Description

Technical Field

[0001] The present invention relates to a slider for a slide fastener. Background Art

[0002] In International Publication No. 2018 / 100691 (Patent Document 1), there is described a method of using Figure 15 The slider 80 is formed of the parts shown in the figure. In the slider 80 of the patent document 1, the slider body 81, the stopper 82, the stopper member 83, the cover 84, and the leaf spring member 85 are used to form the slider body (also referred to as a primary assembly) of the slider 80. The stopper member 83 is held so as to be movable between a passing position where a pull-tab insertion gap formed between an upper wing plate 81a of the slider body 81 and a free end of the cover 84 is opened to allow the mounting shaft portion 86a of the pull-tab 86 to pass through, and a blocking position where the pull-tab insertion gap is blocked.

[0003] Thus, a desired pull tab 86 can be post-attached to the slider body of the slider 80 to which the cover body 84 is fixed. In the slider 80 to which the pull tab 86 can be post-attached, for example, the pull tab 86 can be easily selected according to the user's request or preference.

[0004] In addition, the slider 80 of Patent Document 1 includes an automatic stopping mechanism using a stopping claw body 82. Therefore, in the slide fastener, when the slider 80 is stopped at a desired position of the element row, the slider 80 can be held at the stopped position.

[0005] In the slider 80 of Patent Document 1, the stop pawl 82 and the stopper member 83 are arranged side by side with respect to the slider body 81 in the slider width direction. Thus, the height dimension of the entire slider 80 (the dimension in the slider height direction) can be suppressed from increasing. In addition, the slider body 81 can be formed in a simple shape, and the slider body can also be assembled relatively simply. Therefore, the cost of the slider 80 that can be installed with the pull tab 86 later can be reduced.

[0008] Patent Document 1: International Publication No. 2018 / 100691 Summary of the invention

[0009] In the slider 80 of Patent Document 1, as described above, the stop claw body 82 and the stopper member 83 are arranged side by side in the width direction of the slider, and there are cases where the stop claw body 82 and the stopper member 83 come into contact with each other. In addition, the positions of the stop claw body 82 and the stopper member 83 are difficult to stabilize. Therefore, for example, when the slider 80 is slid, when the stop claw body 82 is lifted by the mounting shaft portion 86a of the pull tab 86, the stopper member 83 may sometimes be lifted under the influence of the stop claw body 82.

[0010] Therefore, for example, when the pull tab 86 is operated in a manner of twisting relative to the slider body 81, the pull tab insertion gap blocked by the stopper member 83 will open to form an exit passage for the mounting shaft portion 86a. As a result, it is considered that the pull tab 86 may accidentally (or sporadically) fall off from the slider main body.

[0011] In addition, when assembling the slider main body of the slider 80, the position of the stop claw body 82 or the position of the stopper member 83 sometimes shifts, and it is also considered that this will reduce the assembly workability. In addition, due to the position shift of the stop claw body 82 or the stopper member 83, there is also a risk that the above-mentioned automatic stop mechanism of the stop claw body 82 will malfunction.

[0012] The present invention has been completed in view of the above-mentioned conventional problems, and its object is to provide a slider that can mount the pull tab on the slider main body later and can prevent the pull tab from accidentally falling off from the slider main body.

[0013] To achieve the above object, the slider provided by the present invention is a slider for a zipper, and has: a slider body in which a chain tooth guide path is formed between an upper wing plate and a lower wing plate; a pull tab having a mounting shaft portion; a stop claw body having a claw portion that can advance and retreat relative to the chain tooth guide path; a stopper member arranged side by side with the stop claw body in the width direction of the slider; and a cover body fixed to the upper wing plate in a cantilever shape. The chain tooth guide path communicates with the left and right shoulder openings provided at the front end portion in the length direction of the slider body and the rear opening provided at the rear end portion in the length direction. The feature of this slider is that a pull tab insertion gap through which the mounting shaft portion of the pull tab can be inserted is provided between the upper wing plate and the free end portion of the cover body. The stopper member is supported so as to be able to rotate between a passing position where the pull tab insertion gap is opened and a blocking position where the pull tab insertion gap is blocked, and has a shape that can move backward in the length direction when rotating from the blocking position to the passing position.

[0014] In the slider of the present invention, preferably, the stopper member has at least one tab portion that protrudes outward in the width direction so as to be able to interfere with the cover body.

[0015] In this case, preferably, the cover body has: an abutting portion that abuts against the tab portion when the stopper member rotates from the blocking position to the passing position to stop the rotation of the stopper member; and a housing space portion that houses the tab portion when the stopper member rotates from the blocking position to the passing position to allow the stopper member to rotate more largely toward the passing position compared to the state of abutting against the abutting portion, and the housing space portion of the cover body is disposed on the front side in the slider length direction compared to the abutting portion.

[0016] In the slider of the present invention, preferably, an installation support portion is provided on the upper wing plate, and the installation support portion has a support convex portion that rotatably supports the stop claw body and the stopper member. The stop claw body has a claw base end portion that engages with the support convex portion, and the claw base end portion has a claw side engagement surface that is arcuate in a side view of the stop claw body. The stopper member has a stopper base end portion that engages with the support convex portion, and the stopper base end portion has a retreat engagement surface that is formed in a straight line or in a curved shape that is gently curved compared to the claw side engagement surface and slopes obliquely downward toward the front in a side view of the stopper member.

[0017] In this case, preferably, the straight-line-shaped retreat engagement surface is inclined at an angle of 20° or more and 70° or less with respect to the slider length direction in a side view of the stopper member.

[0018] Further, preferably, the support convex portion of the installation support portion has a first support convex portion that rotatably supports the stop claw body and a second support convex portion that rotatably supports the stopper member, and the second support convex portion is disposed on the front side or the rear side in the slider length direction compared to the first support convex portion.

[0019] Further, preferably, a partition wall portion extending rearward from the first support convex portion and the second support convex portion is provided at a position between the first support convex portion and the second support convex portion.

[0020] Further, preferably, the stopper base end portion has a wide-width portion and a narrow-width portion that is disposed rearward compared to the wide-width portion and is thinner in the slider width direction compared to the wide-width portion. The installation support portion has a pair of holding wall portions extending rearward from the support convex portion that supports the stopper member and a housing gap formed between the pair of holding wall portions and housing the narrow-width portion.

[0021] Advantages of the Invention

[0022] According to the slider of the present invention, the pull tab can be mounted on the slider main body portion later, and accidental detachment of the pull tab from the slider main body portion can be suppressed. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Hereinafter, embodiments will be listed and the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0039] Figure 1 It is an exploded perspective view showing the state of the slider of this embodiment after being disassembled. Figures 2 - 6 Schematically represent Figure 1 The slider body part of the slider shown.

[0040] It should be noted that in the following description, the front-back direction refers to the length direction or the sliding direction of the slider. In particular, the direction in which the slider moves to engage the left and right rows of teeth is set as the front (the shoulder side direction), and the direction in which the slider moves to separate the rows of teeth (the rear mouth side direction) is set as the rear. In addition, the up-down direction refers to the height direction of the slider, for example, the direction orthogonal to the flat first upper surface of the upper wing plate of the slider body described later. In particular, the side where the mounting cover body (or the pull tab) is attached to the slider body of the slider is set as the upper side, and the direction opposite thereto is set as the lower side. In addition, the left-right direction refers to the width direction of the slider, which is the direction orthogonal to the sliding direction and the height direction of the slider.

[0041] The slider 1 for a zipper of this embodiment is formed by attaching a pull tab 5 to Figures 2 - 6 the slider body part 2 (also referred to as a primary assembly) shown. As Figure 1 shown, this slider 1 has a slider body 10, a cover body 30, a stop pawl body 40, a stopper member 50, a leaf spring member 60 (also referred to as a biasing member), and a pull tab 5. In this case, the slider body part 2 is formed by five parts: a slider body 10, a cover body 30, a stop pawl body 40, a stopper member 50, and a leaf spring member 60. In addition, the slider 1 of this embodiment is provided with an automatic stop mechanism based on the stop pawl body 40.

[0042] In this embodiment, the slider body 10, the cover body 30, the stop pawl body 40, the stopper member 50, the leaf spring member 60, and the pull tab 5 are made of metal. It should be noted that the materials of the above-mentioned respective parts are not limited, and at least some of the parts may be made of thermoplastic resin.

[0043] The slider body 10 has: an upper wing plate 20; a lower wing plate 11 disposed in parallel with the upper wing plate 20; a connecting column 12 that connects the front end portion (shoulder side end portion) of the upper wing plate 20 and the front end portion (shoulder side end portion) of the lower wing plate 11; left and right upper flange portions 13 provided on the left and right side portions of the upper wing plate 20; and left and right lower flange portions 14 provided on the left and right side portions of the lower wing plate 11. In this case, the upper flange portion 13 extends downward from the upper wing plate 20 toward the lower wing plate 11. The lower flange portion 14 extends upward from the lower wing plate 11 toward the upper wing plate 20.

[0044] The slider body 10 has a mounting support portion 21 provided at the front end portion of the upper wing plate 20 and protruding upward, and a fitting recess 22 for fitting a part (fixed end portion) of the cover body 30. At the front end portion of the slider body 10, left and right shoulder openings are formed with the connecting column 12 sandwiched therebetween. A rear opening is formed at the rear end portion of the slider body 10. A substantially Y-shaped chain tooth guide path 15 that communicates the left and right shoulder openings and the rear opening is formed between the upper wing plate 20 and the lower wing plate 11 of the slider body 10.

[0045] At the left and right side edges of the slider body 10, there are provided belt insertion gaps for inserting a zipper tape (not shown). In this case, the left and right belt insertion gaps in the slider body 10 are formed between the left and right upper flange portions 13 and the left and right lower flange portions 14.

[0046] The upper wing plate 20 has a first upper surface (main upper surface) 23a on which the mounting shaft portion 8 is placed when the pull tab 5 is not operated, and a second upper surface (rear end side upper surface) 23b formed at the rear end portion of the upper wing plate 20 and at a height position lower than the first upper surface 23a. In addition, a step portion 23c that slopes downward toward the rear is provided between the first upper surface 23a and the second upper surface 23b. By providing the step portion 23c in this way and disposing the second upper surface 23b lower than the first upper surface 23a, it is possible to easily insert the mounting shaft portion 8 of the pull tab 5 into the pull tab insertion gap 16 formed between the upper wing plate 20 and the free end portion of the cover body 30. In addition, it is possible to easily bring the mounting shaft portion 8 of the pull tab 5 into contact with the rear end portion of the stopper member 50. Between the mounting support portion 21 and the step portion 23c of the slider body 10, there is provided a claw hole 24 that penetrates from the first upper surface 23a of the upper wing plate 20 to the chain tooth guide path 15.

[0047] The mounting support portion 21 disposed at the front end of the upper wing plate 20 has: a base portion 21a connected to the bottom surface of the fitting recess 22; a first support convex portion 21b and a second support convex portion 21c protruding upward from the base portion 21a; and a pair of left and right holding wall portions 21d extending rearward from the second support convex portion 21c. The base portion 21a has a width dimension larger than the sum of the width dimension (dimension in the slider width direction) at the claw base end portion 41 of the stop claw body 40 described later and the width dimension at the stopper base end portion 51 of the stopper member 50 described later. The upper surface of the base portion 21a is disposed in front of the first support convex portion 21b and the second support convex portion 21c, and is formed as an inclined surface that slopes downward toward the front.

[0048] For example, as Figure 1 and Figure 7 shown, the first support convex portion 21b is provided at the rear end of the mounting support portion 21. In addition, the first support convex portion 21b is disposed on one side (right side) in the left-right direction compared to the center position in the width direction of the mounting support portion 21. When observing a cross-section orthogonal to the slider width direction (refer to Figure 5 ), the upper end surface (top end surface) of the first support convex portion 21b is formed as a curved surface that curves upward in a convex shape in an arc shape or a shape close to an arc. The stop claw body 40 is supported on the first support convex portion 21b in a rotatable or swingable manner.

[0049] The second support convex portion 21c is provided at the rear end of the mounting support portion 21 and is disposed on the other side (left side) in the left-right direction compared to the first support convex portion 21b. In addition, the second support convex portion 21c is disposed at a position offset forward (toward the shoulder side direction) compared to the first support convex portion 21b in the slider length direction. Therefore, the side wall surface on the right side of the second support convex portion 21c (in other words, the stepped surface between the first support convex portion 21b and the second support convex portion 21c) is disposed on the front side compared to the first support convex portion 21b. In addition, in the present embodiment, the second support convex portion 21c may also be disposed at a position offset rearward (toward the rear opening side direction) compared to the first support convex portion 21b in the slider length direction.

[0050] When observing a cross-section orthogonal to the slider width direction (refer to Figure 6 ), the upper end surface (top end surface) of the second support convex portion 21c is formed as a curved surface that curves upward in a convex shape in an arc shape or a shape close to an arc. The stopper member 50 is supported on the second support convex portion 21c in a rotatable or swingable manner.

[0051] The left and right holding wall portions 21d extend rearward from the second support convex portion 21c. For example, as Figure 10As shown, a receiving gap for receiving the narrow portion 56 of the stopper member 50 described later is provided between the left and right holding wall portions 21d. In the present embodiment, the outer side surface of the left holding wall portion 21d and the left side wall surface of the second support convex portion 21c are continuously provided so as to form a flat surface.

[0052] In addition, the right holding wall portion 21d of the pair of left and right holding wall portions 21d, which is disposed close to the first support convex portion 21b, also extends rearward from the first support convex portion 21b. The right holding wall portion 21d also serves as a partition wall portion disposed at a position between the first support convex portion 21b and the second support convex portion 21c. By this right holding wall portion (partition wall portion) 21d, the positions of the stop claw body 40 and the stopper member 50 in the slider width direction can be stabilized, and contact between the stop claw body 40 and the stopper member 50 can also be prevented or suppressed.

[0053] The fitting recess 22 of the slider body 10 is provided rearward from the front edge of the upper wing plate 20 so as to correspond to the shape of the later-described cover flange portion 32 of the cover body 30. In addition, the fitting recess 22 is continuously provided in a range from the front to the left and right sides of the mounting support portion 21. In a state where the cover body 30 is not fixed to the slider body 10 (refer to Figure 1 ), the left and right raised portions 25 protruding from the first upper surface 23a of the upper wing plate 20 are provided on the left and right sides of the mounting support portion 21 so as to be away from the mounting support portion 21. In the assembly process of the slider main body portion 2, after the cover flange portion 32 of the cover body 30 is inserted and received in the fitting recess 22 of the slider body 10, by pressing the left and right raised portions 25 from above and plastically deforming them, the plastically deformed portion of the upper wing plate 20 can be used to press and fix the cover flange portion 32.

[0054] A pair of left and right longitudinal wall portions 26 are provided at the step portion 23c of the upper wing plate 20. The left and right longitudinal wall portions 26 project upward from the inclined surface of the step portion 23c in a substantially triangular shape. In addition, the left and right longitudinal wall portions 26 are disposed separately from each other in the slider width direction, and an interval into which the later-described stopper rear end portion 53 of the stopper member 50 can be inserted is provided between the left and right longitudinal wall portions 26.

[0055] In the present embodiment, by inserting the stopper rear end portion 53 of the stopper member 50 between the left and right longitudinal wall portions 26 and inserting and receiving the later-described narrow portion 56 of the stopper member 50 between the left and right holding wall portions 21d provided on the mounting support portion 21, the position of the stopper member 50 relative to the slider body 10 (especially the position in the slider width direction) is as Figure 9 shown, so that the stopper member 50 can be stably held at a specified position.

[0056] In a side view, the cover body 30 of this embodiment is substantially L-shaped or substantially concave. The cover body 30 has a bottomed box-shaped cover main body portion 31 with an opening at the bottom, and left and right cover flange portions 32 extending in the left and right directions from the front lower end portion of the cover main body portion 31. By fixing one end portion (front lower end portion) of the cover body 30 to the front end portion of the upper wing plate 20, the cover body 30 is mounted on the slider body 10 in a cantilever manner. In this case, the front lower end portion of the cover body 30 becomes the fixed end portion of the cover body 30.

[0057] In addition, by mounting the cover body 30 on the slider body 10 in a cantilever manner, a tab insertion gap 16 through which the mounting shaft portion 8 of the tab 5 can be inserted is provided between the other end portion (free end portion, rear end portion) of the cover body 30 and the upper wing plate 20 of the slider body 10. Here, the other end portion of the cover body 30 includes a portion that is disposed opposite to the range from the stepped portion 23c of the upper wing plate 20 to the rear end edge in a side view of the slider main body portion 2 of the slider 1 (refer to Figure 4 ).

[0058] In a side view of the slider main body portion 2 ( Figure 4 ), a holding space portion 17 capable of accommodating and holding the mounting shaft portion 8 of the tab 5 is formed between the first upper surface 23a of the upper wing plate 20 and the cover body 30 between the fixed end portion and the free end portion of the tab 5 in the slider length direction. In addition, within the holding space portion 17, a limiting space portion for restricting (defining) the movable range of the mounting shaft portion 8 is formed by the stop claw body 40 and the stopper member 50.

[0059] The cover main body portion 31 has a top portion 33 continuously disposed from the front surface of the cover main body portion 31 via the upper surface to the rear surface, and left and right side wall portions 34 extending downward from the left and right side edge portions of the top portion 33 toward the upper wing plate 20. An internal space surrounded by the top portion 33 and the left and right side wall portions 34 is formed inside the cover main body portion 31, and a part of the stop claw body 40 and a part of the stopper member 50 are accommodated in the internal space of the cover main body portion 31.

[0060] The left and right side wall portions 34 in the cover main body portion 31 have side wall lower end edges 34a disposed opposite to the upper wing plate 20. In addition, the side wall lower end edges 34a of the left and right side wall portions 34 have: a first lower end edge 34b disposed around the holding space portion 17 in a side view of the slider main body portion 2 ( Figure 4 ); a second lower end edge 34c disposed along the tab insertion gap 16; and a corner portion disposed between the first lower end edge 34b and the second lower end edge 34c.

[0061] In addition, in this embodiment, an abutting portion 35 is provided on the left and right side wall lower end edges 34a in the cover main body portion 31. When the mounting shaft portion 8 in the holding space portion 17 is lifted by operating the tab 5 mounted on the slider 1, for example, asFigure 5 and Figure 14 As shown in Figure 14 , the abutting portion 35 abuts against the left and right tab portions 53b of the stopper member 50 described later. In this case, the abutting portion 35 is provided at the second lower end edge 34c of the left and right side wall portions 34.

[0062] In the cover body 30 (cover main body portion 31) of the present embodiment, a housing space portion 36 is provided. When the mounting shaft portion 8 of the pull tab 5 is passed through the pull tab insertion gap 16 in order to mount the pull tab 5 to the slider body portion 2, for example, as Figure 12 shown, the housing space portion 36 can house the left and right tab portions 53b of the stopper member 50 pushed forward by the mounted shaft portion 8. In this case, the housing space portion 36 provided in the cover body 30 is disposed on the front side compared to the abutting portion 35 when the slider body portion 2 or the slider 1 is viewed from the side ( Figure 4 or Figure 12 ).

[0063] In the present embodiment, the housing space portion 36 is a space portion surrounded in part by the first lower end edges 34b of the left and right side wall portions 34. In particular, as Figure 12 shown, it is a space portion surrounded by the first lower end edges 34b of the left and right side wall portions 34 and the raised stop claw body 40. In addition, the housing space portion 36 is formed by a part of the holding space portion 17 formed between the upper wing plate 20 and the cover body 30.

[0064] By housing the tab portion 53b of the stopper member 50 in such a housing space portion 36, for example, compared to the case where the tab portion 53b of the stopper member 50 abuts against the abutting portion 35 of the cover body 30 (see Figure 14 ), the stopper member 50 can be allowed to rotate upward by a greater amplitude.

[0065] On the inner surface of the top portion 33 of the cover main body portion 31, as Figure 5 etc. shown, front and rear spring holding portions 37 for holding one end portion and the other end portion of the leaf spring member 60 are provided on the top portion 33. The leaf spring member 60 is held in the inner space of the cover body 30 in a manner capable of elastic deformation by the front and rear spring holding portions 37 provided in the cover main body portion 31. It should be noted that in the present invention, the structure, means, and method for holding the leaf spring member 60 inside the cover main body portion 31 are not particularly limited.

[0066] The stop claw body 40 of the present embodiment has: a claw base end portion 41 supported rotatably (or swingably) on the mounting support portion 21 of the slider body 10; upper and lower arm portions 42 and 43 branched from the claw base end portion 41 into two branches and extending rearward; and a claw portion 44 protruding downward at the rear end portion of the lower arm portion 43. The claw portion 44 of the stop claw body 40 is formed to be able to advance and retreat relative to the tooth guide path 15 via the claw hole 24 of the slider body 10.

[0067] The claw base end portion 41 of the stop claw body 40 has a shape that engages with the first support convex portion 21b of the mounting support portion 21 covering the slider body 10, whereby it is supported rotatably on the first support convex portion 21b. The claw base end portion 41 has a claw-side engaging surface 45 that is curved in an arc shape when viewed from the side of the stop claw body 40. The claw-side engaging surface 45 is curved into a concave shape. In addition, the claw base end portion 41 has a space portion that opens downward, and the first support convex portion 21b of the mounting support portion 21 is inserted into this space portion.

[0068] A space portion that opens rearward is formed between the upper arm portion 42 and the lower arm portion 43 of the stop claw body 40, and the mounting shaft portion 8 of the pull tab 5 inserted through the pull tab insertion gap 16 is housed in the space portion of the stop claw body 40.

[0069] When the stop claw body 40 is mounted on the slider body 10, as Figure 9 shown, the directions of the claw base end portion 41 and the upper arm portion 42 are aligned with the slider length direction, and the claw base end portion 41 engages with the first support convex portion 21B of the mounting support portion 21 so as to cover the first support convex portion 21B from above. At the same time, the claw portion 44 is inserted into the claw hole 24 of the slider body 10. Thus, the stop claw body 40 is held at a specified position of the slider body 10. In this case, the stop claw body 40 contacts the first support convex portion 21b of the mounting support portion 21 and is held such that the upper arm portion 42, the lower arm portion 43, and the claw portion 44 can rotate relative to the slider body 10 in the vertical direction (slider height direction).

[0070] The stopper member 50 of the present embodiment is a member that blocks (prevents) the pull tab insertion gap 16 when the mounting shaft portion 8 of the pull tab 5 is housed between the upper arm portion 42 and the lower arm portion 43 of the stop claw body 40, so that the mounting shaft portion 8 of the pull tab 5 does not protrude outward through the pull tab insertion gap 16. As Figure 1 and Figure 8 shown, the stopper member 50 has: a stopper base end portion 51 disposed at the front end portion of the stopper member 50 and rotatably supported on the mounting support portion 21 of the slider body 10; a columnar stopper intermediate portion (bridging portion) 52 extending rearward from the stopper base end portion 51; and a stopper rear end portion 53 connected to the stopper intermediate portion.

[0071] A space portion that opens downward is formed in the stopper member 50 so as to be surrounded by the stopper base end portion 51, the stopper intermediate portion 52, and the stopper rear end portion 53. The mounting shaft portion 8 of the pull tab 5 inserted through the pull tab insertion gap 16 is housed in the space portion of the stopper member 50. In this case, the stopper member 50 and the stop claw body 40 together limit the movable range of the mounting shaft portion 8.

[0072] The stopper base end portion 51 of the stopper member 50 has a shape that engages with the second support convex portion 21c so as to cover the installation support portion 21 of the slider body 10, whereby it is rotatably supported by the second support convex portion 21c. The stopper base end portion 51 has a space portion that opens downward, and the second support convex portion 21c of the installation support portion 21 is inserted into the space portion.

[0073] The stopper base end portion 51 has a bent engagement surface 54a that is bent in an arc shape when viewed from the side of the stopper member 50 so as to surround the space portion, and a retreat engagement surface 54b that extends linearly. In this case, the retreat engagement surface 54b is provided at the front portion of the stopper base end portion 51 in a direction that slopes obliquely downward toward the front. The bent engagement surface 54a is bent into a concave shape and continuously extends rearward from the rear end of the retreat engagement surface 54b.

[0074] In the stopper member 50 provided with the retreat engagement surface 54b as described above, during the operation of being lifted by the mounting shaft portion 8 of the pull tab 5 from the blocking position ( Figure 11 ) and rotating while contacting the second support convex portion 21c of the installation support portion 21, the linear retreat engagement surface 54b contacts the first support convex portion 21b of the installation support portion 21, whereby the stopper member 50 can be moved rearward while rotating. That is, the position of the stopper member 50 can be moved rearward during rotation by the retreat engagement surface 54b of the stopper base end portion 51.

[0075] In addition, in the present embodiment, although there is no particular limitation on the inclination angle of the linear retreat engagement surface 54b with respect to the slider length direction or the slider height direction when viewed from the side of the stopper member 50, in order to appropriately move the position of the stopper member 50 rearward when the stopper member 50 rotates, for example, as Figure 8 shown, the inclination angle θ of the retreat engagement surface 54b with respect to the slider length direction is preferably 20° or more and 70° or less, more preferably 30° or more and 60° or less. By making the above inclination angle θ 20° or more, especially 30° or more, the rearward movement of the stopper member 50 can be effectively promoted. In addition, by making the above inclination angle θ 70° or less, especially 60° or less, the stopper member 50 can rotate smoothly when the stopper member 50 is lifted.

[0076] The stopper base end portion 51 has a wide portion 55 disposed on the front side of the stopper base end portion 51 and a narrow portion 56 having a smaller width dimension (dimension in the slider width direction) than the wide portion 55. In this case, the wide portion 55 is formed with the same width dimension as the main body portion disposed above the stopper base end portion 51. The narrow portion 56 is continuously formed rearward from the wide portion 55 and downward from the main body portion of the stopper base end portion 51.

[0077] By providing a thin narrow portion 56 at the stopper base end portion 51, when the stopper member 50 is held on the mounting support portion 21 of the slider body 10, the narrow portion 56 can be easily inserted between the left and right holding wall portions 21d of the mounting support portion 21 and housed in the housing gap between the holding wall portions 21d. Thus, the positioning of the stopper member 50 relative to the slider body 10 can be simply performed, and the stopper member 50 can be stably held at a specified position.

[0078] The stopper intermediate portion 52 extends rearward from the stopper base end portion 51 so as to have the same width dimension (or substantially the same width dimension) as the wide portion 55. In the present embodiment, for example, as Figure 9 shown, when the stop claw body 40 and the stopper member 50 are held on the slider body 10, the stop claw body 40 and the stopper member 50 are arranged along the slider length direction, and the stopper member 50 and the stop claw body 40 are arranged side by side in the slider width direction. Here, the stopper member 50 and the stop claw body 40 being arranged side by side in the slider width direction means that at least a part of the stopper member 50 is arranged side by side in the lateral direction (left - right direction) along the stop claw body 40. For example, in the case of the present embodiment, in the stopper member 50, the stopper base end portion 51 and the stopper intermediate portion 52, which are the portions corresponding to the stop claw body 40 in the slider length direction, are arranged along the slider length direction, and these stopper base end portion 51 and stopper intermediate portion 52 are arranged side by side relative to the stop claw body 40 in the slider width direction.

[0079] The stopper rear end portion 53 has: a stopper main body portion 53a having a width dimension larger than that of the stopper base end portion 51 and the stopper intermediate portion 52; a pair of left and right tab portions 53b protruding from the stopper main body portion 53a in the slider width direction; and a hooking portion 53c provided at the front end portion of the stopper main body portion 53a.

[0080] The stopper main body portion 53a of the stopper rear end portion 53 is formed to be sized such that it can be housed inside the cover main body portion 31 when the stopper member 50 rotates upward from the blocking position. The left and right tab portions 53b in the stopper rear end portion 53 protrude outward along the slider width direction from the left and right side surfaces of the stopper main body portion 53a.

[0081] In this case, the protruding length (i.e., the width dimension of the left and right tab portions 53b) of the left and right tab portions 53b protruding from the stopper main body portion 53a is set to a size such that it can abut against the above - mentioned left and right abutting portions 35 of the cover body 30 when the stopper member 50 rotates upward from the blocking position. Additionally, for example, as Figure 12As shown, the tab portions 53b on the left and right are formed to have a size that can be accommodated in the accommodation space portion 36 of the cover body 30 when the mounting shaft portion 8 of the pull tab 5 is inserted from the rear of the slider body portion 2 and passed through the pull tab insertion gap 16.

[0082] The hooking portion 53c of the stopper rear end portion 53 has a curved surface that slopes downward with the front end face of the hooking portion 53c facing forward when viewed from the side of the stopper member 50. Thus, for example, as Figure 14 shown, when the pull tab 5 is operated, it is possible to easily introduce the mounting shaft portion 8 of the pull tab 5 into the space portion surrounded by the stopper intermediate portion 52 and the stopper rear end portion 53 of the stopper member 50, making it difficult for the mounting shaft portion 8 of the pull tab 5 to move downward of the stopper rear end portion 53.

[0083] In the present embodiment, the hooking portion 53c is provided only on a part of the stopper rear end portion 53 in the slider width direction. Specifically, the hooking portion 53c is provided in the range in the same width direction as the stopper intermediate portion 52 below the stopper intermediate portion 52. Thus, when the stop pawl body 40 and the stopper member 50 are respectively rotated in the slider 1, it is possible to prevent the hooking portion 53c of the stopper member 50 from contacting the stop pawl body 40. Therefore, it is possible to prevent the stop pawl body 40 and the stopper member 50 from interfering with each other and affecting their respective rotational movements.

[0084] The leaf spring member 60 of the present embodiment is formed by punching out a metal piece of a predetermined shape from a continuous long metal plate such as stainless steel. In addition, bending processing can be performed on the leaf spring member 60 as needed. At one end portion (front end portion) and the other end portion (rear end portion) of the leaf spring member 60, hole portions 61 that open in a manner of being cut out inward from the front end edge and the rear end edge of the leaf spring member 60 are respectively formed.

[0085] The leaf spring member 60 of the present embodiment is mounted inside the cover body 30 by being held by the spring holding portion 37 of the cover body 30 using the hole portions 61. The leaf spring member 60 is mounted inside the cover body 30 as a separate biasing member that biases the stop pawl body 40 so that the claw portion 44 protrudes into the tooth guide path 15 of the slider body 10 and biases the stopper member 50 toward the blocking position.

[0086] The pull tab 5 of the present embodiment has: a thin plate-shaped pull tab main body portion 6; left and right arm portions 7 extending from one end portion of the pull tab main body portion 6; and a mounting shaft portion (connecting portion) 8 that connects between the top end portions of the left and right arm portions 7. The cross section of the mounting shaft portion 8 orthogonal to the axial direction is circular. An opening window portion in the shape of a rectangle surrounded by the pull tab main body portion 6, the left and right arm portions 7, and the mounting shaft portion 8 is formed on the pull tab 5. It should be noted that in the present invention, the shape, size, material, etc. of the pull tab 5 are not particularly limited.

[0087] Next, a manufacturing method of the slider 1 of the present embodiment will be described.

[0088] In the present embodiment, the slider 1 is first assembled Figures 2 - 6 in the assembling process of the slider main body portion 2 shown, and then, a tab installation process of installing the tab 5 on the obtained slider main body portion 2 is performed.

[0089] In the assembling process of the slider main body portion 2, first, a first assembling process of installing the stop claw body 40 and the stopper member 50 on the slider body 10 is performed. In the present embodiment, the stop claw body 40 is first installed and held on the slider body 10. At this time, the claw-side engaging surface 45 of the claw base end portion 41 is placed on the first support convex portion 21b of the mounting support portion 21 so that the claw base end portion 41 of the stop claw body 40 covers the first support convex portion 21b from above, whereby the claw base end portion 41 is engaged with the first support convex portion 21b. At the same time, the claw portion 44 and the lower arm portion 43 of the stop claw body 40 are inserted into the claw hole 24 of the slider body 10.

[0090] Thereby, as Figure 9 shown, the stop claw body 40 can be easily placed and held at a specified position on the slider body 10. The stop claw body 40 held on the slider body 10 is arranged in a posture along the slider length direction, and is rotatably supported by the mounting support portion 21 of the slider body 10 in such a manner that the claw portion 44 enters and exits the tooth guide path 15 of the slider body 10.

[0091] Next, the stopper member 50 is installed and held on the slider body 10 holding the stop claw body 40. Specifically, the stopper base end portion 51 is placed on the second support convex portion 21c of the mounting support portion 21 so that the stopper base end portion 51 of the stopper member 50 covers the second support convex portion 21c from above, whereby the stopper base end portion 51 is engaged with the second support convex portion 21c. At this time, the narrow portion 56 of the stopper base end portion 51 is inserted and housed between the left and right holding wall portions 21d of the mounting support portion 21. At the same time, the stopper rear end portion 53 is inserted and housed between the left and right longitudinal wall portions 26 provided on the upper wing plate 20. Thereby, the stopper member 50 can be easily placed and held at a specified position adjacent to the stop claw body 40 on the slider body 10. The stopper member 50 held on the slider body 10 is rotatably supported by the mounting support portion 21.

[0092] By performing the above first assembling process, the stop claw body 40 and the stopper member 50 are held on the slider body 10 as Figure 9 shown. At this time, the stop claw body 40 and the stopper base end portion 51 and the stopper intermediate portion 52 of the stopper member 50 are arranged along the slider length direction and are arranged side by side with each other in the slider width direction.

[0093] In addition, the first support convex portion 21b and the second support convex portion 21c of the slider body 10 are arranged offset in the front-rear direction, and a partition wall portion (the right-side holding wall portion 21d) is provided at a position between the first support convex portion 21b and the second support convex portion 21c. Thereby, contact between the stop claw body 40 held on the slider body 10 and the stopper member 50 is prevented or suppressed.

[0094] In addition, in this case, when viewing the slider body 10, the stop claw body 40, and the stopper member 50 from above, the stop claw body 40 and the stopper member 50 are arranged at positions where the claw base end portion 41 and the upper side arm portion 42 of the stop claw body 40 do not overlap with the stopper member 50. By arranging the stop claw body 40 and the stopper member 50 in this way, during the assembly process of the slider main body portion 2, they can be simply assembled and held without interference between the stopper member 50 and the stop claw body 40. Therefore, the assembly workability of the slider main body portion 2 can be improved.

[0095] During the assembly process of the slider main body portion 2, in addition to the above-mentioned first assembly process, a second assembly process of installing the leaf spring member 60 inside the cover body 30 is performed. In this second assembly process, the leaf spring member 60 is combined with the inner surface side of the top portion 33 of the cover body 30 in such a way that the front and rear hole portions 61 formed on the leaf spring member 60 are aligned with the spring holding portion 37 of the cover body 30. In addition, the spring holding portion 37 of the cover body 30 is pressed to cause plastic deformation. Thereby, the leaf spring member 60 can be elastically deformed and installed inside the cover body 30.

[0096] After the first assembly process and the second assembly process are performed, a third assembly process of assembling and fixing the cover body 30 on which the leaf spring member 60 is installed to the slider body 10 holding the stop claw body 40 and the stopper member 50 is performed.

[0097] In this third assembly process, first, the front lower end portion of the cover main body portion 31 and the cover flange portion 32 are inserted and received into the fitting recess 22 provided at the front end portion of the upper wing plate 20. Then, the left and right raised portions 25 provided on the upper wing plate 20 are locally pressed from above to cause plastic deformation in a flattened manner. Thereby, a part of the upper wing plate 20 can be made to sink into the cover flange portion 32 to press it, so that the cover body 30 can be fixed to the slider body 10. It should be noted that in the present invention, the method or means for fixing the cover body 30 to the slider body 10 is not particularly limited, and for example, bonding or welding can also be used.

[0098] Thereby, it is possible to manufacture Figures 2 - 6 the slider main body portion 2 as shown.

[0099] In the slider body portion 2 obtained by performing the above-described assembling processes (the first assembling process to the third assembling process), the stop claw body 40 and the stopper member 50 are rotatably supported on the mounting support portion 21 of the slider body 10 without contacting each other. In particular, the stopper member 50 is supported so as to be able to rotate between a blocking position (a position where the stopper rear end portion 53 contacts the upper wing plate 20) that blocks the insertion gap 16 for the pull tab formed between the upper wing plate 20 of the slider body 10 and the free end portion of the cover body 30 to prevent the mounting shaft portion 8 of the pull tab 5 from passing through, and a passing position (a position where the stopper rear end portion 53 does not overlap with the insertion gap 16 for the pull tab when viewed from the side of the slider body portion 2) that opens the insertion gap 16 for the pull tab to allow the mounting shaft portion 8 of the pull tab 5 to pass through the insertion gap 16, in the vertical direction.

[0100] In addition, the stop claw body 40 and the stopper member 50 are urged by a leaf spring member 60 attached to the cover body 30. In this case, the claw portion 44 of the stop claw body 40 enters the tooth guide path 15 of the slider body 10 by receiving a force (elastic force) from the leaf spring member 60. The stopper portion is held in the blocking position by receiving a force applied from the leaf spring member 60 in the direction from the above-described passing position toward the blocking position.

[0101] Next, a pull tab mounting process for mounting the pull tab 5 to the manufactured slider body portion 2 will be described.

[0102] In this pull tab mounting process, first, as Figure 11 shown, the mounting shaft portion 8 of the pull tab 5 is inserted into the insertion gap 16 for the pull tab formed between the upper wing plate 20 of the slider body 10 and the free end portion of the cover body 30 from the rear of the slider body portion 2. In addition, the mounting shaft portion 8 is brought into contact with the stopper rear end portion 53 of the stopper member 50 and pushed thereagainst. As a result, the mounting shaft portion 8 of the pull tab 5 can be inserted between the stopper rear end portion 53 of the stopper member 50 and the stepped portion 23c of the upper wing plate 20, and the stopper member 50 is rotated upward against the force of the leaf spring member 60 from the blocking position where the stopper rear end portion 53 contacts the upper surface of the upper wing plate 20. In addition, at this time, by bringing the mounting shaft portion 8 of the pull tab 5 into contact with the stopper rear end portion 53 from the rear, the stopper member 50 can be pushed forward.

[0103] Next, by further pushing the mounting shaft portion 8 of the pull tab 5 forward, the mounting shaft portion 8 moves along the insertion gap 16 for the pull tab as Figure 12 shown. As a result, the stopper member 50 is further lifted by the mounting shaft portion 8 and rotated upward. At this time, since the stopper member 50 is rotated upward while being pushed forward, the tab portions 53b provided on the left and right of the stopper member 50 can smoothly enter and be accommodated in the accommodation space portion 36 provided in the cover body 30 without contacting the contact portion 35 of the cover body 30.

[0104] That is, in the slider 1 of the present embodiment, when performing the operation of attaching the pull tab 5 to the slider body portion 2, when the stopper member 50 is rotated upward from the blocking position toward the passing position, by accommodating the left and right tab portions 53b of the stopper member 50 in the accommodation space portion 36 of the cover body 30 as described above, for example, compared to the case where the tab portion 53b abuts against the abutting portion 35 of the cover body 30 (refer to Figure 14 ), the stopper member 50 can be rotated upward by a larger amplitude. As a result, the stopper member 50 can be smoothly rotated to the passing position where the mounting shaft portion 8 of the pull tab 5 can pass through the pull tab insertion gap 16.

[0105] In addition, the mounting shaft portion 8 of the pull tab 5 pushed forward abuts against the rear end portion of the upper arm portion 42 of the stop claw body 40, and the upper arm portion 42 is lifted upward to rotate the stop claw body 40 upward. Thus, as Figure 13 shown, the mounting shaft portion 8 of the pull tab 5 can enter and be accommodated in the space below the stopper intermediate portion 52 of the stopper member 50 and between the upper arm portion 42 and the lower arm portion 43 of the stop claw body 40.

[0106] In addition, when the mounting shaft portion 8 of the pull tab 5 enters between the upper arm portion 42 and the lower arm portion 43 of the stop claw body 40, the stopper member 50 receives a force from the leaf spring member 60 and rotates from the above-described passing position to the blocking position to block the pull tab insertion gap 16, and maintains the pull tab insertion gap 16 in a blocked state. In addition, the stop claw body 40 receives a force from the leaf spring member 60 and rotates downward, so that the claw portion 44 of the stop claw body 40 protrudes into the tooth guiding path 15. Thus, the pull tab attachment process is completed.

[0107] As described above, in the pull tab attachment process, by performing a simple operation of inserting the pull tab 5 from the rear of the slider body portion 2 into the pull tab insertion gap 16 and pushing it forward along the pull tab insertion gap 16, the pull tab 5 can be easily and quickly attached to the slider body portion 2. Thus, the slider 1 of the present embodiment in which the pull tab 5 is attached to the slider body portion 2 can be manufactured. In addition, in the slider 1 of the present embodiment, after the assembly process of assembling the slider body portion 2, the pull tab attachment process can be continuously performed from the assembly process, or the pull tab attachment process can be performed at a desired time after leaving a time gap after the assembly process.

[0108] In the slider 1 of the present embodiment, when the pull tab 5 is in a free state (non-operating state) where it is not being operated, since the stop claw body 40 is urged by the leaf spring member 60, the claw portion 44 enters the tooth guide path 15 of the slider body 10. Therefore, when a zipper is formed using the slider 1 of the present embodiment, the slider 1 is provided with an automatic stop mechanism based on the stop claw body 40 that can hold the slider 1 relative to the tooth row at its stop position.

[0109] In the slider 1 of the present embodiment having such an automatic stop mechanism, when the slider 1 is slid, the user pulls the pull tab 5 and raises the mounting shaft portion 8 of the pull tab 5 as Figure 14 shown. In addition, Figure 14 shows a case where the slider 1 is slid rearward by pulling the pull tab 5 rearward with respect to the slider main body portion 2.

[0110] When the user pulls the pull tab 5, the mounting shaft portion 8 of the pull tab 5 can raise the stop claw body 40 and rotate it upward. As a result, since the claw portion 44 of the stop claw body 40 disengages from the tooth guide path 15 of the slider body 10, the automatic stop mechanism based on the stop claw body 40 is released, and the slider 1 can be freely slid along the tooth row.

[0111] Here, if the operation when releasing the automatic stop mechanism of the slider 1 is further specifically described, in the slider 1 of the present embodiment, when the pull tab 5 is not being operated, as Figure 13 shown, the lower end edge of the upper side arm portion 42 of the stop claw body 40 is located below the lower end edge of the stop intermediate portion 52 of the stop member 50. Therefore, in the initial stage when the pull tab 5 is pulled as described above to raise the mounting shaft portion 8 against the urging force of the leaf spring member 60 in order to slide the slider 1, the mounting shaft portion 8 can abut against the upper side arm portion 42 of the stop claw body 40 and smoothly raise the stop claw body 40.

[0112] In addition, at this time, due to the positional relationship of the first support convex portion 21b and the second support convex portion 21c of the slider body 10 and the presence of the partition portion (right side holding wall portion) 21d, the stop claw body 40 and the stop member 50 are held on the slider body 10 in a non-contact state. Therefore, the stop claw body 40 and the stop member 50 can rotate independently of each other. Therefore, even if the stop claw body 40 is rotated upward by the mounting shaft portion 8 of the pull tab 5 as described above, the stop member 50 will not be lifted due to the influence of the rotation of the stop claw body 40, and the stop member 50 can be held at the blocking position.

[0113] Next, by pulling the pull tab 5 to further lift the mounting shaft portion 8, the stop claw body 40 can be rotated significantly upward. As a result, the claw portion 44 of the stop claw body 40 can be withdrawn from the chain tooth guide path 15 of the slider body 10. On the other hand, since the significantly lifted mounting shaft portion 8 not only abuts against the stop claw body 40, but also abuts against the stopper member 50 as shown in Figure 14 it causes the stopper member 50 to rotate upward from the blocking position against the acting force of the leaf spring member 60.

[0114] At this time, as described above, a retreat engagement surface 54b that is linearly inclined obliquely downward is provided in the front half of the stopper base end portion 51 of the stopper member 50 provided in the present embodiment. Therefore, when the stopper member 50 rotates upward while contacting the first support convex portion 21b of the mounting support portion 21, for example, it is different from the case of the operation of installing the pull tab 5 on the slider main body portion 2 (that is, the case where the mounting shaft portion 8 of the pull tab 5 pushes the stopper member 50 forward and rotates the stopper member 50). During the rotation process, the stopper member 50 automatically moves backward, so that the position of the entire stopper member 50 can be moved backward.

[0115] In the present embodiment, by making the stopper member 50 retreat when rotating upward like this, as shown in Figure 14 the left and right tab portions 53b provided on the stopper member 50 can abut against the abutting portion 35 (the second lower end edge 34c of the side wall portion 34) of the cover body 30 from below. As a result, the stopper member 50 cannot rotate upward compared to the position where the tab portion 53b abuts against the cover body 30 and stops. That is, when the pull tab 5 is operated to slide the slider 1, the stopper member 50 cannot rotate to the insertion position where the pull tab insertion gap 16 is significantly opened. As a result, the stopper member 50 blocks at least a part of the pull tab insertion gap 16, and it is possible to prevent the mounting shaft portion 8 of the pull tab 5 from passing through the pull tab insertion gap 16. Therefore, in the slider 1 of the present embodiment, when the pull tab 5 is pulled or the like, it is possible to stably prevent or suppress the pull tab 5 from accidentally (or occasionally) falling off the slider main body portion 2.

[0116] In addition, in the present embodiment, due to the positional relationship between the first support convex portion 21b and the second support convex portion 21c of the slider body 10 and the existence of the partition wall portion (the right holding wall portion) 21d, the stop claw body 40 and the stopper member 50 are stably held in the specified positions, and the rotation actions can be performed independently of each other. Therefore, the automatic stop mechanism of the slider 1 based on the stop claw body 40 can operate stably. In addition, the effects based on the stopper member 50 (that is, the effect of facilitating the pull tab installation operation and the effect of preventing the pull tab 5 from falling off the slider main body portion 2) can be stably obtained.

[0117] In addition, in the slider 1 of the present embodiment, a retracted engagement surface 54b that is linearly inclined obliquely downward toward the front is formed at the stopper base end portion 51 of the stopper member 50 as described above. However, the retracted engagement surface in the present invention may also be formed in a curved shape that is gently curved compared to the curved shape of the claw-side engagement surface 45 of the stop claw body 40, or in a curved shape that is gently curved compared to the curved shape of the curved engagement surface 54a provided on the rear side of the stopper base end portion 51. Here, being gently curved means being curved in such a way that the curvature of the curved portion is smaller than the curvature of the curved portion of the comparison object. Even if the retracted engagement surface formed in such a gently curved manner is provided at the stopper base end portion 51 of the stopper member 50, when the stopper member 50 rotates, the stopper member 50 can move backward while rotating as described above.

[0118] In addition, the slider 1 of the present embodiment is mainly used for a zipper having synthetic resin teeth formed by injection molding. Therefore, as described above, an upper flange portion 13 and a lower flange portion 14 are provided on the slider body 10. However, the slider of the present invention can also be similarly applied to other zippers, such as a zipper having spiral teeth. For example, in that case, the slider of the present invention can also form the slider body without providing one of the upper flange portion 13 and the lower flange portion 14.

Claims

1. A slider for a zipper (1), comprising: a slider body (10) having a tooth guide path (15) formed between an upper wing plate (20) and a lower wing plate (11); a pull tab (5) having a mounting shaft portion (8); a stop pawl body (40) having a pawl portion (44) capable of advancing and retreating relative to the tooth guide path (15); a stopper member (50) arranged side by side with the stop pawl body (40) in the width direction of the slider; and a cover body (30) fixed to the upper wing plate (20) in a cantilever shape. The tooth guide path (15) communicates with left and right shoulder openings provided at the front end portion in the length direction of the slider body (10) and a rear opening provided at the rear end portion in the length direction. The slider is characterized in that a pull tab insertion gap (16) through which the mounting shaft portion (8) of the pull tab (5) can be inserted is provided between the free end portions of the upper wing plate (20) and the cover body (30). The upper wing plate (20) is provided with a mounting support portion (21), and the mounting support portion (21) has support convex portions (21b, 21c) for rotatably supporting the stop pawl body (40) and the stopper member (50). The stop pawl body (40) has a pawl base end portion (41) engaged with the support convex portions (21b, 21c). The pawl base end portion (41) has a pawl side engagement surface (45) that is arc-shaped when the stop pawl body (40) is viewed from the side. The stopper member (50) is supported so as to be rotatable between a passing position for opening the pull tab insertion gap (16) and a blocking position for blocking the pull tab insertion gap (16), and has a shape that can move rearward in the length direction when rotating from the blocking position to the passing position. The stopper member (50) further has a stopper base end portion (51) arranged at the front end portion of the stopper member (50) and engaged with the support convex portions (21b, 21c). On the front half of the surface of the stopper base end portion (51) covering the support convex portions (21b, 21c), a rearward engagement surface (54b) formed in a straight line obliquely downward toward the front is provided when the stopper member (50) is viewed from the side.

2. The slider according to claim 1, characterized in that the stopper member (50) has at least one tab portion (53b) protruding outward in the width direction so as to be able to interfere with the cover body (30).

3. The slider according to claim 2, characterized in that the cover body (30) has: an abutting portion (35) that abuts against the tab portion (53b) when the stopper member (50) rotates from the blocking position to the passing position to stop the rotation of the stopper member (50); and a receiving space portion (36) that receives the tab portion (53b) when the stopper member (50) rotates from the blocking position to the passing position to allow the stopper member (50) to rotate to the passing position by a larger amplitude compared to the state of abutting against the abutting portion (35). The accommodation space portion (36) of the cover body (30) is disposed on the front side in the slider length direction compared to the abutting portion (35).

4. The slider according to any one of claims 1 to 3, characterized in that the straight retreat engagement surface (54b) is inclined at an angle (θ) of 20° or more and 70° or less with respect to the slider length direction when the stopper member (50) is viewed from the side.

5. The slider according to any one of claims 1 to 3, characterized in that the support convex portions (21b, 21c) of the mounting support portion (21) have a first support convex portion (21b) that rotatably supports the stop claw body (40) and a second support convex portion (21c) that rotatably supports the stopper member (50), the second support convex portion (21c) is disposed on the front side or the rear side in the slider length direction compared to the first support convex portion (21b).

6. The slider according to claim 4, characterized in that the support convex portions (21b, 21c) of the mounting support portion (21) have a first support convex portion (21b) that rotatably supports the stop claw body (40) and a second support convex portion (21c) that rotatably supports the stopper member (50), the second support convex portion (21c) is disposed on the front side or the rear side in the slider length direction compared to the first support convex portion (21b).

7. The slider according to claim 5, characterized in that a partition wall portion (21d) extending rearward from the first support convex portion (21b) and the second support convex portion (21c) is provided at a position between the first support convex portion (21b) and the second support convex portion (21c).

8. The slider according to claim 6, characterized in that a partition wall portion (21d) extending rearward from the first support convex portion (21b) and the second support convex portion (21c) is provided at a position between the first support convex portion (21b) and the second support convex portion (21c).

9. The slider according to any one of claims 1 to 3, characterized in that the stopper base end portion (51) has a wide-width portion (55) and a narrow-width portion (56) that is disposed rearward compared to the wide-width portion (55) and is thinner than the wide-width portion (55) in the slider width direction, the mounting support portion (21) has a pair of holding wall portions (21d) extending rearward from the support convex portion (21c) that supports the stopper member (50) and a receiving gap formed between the pair of holding wall portions (21d) for receiving the narrow-width portion (56).
