The present invention relates to a slider structure and slider connector used in an adjustable zipper that adjusts the dimensions of specific parts of clothing, such as the abdomen or sleeves.

Double-slider zippers that adjust the degree to which a specific portion of an article is rolled up are known (see Patent Document 1). A double-slider zipper comprises first and second sliders through which two tape element rows are inserted, and an auxiliary connector that connects the first and second sliders. A belt connects the auxiliary connector and the specific portion of the article. The auxiliary connector comprises a connection base (base member) that houses the first and second sliders from below, and a connection cover (cover member) that engages with the connection base and presses the first and second sliders from above. This double-slider zipper slides when the pull tab on the first slider is operated, rolling up the specific portion of the article.

China Utility Model No. 209235120

However, when the double slider zipper described in Patent Document 1 is operated, there is a risk that the first and second sliders may come off the connection base, and as a result, the connection cover may come off. For this reason, it is desirable to maintain the state in which the first and second sliders are held by the connection base even in the above-mentioned cases.

The object of the present invention is to provide a slider structure and slider linkage that can maintain the holding state of the first slider and second slider.

The slider structure of the present invention comprises a first slider and a second slider that engage and separate element rows arranged along a pair of tapes, and a slider connecting body that connects the first slider and the second slider facing each other, the first slider having a connecting portion that protrudes upward and has a top surface and a side surface, and a pull tab that can be operated to slide along the pair of tapes is connected to the connecting portion, the slider connecting body comprises a base member that holds the first slider and the second slider, and a cover member that engages with the base member and covers at least a portion of the first slider and the second slider from above, the base member having a base bottom plate portion, a first pressing portion that rises from the base bottom plate portion and presses the first slider from above, and a second pressing portion that rises from the base bottom plate portion and presses the second slider from above.
According to the slider structure of the present invention, the base member has a base bottom plate portion, a first pressing portion, and a second pressing portion, so that the risk of the first slider and the second slider coming off when operating the slider structure can be reduced, and the first slider and the second slider can be maintained in a held state.

In the slider structure of the present invention, the base member may have a first reinforcing portion that is arranged adjacent to the first pressing portion in a direction along the base bottom plate portion and that is continuous with the base bottom plate portion and the first pressing portion.
With this configuration, the base member has the aforementioned first reinforcing portion that connects the base bottom plate portion and the first holding portion, which improves the connection strength between the base bottom plate portion and the first holding portion compared to a case where the base member does not have the first reinforcing portion. Therefore, even if a twisting force is applied to the slider connector during operation of the slider structure, the risk of the first holding portion becoming misaligned with respect to the first slider can be reduced, and the first slider can be firmly maintained in a held state.

In the slider structure of the present invention, the base member may have a second reinforcing portion that is arranged adjacent to the second pressing portion in a direction along the base bottom plate portion and that is continuous with the base bottom plate portion and the second pressing portion.
With this configuration, the base member has the aforementioned second reinforcing portion that connects the base bottom plate portion and the second holding portion, which improves the connection strength between the base bottom plate portion and the second holding portion compared to a case where the second reinforcing portion is not included. Therefore, even if a twisting force is applied to the slider connecting body during operation of the slider structure, the risk of the second holding portion becoming misaligned with respect to the second slider can be reduced, and the second slider can be firmly maintained in a held state.

In the slider structure of the present invention, the cover member may be configured to press at least a portion of the top surface and a portion of the side surface of the connecting portion of the first slider.
With this configuration, even if an external force is applied to the connecting portion of the first slider, for example by twisting the pull tab, the aforementioned cover member presses not only part of the top surface of the connecting portion but also part of the side surface, thereby suppressing the mutual rocking of the first slider and the cover member and reducing the risk of the cover member shifting from its predetermined position relative to the first slider.

In the slider structure of the present invention, the engagement position between the base member and the cover member in the vertical direction may be positioned at the same position as or lower than the pressing position where the first pressing portion and the second pressing portion press the first slider and the second slider from above.
With this configuration, foreign matter is less likely to get caught in the engagement portion between the cover member and the base member compared to when the engagement position between the base member and the cover member in the vertical direction is positioned above the aforementioned pressing position, thereby reducing the risk of the cover member and the base member becoming disengaged.

In the slider structure of the present invention, the base member has a pair of base side plate portions raised upward from both side edges of the base bottom plate portion, the first pressing portion is arranged on one end side of the base side plate portions, and the second pressing portion is arranged on the other end side of the base side plate portions, and the engagement position between the base member and the cover member in the vertical direction may be arranged at the same position as the upper edge of the base side plate portions or at a position lower than that.
With this configuration, the aforementioned engagement position is positioned at the same position as or lower than the upper edge of the base side plate portion in the vertical direction, making it less likely for foreign matter to get caught in the engagement portion between the cover member and the base member, thereby further reducing the risk of the cover member and the base member becoming disengaged.

In the slider structure of the present invention, the first pressing portion and the second pressing portion each have a pressing surface that abuts against the first slider and the second slider from above, and the base member has an engagement surface that engages with the cover member in the vertical direction, and the position of the engagement surface may be positioned at the same position as the position of the pressing surface or lower.
With this configuration, the position (vertical position) of the engagement surface on the base member can be set as described above relative to the position (vertical position) of the pressing surface, and the engagement position in the vertical direction between the base member and the cover member can be easily set to the same position as the pressing position described above or a position lower than that.

In the slider structure of the present invention, the cover member has a cover engagement portion consisting of a pair of engagement claws facing each other in a left-right direction that intersects the up-down direction, and the base member has a base engagement portion having a pair of the engagement surfaces in the left-right direction and a pair of guide surfaces located above each of the engagement surfaces, and the engagement claws engage with the engagement surfaces in the up-down direction, and the pair of guide surfaces may be configured to gradually widen from each other in the left-right direction as they move downward.
With this configuration, by pressing the cover member against the base member from above, the pair of engaging claws are gradually pushed apart to the left and right while being guided by the pair of guide surfaces, and when the pair of engaging claws move downward over the pair of guide surfaces and engage with the pair of engaging surfaces, they return to their original position, allowing the pair of engaging claws to engage with the pair of engaging surfaces. In this way, the cover engaging portion can be smoothly engaged with the base engaging portion.

In the slider structure of the present invention, the base engagement portion has a pair of auxiliary guide surfaces that are arranged adjacent to the pair of guide surfaces on the second slider side in a longitudinal direction that intersects the up-down and left-right directions, and the pair of auxiliary guide surfaces may be configured to gradually widen from each other in the left-right direction as they approach the second slider side.
With this configuration, when the cover engagement portion is pushed into the base engagement portion, the pair of engagement claws can be auxiliary guided toward the pair of guide surfaces in the longitudinal direction, allowing the cover engagement portion to smoothly engage with the base engagement portion.

In the slider structure of the present invention, the base engagement portion may be configured as an engagement pillar further having a restriction surface that restricts movement of the pair of engagement claws in an engaged state toward the second slider side.
With this configuration, by engaging the cover engagement portion with the base engagement portion, the movement of the cover member toward the second slider can be restricted by the restricting surface. Therefore, there is no need to provide a structure to restrict this movement other than the engagement pillar, and the configuration of the slider structure can be simplified.

In the slider structure of the present invention, the second slider may be formed with a protruding portion that protrudes upward, and the cover member may cover the protruding portion.
With this configuration, the cover member covers the protruding parts such as the connecting part of the second slider, so that, for example, by twisting the pull tab, an external force is applied to the connecting part of the first slider, and as a result, even if the cover member tries to swing, the swinging of the cover member can be more effectively suppressed, making it less likely for the cover member to shift out of position relative to the first slider and the second slider.

The slider structure of the present invention may be configured such that the first slider is attached to the connecting portion and includes a locking member having an engaging tip that can engage with the element row and can protrude into and retract from the insertion passage of the first slider, and the pull tab abuts against the locking member when pulled, and the engaging tip that protrudes into the insertion passage is retracted into the insertion passage.
According to this configuration, a so-called lock slider can be configured in which the lock member is operated by pulling the aforementioned pull tab.

In the slider structure of the present invention, the base member may have a first holding portion having the first pressing portion and holding the first slider, a second holding portion having the second pressing portion and holding the second slider, and a base engagement portion disposed between the first holding portion and the second holding portion, and the cover member may have a first cover portion that covers and holds at least a portion of the top surface and a portion of the side surface of the connecting portion of the first slider from above, a second cover portion that covers at least a portion of the second slider from above, and a cover engagement portion that is disposed between the first cover portion and the second cover portion and engages with the base engagement portion.

The slider assembly of the present invention includes the base member of the slider structure of the present invention described above, and the cover member of the slider structure of the present invention described above that engages with the base member.
According to the slider structure of the present invention, it is possible to form a slider assembly that can achieve the same effects as those of the present invention described above.

The present invention provides a slider structure and slider assembly that reduce the risk of the cover member coming off its predetermined position relative to the first slider.

[Configuration of this embodiment]
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
1 to 4, the slider structure 1 of this embodiment includes a first slider 10 (fastener slider) and a second slider 20 (fastener slider) that are slidable to engage and separate element rows (fastener element rows) composed of coil elements or the like arranged along a pair of tapes (fastener tapes), and a slider connector 30 that connects the first slider 10 and the second slider 20 facing each other.
In the following description, the X direction is the sliding movement direction (length direction) of the slider structure 1, the Y direction perpendicular to the X direction is the left-right direction (width direction) of the slider structure 1, and the Z direction perpendicular to the X and Y directions is the up-down direction (thickness direction) of the slider structure.

In this embodiment, the slider structure 1 is used in an adjustable zipper that adjusts the dimensions of the abdomen, sleeves, and other areas of clothing. The adjustable zipper is composed of a pair of tapes with the aforementioned element array and the slider structure 1. In an example of how the adjustable zipper is used, the aforementioned tape is sewn to clothing, the aforementioned element array and the base member 40 of the slider structure 1 (described below) are placed on the back side of the clothing, and the first slider 10 and second slider 20 are slidably fitted to the element array on the back side of the clothing. The pull tab 18 and cover member 60 (described below) of the slider structure 1 are placed on the front side of the clothing, and the string hole 411 (described below) is connected to a string-like body for adjusting the dimensions of specific areas of the clothing, such as the abdomen or sleeves.

As shown in Figure 2, the first slider 10 includes a slider body 11 through which each element row can be inserted from the rear opening 10B to the shoulder opening 10A, and a pull tab 18 that slides the slider body 11 in the X direction along a pair of tapes.

The slider body 11 is made of the same material and is integrally formed with an upper plate 12, a lower plate 13, a column 14 connecting the upper plate 12 and the lower plate 13, and a connecting portion 15 to which a pull tab 18 is connected. A lock pin 16 is attached to the connecting portion 15 as a locking member.

The lower plate portion 13 has a plate-shaped lower plate main body portion 131 and side plate portions 132 that extend upward from both side edges of the lower plate main body portion 131 in the Y direction.

The pillar portion 14 extends upward from a position near the shoulder 10A in the X direction of the lower plate main body portion 131 and approximately in the center in the Y direction.

The upper plate portion 12 has a plate-shaped upper plate main body portion 121 formed on the top of the column portion 14, and flange portions 122 extending inward in the Y direction from each of the side plate portions 132 on both sides in the Y direction. In this embodiment, the upper plate main body portion 121 and the flange portions 122 are formed separately from each other, and are configured so that the tape can pass between them.

The connecting portion 15 has a first connecting protrusion 151 and a second connecting protrusion 152 that protrude upward from the upper plate main body portion 121. The first connecting protrusion 151 and the second connecting protrusion 152 are spaced apart in the X direction, with the first connecting protrusion 151 located on the shoulder opening 10A side and the second connecting protrusion 152 located on the rear opening 10B side. The first connecting protrusion 151 has an upper surface 153 and a pair of left and right side surfaces 154 that are continuous with the upper surface 153.

The lock pin 16 is positioned across the first connecting protrusion 151 and the second connecting protrusion 152, and has a hole (not shown) formed in the upper plate main body 121 on the side facing the second connecting protrusion 152. An engaging tip (not shown) is positioned in this hole, capable of retracting into the insertion passage 17 through which the element row is inserted. This engaging tip engages with the element row when protruding into the insertion passage 17 (when inserted into the hole described above), and releases the engagement when retracted into the insertion passage 17 of the upper plate main body 121. In this engaged state, the slider structure 1 cannot slide along the pair of tapes, and is able to slide when disengaged.

The pull tab 18 has a pull tab main body 181 and a pull tab shaft 183 formed at one end of the pull tab main body 181. The pull tab shaft 183 is rotatably connected to the connecting portion 15. The pull tab shaft 183 is disposed between the first connecting protrusion 151 and the second connecting protrusion 152.
When a pulling force is applied to the pull tab body 181 by operation, the pull tab shaft 183 abuts against the lock pin 16, causing it to elastically deform, causing the engaging tip of the lock pin 16 to sink into the hole in the upper plate 12, releasing the engagement between the engaging tip and the element row, thereby entering a released state. In the released state, the slider structure 1 is able to slide along the pair of tapes, and the sliding movement of the slider structure 1 makes it possible to adjust the dimensions of the garment, such as around the abdomen or sleeves.
Furthermore, when the operation is completed and the aforementioned pulling force is no longer applied to the pull tab main body 181, the lock pin 16 that has been elastically deformed by the pull tab shaft 183 returns to its original shape, and the engaging tip of the lock pin 16 protrudes from the hole in the upper plate 12 into the insertion passage 17 and enters an engaged state in which it engages with the element row. In the engaged state, the slider structure 1 is unable to slide along the pair of tapes, and the dimensions of the garment, such as the abdominal circumference and sleeve circumference, are determined.

In this embodiment, the first slider 10 is a so-called lock slider that has a locking mechanism formed by the lock pin 16, but it may also be a normal slider that does not have a locking mechanism and does not have a locking pin 16.

The second slider 20 has a slider body 21 formed in substantially the same manner as the slider body 11 except for the connecting portion 15, but differs from the first slider 10 in that it does not have components corresponding to the lock pin 16 and the pull tab 18. Note that the components of the slider body 21 that are the same as those of the slider body 11 are appropriately designated by the same reference numerals and detailed description thereof will be omitted.
A connecting portion 25 is formed on the upper surface of the upper plate main body portion 121 of the slider body 21 as a protrusion that protrudes upward. This connecting portion 25 is composed of a pair of connecting protrusions 251 spaced apart in the X direction. In the slider structure 1, a component equivalent to a pull tab is not connected to the connecting portion 25, but if a component equivalent to the pull tab 18 is connected to the connecting portion 25 and the second slider 20 is used alone as a fastener slider, the connection can be made by crimping the pair of connecting protrusions 251.

The shoulder openings 10A of the slider bodies 11, 21 are positioned opposite each other in the X direction, and the rear openings 10B are positioned further apart in the X direction than the shoulder openings 10A. Therefore, the element rows inserted through the insertion passages 17 from the rear opening 10B of one of the slider bodies 11, 21 are separated left and right in the Y direction by the pillar portions 14, and the element rows delivered from the rear opening 10B of the other slider body 11, 21 are interlocked with each other.

The slider assembly 30 includes a base member 40 that holds the first slider 10 and the second slider 20, and a cover member 60 that engages with the base member 40 and covers at least a portion of the first slider 10 and the second slider 20 from above.
Although the first slider 10 and the second slider 20 are made of metal in this embodiment, they may be made of other materials such as synthetic resin.

The base member 40 includes a base bottom plate 41 having a string-threading hole 411 formed at one end in the X direction through which a string-like object (not shown) is threaded and connected; base side plate portions 42 extending upward from both X-direction edges of the base bottom plate 41; left and right first presser portions 43 extending from the base bottom plate 41 and positioned at one end of the base side plate 42 in the X direction, and pressing down on the first slider 10 from above; left and right second presser portions 44 extending from the base bottom plate 41 and positioned at the other end of the base side plate 42 in the X direction, and pressing down on the second slider 20 from above; and a base engagement portion 51 consisting of an engagement post 45A protruding upward from approximately the center of the base bottom plate 41 in the X direction. In this embodiment, the string-like object threaded through the string-threading hole 411 is used to adjust the dimensions of the garment, such as the abdomen and sleeves.

The base member 40 further includes a first reinforcing portion 49 that is positioned adjacent to the first pressing portion 43 in the direction along the base bottom plate portion 41 (directions along the plane of the X and Y directions) and that connects the base bottom plate portion 41 and the first pressing portion 43, and a second reinforcing portion 48 that is positioned adjacent to the second pressing portion 44 in the direction along the base bottom plate portion 41 and that connects the base bottom plate portion 41 and the second pressing portion 44. These first reinforcing portion 49 and second reinforcing portion 48 reinforce the first pressing portion 43 and second pressing portion 44.

The first reinforcing portion 49 is positioned adjacent to one end of the base member 40 in the X direction (the string hole 411 side) relative to each first pressing portion 43. The dimension of the first reinforcing portion in the X direction gradually increases from top to bottom, which increases the continuous area with the base bottom plate portion 41 and further reinforces the first pressing portion 43. The first reinforcing portion 49 and the base bottom plate portion 41 form a substantially L-shaped cross section.

The second reinforcing portion 48 is located at the other end of the base member 40 in the X direction and is formed in the shape of an end plate. The second reinforcing portion 48, which rises from the base bottom plate portion 41, is positioned between the left and right second pressing portions 44 and is continuous with them, thereby further reinforcing the second reinforcing portion 48. The second reinforcing portion 48 and the base bottom plate portion 41 form a substantially L-shaped cross section.

The portion of the base member 40 closer to one end in the X direction than the base engagement portion 51 is configured as a first holding portion 45 that holds the first slider 10. The portion of the base member 40 closer to the other end in the X direction than the base engagement portion 51 is configured as a second holding portion 46 that holds the second slider 20. The first holding portion 45 has a first pressing portion 43, and the second holding portion 46 has a second pressing portion 44. The base engagement portion 51 is disposed between the first holding portion 45 and the second holding portion 46.

In the first holding portion 45, the base bottom plate portion 41 and a pair of base side plate portions 42 cover the lower plate main body portion 131 and side plate portions 132 of the slider body 11, and the pressing surface 431, which is the underside of the first pressing portion 43, abuts from above and presses down the portion of the upper surface of the flange portion 122, which constitutes part of the upper plate portion 12 of the slider body 11, near the rear opening 10B.

In the second holding portion 46, the base bottom plate portion 41 and a pair of base side plate portions 42 cover the lower plate main body portion 131 and side plate portions 132 of the slider body 21, and the pressing surface 441, which is the underside of the second pressing portion 44, abuts from above and presses down the portion of the upper surface of the flange portion 122, which constitutes part of the upper plate portion 12 of the slider body 21, near the rear opening 10B.

As shown in Figures 4 to 7, the base engagement portion 51 has a pair of left and right engagement surfaces 52 formed on the tip portion 451 of the engagement post 45A facing the first holding portion 45; a pair of left and right guide surfaces 53 arranged above the pair of left and right engagement surfaces 52; and a pair of left and right auxiliary guide surfaces 54 continuous with the pair of left and right guide surfaces 53 and arranged on the second holding portion 46 side of the pair of left and right guide surfaces 53. The base engagement portion 51 also has a restriction surface 55 that restricts movement of a pair of engagement claws 67 (described below) in the X direction toward the second slider 20 when engaged. The restriction surface 55 is formed on the surface of the engagement post 45A facing the second holding portion 46 and extends in the Y and Z directions. The restriction surface 55 is arranged on the second holding portion 46 side of the engagement surface 52.

The pair of left and right engagement surfaces 52 are formed as surfaces extending in the X and Y directions. The positions of the pair of left and right engagement surfaces 52 are the same as or lower than the positions of the pressing surfaces 431, 441 in the Z direction. Therefore, the engagement position at which the cover member 60 engages with the engagement surfaces 52 is the same as or lower than the positions at which the first pressing portion 43 and the second pressing portion 44 press the upper plate portions 12 of the first slider 10 and the second slider 20, respectively. Furthermore, the position of the engagement surfaces 52 in the Z direction (the aforementioned engagement positions) is the same as or lower than the upper edge of at least portions of the base side plate portion 42 located on both sides of the engagement surfaces 52 in the Y direction. In this embodiment, the upper edge of the base side plate portion 42 is aligned in the X direction, and the aforementioned engagement positions are located at the same positions in the Z direction as this upper edge.

The pair of left and right guide surfaces 53 are configured as inclined surfaces that gradually widen in the Y direction as they extend downward from the top surface 452 of the engagement post 45A. The pair of left and right auxiliary guide surfaces 54 are each positioned adjacent to the pair of left and right guide surfaces 53 on the second slider 20 side (second holding portion 46 side), and are configured as inclined surfaces that gradually widen in the Y direction as they extend from the pair of left and right guide surfaces 53 toward the second slider 20 side. In addition, the pair of left and right auxiliary guide surfaces 54 are inclined obliquely upward as they extend from the first slider 10 side (first holding portion 45 side) toward the second slider 20 side (second holding portion 46 side).

The cover member 60 has a first cover part 61 that covers and presses at least a portion of the upper surface 153 and a portion of the pair of side surfaces 154 of the connecting portion 15 of the first slider 10 from above, a second cover part 62 that covers at least a portion of the connecting portion 25 of the second slider 20 from above, and a cover engagement part 63 that is positioned between the first cover part 61 and the second cover part 62 and engages with the base engagement part 51.

The cover member 60 also has an upper portion 65 aligned along the X direction and a pair of left and right side portions 66 continuous with the upper portion 65 along the X direction. The cover engagement portion 63 is composed of a pair of left and right engagement claws 67 extending downward from the pair of left and right side portions 66. As shown in FIG. 4 , the engagement claws 67 each have a lower tip claw portion 671 extending inward in the Y-axis direction. The upper surface of the tip claw portion 671 forms an engagement surface 672, which engages with the engagement surface 52 of the base engagement portion 51 in the Z-direction. The tip claw portion 671 is formed with a guided surface 673 that slopes obliquely upward as it extends inward in the Y-direction. This inclination of the guided surface 673 allows the guided surface 673 to be smoothly guided by the guide surface 53 of the base engagement portion 51. Furthermore, because the engagement claws 67 engage with the regulating surface 55 on the side of the second slider 20 in the X direction, movement of the cover member 60 toward the other end in the X direction is restricted by the regulating surface 55. Furthermore, movement of the cover member 60 toward one end in the X direction is restricted by the connecting portion 25 of the second slider 20.

The first cover part 61 is composed of an upper part 65 and a pair of side parts 66 located closer to the first slider 10 than the engagement claw 67, and the second cover part 62 is composed of an upper part 65 and a pair of side parts 66 located closer to the second slider 20 than the engagement claw 67. Therefore, when the cover engagement part 63 is engaged with the base engagement part 51, the upper part 65 and pair of side parts 66 that constitute the first cover part 61 cover at least a portion of the upper surface 153 and pair of side parts 154 of the first connecting protrusion 151 on the first slider 10, as shown in FIG. 3, for example, and the upper part 65 and pair of side parts 66 that constitute the second cover part 62 cover the connecting part 25 on the second slider 20.

In the slider structure 1 described above, the procedure for attaching the cover member 60 to the base member 40 is as follows.

First, as shown in Figure 8, the cover engagement portion 63 of the cover member 60 is pressed against the base engagement portion 51 of the base member 40 from above, while the second cover portion 62 covers the connecting portion 25 of the second slider 20.

Next, by pushing the cover member 60 further downward, the pair of left and right engagement claws 67 are pushed open outward in the Y direction while being guided by the pair of left and right guide surfaces 53 of the base engagement portion 51. At this time, even if the engagement claws 67 engage with the pair of left and right auxiliary guide surfaces 54, the engagement claws 67 are guided toward the guide surfaces 53 by the auxiliary guide surfaces 54.

Next, by pushing the cover member 60 further downward, the pair of left and right engagement claws 67 clear the pair of left and right guide surfaces 53, and the engagement surface 672 of the tip claw portion 671 is positioned below the engagement surface 52 of the base engagement portion 51, causing the engagement claws 67 to return to their original state while the engagement surface 672 engages with the engagement surface 52 in the Z direction.

At this time, as described above, the engagement position between the cover engagement portion 63 and the base engagement portion 51 is either the same as the position in the Z direction where the first and second holding portions 43 and 44 hold down the first and second sliders 10 and 20, respectively, or a position below this position. Therefore, compared to when the engagement position is above the holding position, as described above, the slider structure 1 can be configured so that foreign matter is less likely to get caught on the cover engagement portion 63, reducing the risk of the cover member 60 becoming detached from the base member 40 due to foreign matter getting caught.

Furthermore, when the cover member 60 and base member 40 are engaged, the first cover portion 61 covers and presses against the upper surface 153 and a portion of the pair of side surfaces 154 of the first connecting protrusion 151 of the first slider 10. Therefore, even if an external force is applied to the connecting portion 15 of the first slider 10 by twisting the pull tab 18, the cover member 60 presses against not only a portion of the upper surface 153 of the connecting portion 15 but also a portion of the pair of side surfaces 154, thereby preventing the first slider 10 and cover member 60 from swinging relative to each other and reducing the risk of the cover member 60 shifting from its predetermined position relative to the first slider 10.

[Modification]
In the above embodiment, the engagement position between the cover engaging portion 63 and the base engaging portion 51 is located at the same position as or below the pressing position in the Z direction where the first pressing portion 43 and the second pressing portion 44 press the top plate portion 12 of the first slider 10 and the second slider 20, but may be located above the pressing position if the cover member 60 is configured to be less likely to come off the base member 40 due to getting caught on foreign matter or the like. Also, the above-mentioned engagement position may be located at the same position as or below the position of the top surface of the top plate portion 12 of the first slider 10 or the second slider 20 in the Z direction, in which case foreign matter or the like can be made less likely to get caught on the engagement portion, making it more difficult for the engagement between the cover engaging portion 63 and the base engaging portion 51 to come off.

In the above embodiment, the position of the engagement surface 52 in the Z direction (the engagement position described above) is located at the same position as or below the upper edge of the base side plate portion 42, but as described above, if the cover member 60 is configured to be less likely to come off the base member 40 due to getting caught on foreign matter, etc., it may be located above the upper edge of the base side plate portion 42.

In the above embodiment, the base engagement portion 51 is provided with a pair of guide surfaces 53 that gradually widen in the Y direction as they extend downward, and a pair of auxiliary guide surfaces 54 that gradually widen in the Y direction as they extend toward the second slider 20, allowing for smoother engagement with the cover engagement portion 63. However, the base engagement portion 51 can be configured to engage with the cover engagement portion 63 even without the pair of guide surfaces 53 or pair of auxiliary guide surfaces 54, and therefore the pair of guide surfaces 53 and pair of auxiliary guide surfaces 54 may be omitted. Furthermore, if the pair of guide surfaces 53 or other components are omitted, the guided surface 673 of the engagement claw 67 may be retained or omitted.

In the above embodiment, the second slider is formed with a connecting portion 25, but this configuration may be omitted.

In the above embodiment, the cover member 60 is configured to press at least a portion of the top surface 153 and a portion of the pair of side surfaces 154 of the connecting portion 15 of the first slider 10, thereby reducing the risk of the cover member 60 shifting from its predetermined position relative to the first slider 10 when, for example, the pull tab 18 is twisted. However, if the primary objective is to reduce the likelihood of the cover member 60 becoming detached from the base member 40 due to getting caught on a foreign object or the like, the engagement position between the cover engagement portion 63 and the base engagement portion 51 may be positioned at the same position as or lower than the pressing position in the Z direction where the first pressing portion 43 and the second pressing portion 44 press against the top plate portion 12 of the first slider 10 and the second slider 20, and the cover member 60 may be configured not to press against the top surface 153 or the side surfaces 154 of the connecting portion 15 of the first slider 10.
