Description of the Invention: [Technical Field of the Invention] The present invention relates to an open-ended zipper that can be opened in an open state without relying on a sliding operation of a slider. [Prior Art] First, the following zipper is well known, and the zipper in which the pair of left and right sprocket rows are engaged can be separated in a moment without sliding operation of the slider. A zipper including a pair of left and right chain belts, which are arranged with a chain of teeth along opposite ends of the chain cloth, and a slider, are disclosed in Japanese Patent Publication No. 55-71135 (Patent Document No.). The pair of left and right sprocket rows are inserted through the sprocket guiding passage, and the key row is switched into the meshing state and the separated state by sliding along the sprocket row; the opening and closing fittings are installed on the left and right sides a latch on one end side of the pair of straps and a tailing cylinder; and an upper opening member for temporarily closing the sliding member to close the other end opposite to the end side after the opening and closing of the opening and fitting member side. The zipper described in the patent document 1 is attached to the upper end of the upper chain, and the fastener element row is extended, and the slider is slidably attached to the front end of the front end of the element row. Above the stop. On the other hand, in the front side of the opening member of the other chain belt, a slider portion is formed which is formed by removing the core portion of the element row and the chain cloth and forming a thin portion. In the zipper described in Patent Document 1, when the zipper is opened and closed by sliding of the slider, the slider is slidably attached between the upper and the detachable fittings attached to the fastener tape. By this sliding action, the H6770.doc 201110902 chain can be brought into an engaged state or a disengaged state. Further, the zipper of the slinger can be quickly opened to the zipper without relying on the sliding operation of the slider. When the pull button is quickly separated into a disengaged state by the sliding action of the slider, the slider is first slid over the upper opening to the front end side, and the slider is abutted against the upper end of the chain. In a state where the slider is slid to a position where it abuts against the upper stopper, the chain on which the side of the element row is attached holds the slider. However, since the slider-inserted edge portion from which the element row and the core portion are removed is formed to be thinner than the thickness of the chain cloth, it can be detached through the link passage path formed along the edge of the side guide of the slider. Therefore, in a state where the slider is slid to a position in contact with the upper stopper, the sliding member can be slid away from the direction in which the front end sides of the pair of right and left links are pulled apart from each other. The rim is detached from the element guiding passage of the slider. If the sliding member is detached from the sliding member, the sprocket row of the zipper in the engaged state can be gradually separated. If the teeth rows are completely separated from each other, the pins can be ejected from the open end of the fitting. If the tail cylinder of the open-away fitting member is withdrawn from the latch, the left and right chain belts are completely separated from each other, and the separation from the upper stopper side as described above is referred to as a top-opening type zipper. As described above, according to the zipper described in Patent Document 1, when it is necessary to quickly separate the zipper, it is necessary to slide the slider until it passes over the upper opening to abut against the upper stopper, and then to the front end side of the pair of right and left links Apply force in the direction in which they are pulled apart from each other. Furthermore, the zipper can be applied to the closing use of the left and right front and back of the top. 146770.doc 201110902 Further, a zipper comprising a pair of left and right chain belts, such as a chain of teeth arranged along opposite ends of the chain cloth, is disclosed in the specification of Patent No. 2,423,202 (Patent Document 2); And a sliding member, wherein the pair of left and right key teeth are arranged to pass through the sprocket guiding passage, and the element row is switched to the engaged state and the separated state by sliding along the element row. A stopper is attached to the sliding end of the meshing side of the fastener element in the chain link of one of the fasteners (referred to as "stringerlO" in Patent Document 2) (Patent Document 2) In contrast to this, the other end of the sprocket row (the suffix is stnngerli in Patent Document 2) is formed in the front of the front end of the element row, and the sprocket row is formed to be thin. The inlaid edge portion (referred to as separator 7 in Patent Document 2), and the end portion of the slider is formed to have the slider temporarily + stopped at the rear of the sliding end of the slider. (Patent Document 2 is referred to as a convex portion of a projection knobs 26'). In the slide fastener described in Patent Document 2, the key is opened by sliding with the slider. In the normal use method, the slider is slid in a range further than the opening on the chain π. By this sliding action, the zipper can be brought into an engaged state or a disengaged state. When the zipper in the sprayed state is quickly separated from the sliding state by the sliding action of the slider, the first zipper is in a state in which the slider abuts the upper opening: (Fig. 1 of Patent Document 2) In the state), and pulling out the sliding member from the edge of the sliding member of the sliding member, the sliding edge is separated from the edge portion. #本—, as shown in Fig. 2 of the patent document, is a portion of the slider embedded from the edge portion of the sliding member. The state in which the link passage is extended. 146770.doc 201110902 Next, the operation of sliding the slider to the front end side is performed, and after the slider is brought into contact with the upper stop ', the trailing path of the slipper from the slider will be The sliding member is pulled out from the edge portion. By performing the series of t, the sliding member can be detached from the sprocket guiding passage of the slider as shown in Fig. 3 of Patent Document 2. Then, the sprocket row in the squirting state can be gradually separated by the splicing of the left and right stalks. The Japanese Patent Publication No. Sho 28-28715 (Patent Document 3) discloses the following. a zipper, the zipper includes a pair of left and right chain belts, and the chain is disposed along a pair of opposite ends of the chain cloth And a sliding member that passes the pair of left and right chain teeth through the element guiding passage ' and switches the element row to the engaged state and the separated state by sliding along the element row. On the side of the detachment of the zipper A stopper for locking the slider to the meshing sliding end is attached to the front side of the front end of the element row on the fastener tape (referred to as a sleeve 52 in Patent Document 3). In the zipper, when the common use method of zipper opening and closing with sliding of the sliding member is used, the sliding member is slid in a range further than the upper end of the chain, so that the zipper is brought into an engaged state or a separated state. On the other hand, when the zipper in the engaged state is quickly separated into a disengaged state by the sliding operation of the slider, the zipper is brought into a state in which the slider abuts against the upper member (Patent Document 3) In the state shown, the slider is rotated substantially in the direction away from the upper stopper (counterclockwise rotation in the embodiment shown in Patent Document 3). Thus, as shown in Fig. 8 of Patent Document 3 , the side guide of the slider ( In Fig. 7 shown in Patent Document 3, the flange 56) can pass through the upper stopper (described in Fig. 7 shown in Patent Document 3 as a sleeve 146770.doc 201110902 member 52) and the front end of the fastener element (in The drawing shown in Patent Document 3 is between the uppermost engaging members 53), so that the chain belt is detached from the chain of the sliding member through the road scale. [Prior Art Document Patent Literature Patent Literature 1 Japanese Patent Publication No. 2, 423, No. 2, No. 2, No. 2, No. 2, No. 2, No. 2, No. 2, No. 2, No. In the above-described Patent Document 1 and Patent Document 2, the pull key is opened and closed by the ordinary use method of the slider sliding, and the member slides in the range before the slider reaches the meshing sliding end (for example, The embodiment described in the first embodiment is within the range between the opening and the opening and closing of the fitting. The reason is that if the sliding member is slid to the engaging sliding end of the zipper (the state abutting with the upper end bearing) is ± 'the sliding member is separated from the edge portion, and the sprocket of the sliding member is guided to the lining, thereby causing the zipper. Deviate from the intention of the deaf. In addition, conversely, when the zipper in the engaged state is quickly separated into a separate shape: first, the sliding member is slid to the meshing sliding position beyond the normal use range, and the person must perform the front end side of the pair of left and right chain belts to each other. Pull the left and right operations. That is, there is a failure that the zipper cannot be opened instantly. In the zipper of the patent document 3, when the slider is rotated counterclockwise to disengage a chain from the slider, it is necessary to pass the side guide of the slider through the J-way. Between the 卩 and the front end of the chain teeth. Thus, the operation of the side guide of the slider 146770.doc 201110902 through the front stop and the front end of the fastener is practically not easy, and the possibility of hindering the quick opening of the zipper is high. The present invention has been developed in view of the above problems, and aims to provide a zipper which is slidable to the spray sliding end in a normal use state in which the slide member is slidably opened and closed. When the zipper is quickly brought into a disengaged state, the slider can be rotated in the direction of the slidable end side of the pair of left and right chain belts while being held in the sliding end of the saliva, thereby quickly opening away The zipper. Means for Solving the Problems In order to achieve the above object, the zipper of the present invention comprises: a pair of right and left work pieces and a second chain link, which are attached with a chain of teeth, and a slider which arranges the above-mentioned key teeth. To be engaged and disengaged; the retaining member for the slider is disposed at an engagement side end of the element row of the second key band; and the release member is disposed opposite to the holding member And the detaching member is retracted from the sliding member in a state in which the sprocket row is coupled, and the sprocket is slidable from the splicing side end according to the slider The zipper is characterized in that: the holding member includes a positioning portion for positioning and holding the slider; the detaching member has a transverse abutting body at an end portion of the element row side; and the transverse abutting system is slidable When the member is held by the positioning portion and is subjected to the transverse force in the width direction of the chain, the member is brought into contact with the fresh plate disposed on the slider, and is held in the slider and the first and the first When the separation member moves relative to the holding member in the end portion of the engagement side of the 2 chain belt, the transverse abutting body is withdrawn from the engagement opening of the slider. It is preferable that the holding member includes a slider holding portion that holds the slider in the second chain belt, and the positioning portion is formed in the slider holding portion. Preferably, the holding member comprises a positioning ridge portion abutting the inner surface of the lower wing of the sliding member to the inner surface of the sliding member, and the positioning or the holding member may include a guiding device connecting the upper and lower blades of the sliding member. The positioning convex portion 'to which the column abuts is the positioning portion, or may include an insertion portion for inserting a stopper claw disposed on the slider as the positioning portion. In the rut, at least one of the disengaging member and the retaining member includes a deployment protrusion disposed between the positioning and holding of the slider: between the lead post and the engagement opening and from the first chain The belt or the opposite side of the second chain T protrudes toward the opposite end edge of the opposite chain. Preferably, the detachment member includes a deployment reinforcement portion located in the guide passage of the immersed cattle held by the cockroaches, and along the opposite end of the sliding end side of the first lapse The gusset is integrally formed with the above-mentioned (four) contact body, and the holding member includes a deployment reinforcing portion which is disposed opposite to the engagement sliding end side of the second chain ▼, and the first key f side The unfolding reinforcing portion is formed to pass through the thickness of the chain passing path formed by the side guides. In this case, it is preferable that the separating member is formed in the vicinity of the positioning and holding member. The chain cloth reinforcement on the chain cloth surface #, H Huaqiu sight!·, +. W π 5$ 邛, and the above-mentioned chain cloth reinforcement (4) The upper Yang-cut abutting body is integrated with the above-mentioned exhibition (four) part. It is preferable that the holding member includes the sliding member that moves the sliding end of the slide 146770.doc 201110902, and the slider holding member is coupled to the front stopper portion. Preferably, the above-mentioned holding member is formed in the description The key cloth reinforcing portion on the key cloth surface in the vicinity of the piece, and the key cloth: the other end portion of the slider holding portion is integrated with the front side. Inverse, and, the effect of the invention is the zipper of the present invention. A meshing-side end portion of the chain element row of the two-chain belt is provided with a holding member, and a separating member is disposed on the first chain belt so as to oppose the holding member. Further, the retaining member includes positioning the slider in its sound. Therefore, when the zipper is quickly opened to the open state without relying on the sliding operation of the slider, the slider can be prevented from being on the meshing sliding end side of the first and second chain belts which are deployed to the left and right. When the end portion is rotated in the direction of the end portion, it is moved toward the side of the separation sliding end. Further, the end portion of the disengagement member on the side of the sprocket # has a cross-cut abutting body, and the slider is positioned and held by the positioning portion (four) In the state of the sliding end, the lateral (four) joint disposed on the detaching member is in a state of entering the inside of the sprocket guide material by a certain amount from the rear end of the side guide of the slider. Therefore, for example, even if the holding member is The width of the chain fabric separated by the separation member The shearing force acting on the zipper 'can also be held in the sliding member by crossing the abutting body against the side guide of the sliding member' to subject the zipper to a specific transverse shear force. When the end portions of the first and second chain belts are engaged with the sliding end side, the detaching member is relatively rotatable relative to the holding member in the direction in which the belt is unfolded in the plane of the chain cloth, and the cross-cut abutting body is movable in the chain of the sliding member 146770.doc 201110902 The window guiding passage rotates to disengage, and the cross-cut abutting body that is obtained can be disengaged from the meshing opening t of the element guiding passage. Especially when the β is transversely abutted The body has a sliding contact with the side guide plate when the detaching member is rotated, and the length of the chain cloth can be rotated on the one hand.

D D Further, if the sliding end of the sliding member (four) slightly leaves the separating sliding end side, the transverse abutting body of the first chain belt enters the engaging passage of the sliding element from the engaging opening of the sliding member. In this manner, even when the detaching member is rotationally moved in the direction of the end portion of the first and second key belts on the side of the spray-sliding end side of the spread (five), the cross-contact abutting body cannot be made. The toothed joint is disengaged, so that the zipper cannot be separated. Further, the EI holding member includes a slider holding portion that holds the slider and maintains the slider in a stopped state, and a positioning portion is formed in the slider holding portion. In this way, when the slider is moved to the slidable sliding end, the positioning of the phantom can be performed by the positioning portion, and the slider can be held more stably by the slider holding portion. Therefore, when the zipper is quickly opened to the open state without relying on the slider and the pawn, the slider can be more reliably prevented from moving. In addition, since the holding member includes the squat ridge portion abutting against the inner surface of the flap or the inner surface of the lower flap as the positioning portion, even if the detaching member is rotated relative to the holding member toward the unfolding direction, The slider can be stably positioned and held at the meshing sliding end. ^ Also 'also because the holding ceremony ─> μ member includes a positioning convex portion that abuts the guide post of the slider as a positioning portion, or goes, 6 ^ includes a stopper 146770 embedded in the slider .doc -12- 201110902 The claws are embedded in 咅P, Jt/c. Since the 乍 is the positioning portion, even if the detaching member is rotationally moved in the unfolding direction with respect to the holding member, the slider can be stably positioned and held at the engaging sliding end. Further, at least the "disengagement member and the holding member" include an unfolding convex portion which is disposed at the guide post of the slider held at the engaging sliding end and the first chain τρ» or the second chain belt. The opposite end edge of the opposite end belt is opposite to the opposite end edge, so that the slider can be slid to the side of the separation sliding end, thereby reducing the operating force at the time of the normal closing operation. Further, the detaching member is included in the guiding passage of the slider sliding to the engaging sliding end, the expansion reinforcing portion 'and/or the holding member extending along the opposite end edge of the first chain belt and extending integrally with the transverse abutting body The deployment reinforcing portion is disposed along the opposite end edge of the engagement sliding end side of the second chain belt. Since A, when the detaching member is rotationally moved in the unfolding direction, the deformation occurring in the chain fabric on the first sprocket side can be reduced. Therefore, a specific opening angle can be obtained with a small amount of opening, so that the zipper can be easily separated. In this case, the detaching member includes a chain reinforcing portion formed by positioning the key sheet surface held in the vicinity of the sliding member on the engaging side sliding end, and the chain reinforcing portion connects the shackle abutting body and the expansion reinforcing portion. One. Therefore, when the zipper is quickly opened to the open state without depending on the sliding operation of the slider, the detaching member is rotatably moved in the unfolding direction, so that the zipper can be smoothly opened. Further, the holding member includes a rear side holding portion that stops the slider that moves to the engagement side sliding end, and one end of the slider holding portion is coupled to the front stopper portion. Therefore, the holding member can be integrally formed, and the slider can be reliably stopped to be held by the α-piece holding portion as the reinforced second chain on the damper side sliding end. In particular, the exhibition of the opposite edge of the slider j

146770.doc •16· 201110902 其次，利用圖1、圖3〜圖5說明滑件50及拉片59之構成。 如圖3〜圖5所示，滑件50包括：下翼片53，其形成滑件5〇 之底部；上翼片52，其係平行於該下翼片53且形成滑件50 之上部（OS方向）；以及導引柱50D，其係於左右方向（圖！ 所示之L-R方向）之中央部將下翼片53與上翼片52連接於滑 件50之前方側（FS側）（參照圖3)。 自滑件50之上翼片52及下翼片53之左右兩側緣部，朝對 向之翼片側延長设置有左右之側導板5 0F。於由上翼片 52、下翼片53、及側導板50F所包圍之滑件之内部，形成 有鏈齒導引通路50T，該鏈齒導引通路5〇τ係為俯視呈γ字 型之空間，且***有左右一對第丨鏈齒12排及第2鏈齒13 排。 於滑件50之導引柱50D之左右兩側（L_R方向），分別開口 著鏈齒導引通路50T之導入口

士於，件50之上翼片52之上部（圖4及05所示之〇s方向）， 貫通者拉片59之拉片軸部59A ’且安裝有支持該拉片59自. 如傾斜之拉片支持體56。 圖4及圖5所示之滑件5〇之拉片支持體％係彎曲成側視呈 146770.doc •17- 201110902 3子型之金屬板加工品，且以包圍自滑件5〇之上翼片52突 出之起始端部56B(參照後文說明之圖14)之形式，由前方 (FS方向）之軸承部56P(參照後文說明之圖14)進行軸支撐。 因此，拉片支持體56係以軸承部56P為支點，後方（“方 向）可朝上下方向（OS-US方向）擺動。 於拉片支持體56之後部（RS方向之部分）形成有擋止爪 54，該擋止爪54貫通開設於上翼片52之貫通孔，且可朝滑 件50之鏈齒導引通路50T前進後退。圖5所示之狀態係拉片 支持體56係藉由未圖示之板彈簧、螺旋彈簧等施力機構， 而成為擋止爪54朝下方（US方向）受力之狀態。而且，下降 後之擋止爪54將嵌入至開設於固持構件9〇上之嵌入部94η 中。再者，於該圖5所示之狀態下，滑件5〇係存在於與前 方擋止部91卡合之位置上，且藉由擋止爪54嵌入於嵌入部 94Η中，而使滑件50定位保持於嚙合滑動端。 如圖3所示，導引柱50D之後部（RS方向）係形成為尖楔 狀。因此，可藉由使滑件50朝後方（RS方向）進行滑動而 使處於自嚙合口

其次，利用圖3〜圖5，說明形成於脫離構件8〇上之各部 146770.doc •18· 201110902 分之功能。沿第1鏈帶16之芯部14形成於對向端緣側之展 開強化部82係於滑件50配置於嚙合滑動端之狀態下貫通至 鏈齒導引通路50T内之部分，且為提高芯部14附近之剛性 之部分。 可藉由形成展開強化部82，提高芯部14附近之剛性，而 於在滑件50配置於嚙合滑動端之狀態下，於鏈布丨丨之平面

如圖5所示’展開強化部82之上下方向（〇s_us方向）之厚 度設定為薄於鏈布貫通路徑50G之上下方向（〇s_us方向）之 間隙。因此’展開強化部82可經由鏈布貫通路徑5〇G而相 對俯視呈γ字型之鏈齒導引通路50T進行***拔出。 如圖3所示，自第1鏈帶16之芯部朝對向端緣側突出之 展開凸部83係於滑件50配置於嚙合滑動端之狀態下貫通鏈 齒導引通路50T内之部分。當使滑件50自嚙合滑動端朝後 方（RS方向）滑動時，展開凸部83係先於第1鏈齒12而接觸 導引柱50D，起到使第1鏈帶丨6朝左側（L方向）較大展開之 作用。 可藉由使展開凸部83自第1鏈帶16之芯部14突出，而於 146770.doc 201110902 令滑件50自嚙合滑動端朝後方（RS方向）滑動時，減少下述 故障：於第1鏈帶16展開不足之狀態下，導引柱50D與第j 鏈齒12碰撞，導致滑動阻力增大，使得操作感惡化。 安裝於第1鏈帶16之第1鏈齒12排之前方（FS方向）之對向 端緣的橫切抵接體86係配置於脫離構件80之第1鏈齒12排 側之端部’且於滑件5 0配置於唾合滑動端之狀態下貫通鍵 齒導引通路50T内之部分。 如圖4所示，橫切抵接體86之上下方向（OS-US方向）之厚 度設定為厚於鏈布貫通路控50G之上下方向（OS-US方向）之 間隙’且亦厚於展開強化部8 2。因此，於芯部14沿著俯視 呈Y字型之鏈齒導引通路50T而貫通之狀態下，橫切抵接 體86自内側抵接於側導板5〇f，因此，橫切抵接體86不會 自滑件50之鏈布貫通路徑5〇G脫落。藉此，可使第1及第2 鏈帶16、17彼此朝左右方向（彼此展開之方向）拉伸時，可 承受特疋之橫切力（橫向之拉伸力)。 如圖3所示，於橫切抵接體86之側導板5〇F側之端緣，將 橫切抵接體86向左（L方向）移動時，可與側導板5〇F之内壁 抵接之範圍定義為橫切抵接範圍Lw(參照後文說明之圖9之 放大圖）。又，將側導板50F之後方（RS方向）之端部定義為 側導板後端50R»而且，將於滑件5〇配置於嚙合滑動端之 狀態下，自側導板後端“尺至橫切抵接範圍£评之最前方 (FS方向）部位為止的距離定義為抗橫切卡合尺寸u。 可藉由將該抗橫切卡合尺寸Ls定於特定之尺寸範圍内， 而於滑件50配置於妨滑動端之狀態下，使橫切抵接⑽ 146770.doc •20· 201110902 與最前端之第2鏈齒13嗔合，或使橫切抵接體86自内側抵 接於側導板5〇F，藉此，便可承受特定之橫切力。 又，如後文中利用圖8及圖9所說明，當朝鏈布u之平面 内將左右之第1及第2鏈帶16、17之嚙合滑動端側彼此展開 的方向旋轉時，橫切抵接體86於滑件5〇之鍵齒導引通路 5〇T内進行旋轉’從而脫離與第2鏈齒13之嚙合，並且可使 橫切抵接體86自鏈齒導引通路50丁之嚙合口 5〇u中脫離。 再者，抗橫切卡合尺寸Ls之尺寸範圍，較好的是於第1 及第2鏈齒12、13之安裝間距定義為p時，抗橫切卡合尺寸 Ls設定於P/6_5p/6之範圍。安裝間距p係指安裳於同 一鏈布π上之鏈齒之特定間隔，例如可將鏈齒12、13之前 後方向（FS-RS方向）中央位置與鄰接於該鏈齒i2、13之鏈 齒12、13之相同位置之間的尺寸設為安裝間距p。 於此情況下，當抗橫切卡合尺寸Ls小於p/6時，抗橫切 力下降，導致拉鏈10隨意開離之可能性變高。另一方面， 當抗橫切卡合尺寸Ls超過5P/6時，則即便朝著將拉鏈1〇前 方（FS方向）之左右之第！及第2鏈帶16、叫嗜合滑動端側 彼此展開之方向旋轉，橫切抵接體86亦難以自鏈齒導引通 路50T之嚙合口 50U中脫離的可能性變高。 於第1鏈帶16中，連接橫切抵接體％與展開強化部“而 連結成一體之連結強化部85係用於將展開強化部82及橫切 抵接體86更牢固地安裝於鏈布丨丨的強化構件。又，可藉由 於第1鏈帶16上形成連結強化部85，而於滑件5〇配置於嚙 合滑動端之狀態下，朝將左右之第}及第2鏈帶16、17之嚙 146770.doc 201110902 〇 β動端側之端部彼此展開之方向旋轉時，抑制鏈布丨丨之 變形，因此，可以較少之第丨及第2鏈帶16、17之開離量獲 知特疋之展開角度，從而可易於使橫切抵接體86自鏈齒導 引通路50Τ之嚙合口 50U中脫離。 再者，連結強化部85係以不干擾滑件5〇之側導板5〇F之 方式，對應著側導板50F所通過之部位（即，於側導板5〇F 所通過之部位之下方側），具有薄於鏈布貫通路徑5 之部 刀，又，為了提高其強度及剛性，而增加滑件5〇之側導板 5卯未通過該鏈布貫通路徑50G之上方之部分（滑件5〇之左

部91設定為厚於鏈齒導引通路5〇τ之内部尺寸之實施例。 例如，如後文中所說明之圖19所示，藉由將前方擋止部 491設定為薄於鏈齒導引通路5〇τ之内部尺寸，而使前方擋 止部491進入至鏈齒導引通路5〇τ内，令前方擋止部491之 後端緣部（RS方向端緣部）與滑件5〇之側導板5〇1?之前端部 (FS方向端部）抵接，藉此，亦可使滑件5〇停止於嚙合滑動 端。 如圖4及圖5所示，配置於第2鏈帶17之第2鏈齒13排前部 末端之前方（FS方向）的滑件保持部92係沿第2鏈帶17之對 向側緣而形成，且該滑件保持部92之前端與前方擋止部91 連結。 該滑件保持部92係將其上下方向（〇S-US方向）之厚度設 定為厚於鏈布貫通路徑5〇G之上下方向（〇S-US方向）之間 隙’又’設定為薄於鏈齒導引通路5〇Τ之上下方向（〇S-US

As shown in FIG. 3 to FIG. 5, the slider 50 includes a lower flap 53 which forms the bottom of the slider 5〇, and an upper flap 52 which is parallel to the lower flap 53 and forms a slider. The upper part of the 50 (the OS direction); and the guide post 50D which connects the lower flap 53 and the upper flap 52 to the front side of the slider 50 in the center portion of the left-right direction (the LR direction shown in FIG. FS side) (refer to Fig. 3). The left and right side edges of the flap 52 and the lower flap 53 on the upper side of the slider 50 are extended to the opposite side of the flap. The side guide 50F is formed inside the slider surrounded by the upper flap 52, the lower flap 53, and the side guide 50F, and a sprocket guiding passage 50T is formed. The sprocket guiding passage 5〇 The γ-shaped space is defined in a plan view, and a pair of left and right second sprocket 12 rows and a second sprocket 13 are inserted. The left and right sides (L_R direction) of the guide post 50D of the slider 50 are respectively opened. The inlet port 50S of the sprocket guiding passage 50T. At the end of the sliding member 5〇, the engaging opening 50U of the sprocket guiding passage 50T is opened. The edge edge of the side guiding plate 5〇F is knives, 〇s 玄The side guide 50F is provided with a chain cloth through path 5〇g. The chain cloth through-passage 50G is obtained by taking out the chain cloth 21 in which the rows of the first and second fastener elements 12 and 13 passing through the fastener element guide passage 50 are inserted from the element guide passage 50 to the outside of the slider 5 The gap is the portion of the key cloth 11 that is in sliding contact when sliding (four) is slid. In the upper part of the upper piece 52 of the piece 50 (the direction of the 〇s shown in Figs. 4 and 05), the pull piece shaft portion 59A' of the puller piece 59 is attached and supported to support the pull piece 59. Pull tab support 56. The slider support body of the slider 5 shown in FIG. 4 and FIG. 5 is bent into a metal plate processed product of 146770.doc • 17-201110902 3 sub-side, and is surrounded by the slider 5〇. The front end portion 56B (see FIG. 14 to be described later) in which the flap 52 protrudes is axially supported by the front (FS direction) bearing portion 56P (see FIG. 14 described later). Therefore, the pull tab support 56 has the bearing portion 56P as a fulcrum, and the rear side ("direction" can swing in the vertical direction (OS-US direction). The rear portion of the pull tab support 56 (portion in the RS direction) is formed with a stop. The claw 54 is inserted through the through hole of the upper blade 52 and can be advanced and retracted toward the element guide passage 50T of the slider 50. The state shown in Fig. 5 is by the tab support 56. A biasing mechanism such as a leaf spring or a coil spring (not shown) is in a state in which the stopper claw 54 is biased downward (in the US direction). Further, the lowered pawl 54 is fitted to the holding member 9 Further, in the state shown in Fig. 5, the slider 5 is present at a position where it engages with the front stopper portion 91, and is inserted into the fitting portion 94 by the stopper claw 54. The slider 50 is positioned and held at the meshing sliding end. As shown in Fig. 3, the rear portion (RS direction) of the guide post 50D is formed in a wedge shape. Therefore, the slider 50 can be made rearward (RS Sliding to introduce the self-engaging port 50U into the meshing state of the sprocket guiding passage 5 The row of the first sprocket 12 and the row of the second sprocket 13 are separated in the left-right direction (L_R direction) and are respectively discharged from the inlets of the two. Then, if the slider 50 is directed to the front of the circle 3 (FS) When the direction is slid, the first sprocket 12 and the second sprocket 13 in the separated state are introduced from the respective introduction ports 50S, and are guided by the side guides 50F to be merged, so that the first and the first meshing states can be achieved. The rows of the 2 fastener elements 12 and 13 are discharged from the engagement opening 50U. Next, the functions of the respective portions 146770.doc • 18· 201110902 formed on the release member 8〇 will be described with reference to Figs. 3 to 5 . The development portion 82 of the core portion 14 formed on the opposite end edge side penetrates into the element guide passage 50T in a state where the slider 50 is disposed at the engagement sliding end, and the rigidity of the vicinity of the core portion 14 is increased. In the state in which the expansion reinforcing portion 82 is formed, the rigidity in the vicinity of the core portion 14 can be increased, and in the state in which the slider 50 is disposed at the meshing sliding end, the first and the third sides are made in the plane of the chain fabric. The ends of the meshing sliding end sides of the 2 chain belts 16 and 17 are unfolded from each other 'to make the detaching member 80 relatively fixed When 90 is moved in the opposite direction to the unfolding direction, the deformation of the core portion 14 is suppressed. Therefore, the amount of opening of the first and second key bands 16 and 17 can be reduced, and the specific expansion angle can be known. The cross-cut abutment body 86 is easily detached from the engagement opening 50U of the element guide passage 50T. Therefore, the ... and the second link belts 16, 17 can be easily spread out from each other. The thickness of the direction (〇s_us direction) is set to be smaller than the gap between the upper and lower directions (〇s_us direction) of the chain-passing path 50G. Therefore, the 'expanding and strengthening portion 82 can be γ-shaped in a plan view through the chain-passing path 5〇G. The element guide passage 50T is inserted and removed. As shown in FIG. 3, the unfolding convex portion 83 projecting from the core portion of the first link belt 16 toward the opposite end edge side is a portion that penetrates the inside of the element guide passage 50T in a state where the slider 50 is disposed at the meshing sliding end. . When the slider 50 is slid rearward (RS direction) from the meshing sliding end, the unfolding convex portion 83 comes into contact with the guide post 50D before the first sprocket 12, so that the first link 丨6 faces the left side (L) Direction) The effect of a larger expansion. By causing the unfolding convex portion 83 to protrude from the core portion 14 of the first chain belt 16, when the sliding member 50 is slid from the meshing sliding end toward the rear (RS direction) at 146770.doc 201110902, the following malfunction is reduced: In a state where the 1 chain belt 16 is insufficiently deployed, the guide post 50D collides with the j-th chain tooth 12, resulting in an increase in sliding resistance, which deteriorates the operational feeling. The transverse abutting body 86 attached to the opposite end of the first sprocket 12 of the first chain belt 16 (FS direction) is disposed at the end portion of the first sprocket 12 on the side of the first sprocket 12 of the detachment member 80 Further, the slider 50 is disposed in a portion of the key guide passage 50T in a state where the slider is disposed at the sliding end. As shown in FIG. 4, the thickness of the upper and lower directions (OS-US direction) of the cross-cut abutment body 86 is set to be thicker than the gap of the upper and lower directions (OS-US direction) of the chain-passing path 50G and is also thicker than the unfolding. Strengthening section 8 2 . Therefore, in a state in which the core portion 14 penetrates along the sprocket guide passage 50T having a Y-shape in plan view, the cross-contact abutting body 86 abuts against the side guide 5 〇f from the inside, and thus the transverse contact abuts The body 86 does not fall off from the chain passing path 5〇G of the slider 50. Thereby, when the first and second chain belts 16 and 17 are stretched in the left-right direction (the direction in which they are unfolded), the transverse transverse force (transverse force in the lateral direction) can be withstood. As shown in FIG. 3, when the transverse edge abutting body 86 is moved to the left (L direction) at the edge of the side guide 5 〇F side of the abutting body 86, the side guide 5 〇F can be used. The range in which the inner wall abuts is defined as the cross-cut abutment range Lw (refer to the enlarged view of FIG. 9 described later). Further, the end portion of the side guide 50F (RS direction) is defined as the side guide rear end 50R» and, in the state where the slider 5 is disposed at the meshing sliding end, the rear side of the side guide "foot" The distance to the foremost (FS direction) portion of the cross-cutting range is defined as the cross-cut engagement dimension u. The anti-transverse engagement dimension Ls can be set within a specific size range, and When the slider 50 is disposed at the sliding end, the cross-cut abutting (10) 146770.doc • 20· 201110902 is engaged with the second leading end tooth 13 or the transverse abutting body 86 is abutted from the inner side. The side guides 5〇F, by which the specific transverse force can be withstood. As will be described later with reference to Figs. 8 and 9, the first and second sides will be left and right in the plane of the chain u. When the engaging sliding end sides of the chain belts 16 and 17 are rotated in the direction in which they are unfolded, the cross-cut abutting body 86 is rotated in the key-tooth guiding passage 5T of the slider 5A to be disengaged from the second element 13 Engagement, and the cross-cut abutment body 86 can be disengaged from the engagement opening 5〇u of the element guide passage 50. Further, the size range of the cross-cut engagement size Ls Preferably, when the mounting pitch of the first and second sprocket teeth 12, 13 is defined as p, the cross-cutting engagement dimension Ls is set in the range of P/6_5p/6. The mounting pitch p means that the skirt is in the same chain. The specific spacing of the sprocket on the cloth π, for example, between the center position of the sprocket 12, 13 in the front and rear direction (FS-RS direction) and the same position of the sprocket 12, 13 adjacent to the sprocket i2, 13 The size is set to the mounting pitch p. In this case, when the cross-cutting engagement size Ls is less than p/6, the cross-cutting force is lowered, and the possibility that the zipper 10 is arbitrarily opened is high. When the cross-cutting engagement size Ls exceeds 5 P/6, the second and third chain belts 16 and the second chain belt 16 are swung in the direction in which the front side of the zipper 1 ( (the FS direction) and the accommodating sliding end side are unfolded. It is also difficult for the cut contact body 86 to be detached from the engagement opening 50U of the element guide passage 50T. In the first link belt 16, the cross-cut abutment body % and the expansion reinforcement portion are connected and integrated. The connection reinforcing portion 85 is a reinforcing member for attaching the expansion reinforcing portion 82 and the cross-cut abutting body 86 to the chain fabric more firmly. Moreover, the first reinforcing belt 85 can be formed on the first chain belt 16, and the sliding member 5 can be placed on the meshing sliding end, and the first and second chain belts 16 and 17 can be 146770. Doc 201110902 When the end portions of the 动β moving end side are rotated in the direction in which they are unfolded, the deformation of the chain fabric is suppressed, so that the opening of the third and second chain belts 16 and 17 can be reduced. The angle makes it easy to disengage the cross-cut abutment body 86 from the engagement opening 50U of the element guide passage 50A. Further, the connection reinforcing portion 85 corresponds to a portion through which the side guide 50F passes (that is, a portion through which the side guide 5〇F passes) so as not to interfere with the side guide 5〇F of the slider 5〇. The lower side) has a knife which is thinner than the link passage 5, and in order to increase the strength and rigidity thereof, the side guide 5 of the slider 5 is not passed over the portion of the chain passage 50G (sliding) The thickness of the left side (LR direction) of the piece 5' is thicker than the expansion reinforcement portion 82 (see FIG. 4 and the circle 5). Further, the portion of the connection reinforcement portion 85 where the side guide plates 5〇F are not passed The thickness is set to be thinner than the cross-cut abutment body 86. On the opposite end side of the cross-cut abutting body 86, an engaging end that extends in a hook shape toward the rear (RS direction) and engages with the engaging head portion of the opposing second element 13 is formed by The α-toothed end § 7 is formed in the body 86, and when the first and second chain belts 16, 17 are rotated in the direction in which the left and right first and second chain belts 16 and 17 are unfolded, the engaging end 87 is along the opposite second element 13 The movement around the engaging head promotes the rotation of the unfolding direction. Therefore, the second opening angle of the second and second chain belts 16 and the opening can be reduced to obtain a specific deployment angle, so that the transverse abutting body 86 can be easily made. The sprocket guiding passage 50 is disengaged from the engaging opening 50U. Next, the function of each part formed on the holding member 9A will be described with reference to Figs. 3 to 5 . The front stopper portion 91 disposed further forward (in the FS direction) of the front end of the second chain element 13 of the second chain belt 17 is configured such that the slider 5 is stopped by abutting against one of the sliders The part that engages the sliding end. In the embodiment of 146770.doc -22-201110902 shown in FIG. 3, the outer dimension of the front stop portion 91 in the upper and lower directions (〇s_us direction) is set to be thicker than the upper direction of the element guide passage 50T (〇 Since the inner size of the s_us direction is the state in which the front stopper portion 91 does not enter the element guide passage 50T and is locked. Further, other configurations may be used instead of the embodiment in which the front stopper portion 91 is set to be thicker than the inner dimension of the element guide passage 5? as shown in Fig. 3. For example, as shown in FIG. 19 described later, the front stopper portion 491 is set to be thinner than the inner dimension of the element guide passage 5〇τ, and the front stopper portion 491 is guided to the element guide. In the passage 5〇τ, the rear end portion (the RS direction end edge portion) of the front stopper portion 491 is brought into contact with the side guide 5?1? front end portion (the FS direction end portion) of the slider 5? It is also possible to stop the slider 5〇 from engaging the sliding end. As shown in FIG. 4 and FIG. 5, the slider holding portion 92 disposed in front of the front end of the second element 13 of the second chain belt 17 (FS direction) is along the opposite side edge of the second chain belt 17. The front end of the slider holding portion 92 is coupled to the front stopper portion 91. In the slider holding portion 92, the thickness in the vertical direction (〇S-US direction) is set to be thicker than the gap in the upper and lower directions (〇S-US direction) of the chain through path 5〇G, and is set to be thinner than The internal dimension of the sprocket guiding passage 5 〇Τ in the upper and lower directions (〇S-US direction). Therefore, when the slider holding portion 92 passes through the element guide passage 50 of the slider 5, the slider holding portion 92 can hold the slider 50 to the second link 17, and maintain the stop of the slider 50. status. In the state where the slider holding portion 92 is inserted into the element guide passage 50, the right side (R direction) end portion of the slider holding portion 92 abuts against the side guide 146770.doc • 23· 201110902 plate 50F. Therefore, it does not fall off from the link path 5〇G. Thereby, even if the i-th chain belt 16 is detached from the slider 50, the slider 5〇 can be held on the side of the second chain belt 17. The two unfolding projections 93 projecting from the core portion 14 of the second chain belt 17 toward the opposite end edge are engaged with the portion of the slider 50 disposed in the meshing sliding end through the sprocket guiding passage 50T. When the slider 50 is slid toward the rear (rs* direction) from the meshing sliding end, the unfolding convex portion 93 contacts the guide post 50D before the second sprocket 13, thereby causing the second link 17 to the right (R). Direction) The effect of a larger expansion. The connection reinforcing portion 915 that connects the second chain portion 17 and the rear end portion of the slider holding portion 92 is used to securely attach the front collision portion 91 and the slider holding portion 92 to the chain. The reinforcing member of the cloth 11. By the formation of the connection reinforcing portion 95 on the second chain belt 17, the first and second chain members 16 and 17 which are to be left and right are disposed in a state where the slider 5 is disposed at the meshing sliding end. When the end portions of the toothed sliding end side are rotated in the direction in which they are unfolded, the deformation of the chain cloth 11 is suppressed. Therefore, a smaller degree of opening of the first and second chain belts 16, 17 can be obtained to obtain a specific deployment angle, so that the cross-cut abutment body 86 can be easily detached from the engagement opening 50U of the element guide passage 50T. . Further, the "connection reinforcing portion 95" has a portion thinner than the link passage 50G on the lower side of the portion through which the side guide 50F passes, so as not to interfere with the side guide 50F of the slider 50, and in order to improve it The strength and the rigidity, and the thickness of the portion above the side guide 50F of the slider 50 (the side of the left and right (LR direction) of the slider 50) is increased by the portion above the side guide 50F (see FIG. 4). And Figure 5). 146770.doc -24· 201110902 The upper surface (the surface in the direction of the 〇8 direction) of the rear portion (RS direction) of the slider holding portion 92 is provided with the fitting portion 94H ^ by the slider 5 〇 being disposed at the meshing sliding end The stopper claw 54 on the side of the slider 50 is fitted to the fitting portion 94H, and the slider 50 is positioned and held at the engaging sliding end. For example, when the meshing sliding end sides of the left and right i-th and second chain belts 16 and 17 are rotated in the direction in which they are unfolded, the slider 50 moves toward the rear (RS direction) in accordance with the unfolding operation. At this time, if the slider 50 moves slightly toward the rear (RS direction), the distance from the rear side of the side guide M 50R to the end of the abutment range lw (the anti-cross-cut engagement size shown in FIG. 3) Ls) will increase. If the cross-cut engagement dimension Ls is lengthened, the cross-cut abutment body 86 cannot be disengaged from the engagement opening 50U of the element guide passage 5?. Therefore, in the embodiment shown in FIG. 5, by inserting the stopper claw 54 on the slider 50 side into the fitting portion 9411, the slider is positioned at the meshing sliding end, and the cross-cutting engagement size is Lsk is controlled within a specific size range. Further, the configuration for positioning the slider 5G on the pain-sliding end is not limited to the configuration in which the locking claws 54 are fitted to the fitting portion 94h as shown in Figs. 1 to 3, and other configurations may be used. For example, as will be described later with reference to FIG. 13 and FIG. 3, the following configuration may be adopted: the self-sliding member holding portion 92 is formed in the vertical direction (〇s_US direction) and is formed on the element guide passage (10)T. The positioning ridges 94B (positioning portions) on which the fins and/or the lower fins 53 abut are positioned to hold the sliding (four) at the meshing sliding end.

Furthermore, the positioning portion is configured to move the slider 50 to position the slider 50 so that the slider 5 is not accidentally formed toward the rear of the positioning portion and the slider holding portion 92. Therefore, when the slider 50 is used When the state of the left squat is performed, the slider 5'' can be stably held to surely detach the detachment member 8 from the slider 50. Further, in order to stably hold the slider 5 (), the slider holding portion 92 is formed to be longer than the self-sliding in the longitudinal direction of the chain in a state in which the slider holding portion 92 penetrates the inside of the slider 5'. The length of the 5G guide a5〇S to the end of the 5喷u side of the spray port of the guide column. Next, with reference to Fig. 7 and Fig. 7, the state in which the element rows of the meshing state are gradually separated while the slider 5 is slid rearward (in the direction of the Rs direction and the direction in which the sliding ends are separated) is described. Fig. 6 is a view showing a state in which the slider 5 is slightly slid toward the rear (RS direction) and the first and second chain belts 16 and 17 are slightly unfolded from the state in which the slider 5 is disposed at the meshing sliding end. Plane section view. Fig. 7 is a zipper plan sectional view showing a state in which the slider is slid rearward (RS direction) from the state shown in Fig. 6 and the element rows in the engaged state are gradually separated from each other. In the same portions as those described with reference to Fig. 5, the same reference numerals will be given, and the description thereof will be omitted. If the user holds the pull tab 59 toward the rear (RS direction) while the slider 50 is disposed at the meshing sliding end, the force receiving pawl 54 will face upward by the biasing mechanism. (OS direction) moves. This configuration is generally referred to as the construction of a well-known slider of an automatic slider or a semi-automatic slider 146770.doc -26- 201110902 (refer to Fig. 5). When the stopper claw 54 is moved upward (in the 〇s direction), the stopper claw 54 is disengaged from the fitting portion 94H, and the slider 50 is brought into a state of being slidable from the state of being engaged with the engaging sliding end. When the user moves the pull tab 59 toward the rear (in the RS direction), the slider 50 also slides toward the rear (RS direction). As shown in FIG. 6, when the slider 5 is slid from the meshing sliding end toward the rear (RS direction), the rear end portion of the guide post 50D of the slider 50 first comes into contact with the inclined surface of the unfolding convex portion 93 of the holding member 9A. Then, the second chain belt 17 is unfolded to the right (R direction). Then, the top of the opposite end edge side of the unfolding convex portion 93 is in sliding contact with the right side surface of the guide post 50D, and on the other hand, toward the introduction port 5〇s, thereby making the second chain belt 17 further toward Expand right (R direction). Further, when the slider 50 is slid rearward (in the RS direction), the end portion of the guide post 5〇d is brought into contact with the inclined surface of the unfolding convex portion 83 of the detaching member 80, so that the first link 16 is turned to the left ( L direction) unfolds. Thereafter, the top of the opposite end edge side of the unfolding convex portion 83 slides on the one hand to contact the left side surface of the guide post 5〇D, and on the other hand, faces the introduction port 50S, whereby the first chain belt 16 is further gradually turned to the left. (L direction) expands. When the slider 50 is further slid rearward (RS direction), the inclined faces of the engaging heads of the left and right first and second sprocket 12, 13 will gradually abut against the rear end of the guide post 50D, so that The first and second chain belts 16, 17 are gradually developed in order. If the unfolding convex portions 83 and 93 are not formed at the opposite end edges of the first and second chain belts 16, 17, the guide post 50D is insufficiently deployed on the left and right first and second chain belts 16, 17. In the state, the side surfaces of the first and second sprocket teeth 12 and 13 in front of the meshing head (FS direction) are in contact with each other. As a result, the sliding resistance of the slider 50 is increased by 146770.doc •27·201110902, and the operational feeling is deteriorated. As described above, the first and second sprocket wheels 12 and 13 in the engaged state are guided from the ring mouth 5GU to the element guide passage, and the first and second elements are guided by the guide column. The 12th and 13th rows are separated in the left-right direction (l_r direction), and are respectively discharged from the introduction ports 50S of the two. Next, the operation of the following case will be described with reference to Fig. 8 to the circle 12, in which the slider 50 is placed on the slidable sliding end of the zipper 1 而不 without sliding, (4) and the second chain 16, 16 The sliding sliding end sides are rotated in the direction in which they are unfolded, thereby rapidly opening the zipper 丨〇.

Fig. 12 is a plan view showing the opening and closing fitting 39 attached to the detaching sliding end of the zipper ίο. The same parts are denoted by the same reference numerals and their descriptions are omitted. As shown in Fig. 3, even in the slider 5 When placed in the state of the slidable end, the cutting force of the second and second chain belts 16 1 7 is applied in parallel in the left-right direction (L_R direction), and the tangent abutment body 8 6 will also be from the inner side. The side guide 50F abuts and is held in the slider 5, so that the engagement of the third and second elements 12, 13 with each other can be maintained. 146770.doc • 28· 201110902 In contrast, as shown in Fig. 8 to As shown in FIG. 10, when the slider 50 is disposed at the meshing sliding end, the meshing sliding end sides of the first and second chain belts 16, 17 are unfolded from each other', and the releasing member 80 is moved toward the developing direction with respect to the holding member 90. With respect to the relative rotational movement, the expansion reinforcing portion 82 formed to be thinner than the gap of the chain through-passage path 50G is withdrawn from the chain-through passage 50G. At the same time, the transversely-contacting member 86 will be in sliding contact with the side of the slider 5 The guide plate 50f rotates at the same time, so that the cross-cut abutment body 86 is disengaged from the engagement opening of the element guide passage 50T. At this time, the engagement end 87 is made by the rotation of the abutment body 86. Disengaged from the second sprocket 13', so that it can be brought into engagement at the rear (RS direction) The sprocket rows are in a separated state in sequence, so that the zipper 10 can be quickly opened. If all the first and second sprocket wheels 12 and 13 in the zipper 10 are disengaged and become separated, as shown in the figure. As shown in Fig. 12, the insert body 3 开 which is opened and detached from the fitting member 39 and the body 40 to be inserted are pivotally supported by the shaft portion 32, and are rotated in the direction in which the front side (FS direction) is unfolded. The shaft portion 32 of the body 3 can be detached from the intended body 40, so that the left and right first and second chain belts 16 and 17 can be separated from each other. Further, the second chain belt 17 is embedded in the portion 94H. In the middle, the state in which the stopper claws 54 on the side of the slider 5 are fitted is in the state of the right side. The force is applied in the direction in which the engaging sliding end sides of the second chain belts 16, 17 are unfolded, and the sliding member 50 is prevented from moving rearward (in the RS direction). Thereby, the slider 5 〇 can be held at the meshing sliding end. Further, as shown in Fig. 9, when the i-th and second chain belts 16'17 are made. When the toothed sliding end sides rotate in the direction in which they are unfolded, the meshing end 87 will move along the meshing head (side wall surface) of the second sprocket 13 of the opposite 146770.doc -29-201110902 to promote the cross-cut abutting body. The rotation of 86. Thereby, a smaller number of opening distances of the first and second chain belts 16, 17 can be obtained, and a specific deployment angle can be obtained. Next, another embodiment for preliminarily holding the slider 5 保 on the meshing sliding end will be described with reference to Figs. 13 and 14 . Fig. 13 is a plan sectional view showing a zipper in which an embodiment in which a positioning ridge 94B that abuts against the upper flap 52 of the slider 50 and/or the lower flap 53 is formed in the slider holding portion %.

The starting end portion (10) of the slider supporting body 56 is slidably supported to protrude from the flap 52 above the front portion (FS direction) of the slider 5. The left and right side portions (the side portions in the L-R direction) of the force start end portion 56b are formed with a pivot-shaped bearing portion. The pull tab support 56 is supported by the bearing portion 56p as a fulcrum, and is rotatably supported by the start end portion, and is supported by a stopper claw 54 of the pull tab support 56 by a biasing mechanism (not shown) (refer to the figure). 5) The force is applied in the direction of the entry and exit of the element guide path 5〇τ. Next, another embodiment in which the (four) slider 5G is previously positioned and held at the snap sliding end will be described with reference to FIG. Fig. 15 is a view for explaining an embodiment in which the sliding: 5 〇 is previously positioned and held at the meshing sliding end by locking the slider-side stopper claw 54 to the front (ps direction) end edge of the unfolding convex portion 293.

Thereby, the second and second chain belts 416 and 417 can be opened away from each other to obtain a specific deployment angle, so that the cross-cut abutting body can be easily made... the engaging opening 50U of the sprocket guiding passage Get rid of. Therefore, the second and second chain belts 416 and 417 can be easily spread out from each other. Further, the connection reinforcing portion 85 is formed to increase the strength and rigidity thereof, and to increase the thickness of the side portion (the left and right (L-R) direction of the slide 4) which is not in contact with the slider 5A. On the opposite end side of the cross-cut abutting body 86, an engaging end is formed which is engaged with a portion of the opposite second life 413... by which the engaging end 87 is formed by crossing the abutting paper, and The left and right third and second chain belts 4i6, 4i. When the toothed sliding end sides are rotated in the direction in which they are unfolded, The toothed end 8 abuts the circumference of the head (4) of the second element 413, thereby promoting the rotation of the lateral (four) body 86. By this, you can be less! And the second chain belts 416, 41 are separated from each other to obtain a specific deployment angle, so that the Hengshi abutment body 86 can be easily detached from the fitting port 5〇u of the element guide passage. Therefore, ^ 146770.doc -36 - 201110902 is easy to spread the first and second chain belts 41 6 and 417 to each other. Further, in the embodiment shown in Figs. 18 and 19, the unfolding convex portion 483 and the unfolding convex portion 493 are protruded differently from each other in the front and rear directions along the opposite end edges of the chain fabric 11. Even if the unfolding convex portion 483 and the unfolding convex portion 493 are configured as described above, when the sliding member 50 is slid rearward (RS direction) from the engaging sliding end, the protruding portion 483 and the developing convex portion can be slidably contacted by the guiding post 50D. In 493, the first and second chain belts 416 and 417 are largely expanded in the left-right direction (LR direction). Thereby, the following failure can be reduced: in a state where the first and second chain belts 416 and 417 are insufficiently deployed, the collision between the guide post 50D and the first or second sprocket 412, 413 is caused, so that the sliding resistance is increased. The sense of operation deteriorates. Next, another embodiment for preliminarily holding the slider 50 on the engaging sliding end will be described using FIG. Fig. 20 is a view showing another embodiment in which the positioning convex portion 94C abutting on the guide post 50D of the slider 5 is protruded toward the opposite end edge side of the key cloth 11 as a positioning portion. The same components as those described in FIG. 5 are denoted by the same reference numerals and their description will be omitted. The first link 16 of the slide fastener 610 shown in Fig. 20 has the same configuration as that shown in Figs. The front side stopper portion 91, the slider holding portion 9.2, the unfolding convex portion 913, and the connection reinforcing portion 9.5 of the second chain belt 417 are the same as those described with reference to Figs. The embodiment shown in FIG. 20 is abutted against the rear portion of the guide post 50D in a state where the slider 50 is disposed at the sliding end of the slider instead of the insertion portion 9 4 丨丨 shown in FIG. The positioning convex portion 94C of the portion in the RS direction protrudes toward the opposite end side of the chain fabric 11 of the slider holding portion 92 in the L direction (direction toward the detaching member 80). 146770.doc -37· 201110902 As shown in FIG. 20, the positioning convex portion 94C may be protruded to the opposite end edge side of the second chain belt 617, and the slider 5' is disposed at the meshing sliding end. In this state, the positioning convex portion 94C is abutted against the rear portion of the guide post 5〇D (the portion in the RS direction), and the slider 5〇 is pre-positioned and held at the meshing sliding end' to thereby resist the cross-cutting engagement. The size Ls is controlled within a specific size range. The transverse cross-cutting engagement size can be controlled within a specific size range, and the sliding member 50 is disposed in the state of the toothed sliding end to receive a specific transverse force, toward the chain fabric U. In the case where the left and right third turns and the second chain belt 6 6 17 are rotated in the direction in which the sliding end sides are unfolded, the cross-cut abutting body 86 is engaged from the meshing opening of the element guide passage 5〇u The detachment causes the zipper 610 to be quickly separated.
