Description

Zipper slider

The present invention relates to a slider for a zipper.

The slider for a zipper generally has a slider body and a tab that is pinched by a finger when sliding the slider body. The slider body is generally formed by joining the upper and lower wings by a connecting post. A substantially Y-shaped sprocket guiding path for guiding the left and right element rows is formed between the upper wing and the lower wing in the slider body. Further, a tab mounting portion for mounting the tab is integrally formed on the upper surface of the upper blade. In many cases, the tab mounting portion is formed in a cantilever shape on the upper surface of the upper flap. In this case, the pull-tab mounting portion has a fixed end portion fixed to the upper wing plate, a free end portion disposed on a side opposite to the fixed end portion, and a mounting body portion formed from the fixed end portion to the free side Ends. Further, between the free end portion of the tab attaching portion and the upper blade, a tab insertion gap through which the mounting shaft portion of the tab can be inserted when the tab is attached to the slider body is formed. As a slider formed by attaching a tab to a slider main body provided with a tab insertion gap as described above, it is known that after the tab is attached to the tab mounting portion of the slider main body, the slider is attached. A closing member is attached between the free end of the tab mounting portion of the piece body and the upper blade to close the tab insertion gap by the closing member. Such a slider using a sealing member is disclosed in, for example, International Publication No. 2014/073111 (Patent Document 1), International Publication No. 2016/051538 (Patent Document 2), and Chinese Utility Model Publication No. 203087779 (Patent Document 3) )Wait. For example, the slider 60 described in Patent Document 1 has a slider main body 61, a pull tab 63 attached to the tab mounting portion 62 of the slider main body 61, and a closing member 64 which will slide as shown in FIG. The gap between the free end of the tab mounting portion 62 in the body 61 and the upper flap 65 is closed. In this case, in the rear end portion of the upper wing 65 of the slider main body 61, a groove-shaped member fitting portion 66 for inserting and mounting the closing member 64 is formed. Further, at the free end portion of the handle attaching portion 62, the left and right engaged portions 67 which are formed in a concave shape in order to engage the closing member 64 are disposed. By providing the member fitting portion 66 and the left and right engaged portions 67 to the slider body 61, the closing member 64 can be stably attached to a specific position of the upper blade 65. Further, the slider 70 described in Patent Document 2 has a slider main body 71, a pull tab 73 attached to the tab mounting portion 72 of the slider main body 71, and a closing member 74 which will slide as shown in FIG.

Thereby, the closing member 84 can be attached to the slider main body 81. PRIOR ART DOCUMENT Patent Document Patent Document 1: International Publication No. 2014/073111 Patent Document 2: International Publication No. 2016/051538 Patent Document 3: Chinese Utility Model Publication No. 203087779

[Problems to be Solved by the Invention] In the sliders 60 and 70 described in Patent Document 1 or Patent Document 2, it is necessary to form a closed end portion of the upper flanges 65 and 75 of the slider bodies 61 and 71 for mounting. The groove-shaped member fitting portion 66 of the members 64, 74 is inserted into the opening portion 77. In such a member fitting portion 66 or the insertion opening portion 77 provided in the slider bodies 61, 71 of the upper flaps 65, 75, the slider main body 61 may be restricted in order to appropriately secure the strength of the upper flaps 65, 75. The material of 71 and the result are that the cost reduction is hindered. Moreover, in the case of Patent Document 1 and Patent Document 2, the structure of the mold for forming the slider bodies 61 and 71 becomes complicated. For example, when a slider main body having a cantilever-shaped tab mounting portion is formed by a mold, there is a case where a mold for mold opening in the width direction of the slider is used. However, in the case of forming the mold for opening the mold in the width direction of the slider in the molding of the slider bodies 61 and 71 of Patent Documents 1 and 2, it is necessary to use a plurality of slider cores for moving in the longitudinal direction of the slider. . It is believed that the result will result in an increase in the cost of the mold or a shortened life of the mold. In the case of the slider main body 81 described in Patent Document 3, the first engaged portion 86 for engaging the closing member 84 is provided at the rear end portion of the upper blade 85 and the free end portion of the tab attaching portion 82. And the second engaged portion 87. Further, the closing member 84 is inserted between the free end portion of the tab mounting portion 82 in the slider main body 81 and the upper flap 85, and therefore, is generally formed in a small size. Further, the closing member 84 of Patent Document 3 is formed into a thin shape in which the dimension of the slider in the longitudinal direction is also small. Such a small and thin closure member 84 is less likely to be gripped when mounted to the slider body 81. Further, in the case where the closing member 84 is engaged with the slider main body 81, the closing member 84 must be held in a specific posture along the slider height direction and inserted straight toward the slider main body 81 as shown in FIG. . Therefore, the mounting work of the closing member 84 is apt to become delicate and complicated. Therefore, in the slider 80 of Patent Document 3, there is room for improvement in assembly workability. Further, since the closing member 84 of Patent Document 3 is small and thin, the portion of the closing member 84 that is engaged with the slider main body 81 is easily elastically deformed. For example, when the slider 80 of the assembled patent document 3 is slid in the direction in which the element rows are separated (rear) by pinching and pulling the tab 83, there is a pull tab 83 that is pulled rearward. The mounting shaft portion abuts against the closing member 84, and the closing member 84 is urged rearward by the mounting shaft portion of the tab 83. At this time, it is considered that the closing member 84 is easily detached from the first engaged portion 86 and the second engaged portion 87 of the slider main body 81 due to the elastic deformation. Further, in the slider 80 of Patent Document 3, the tab insertion gap formed between the free end portion of the tab attaching portion 82 of the slider main body 81 and the upper blade 85 is easily narrowed. Therefore, there is a case where the type of the pull tab that can be attached to the slider main body 81 is limited. The present invention has been made in view of the above-described problems, and a specific object thereof is to provide a slider for a slide fastener, wherein the slider main body of the slide fastener has a shape that can be used for molding a molded mold, and a closure member can be used.

In this case, it is preferable that the center protruding portion protrudes upward from the left and right inclined wall portions in a side view of the closing member. [Effects of the Invention] The slider of the present invention includes a slider main body including a tab attachment portion that is disposed in a cantilever shape on the upper blade, and a closing member that is engaged with the slider main body and is provided in the tab attachment portion The pull-tab gap between the free end and the upper wing is closed; and the pull tab is mounted and supported on the pull-tab mounting portion. In this case, the slider body has an upper wing plate, a lower wing plate disposed substantially parallel to the upper wing plate, and a front connecting column connecting the front end portion of the upper wing plate and the front end portion of the lower wing plate; And the handle mounting portion, wherein one end portion is coupled to the upper surface of the upper blade and the other end portion is disposed away from the upper blade as a free end portion; and the slider body is integrally formed integrally by molding. Further, a first engaged portion that engages the closing member is disposed on the upper body of the slider main body, and a second engaged portion that engages the closing member is disposed at a free end portion of the pull-tab mounting portion. The locking claw portion is disposed in at least one of the first engaged portion and the second engaged portion, and the locking claw portion locks the closing member to restrict the movement of the closing member rearward. The first engaged portion provided on the upper blade has a member holding portion that is erected on the upper blade in the longitudinal direction of the slider and has a T-shaped cross section perpendicular to the longitudinal direction of the slider. The member holding portion has a holding post portion that rises from the upper blade and a left and right projecting piece that protrudes from the upper end portion of the holding post portion in the width direction of the slider. Further, the rear end position of the left and right projecting piece portions in the longitudinal direction of the slider is disposed further forward than the end position of the slider at the free end portion of the pull tab mounting portion. The closure member of the present invention has a first engagement portion that engages with the first engaged portion of the upper blade, and a second engagement portion that engages with the second engaged portion that is disposed on the handle attachment portion. And a locking claw portion that is locked to the locking holding portion. Further, the first engaging portion of the closing member has left and right insertion portions that are inserted between the right and left projecting piece portions of the member holding portion and the upper blade. In the case of the slider of the present invention, the groove-shaped member fitting portion 66 (see FIG. 16) of the above-described Patent Document 1 or the insertion opening portion of Patent Document 2 is not formed on the flap main body. 77 (refer to Fig. 17), therefore, it is easy to stably ensure the strength of the upper wing. Further, the first engaged portion disposed on the upper surface of the slider main body and the second engaged portion disposed at the free end portion can be formed into a mold that can be opened by the mold in the width direction of the slider. Shape (relative to the shape of the undercut of the mold). Therefore, for example, the structure of the mold can be simplified as compared with the case of the slider bodies 61 and 71 of Patent Document 1 and Patent Document 2, and therefore, it is expected to reduce the cost of the mold or extend the life of the mold. Further, according to the slider of the present invention, the rear end position of the left and right projecting piece portions of the first engaged portion is arranged at the rear end position of the slider at the free end portion of the pull tab mounting portion. The position is more forward. Therefore, it is easy to ensure that the size (height size) of the slider insertion gap formed between the free end portion of the slider mounting portion of the slider main body and the upper blade is larger in the height direction of the slider, and therefore, When the tab or the closing member is attached to the slider body, the mounting shaft portion or the closing member of the tab can be easily inserted between the upper blade and the free end of the tab mounting portion. Therefore, the assembly workability of the slider can be improved. Further, the type of the pull-tab that can be attached can be increased as compared with, for example, the slider main body 81 of the above-described Patent Document 3 in which the insertion gap of the tab is narrow. In particular, in this case, the front end position of the member holding portion is disposed further forward than the front end position of the free end portion of the pull tab mounting portion in the longitudinal direction of the slider. Thereby, the member holding portion can hold the closing member more stably, thereby stably maintaining the state in which the closing member is engaged with the slider body. Further, in the longitudinal direction of the slider, the rear end positions of the left and right projecting piece portions are disposed further forward than the intermediate position between the front end position and the rear end position of the free end portion. Thereby, it is easy to ensure that the height of the tab insertion gap is larger, so that the mounting shaft portion and the closing member of the tab can be more easily inserted between the upper flap and the free end of the tab mounting portion. In the slider according to the present invention, the first engaged portion disposed on the upper blade has a member abutting portion that abuts the left and right insertion portions of the closing member, and a member guiding portion that is arranged in a protruding shape The upper wing plate extends from the member holding portion toward the rear in the longitudinal direction of the slider. In this case, the member abutting portion is formed at a front end portion of the first engaged portion so that the dimension in the width direction of the slider is larger than that of the holding column portion. Further, the closing member has a receiving groove portion continuously formed from a gap formed between the left and right insertion portions, and the member guiding portion of the first engaged portion can be accommodated in the receiving groove portion. When the first engaged portion and the closing member of the upper blade are formed as described above, when the closing member is attached to the slider body, the closing member can be guided along the member guiding portion of the first engaged portion. The closing member is engaged with the first engaged portion. Therefore, the assembly workability of the slider can be further improved. Further, since the first engagement portion is provided with the member abutting portion, the closing member can be stably engaged with the specific position of the slider main body, and the engagement state of the closing member can be made more stable. In this case, the dimension of the member guide portion of the first engaged portion from the upper blade in the height direction of the slider is set to be slippery from the upper flap of the member holding portion of the first engaged portion. The height of the piece is smaller. Thereby, the guiding of the closing member by the member guiding portion can be stably performed. Further, even if the member guiding portion is protruded from the upper surface of the upper blade, it is easy to appropriately ensure the height dimension of the tab insertion gap. Therefore, it is possible to suppress the ease of insertion when the mounting shaft portion or the closing member of the tab is inserted due to the formation of the member guiding portion. Further, in the longitudinal direction of the slider, the position of the rear end of the member guiding portion in the first engaged portion is disposed at the same position as the rear end of the free end portion of the tab mounting portion, or at the rear end position of the free end portion. More rearward. Thereby, when the closing member is attached to the slider main body, the closing member can be guided from the position on the rear side, so that the closing member can be attached more smoothly. Moreover, it is preferable that the member guide portion and the rear end position of the free end portion of the tab attachment portion are the same, thereby preventing the appearance of the slider (appearance quality) or the deterioration of the skin feel due to the formation of the member guide portion. Further, in the slider of the present invention, the locking restricting portion that locks the closing member is provided in the second engaged portion of the free end portion of the handle attaching portion by a pair of right and left. Further, the closing member has a base portion that is placed on the upper wing plate, a pair of left and right vertical wall portions that are erected on the base portion, and a central abutment portion that is erected on the base portion and disposed on the left and right vertical walls. The inter-parts; and the right and left locking claw portions are disposed as the second engaging portions at the upper end portions of the left and right vertical wall portions. The left and right locking claw portions project from the inner wall surface of the left and right vertical wall portions toward the inner side in the width direction of the slider. The closing member having such a configuration can be formed into a shape (a shape that is not undercut with respect to the mold) that can be formed by a mold that is opened in the longitudinal direction of the slider. Moreover, such a closing member has a shape that is easily grasped by a finger or the like, and therefore can be smoothly inserted between the upper end of the slider main body and the free end portion of the tab mounting portion, and can be securely engaged and mounted. In the slider body. Further, when the slider of the present invention is slid in the separation direction (rear direction) of the element rows, for example, when the slider is pulled, the attachment shaft portion of the pull tab abuts against the closing member, and the closing member is rearward. When pushed, the engagement state of the closing member with respect to the slider body can be stably maintained. In this case, the second engaged portion disposed in the pull-tab mounting portion has a spacer portion that is disposed at a central portion of the free end portion of the pull-tab mounting portion in the width direction of the slider along the longitudinal direction of the slider; The left and right front side bulging portions are disposed at the front end portion of the partition portion and bulged from the partition portion in the slider width direction, and the left and right locking restricting portions are disposed at the rear end portion of the partition portion. Further, between the front side bulging portion and the rear end side locking claw portion of the second engaged portion, the left and right accommodation concave portions for accommodating the locking claw portions of the closing member are provided. Thereby, when the closing member is inserted and attached between the upper end of the slider main body and the free end of the tab mounting portion, the closing member can be more firmly mounted at a specific position. Further, by this, it is possible to more effectively prevent the closing member from being detached from the slider main body and falling off. Further, the closing member of the present invention has: left and right inclined wall portions extending forward from the left and right vertical wall portions and decreasing in size in the height direction of the slider; and a central protruding portion from the center abutment portion Prominent in front. Further, the gap between the accommodating groove portion recessed in the lower end portion of the base portion of the closing member and the insertion portion provided between the left and right insertion portions is continuously continuous in the front-rear direction. In this case, the inner wall surfaces of the left and right inclined wall portions in the closing member are continuously formed from the inner wall surfaces of the right and left vertical wall portions. Further, the central projection in the closing member has a flat lower surface that is in contact with the upper surface of the member holding portion, and an inclined upper surface that is inclined downward toward the front. Such a closing member has a shape that is easier to grip with a finger or the like, and therefore, the closing member can be smoothly attached to the slider main body and firmly and stably engaged. Further, when the slider of the present invention is slid in the direction in which the element rows are separated (rearward), for example, when the tab is pulled, even if the mounting shaft portion of the tab abuts against the closing member, the closing member can be used. The inclined upper surface of the left and right inclined wall portions or the central protruding portion allows the mounting shaft portion of the pull tab to easily move upward. Thereby, the closing member is less likely to be pressed rearward by the mounting shaft portion of the pull tab, and the closing member can be effectively prevented from being deviated from the slider main body and coming off. In particular, in this case, the central projection of the closure member protrudes upward from the left and right inclined wall portions of the closure member in a side view of the closure member. Thereby, when the attachment shaft portion of the pull tab moves rearward and comes into contact with the closing member, the attachment shaft portion of the pull tab can be efficiently moved upward toward the free end portion of the tab attachment portion. As a result, the tab mounting portion of the slider body (especially the free end portion of the tab mounting portion) can be used to support the mounting shaft portion of the pull tab, thereby making it easier for the closing member to be pressed by the mounting shaft portion of the pull tab. .

On the upper wing 11, For example, the engaged portion formed by recessing the upper surface of the upper blade from the upper surface of the upper blade is not provided, Or, as disclosed in Patent Document 2, it is formed in an insertion opening portion of the upper blade. also, The upper surface of the upper blade 11 is provided with a tab mounting portion 15 Keyhole forming portion 16, And the part of the first engaged portion 20, Formed as a smooth plane or a slightly curved curved surface.  At the rear end of the upper wing 11, The first engaged portion 20 that engages the lower end portion of the closing member 40 is formed to protrude upward from the upper surface of the upper blade 11. The first engaged portion 20 has a shape that is bilaterally symmetrical with respect to the center position in the width direction of the slider. also, The first engaged portion 20 is formed such that The maximum value of the dimension of the first engaged portion 20 in the width direction of the slider (hereinafter abbreviated as the width dimension) is, for example, larger than the maximum width of the fixed end portion 15a of the handle attaching portion 15 as shown in FIG. small, Further, the maximum value of the width dimension in the front connecting post 13 is smaller.  The first engaged portion 20 of the present embodiment has: Member holding portion 21, It is disposed along the length of the slider on the upper surface of the upper wing 11 and holds the closure member 40; Member abutment portion 24, It is disposed at a front end of the first engaged portion 20 and abuts the front end of the closing member 40; And member guiding portion 25, The self-member holding portion 21 extends rearward in the longitudinal direction of the slider.  The member holding portion 21 of the first engaged portion 20 has: Holding the column portion 22, It stands up straight from the upper wing 11 toward the top; And the left and right protruding pieces 23, The upper end of the self-retaining column portion 22 protrudes in the width direction of the slider; Further, the cross section of the member holding portion 21 orthogonal to the longitudinal direction of the slider has a T-shape. In this case, The cross section of the member holding portion 21 orthogonal to the longitudinal direction of the slider has a fixed shape throughout the longitudinal direction of the slider of the member holding portion 21.  On the left and right sides of the holding column portion 22, The accommodating space portion sandwiched between the upper surface of the upper blade 11 and the lower surface of the projecting piece 23 is formed. The left and right insertion portions 42 of the closing member 40 are housed and held in the left and right accommodation space portions of the first engaged portion 20.  In the member holding portion 21 of the present embodiment, Under the side view of the slider body 10 (Fig. 6), The front end position of the member holding portion 21 is disposed at the front end of the lower end portion 15b of the pull tab mounting portion 15 in the longitudinal direction of the slider (in particular, The position L1 of the front end of the second engaged portion 30 of the free end portion 15b is further forward. also, The rear end position of the member holding portion 21 (in particular, The rear end position of the right and left projecting piece portions 23 in the member holding portion 21 is disposed further forward than the position L2 of the rear end of the free end portion 15b of the pull-tab mounting portion 15 in the longitudinal direction of the slider. Preferably, it is disposed further forward than the position L3 between the front end position L1 and the rear end position L2 in the free end portion 15b.  By arranging the front end position of the member holding portion 21 as described above, When the closing member 40 is inserted from the rear side of the slider body 10 to the tab insertion gap 19 formed between the upper blade 11 and the free end portion 15b of the tab mounting portion 15 to be engaged with the slider body 10 , The right and left insertion portions 42 of the closing member 40 can be firmly held by the member holding portion 21. therefore, It is possible to prevent the posture of the closing member 40 from being tilted in such a manner that the left and right insertion portions 42 are lifted from the upper surface of the upper blade 11. Thereby, the closing member 40 can be stably attached to the slider main body 10 in a specific posture. and then, The state in which the closing member 40 is engaged with the slider main body 10 can be stably maintained.  also, The position of the rear end of the member holding portion 21 is disposed further forward than the intermediate position L3. The area where the distance between the first engaged portion 20 and the free end portion 15b of the handle attaching portion 15 in the slider height direction is restricted by the member holding portion 21 can be made small. therefore, Compared to, for example, the case where the member holding portion 21 is continuously formed to the engagement port side edge of the upper blade 11, The height dimension of the tab insertion gap 19 into which the mounting shaft portion 52 of the pull tab 50 or the closing member 40 is inserted can be largely ensured in a wider range of the length direction of the slider. the result, The mounting shaft portion 52 or the closing member 40 of the pull tab 50 can be easily and smoothly inserted between the upper blade 11 and the free end portion 15b of the tab mounting portion 15.  also, In the member holding portion 21 of the present embodiment, The height dimension of the holding column portion 22 from the upper surface of the upper blade 11 is set corresponding to the height dimension of the insertion portion 42 of the closing member 40. in particular, The above-described height dimension of the holding column portion 22 is set to be larger than the height dimension of the insertion portion 42 of the closing member 40. also, As shown in Figure 7, The dimension (width dimension) of the retaining post portion 22 in the width direction of the slider is smaller than the width dimension of the tab mounting portion 15. also, The width dimension of the holding column portion 22 is set to be equal to or slightly smaller than the width dimension of the following partition portion 31 of the second engaged portion 30 disposed at the free end portion 15b of the handle attaching portion 15 size.  Each of the left and right projecting piece portions 23 in the member holding portion 21 is set to have a height from the upper surface of the upper blade 11 to the upper surface of the projecting piece 23 to be maintained from the upper surface of the upper blade 11 to the upper surface. The upper end of the column portion 22 is formed to have the same height dimension. also, Each of the projecting pieces 23 is formed such that the height dimension between the upper surface and the lower surface of the projecting piece portion 23 is smaller than the height dimension of the holding column portion 22 from the upper surface of the upper wing plate 11. and then, The width of the right end edge of the projecting piece 23 from the left end edge to the right side of the projecting piece 23 on the left side is smaller than the width dimension of the handle mounting portion 15. also, The width from the left end edge of the left projecting piece 23 to the right end edge of the right projecting piece 23 is set to be larger than the width of the holding column portion 22. In this case, The width dimension of each of the left and right projecting piece portions 23 is set to be the same as the width dimension of the holding post portion 22 or slightly larger than the width dimension of the holding post portion 22. Here, E.g, The width dimension of the projecting piece 23 on the left side refers to the dimension in the width direction of the slider from the left end edge of the projecting piece 23 on the left side to the boundary position of the projecting piece 23 and the holding post 22 on the left side.  The member abutting portion 24 of the first engaged portion 20 is formed at a front end of the first engaged portion 20 and connected to the front end of the member holding portion 21 . The member abutting portion 24 is disposed to rise from the upper surface of the upper blade 11. also, The height dimension of the member abutting portion 24 from the upper surface of the upper blade 11 is set to be the height dimension from the upper surface of the upper blade 11 in the holding column portion 22 of the member holding portion 21, And the height from the upper surface of the upper blade 11 to the upper surface of the left and right protruding piece portions 23 is the same size.  The width of the member abutting portion 24 is set to be larger than the width of the holding column portion 22 of the member holding portion 21, It is preferable to set the same size as the width of the side edge of the projecting piece portion 23 from the side edge of the left projecting piece 23 to the right side of the projecting piece portion 23.  and then, The front surface of the member abutting portion 24 of the present embodiment is viewed from the side of the slider body 10 (Fig. 6). An inclined surface that is inclined from the upper surface of the upper blade 11 toward the rear direction is formed. also, as shown in picture 2, The inclination angle of the front surface of the member abutting portion 24 with respect to the upper surface of the upper blade 11 is set to be smaller than the inclination angle of the inclined upper surface of the lower central member 47 of the closing member 40 with respect to the upper surface of the upper blade 11 Bigger.  The front surface of the member abutting portion 24 is formed obliquely as described above, E.g, When the slider 50 of the slider 1 is pulled and the slider 1 is slid rearward (the direction in which the element rows are separated), The mounting shaft portion 52 of the pull tab 50 can be moved upward along the front surface of the member abutting portion 24 as shown by the imaginary line (two-point chain line) in FIG. 2 . Thereby, the mounting shaft portion 52 of the tab 50 can be easily guided to the free end portion 15b of the tab mounting portion 15. With this, The closing member 40 that is engaged with the slider body 10 is less likely to be pushed rearward by the mounting shaft portion 52 of the tab 50. the result, The failure of the closing member 40 to be deflected from the slider body 10 and falling off is less likely to occur.  The member guide portion 25 of the first engaged portion 20 is a pad that is protruded from the upper surface of the upper blade 11 and protrudes straight from the member holding portion 21 toward the rear in the longitudinal direction of the slider. Formed by the Ministry. The member guiding portion 25 is not provided with the left and right protruding piece portions 23 such as the member holding portion 21, Further, the holding column portion 22 of the member holding portion 21 is continuously formed rearward. The width of the member guiding portion 25 is set to be the same as the width dimension of the holding column portion 22 of the member holding portion 21. especially, The member guiding portion 25 of the present embodiment is formed by having a fixed width dimension from the upper surface of the upper blade 11 to a specific height position. also, The upper portion of the member guide portion 25 at a more specific height position is formed by gradually decreasing the width dimension.  The upper end position of the member guide portion 25 of the present embodiment is disposed at a lower position with respect to the upper end position of the member holding portion 21 as shown in Fig. 6 . In this case, The height of the member guide portion 25 from the upper surface of the upper blade 11 is set to be smaller than the height of the member holding portion 21 from the upper surface of the upper blade 11. If specifically explained, The height dimension of the member guide portion 25 from the upper surface of the upper blade 11 is set to be 20% or more and 80% or less of the height dimension of the member holding portion 21 from the upper surface of the upper blade 11. It is preferably set to 40% or more and 60% or less.  The height dimension of the member guiding portion 25 is 20% or more of the height dimension of the member holding portion 21, When the closing member 40 is inserted from the rear side of the slider main body 10 to the tab insertion gap 19, The member guiding portion 25 easily enters between the left and right insertion portions 42 of the closing member 40, Thereby, the closing member 40 can be smoothly guided by the member guiding portion 25. also, The height dimension of the member guiding portion 25 is 80% or less of the height dimension of the member holding portion 21, It is ensured that the interval between the free end portion 15b of the tab mounting portion 15 and the member guiding portion 25 is wide. Therefore, the attachment shaft portion 52 of the pull tab 50 or the closing member 40 can be easily inserted between the first engaged portion 20 and the free end portion 15b of the handle attaching portion 15.  also, In this embodiment, Under the side view of the slider body 10 (Fig. 6), The rear end position of the member guiding portion 25 is disposed at the same position as the rear end position L2 of the free end portion 15b of the handle attaching portion 15 in the longitudinal direction of the slider. With this, When the closing member 40 is attached to the slider body 10, The closing member 40 can be smoothly guided from the position on the rear side. also, E.g, As shown in Figure 1, The position of the end face after the member guiding portion 25 can be made, The position of the end face behind the closure member 40, And the positions of the end faces after the tab mounting portion 15 are aligned on substantially the same plane, therefore, It is possible to suppress the appearance (appearance quality) of the slider 1 or the deterioration of the skin feel due to the formation of the member guiding portion 25.  Furthermore, In another embodiment, Viewed from the side of the slider body 10, The rear end position of the member guiding portion 25 may be formed on the rear end side of the rear end position L2 of the free end portion 15b of the pull tab mounting portion 15 in the longitudinal direction of the slider. In this case, The closing member 40 can be easily inserted into the member guiding portion 25.  The pull tab mounting portion 15 of the slider body 10 has: Fixed end 15a, It is disposed at the front end of the pull tab mounting portion 15, And fixed to the upper wing 11; Mounting the body portion 15c, One side of the self-fixing end portion 15a is bent in a substantially C shape. One extends to the rear, And inserted into the opening window portion 53 of the mounting shaft portion 52 of the pull tab 50; And the free end 15b, The end portion of the main body portion 15c is bent downward toward the upper blade 11 so as to be bent downward. And arranged away from the upper wing plate 11.  The fixed end portion 15a of the pull-tab mounting portion 15 is formed by rising from the upper surface of the upper blade 11. In other words, It is formed by being coupled to the upper surface of the upper blade 11. The width of the fixed end portion 15a is set to be larger than the width of the front connecting post 13. The mounting body portion 15c of the tab mounting portion 15 is continuously formed from the fixed end portion 15a. And it extends towards the rear. The mounting main body portion 15c of the present embodiment is formed such that its width dimension is slightly decreased toward the rear.  The free end portion 15b of the pull-tab mounting portion 15 is continuously formed downward from the mounting body portion 15c. The end face (lower end face) of the free end portion 15b is, for example, as shown in FIG. Opposes the upper surface of the upper wing 11. The free end portion 15b has a shape that is bilaterally symmetrical with respect to the center position in the width direction of the slider.  also, The free end portion 15b of the present embodiment has a base end portion 35 coupled to the attachment main body portion 15c, And the second engaged portion 30 that is formed to protrude downward from the proximal end portion 35 and that engages the upper end portion of the closing member 40. The base end portion 35 of the free end portion 15b has left and right outer sides continuously formed from the mounting body portion 15c. Further, the width dimension between the left and right outer side faces of the base end portion 35 is set to be larger than the width dimension of the front connecting post 13.  The second engaged portion 30 provided in the free end portion 15b has as shown in FIG. 3 or FIG. 8 and the like: Spacer 31, It is disposed at a central portion of the free end portion 15b in the width direction of the slider; Left and right front side bulging portion 32, The same is disposed at the front end of the partition portion 31; And the left and right locking restriction portions 33, They are disposed at the rear end of the partition portion 31.  also, In the second engaged portion 30, As shown in Figure 8, A housing recess 34 for accommodating the left and right locking claw portions 44 of the closing member 40 is formed between the left and right front side bulging portions 32 and the left and right locking restricting portions 33. In this case, The receiving recess 34 is viewed in a cross section orthogonal to the height direction of the slider (Fig. 3). The shape is formed to correspond to the shape of the locking claw portion 44 of the closing member 40.  The partition portion 31 of the second engaged portion 30 extends downward from the base end portion 35 of the free end portion 15b. And arranged linearly along the longitudinal direction of the slider. The center portion of the spacer 31 in the longitudinal direction of the slider is disposed between the front side bulging portion 32 and the locking restricting portion 33. And exposed to the outside. therefore, When the locking claw portion 44 of the closing member 40 is received in the housing recessed portion 34 of the second engaged portion 30 and the closing member 40 is locked to the locking restricting portion 33 of the second engaged portion 30, The central portion of the partition portion 31 is sandwiched by the right and left locking claw portions 44 of the closing member 40.

The sliders 1 of the two sets are slidably attached to the left and right chain rows of the slide fastener so that the end portions on the inlet side face each other. With this, A zipper that can connect the two sliders 1 by one lock member such as a padlock is formed.  In this zipper, By holding the two sliders 1 in a positional relationship in which the respective lock hole forming portions 16 abut against the tab mounting portions 15 of the sliders 1 on the object side, the respective keyhole forming portions 16 are mutually different from the slider width. Overlapping in direction, Thereby, the circular keyholes 16a of the keyhole forming portions 16 of the two sliders 1 communicate with each other.  therefore, By inserting the lock pin of the lock member into the interlocking hole 16a of the two sliders 1, The relative positional relationship of the two sliders 1 can be fixed. With this, The zipper can be prevented from being opened by the sliding operation of the slider 1. Furthermore, In the present invention, The slider body 16 may be formed without providing the keyhole forming portion 16 as described above.  As shown in FIGS. 9 to 13 , the closing member 40 attached to the slider body 10 as described above is formed to have a bilaterally symmetrical shape with respect to the center position in the width direction of the slider.  The closure member 40 has: Base bottom 41; a pair of left and right insertion portions 42, It branches from the base portion 41 and extends forward; a pair of left and right vertical wall portions 43, They are erected on the left and right side edge portions of the base portion 41; Left and right locking claws 44, They are disposed at the upper ends of the left and right vertical wall portions 43; a pair of left and right inclined wall portions 45, The front wall portion 43 extends forward from the left and right vertical wall portions 43; Central abutment 46, It is erected in a central portion of the base portion 41 in the width direction of the slider; And a central protrusion 47, It protrudes forward from the center base portion 46. Furthermore, In the closing member 40 of the present embodiment, Each ridge portion of the closing member 40 is formed in a curved surface shape as chamfered.  The base portion 41 of the closure member 40 is formed as a base of the closure member 40 with an appropriate height dimension. The left and right sides of the member guiding portion 25 of the first engaged portion 20 are placed on the upper surface of the upper blade 11. therefore, The lower end surface of the base portion 41 is a surface that is in contact with the upper surface of the upper blade 11. The lower end surface of the base portion 41 is formed continuously with the lower end surface of the left and right insertion portions 42. A single plane is formed by the lower end surface of the base portion 41 and the lower end surface of the left and right insertion portions 42.  At the lower end of the base portion 41, The accommodating groove portion 48 formed continuously from the gap between the right and left insertion portions 42 toward the rear is formed. The receiving groove portion 48 is recessed in a groove shape from the lower end surface of the base portion 41 to the lower end portion of the base portion 41. And formed along the length of the slider. which is, The gap between the accommodating groove portion 48 and the insertion portion 42 provided on the right and left is continuously formed in the front-rear direction along the longitudinal direction of the slider. In the receiving groove portion 48, When the closing member 40 is engaged and attached to the slider main body 10, the member guiding portion 25 which is formed in a protruding shape on the upper surface of the upper blade 11 is engaged.  The left and right insertion portions 42 of the closing member 40 are branched as a first engagement portion that engages with the first engaged portion 20 of the slider body 10, and extends forward from the front end portion of the base portion 41. The height of each of the right and left insertion portions 42 is set to be sized to be inserted between the upper blade 11 and the projecting piece portion 23 of the member holding portion 21 in the slider body 10. especially, The insertion portion 42 of the present embodiment has a shape in which the height dimension of the insertion portion 42 is gradually decreased toward the front. also, The right and left insertion portions 42 are in the longitudinal direction of the slider so that the front end portion of the insertion portion 42 abuts exactly the first engaged portion 20 of the slider body 10 when the closing member 40 is engaged and attached to the slider body 10 . The length of the member abutting portion 24 is formed.  and then, Between the left and right insertion portions 42 of the closing member 40, A gap is formed in which the holding column portion 22 of the member holding portion 21 can be inserted. When the closing member 40 is attached to the slider body 10, The holding column portion 22 of the member holding portion 21 is inserted into the gap between the right and left insertion portions 42 of the closing member 40. at this time, The inner edge portions of the right and left insertion portions 42 are in contact with the left and right side wall surfaces of the holding column portion 22, Further, the member guiding portion 25 of the first engaged portion 20 is inserted into the receiving groove portion 48 of the base portion 41. With this, The movement of the closing member 40 attached to the slider body 10 in the width direction of the slider is restricted.  The left and right vertical wall portions 43 of the closing member 40 have a specific width dimension. The left and right side edge portions of the base portion 41 extend upward. The right and left vertical wall portions 43 are formed to be elastically deformable so that the upper end portion of the vertical wall portion 43 swings in the slider width direction. also, The outer wall surface and the rear end surface of the right and left vertical wall portions 43 on the outer side in the width direction of the slider are continuously formed from the left and right side surfaces and the rear end surface of the base portion 41, respectively.  The upper end surface of the right and left vertical wall portions 43 is in a state where the closing member 40 is attached to the slider main body 10 as shown in FIG. 2 . It is in contact with the base end portion 35 of the free end portion 15b of the handle mounting portion 15. therefore, In the closing member 40 of the present embodiment, When the closing member 40 is attached to the slider body 10, Not only the left and right insertion portions 42 of the closing member 40 are inserted between the upper flap 11 of the slider main body 10 and the protruding piece portion 23 of the member holding portion 21, Further, the lower end surface of the base portion 41 is in contact with the upper surface of the upper blade 11 and the upper end surface of the vertical wall portion 43 is in contact with the free end portion 15b of the tab mounting portion 15, Thereby, the movement of the shutter member 40 in the height direction of the slider can be stably restricted. With this, The closing member 40 is stably mounted with respect to the slider main body 10 at a specific position in the height direction of the slider.  In the closing member 40 of the present embodiment, The interval between the outer wall surfaces of the right and left vertical wall portions 43 in the width direction of the slider is set to be the base end portion 35 of the free end portion 15b of the handle mounting portion 15 of the slider main body 10, for example, as shown in Fig. 4 . The width between the outer sides is approximately the same size. Or set to be slightly smaller than the interval. also, The interval between the inner wall surfaces of the left and right vertical wall portions 43 in the width direction of the slider is set to be larger than the left end edge of the projecting portion 21 of the slider main body 21 from the left end edge of the projecting piece 23 on the right side to the right side. The width of the right end edge of the portion 23 is larger.  The left and right locking claw portions 44 of the closing member 40 serve as the second engaging portion of the second engaged portion 30 of the slider main body 10 at the upper end portion of the left and right vertical wall portions 43 and the front end portion from the vertical wall. The inner wall surface of the portion 43 protrudes toward the inner side in the width direction of the slider. The right and left locking claw portions 44 have locking surfaces that face in a direction orthogonal to the inner wall surface of the vertical wall portion 43. The locking surfaces of the right and left locking claw portions 44 are in surface contact with the locking restricting portions 33 of the second engaged portion 30 of the slider body 10 as shown in FIG. With this, The closing member 40 is locked by the second engaged portion 30 of the slider body 10, It is maintained in such a way that it cannot move backwards.  The front end portions of the left and right locking claw portions 44 are gradually decreased toward the front in the width dimension thereof. The cross section orthogonal to the height direction of the slider has a substantially triangular shape. The inner wall surface of the front end portion of the left and right locking claw portions 44 is disposed to be inclined forward with respect to the longitudinal direction of the slider, and is disposed to be inclined outward.  Since the front end portion of the locking claw portion 44 is formed in the shape as described above, Therefore, when the closing member 40 is inserted from the slider main body 10 to the tab insertion gap 19, The front end portion of the locking claw portion 44 is in sliding contact with the locking restricting portion 33 of the second engaged portion 30, The elastic deformation of the vertical wall portion 43 can be effectively promoted by opening the left and right vertical wall portions 43 of the closing member 40 outward.  If more specific, Then when the closure member 40 is inserted, The substantially triangular shape front end portion of the locking claw portion 44 is in sliding contact with the rear side inclined surface of the locking restriction portion 33 of the second engaged portion 30 of the slider main body 10, and is in sliding contact. With this, The left and right vertical wall portions 43 of the closing member 40 can be elastically deformed so as to be expanded toward the outside. With this, The right and left locking claw portions 44 of the closing member 40 can be smoothly passed over the locking restricting portions 33 of the second engaged portion 30, and are locked to the left and right locking restricting portions 33 as shown in FIG. which is, The accommodation recessed portion 34 of the second engaged portion 30 is received and the locking surface of the left and right locking claw portions 44 abuts against the front side locking surface of the locking restriction portion 33. and then, When the right and left locking claw portions 44 of the closing member 40 are locked to the left and right locking restricting portions 33 of the second engaged portion 30, The substantially triangular shape front end portion of the locking claw portion 44 can be brought into contact with the front side bulging portion 32 of the second engaged portion 30. With this, The closure member 40 can be stably stopped at a specific position.  and then, In the closing member 40 of the present embodiment, When the closing member 40 is attached to the slider body 10, The left and right locking claw portions 44 are housed in the housing recessed portion 34 of the second engaged portion 30, Further, the front end portion of the right and left insertion portions 42 of the closing member 40 is in contact with the member abutting portion 24 of the first engaged portion 20 of the slider main body 10. With this, The movement of the slider member in the longitudinal direction of the slider is restricted. the result, The closure member 40 cannot be completely fixed relative to the slider body 10, Therefore, it is stably mounted at a specific position in the longitudinal direction of the slider.  The left and right inclined wall portions 45 of the closing member 40 are continuously formed toward the front from the left and right vertical wall portions 43. which is, The inner wall surface and the outer wall surface of the inclined wall portion 45 are continuously formed from the inner wall surface and the outer wall surface of the right and left vertical wall portions 43, respectively, so as to form a flat surface. also, The left and right inclined wall portions 45 are respectively erected on the outer side edge portions of the left and right insertion portions 42. and then, The inclined wall portion 45 is formed such that the upper surface of the inclined wall portion 45 is inclined downward toward the front so that the height dimension is gradually decreased toward the front. also, The front edge of the left and right inclined wall portions 45 is disposed at the same position as the front edge of the left and right insertion portions 42 in the longitudinal direction of the slider.  By providing such a left and right inclined wall portion 45, The size of the sliding member in the longitudinal direction of the closing member 40 can be increased. On the other hand, the closing member 40 is formed into a shape that is easily pinched from the right and left with a finger or the like. also, By the left and right inclined wall portions 45, The member holding portion 21 disposed on the first engaged portion 20 of the slider body 10 can be covered from the left and right outer sides so as not to be easily observed from the outside. therefore, The appearance quality of the slider 1 can be improved.  The central abutment portion 46 of the closing member 40 is erected upward from the base portion 41, Further, it is disposed by being sandwiched by the left and right vertical wall portions 43. also, The outer side surface of the central abutment portion 46 is spaced apart from the left and right vertical wall portions 43, Further, a gap that allows the elastic deformation of the vertical wall portion 43 is formed. The height position of the upper surface of the center abutment portion 46 is set to be lower than the height of the lower surface of the left and right locking claw portions 44, for example, as shown in FIG. also, The upper surface of the center abutment portion 46 is formed into a concave surface shape in which the central portion in the width direction of the slider is recessed in the longitudinal direction of the slider.  By providing such a central abutment portion 46, The central protrusion 47 of the closing member 40 can be stably formed, And the strength of the central protrusion 47 can be appropriately ensured. also, With the central abutment 46, For example, even if the pull-tab mounting portion 15 of the slider main body 10 is subjected to a force such as being pressed downward, The free end portion 15b of the tab mounting portion 15 can also be supported by the central abutment portion 46 of the closure member 40. therefore, The deformation of the tab mounting portion 15 can be suppressed. and then, By being provided with a central abutment portion 46, It is also possible to prevent foreign matter from entering and being sandwiched between the left and right vertical wall portions 43 of the closing member 40.  The central projection 47 of the closing member 40 extends forward from the central abutment portion 46. In this case, The front edge of the center projecting portion 47 is disposed at the same position as the front end edge of the right and left insertion portions 42 and the front end edge of the left and right inclined wall portions 45 as shown in FIG. 12 in the longitudinal direction of the slider. The central protruding portion 47 of this embodiment has: Base end, It has a fixed height dimension; And the end, It gradually reduces the height dimension toward the front.  In this case, The lower end surface of the base end portion of the central projection 47 and the lower end surface of the distal end portion are formed as a single plane orthogonal to the height direction of the slider. also, The lower end surface of the distal end portion of the central protruding portion 47 is formed to be in contact with the upper surface of the member holding portion 21 of the first engaged portion 20 when the closing member 40 is attached to the slider main body 10. With this, As shown in Figure 4, The right and left insertion portions 42 and the center protruding portion 47 of the closing member 40 can be supported by sandwiching the left and right protruding piece portions 23 of the first engaged portion 20 of the slider body 10.  The upper surface of the base end portion of the central projecting portion 47 is formed in the same manner as the upper surface of the center base portion 46 in a concave shape in which the central portion in the width direction of the slider is recessed in the longitudinal direction of the slider.  The upper surface of the distal end portion of the central projection 47 is formed as an inclined upper surface that is inclined downward toward the front. In this case, The inclination angle of the inclined upper surface of the central projection 47 with respect to the upper surface of the upper blade 11 is set to be the same as the inclination angle of the upper surface of the inclined wall portion 45 with respect to the upper surface of the upper blade 11, Further, it is set to be smaller than the inclination angle of the front surface of the member abutting portion 24 of the first engaged portion 20 with respect to the upper surface of the upper blade 11. and then, In this embodiment, Under the side view of the closure member 40 (Fig. 13), The center protruding portion 47 is disposed to protrude upward from the left and right inclined wall portions 45.  By forming the inclined upper surface of the central projection 47 as described above, E.g, When the pull tab 50 is pulled rearward so that the mounting shaft portion 52 touches the closing member 40, The mounting shaft portion 52 of the pull tab 50 can be directed upward along the inclined upper surface of the central projection portion 47 toward the free end portion 15b of the tab mounting portion 15. It is brought into contact with the free end portion 15b (refer to Fig. 2). With this, The mounting shaft portion 52 of the pull tab 50 can be supported by the free end portion 15b of the pull tab mounting portion 15, the result, In the direction in which the pull tab 50 is strongly pulled, The mounting shaft portion 52 becomes less likely to come into contact with the closing member 40, Further, the closing member 40 can be more easily pushed back by the mounting shaft portion 52 of the tab 50.  Secondly, Using the slider body 10 described above, Pull tab 50, The sealing member 40 and the method of assembling the slider 1 of this embodiment are demonstrated.  First of all, The work is performed by attaching the pull tab 50 to the handle mounting portion 15 of the slider main body 10. in particular, The mounting shaft portion 52 of the pull tab 50 is inserted from the rear side of the slider main body 10 to the tab insertion gap 19 disposed between the upper surface of the upper blade 11 and the free end portion 15b of the tab attaching portion 15.  at this time, The first engaged portion 20 is provided on the upper blade 11 as described above. The rear end position of the member holding portion 21 of the first engaged portion 20 is disposed further forward than the intermediate position L3 between the front end position L1 and the rear end position L2 of the free end portion 15b. also, The member guide portion 25 of the first engaged portion 20 has a height dimension smaller than that of the member holding portion 21.  With this, That is, the first engaged portion 20 is protruded from the upper surface of the upper blade 11, and The height dimension of the space between the free end portion 15b of the tab attaching portion 15 and the first engaged portion 20 is also appropriately ensured. therefore, The mounting shaft portion 52 of the pull tab 50 can be smoothly inserted into the tab insertion gap 19, also, The mounting shaft portion 52 of the pull tab 50 can be smoothly moved to the space portion between the mounting main body portion 15c of the pull tab mounting portion 15 and the upper flap 11 via the tab insertion gap 19, And keep it in the space department.  Secondly, The operation of assembling the closing member 40 to the slider main body 10 holding the tab 50 is performed. In the assignment, As shown in Figure 14, The closing member 40 is inserted from the rear side of the slider main body 10 to the upper surface of the upper blade 11 and the free end portion 15b of the tab mounting portion 15. at this time, The closing member 40 is inserted in such a manner that the base portion 41 of the closing member 40 is placed on the upper surface of the upper blade 11. Further, the member guiding portion 25 of the first engaged portion 20 is inserted between the right and left insertion portions 42 of the closing member 40.  Then, The closing member 40 is pressed forward along the longitudinal direction of the slider. at this time, The member guiding portion 25 of the first engaged portion 20 is sequentially inserted into the gap between the right and left insertion portions 42 of the closing member 40 and the receiving groove portion 48 of the base portion 41, The closing member 40 can be stably advanced along the member guiding portion 25. With this, The left and right insertion portions 42 of the closing member 40 can be inserted between the right and left projecting portions 23 of the member holding portion 21 of the first engaged portion 20 and the upper blade 11 . also, The right and left locking claw portions 44 of the closing member 40 can be brought into contact with the locking restricting portions 33 of the second engaged portion 30.  and then, By pressing the closure member 40 forward, The left and right locking claw portions 44 of the closing member 40 are in sliding contact with the locking restricting portions 33 of the second engaged portion 30. With this, As above, The closing member 40 advances on one side, The left and right vertical wall portions 43 of the closing member 40 are elastically deformed so as to expand toward the outer side in the width direction of the slider. Thereby, the interval between the left and right locking claw portions 44 can be enlarged.  then, By the closing member 40, The left and right locking claw portions 44 of the closing member 40 are moved forward of the locking restriction portion 33 of the second engaged portion 30, With this, The left and right vertical wall portions 43 are elastically restored, Further, the left and right locking claw portions 44 are housed in the housing recessed portion 34 of the second engaged portion 30. With this, The closing member 40 is locked to the locking restricting portion 33 of the second engaged portion 30. also, Simultaneously, The left and right insertion portions 42 of the closing member 40 abut against the member abutting portion 24 of the first engaged portion 20 .  in this way, The closing member 40 is locked to the second engaged portion 30 of the handle mounting portion 15, Further, the closing member 40 abuts against the member abutting portion 24 of the first engaged portion 20 and is engaged with the member holding portion 21, And the closing member 40 is not in the front-rear direction with respect to the slider body 10, Left and right direction, The way of moving up and down is firmly installed. With this, The tab insertion gap 19 of the slider body 10 is closed by the closing member 40. Thereby, the assembly work of the slider 1 is completed.  By performing the assembly work as described above, On the other hand, the slider 1 of the present embodiment shown in Fig. 1 is obtained by attaching the pull tab 50 to the slider body 10 in which the handle attaching portion 15 is integrally formed.  In the slider 1 of the embodiment as described above, The flap 11 of the slider main body 10 is not formed with a groove-like member fitting portion 66 (see FIG. 16) as disclosed in Patent Document 1, or an insertion opening portion 77 (see FIG. 17) of Patent Document 2, therefore, The strength of the upper wing 11 can be stably ensured.  also, The first engagement portion 20 and the second engagement portion 30 of the slider body 10 can be formed by a mold for opening the mold in the width direction of the slider. therefore, Compared to the slider main body 61 which is formed, for example, in Patent Document 1 and Patent Document 2, In the case of 71, The construction of the mold for forming can be simplified. therefore, Expect to reduce the cost of the mold or extend the life of the mold. also, It is also expected to improve the productivity of the slider body 10.  and then, In the slider 1 of the embodiment, That is, the first engaged portion 20 is provided on the upper surface of the upper blade 11, The interval (height size) between the free end portion 15b of the tab attaching portion 15 and the first engaged portion 20 is also appropriately ensured as described above. therefore, The operation of attaching the pull tab 50 to the slider body 10 can be performed smoothly and relatively easily, Or the operation of mounting the closing member 40 on the slider body 10.  and, In the slider 1 of the embodiment, as shown in picture 2, The front surface of the member abutting portion 24 of the first engaged portion 20 of the slider main body 10 is formed to be inclined obliquely toward the rear direction. And the inclined upper surface of the central protrusion 47 of the closing member 40 is formed obliquely toward the rear direction. With this, When the pull tab 50 is pulled as described above and the slider 1 is slid rearward (the direction in which the element rows are separated), The front surface of the member abutting portion 24 of the first engaged portion 20 can be And the inclined upper surface of the central projection 47 of the closure member 40 easily guides the mounting shaft portion 52 of the tab 50 to the free end portion 15b of the tab mounting portion 15.  the result, The mounting shaft portion 52 of the pull tab 50 can be stably supported by the firmly formed tab mounting portion 15. at the same time, The closing member 40 attached to the slider body 10 can be prevented from being pushed rearward by the mounting shaft portion 52 of the tab 50. therefore, The engagement state of the closing member 40 with respect to the slider body 10 can be stably maintained, Therefore, it is difficult to cause the closing member 40 to be deviated from the slider main body 10 due to the operation of the tab 50.  especially, In this embodiment, The inclination angle of the front surface of the member abutting portion 24 is different from the inclination angle of the inclined upper surface of the central projection 47 of the closing member 40. and then, The inclination angle of the inclined upper surface of the central projection 47 with respect to the upper surface of the upper wing 11 is made smaller than the inclination angle of the front surface of the member abutment portion 24. With this, The space portion of the attachment shaft portion 52 of the pull tab 50 can be appropriately secured before the free end portion 15b of the handle attaching portion 15. at the same time, The mounting shaft portion 52 of the tab 50 can be easily guided toward the free end portion 15b of the tab mounting portion 15 by the upwardly inclined surface.  Furthermore, In the slider 1 of the above embodiment, The insertion portion 42 of the left and right sides of the closing member 40 is inserted between the upper flap 11 of the slider main body 10 and the protruding piece portion 23 of the member holding portion 21, The lower end surface of the base portion 41 of the closing member 40 is in contact with the upper surface of the upper blade 11, And an upper end surface of the left and right vertical wall portions 43 of the closing member 40 is in contact with the free end portion 15b of the tab mounting portion 15, And restricting the movement of the closing member 40 relative to the height of the slider of the slider body 10, Thereby, the position of the closing member 40 in the height direction of the slider can be stabilized.  however, In the present invention, E.g, As shown in Fig. 15, a cross-sectional view of the slider 1a according to a modification of the embodiment is shown. In addition to the constitution of the embodiment described above, The insertion groove portion 37 along the longitudinal direction of the slider may be formed on the second engaged portion 30a of the slider body 10a. Further, the locking piece portion 44a on the right and left sides of the closing member 40a forms the fitting piece portion 49 to be fitted into the fitting groove portion 37 of the second engaged portion 30a.  By forming the fitting groove portion 37 as described above corresponding to the insert piece portion 49, The movement of the closing member 40a relative to the slider height direction of the slider body 10a can be more effectively restricted, Thereby, the position of the closing member 40a in the height direction of the slider can be made more stable.  Furthermore, The slider 1a of this modification is formed in the same manner as the slider 1 of the above-described embodiment except that the above-described fitting recessed portion 37 and the inserting piece portion 49 are additionally formed. therefore, In the slider 1a shown in Fig. 15, The same or similar components as those of the slider 1 of the above-described embodiment are denoted by the same reference numerals as those of the above embodiment.  and then, In the slider 1 of the above embodiment, The locking restricting portion 33 that locks the closing member 40 attached to the slider body 10 and restricts the rearward movement is provided in the second engaged portion 30 of the slider body 10 (the free end portion 15b of the tab mounting portion 15) . also, The locking claw portions 44 of the closing member 40 that are locked to the locking restricting portions 33 of the slider main body 10 are provided at the upper end portions of the left and right vertical wall portions 43 of the closing member 40.  however, In the present invention, The locking restricting portion of the slider main body that restricts the movement of the closing member and the rearward movement may not be provided in the second engaged portion 30 of the slider main body 10 of the above embodiment.
