion 28b of the first approaching sprocket 20 are integrated in the thickness direction of the chain cloth 2a. However, the sprocket 20 is a preformer, and the stopper 4 is a follower. Therefore, one of the sprocket 20 and the stopper 4 is weak. For example, the first piece of the stopper 4 is caused by the impact of the mold opening. The portion 46 and the head portion 28b of the first approaching sprocket 20 are separated and connected to each other, thereby completing the slide fastener 1 of the first embodiment. As shown in FIG. 3, the stopper 4 of the zipper 1 of the first embodiment includes a stopper body 40 and a stopper piece 45. Therefore, if the stopper 4 is the same as the previous stopper (the stopper composed only of the stopper body), In contrast, the gap S3 between the second sprocket 20 and the stopper 4 near the stopper body 40 is narrowed by the amount of the stopper piece 45, and the appearance is improved near the stopper 4. Furthermore, as shown in FIG. 4, the stopper piece 45 is separated from the first and second piece portions 46 and 47 by the chain cloth 2a from the up and down direction. Therefore, the mounting area of the stopper 4 with respect to the chain cloth 2a is increased. Therefore, the mounting strength of the stopper 4 relative to the chain cloth 2a is improved. As shown in FIGS. 2 and 3, the stopper 4 overlaps the first protruding portion 46 b of the first piece portion 46 with respect to the meshing portion 28 of the first approaching sprocket 20 as viewed in the vertical direction. Further, the second piece portion 47 is separated from each other so as not to overlap the meshing portion 28 of the first approaching sprocket 20. With this structure, the zipper 1 of the present embodiment can be increased in the vicinity of the stopper 4 by increasing the volume of the stopper piece 45 compared with the zipper 1 in which the first piece portion 46 does not overlap with the engaging portion 28, for example. The appearance of the zipper 1 ensures the stability of the stopper 4 with respect to the thickness direction of the chain cloth 2a. As shown in FIG. 4, the engaging portion 28 is in contact with the first protruding portion 46 b of the first piece portion 46 in the vertical direction. In addition, as shown in FIG. 2, in the front-rear direction, the stopper body 40 is away from the first approaching sprocket 20 and the stopper piece 45 is away from the second approaching sprocket 20. In other words, a gap is formed between the stopper body 40 and the first approaching sprocket 20. A gap is formed between the stopper piece 45 and the second approaching sprocket 20. With this configuration, in the state where the fastener element 20 is engaged with the fastener element 20 in this embodiment, the flexibility of the thickness direction of the fastener element 1 is secured near the stopper 4 and the thickness of the stopper 4 with respect to the thickness direction of the chain cloth 2a is ensured. Improved stability. As shown in FIG. 3, in the front-rear direction, the maximum size L of the stopper piece 45, the minimum distance S1 between the first approaching sprocket 20 and the stopper body 40, and the second approaching sprocket 20 and the stopper. The relationship between the minimum interval S2 of the body 40 is S1 <L <S2. With this configuration, if the zipper 1 of the present embodiment has a narrower gap between the first approaching sprocket 20 and the stopper body 40 than the zipper with S1> L, for example, the zipper 1 is near the stopper 4. The appearance is improved. As shown in FIG. 2, the relationship between the maximum dimension W2 of the stopper piece 45 and the maximum dimension W1 of the first sprocket portion 22 in the left-right direction is W2 ≦ W1. With this configuration, if the zipper 1 of the present embodiment is closer to the stopper 4 than the zipper set with, for example, W2> W1, the stopper piece 45 does not move more laterally than the sprocket 20 (more The left end of the second sprocket 20 protrudes further to the left), so that the appearance of the zipper 1 can be improved. The relationship between the stop 4 and the slider 3 is as follows. In the vertical direction, as shown in FIG. 6, the relationship between the maximum dimension T2 of the stopper piece 45 and the maximum interval T1 of the pair of wing plates 32 and 32 is T2 <T1. Moreover, in the slide fastener 1, the positional relationship of the stopper 4 and the slider 3 is set in the up-down direction, and the stopper 4 is located in a pair of flaps 32 and 32 (T2 exists in the range of T1). In the left-right direction, the relationship between the maximum width W4 of the stopper 4 and the minimum interval W5 between the left and right flanges 34 and 34 is W5> W4. Moreover, in the slide fastener 1, the positional relationship of the stopper 4 and the slider 3 in the left-right direction is set so that the stopper 4 is located in the left and right flanges 34 and 34 (W4 is in the range of W5). With this configuration, when the slider 3 is moved backward and the connecting post 33 of the slider 3 collides with the stopper 4, the stopper 4 is accommodated in the inner space of the pair of wing plates 32 and 32. Thereby, when the slider 3 collides with the stopper 4, one of the sliders 3 and the stopper 4 can improve the physical feeling, thereby improving the appearance of the zipper 1. The present invention is not limited to the above-mentioned embodiments, and can be appropriately changed without departing from the spirit thereof. For example, the shape of the stopper body 40 is rectangular in the above embodiment, but it is not limited to this in the present invention, and may be other shapes such as an oval shape, a trapezoidal shape, and the like.
