Disclosure of Invention

However, in the case of operating the double slider slide fastener described in patent document 1, there is a possibility that the 1 st slider and the 2 nd slider come off from the connection base, and the connection cover comes off accordingly. Therefore, it is desirable to maintain the holding state of the connection base with respect to the 1 st slider and the 2 nd slider even in the above-described case.

The utility model aims to provide a pull head structure and a pull head connecting body capable of maintaining the holding state of a 1 st pull head and a 2 nd pull head.

A slider structure of the present utility model includes: a 1 st slider and a 2 nd slider for engaging and disengaging element rows provided along a pair of tapes; and a slider connecting body for connecting the 1 st slider and the 2 nd slider to each other, wherein a connecting portion having an upper surface and a side surface and formed so as to protrude upward is formed on the 1 st slider, and a slider capable of performing a sliding movement operation along the pair of tapes is connected to the connecting portion, the slider connecting body comprising: a base member that holds the 1 st slider and the 2 nd slider; and a cover member that engages with the base member and covers at least a part of the 1 st slider and the 2 nd slider from above, the base member including: a base bottom plate portion; a 1 st pressing portion that stands up from the base bottom plate portion and presses the 1 st slider from above; and a 2 nd pressing portion that stands up from the base bottom plate portion and presses the 2 nd slider from above.

According to the slider structure of the present utility model, since the base member has the base bottom plate portion and the 1 st pressing portion and the 2 nd pressing portion, the possibility of the 1 st slider and the 2 nd slider coming off can be reduced when the slider structure is operated, and the holding state of the 1 st slider and the 2 nd slider can be maintained.

In the slider structure of the present utility model, the base member may have a 1 st reinforcing portion, the 1 st reinforcing portion may be disposed adjacent to the 1 st pressing portion in a direction along the base bottom plate portion, and may connect the base bottom plate portion and the 1 st pressing portion.

According to such a configuration, since the base member has the 1 st reinforcing portion described above that connects the base bottom plate portion and the 1 st pressing portion, the connection strength between the base bottom plate portion and the 1 st pressing portion can be improved as compared with the case where the 1 st reinforcing portion is not provided. Therefore, even if a torsion force is applied to the slider connecting body when the slider structure is operated, the possibility of the 1 st pressing portion being displaced relative to the 1 st hair-pulling head can be reduced, and the holding state of the 1 st slider can be firmly maintained.

In the slider structure of the present utility model, the base member may have a 2 nd reinforcing portion which is disposed adjacent to the 2 nd pressing portion in a direction along the base bottom plate portion and connects the base bottom plate portion and the 2 nd pressing portion.

According to such a configuration, since the base member has the 2 nd reinforcing portion described above that connects the base bottom plate portion and the 2 nd pressing portion, the connection strength between the base bottom plate portion and the 2 nd pressing portion can be improved as compared with the case where the 2 nd reinforcing portion is not provided. Therefore, even if a torsion force is applied to the slider connecting body when the slider structure is operated, the possibility of the 2 nd pressing portion being displaced relative to the 2 nd hair-pulling head can be reduced, and the holding state of the 2 nd slider can be firmly maintained.

In the slider structure of the present utility model, the cover member may be configured to press at least a part of the upper surface and a part of the side surface of the coupling portion of the 1 st slider.

According to such a configuration, even if an external force is applied to the coupling portion of the 1 st slider by twisting the tab, for example, the cover member presses not only a part of the upper surface but also a part of the side surface of the coupling portion, so that the 1 st slider and the cover member can be prevented from being moved relative to each other, and the possibility that the cover member is deviated from the predetermined position with respect to the 1 st slider can be reduced.

In the slider structure of the present utility model, the engagement position between the base member and the cover member in the up-down direction may be arranged at the same position as or at a position lower than the pressing position at which the 1 st pressing portion and the 2 nd pressing portion press the 1 st slider and the 2 nd slider from above.

According to this configuration, the foreign matter is less likely to be caught by the engaging portion between the cover member and the base member than in the case where the engaging position between the base member and the cover member in the up-down direction is arranged above the pressing position, and therefore, the possibility of the cover member being disengaged from the base member can be reduced.

In the slider structure of the present utility model, the base member may have a pair of base side plate portions rising upward from both side edges of the base bottom plate portion, the 1 st pressing portion may be disposed on one end side of the base side plate portion, the 2 nd pressing portion may be disposed on the other end side of the base side plate portion, and an engagement position between the base member and the cover member in the up-down direction may be disposed at the same position as or at a position lower than an upper edge of the base side plate portion.

According to this configuration, since the engagement position is arranged at the same position as or lower than the upper edge of the base side plate portion in the vertical direction, it is possible to form a structure in which foreign matter is less likely to be engaged with the engagement portion between the cover member and the base member, and thus it is possible to reduce the possibility of disengagement of the engagement between the cover member and the base member.

In the slider structure of the present utility model, the 1 st pressing portion and the 2 nd pressing portion may have pressing surfaces that are in contact with the 1 st slider and the 2 nd slider from above, respectively, and the base member may have engagement surfaces that engage with the cover member in the up-down direction, and the engagement surfaces may be disposed at the same position as or at a position lower than the pressing surfaces.

According to this configuration, the position (vertical position) of the engagement surface with respect to the position (vertical position) of the pressing surface in the base member is set as described above, and therefore the engagement position in the vertical direction of the base member and the cover member can be easily set to the same position as the pressing position or a position lower than the pressing position.

In the slider structure of the present utility model, the cover member may have a cover engaging portion including a pair of engaging claws facing each other in a left-right direction intersecting the up-down direction, and the base member may have a base engaging portion including: a pair of engagement surfaces in the left-right direction; and a pair of guide surfaces located above the engagement surfaces, respectively, the engagement claws being engaged with the engagement surfaces in the up-down direction, the pair of guide surfaces being configured to gradually widen in the left-right direction as going downward.

According to this configuration, the cover member is pressed against the base member from above, and the pair of engagement claws are gradually pushed away leftward and rightward while being guided along the pair of guide surfaces, and the pair of engagement claws pass downward over the pair of guide surfaces and recover when engaged with the pair of engagement surfaces, whereby the pair of engagement claws can be engaged with the pair of engagement surfaces. In this way, the cover engaging portion and the base engaging portion can be smoothly engaged.

In the slider structure of the present utility model, the base engagement portion may have a pair of auxiliary guide surfaces disposed adjacent to the pair of guide surfaces on the 2 nd slider side in a longitudinal direction intersecting the vertical direction and the horizontal direction, and the pair of auxiliary guide surfaces may be configured to gradually widen in the horizontal direction toward the 2 nd slider side.

According to this configuration, when the cover engaging portion is pushed into the base engaging portion, the pair of engaging claws can be guided to the pair of guide surfaces in the longitudinal direction with assistance, and the cover engaging portion and the base engaging portion can be smoothly engaged.

In the slider structure of the present utility model, the base engaging portion may include an engaging column having a pair of engaging claws for restricting the engaged state from moving toward the 2 nd slider side.

According to this configuration, since the cover member can be restricted from moving to the 2 nd slider by the restricting surface by engaging the cover engaging portion with the base engaging portion, it is unnecessary to have a structure for restricting the movement in addition to the engaging post, and the structure of the slider structure can be simplified.

In the slider structure of the present utility model, a protruding portion protruding upward may be formed in the 2 nd slider, and the cover member may cover the protruding portion.

According to this configuration, since the cover member covers the protruding portion such as the coupling portion of the 2 nd slider, even if an external force is applied to the coupling portion of the 1 st slider, for example, by twisting the tab, the shaking of the cover member can be further suppressed, and the cover member is less likely to be displaced from the 1 st slider and the 2 nd slider.

In the slider structure of the present utility model, the 1 st slider may have a locking member attached to the coupling portion, the engagement tip capable of engaging with the element row may be moved out and into engagement with the insertion path of the 1 st slider, and the pull tab may be configured to abut against the locking member by a pulling operation thereof, and the engagement tip in a state protruding from the insertion path may be moved into a state of being moved into engagement with the insertion path.

According to this configuration, the so-called lock slider in which the lock member is operated by the pulling operation of the pull tab can be formed.

In the slider structure of the present utility model, the base member may include: a 1 st holding portion that has the 1 st pressing portion and holds the 1 st slider; a 2 nd holding portion that has the 2 nd pressing portion and holds the 2 nd slider; and a base engagement portion disposed between the 1 st holding portion and the 2 nd holding portion, the cover member including: a 1 st cover part which covers and presses at least a part of the upper surface and a part of the side surface of the connection part of the 1 st slider from above; a 2 nd cover part covering at least a part of the 2 nd slider from above; and a cover engagement portion which is disposed between the 1 st cover portion and the 2 nd cover portion and engages with the base engagement portion.

The slider joint body of the present utility model includes: the base member in the slider structure of the present utility model described above; and the cover member of the slider structure of the present utility model engaged with the base member.

According to the slider structure of the present utility model, a slider connecting body that can exhibit the same operational effects as those of the present utility model described above can be formed.

Detailed Description

(Structure of this embodiment)

Hereinafter, embodiments of the present utility model will be described with reference to the drawings.

In fig. 1 to 4, a slider structure 1 according to the present embodiment includes: a 1 st slider 10 (slide fastener slider) and a 2 nd slider 20 (slide fastener slider) which are capable of sliding to engage with and disengage from each other element rows (fastener element rows) composed of helical fastener elements or the like provided along a pair of tapes (fastener tapes); and a slider connecting body 30 for connecting the 1 st slider 10 and the 2 nd slider 20 to each other in a facing manner.

In the following description, the X direction is defined as the sliding direction (longitudinal direction) of the slider structure 1, the Y direction orthogonal to the X direction is defined as the left-right direction (width direction) of the slider structure 1, and the Z direction orthogonal to the X, Y direction is defined as the up-down direction (thickness direction) of the slider structure.

In the present embodiment, the slider structure 1 is used as an adjustable slide fastener for adjusting the size of the abdomen, sleeve, or the like of the clothing as an article. The adjustable slide fastener includes a pair of tapes provided with the element rows described above and a slider structure 1. As a use example of the adjustable slide fastener, the tape is sewn to a garment, a base member 40 described later of the element row and slider structure 1 is disposed on the back side of the garment, and the 1 st slider 10 and the 2 nd slider 20 on the back side of the garment are slidably fitted to the element row. The pull tab 18 and the cover member 60, which will be described later, of the slider structure 1 are disposed on the front side of the garment, and the string-threading hole 411, which will be described later, is connected to a string-like body for adjusting the size of a specific portion such as the abdomen circumference or the sleeve circumference of the garment.

As shown in fig. 2, the 1 st slider 10 includes: a slider body 11 through which each element row is inserted from the rear opening 10B to the shoulder opening 10A; and a slider 18 for sliding movement of the slider body 11 along the pair of tapes in the X direction.

The slider body 11 is integrally formed of the same material from the upper plate portion 12, the lower plate portion 13, the column portion 14 connecting the upper plate portion 12 and the lower plate portion 13, and the connecting portion 15 connecting the tab 18, and a locking pin 16 as a locking member is attached to the connecting portion 15.

The lower plate portion 13 includes: a plate-shaped lower plate main body portion 131; and side plate portions 132 that stand upward from both side edges of the lower plate main body portion 131 in the Y direction, respectively.

The column portion 14 extends upward from a position of the shoulder rest 10A in the X direction of the lower plate main body portion 131 and a position substantially at the center in the Y direction.

The upper plate portion 12 includes: a plate-shaped upper plate body portion 121 formed on an upper portion of the column portion 14; and flange portions 122 extending inward in the Y direction from side plate portions 132 on both sides in the Y direction, respectively. In the present embodiment, the upper plate main body portion 121 and the flange portion 122 are formed in a manner separated from each other, with a belt passing therebetween.

The coupling portion 15 has a 1 st coupling convex portion 151 and a 2 nd coupling convex portion 152 formed so as to protrude upward from the upper plate body portion 121. The 1 st connecting convex portion 151 and the 2 nd connecting convex portion 152 are arranged at intervals in the X direction, the 1 st connecting convex portion 151 is arranged on the shoulder opening 10A side, and the 2 nd connecting convex portion 152 is arranged on the back opening 10B side. The 1 st coupling convex portion 151 has an upper surface 153 and a pair of left and right side surfaces 154 connected to the upper surface 153.

The lock pin 16 is disposed so as to extend across the 1 st coupling convex portion 151 and the 2 nd coupling convex portion 152, and has a hole (not shown) formed in the upper plate body 121 on the 2 nd coupling convex portion 152 side, and an engagement tip (not shown) capable of being inserted into and removed from the insertion path 17 through which the element row is inserted is disposed so as to face the hole. The engagement tip is engaged with the element row in a state protruding from the insertion path 17 (in a state of entering the hole), and is disengaged in a state of being submerged in the insertion path 17 of the upper plate body 121. In this engaged state, the slider structure 1 is in a state of being unable to slide along the pair of tapes, and in a state of being disengaged, is in a state of being able to slide.

The pull tab 18 includes a pull tab main body portion 181, and a pull tab shaft portion 183 formed at one end portion of the pull tab main body portion 181, and the pull tab shaft portion 183 is rotatably coupled to the coupling portion 15. The tab shaft portion 183 is disposed between the 1 st coupling convex portion 151 and the 2 nd coupling convex portion 152.

When a pulling force is applied to the tab main body portion 181 by the operation of the tab 18, the tab shaft portion 183 is elastically deformed by abutting against the lock pin 16, and the engagement tip of the lock pin 16 is immersed in the hole of the upper plate portion 12, and the engagement between the engagement tip and the element row is released. In the released state, the slider structure 1 is slidably movable along the pair of tapes, and the dimensions of the abdomen, sleeve, and the like of the garment can be adjusted by sliding the slider structure 1.

When the operation is completed and the pulling force is no longer applied to the tab main body portion 181, the lock pin 16, which elastically deforms the tab shaft portion 183, returns to its original shape, and the engagement tip of the lock pin 16 protrudes from the hole of the upper plate portion 12 to the insertion path 17 to be engaged with the fastener element row. In the engaged state, the slider structure 1 is in a state of being unable to slide along the pair of tapes, and the dimensions of the abdomen circumference, sleeve circumference, and the like of the garment are fixed.

As described above, in the present embodiment, the 1 st slider 10 is a so-called lock slider having a lock pin 16 to constitute a lock mechanism, but may be a normal slider having no lock pin 16 to constitute a lock mechanism.

The 2 nd slider 20 has a slider body 21 formed substantially in the same manner as the slider body 11 except for the coupling portion 15, and is different from the 1 st slider 10 in that it does not have a structure corresponding to the lock pin 16 and the tab 18. The same reference numerals are given to the slider body 21 as those of the slider body 11, as appropriate, and detailed description thereof will be omitted.

A coupling portion 25 as a protruding portion protruding upward is formed on the upper surface of the upper plate body portion 121 of the slider body 21. The coupling portion 25 includes a pair of coupling convex portions 251 spaced apart in the X direction. In the slider structure 1, the structure corresponding to the tab is not connected to the connecting portion 25, and if the structure corresponding to the tab 18 is connected to the connecting portion 25 and the 2 nd slider 20 is used as a slide fastener slider alone, the pair of connecting protrusions 251 are connected by caulking.

The shoulder openings 10A of the slider bodies 11, 21 are arranged so as to face each other in the X direction, and the rear openings 10B are arranged at positions farther from each other in the X direction than the shoulder openings 10A. Therefore, the element rows inserted into the insertion path 17 from one rear opening 10B of the slider bodies 11, 21 are separated laterally in the Y direction by the pillar portion 14, and the element rows fed out from the other rear opening 10B of the slider bodies 11, 21 are engaged with each other.

The slider joint body 30 includes: a base member 40 that holds the 1 st slider 10 and the 2 nd slider 20; and a cover member 60 that engages with the base member 40 and covers at least a part of the 1 st slider 10 and the 2 nd slider 20 from above.

In the present embodiment, the string-like body inserted through the string-insertion hole 411 is used to adjust the size of the clothing, such as around the abdomen or around the sleeve.

The base member 40 further includes: a 1 st reinforcing portion 49 that is disposed adjacent to the 1 st pressing portion 43 in a direction along the base bottom plate portion 41 (a direction along the in-plane direction of the X-direction and the Y-direction), and connects the base bottom plate portion 41 and the 1 st pressing portion 43; and a 2 nd reinforcing portion 48 which is disposed adjacent to the 2 nd pressing portion 44 in a direction along the base bottom plate portion 41, and connects the base bottom plate portion 41 and the 2 nd pressing portion 44. The 1 st reinforcing portion 49 and the 2 nd reinforcing portion 48 reinforce the 1 st pressing portion 43 and the 2 nd pressing portion 44.

The 1 st reinforcing portion 49 is disposed adjacent to the 1 st pressing portion 43 on one end side (the rope hole 411 side) of the base member 40 in the X direction. Since the 1 st reinforcing portion gradually increases in size in the X direction from above to below, the area connecting the 1 st reinforcing portion and the base bottom plate portion 41 also increases, and the 1 st pressing portion 43 is more firmly reinforced. The 1 st reinforcing portion 49 and the base bottom plate portion 41 form a portion having a substantially L-shaped cross section.

The 2 nd reinforcing portion 48 is disposed on the other end side of the base member 40 in the X direction, and is formed in an end plate shape. The 2 nd reinforcing portion 48 rising from the base bottom plate portion 41 is disposed between and connected to the left and right 2 nd pressing portions 44, thereby reinforcing the 2 nd reinforcing portion 48 more firmly. The 2 nd reinforcing portion 48 and the base bottom plate portion 41 form a portion having a substantially L-shaped cross section.

The portion of the base member 40 on the one end side in the X direction than the base engaging portion 51 is configured to hold the 1 st holding portion 45 of the 1 st slider 10. The portion of the base member 40 on the other end side in the X direction than the base engaging portion 51 is configured to hold the 2 nd holding portion 46 of the 2 nd slider 20. The 1 st holding portion 45 has a 1 st pressing portion 43, and the 2 nd holding portion 46 has a 2 nd pressing portion 44. The base engaging portion 51 is disposed between the 1 st holding portion 45 and the 2 nd holding portion 46.

In the 1 st holding portion 45, the lower plate main body portion 131 and the side plate portion 132 of the slider main body 11 are covered with the base bottom plate portion 41 and the pair of base side plate portions 42, and the pressing surface 431, which is the lower surface of the 1 st pressing portion 43, is abutted from above and presses a portion of the upper surface of the flange portion 122, which constitutes a part of the upper plate portion 12 of the slider main body 11, toward the rear opening 10B.

In the 2 nd holding portion 46, the lower plate main body portion 131 and the side plate portion 132 of the slider main body 21 are covered with the base bottom plate portion 41 and the pair of base side plate portions 42, and a pressing surface 441 as a lower surface of the 2 nd pressing portion 44 is brought into contact with and presses a portion of the upper surface of the flange portion 122, which constitutes a part of the upper plate portion 12 of the slider main body 21, toward the rear opening 10B from above.

As shown in fig. 4 to 7, the base engaging portion 51 includes: a pair of left and right engaging surfaces 52 formed on the distal end portion 451 of the engaging column 45A and on the 1 st holding portion 45 side; a pair of left and right guide surfaces 53 disposed above the pair of left and right engagement surfaces 52; and a pair of left and right auxiliary guide surfaces 54 connected to the pair of left and right guide surfaces 53 and disposed on the 2 nd holding portion 46 side with respect to the pair of left and right guide surfaces 53. The base engaging portion 51 further includes a restricting surface 55 for restricting movement of a pair of engaging claws 67, which will be described later, toward the 2 nd slider 20 in the X direction. The restricting surface 55 is formed by the surface on the 2 nd holding portion 46 side of the engaging column 45A, and is a surface along the Y direction and the Z direction. The restricting surface 55 is disposed on the 2 nd holding portion 46 side with respect to the engaging surface 52.

The pair of left and right engagement surfaces 52 are formed by surfaces along the X-direction and the Y-direction. The pair of left and right engaging surfaces 52 are disposed at the same position as or lower than the position of the pressing surfaces 431, 441 in the Z direction. Therefore, the engagement position where the cover member 60 engages with the engagement surface 52 is the same position as or a position below the position where the 1 st pressing portion 43 and the 2 nd pressing portion 44 press the upper plate portion 12 of each of the 1 st slider 10 and the 2 nd slider 20. The position in the Z direction of the engagement surface 52 (the engagement position described above) is located at the same position as or below at least the portion located on both sides in the Y direction with respect to the engagement surface 52 of the upper edge of the base side plate portion 42. In the present embodiment, the upper edge of the base side plate 42 is located along the X direction, and the engagement position is located at the same position as the upper edge in the Z direction.

The pair of right and left guide surfaces 53 are formed of inclined surfaces that gradually widen in the Y direction as they go downward from the top surface 452 of the engagement post 45A. The pair of left and right auxiliary guide surfaces 54 are disposed adjacent to the pair of left and right guide surfaces 53 on the 2 nd slider 20 side (the 2 nd holding portion 46 side), and are formed of inclined surfaces that gradually widen in the Y direction from the pair of left and right guide surfaces 53 toward the 2 nd slider 20 side. The pair of left and right auxiliary guide surfaces 54 are inclined obliquely upward from the 1 st slider 10 side (the 1 st holding portion 45 side) toward the 2 nd slider 20 side (the 2 nd holding portion 46 side).

The cover member 60 includes: a 1 st cover portion 61 that covers and presses at least a part of the upper surface 153 and a part of the pair of side surfaces 154 of the coupling portion 15 of the 1 st slider 10 from above; a 2 nd cover portion 62 that covers the coupling portion 25 that is at least a part of the 2 nd slider 20 from above; and a cover engaging portion 63 which is disposed between the 1 st cover portion 61 and the 2 nd cover portion 62 and engages with the base engaging portion 51.

The cover engaging portion 63 includes a pair of left and right engaging claws 67 extending downward from a pair of left and right side portions 66. As shown in fig. 4, in the engaging claw 67, a tip claw 671 located below extends inward in the Y axis direction, and an upper surface of the tip claw 671 becomes an engaging surface 672, and the engaging surface 672 engages with the engaging surface 52 of the base engaging portion 51 in the Z direction. The tip claw 671 is formed with a guided surface 673 inclined obliquely upward toward the Y-direction inner side, and since the guided surface 673 is inclined in this manner, the guided surface 673 can be smoothly guided by the guide surface 53 of the base engaging portion 51. Further, since the engagement claw 67 engages with the restricting surface 55 on the 2 nd slider 20 side in the X direction, the movement of the cover member 60 to the other end side in the X direction is restricted by the restricting surface 55. Further, the movement of the cover member 60 toward one end side in the X direction is restricted by the coupling portion 25 of the 2 nd slider 20.

The 1 st cover portion 61 includes an upper portion 65 and a pair of side portions 66 on the 1 st slider 10 side with respect to the engagement claws 67, and the 2 nd cover portion 62 includes an upper portion 65 and a pair of side portions 66 on the 2 nd slider 20 side with respect to the engagement claws 67. Accordingly, in the engaged state in which the cover engaging portion 63 is engaged with the base engaging portion 51, the upper portion 65 and the pair of side portions 66 constituting the 1 st cover portion 61 cover at least a part of the upper surface 153 and the pair of side surfaces 154 in the 1 st coupling convex portion 151 of the 1 st slider 10, and the upper portion 65 and the pair of side portions 66 constituting the 2 nd cover portion 62 cover the coupling portion 25 of the 2 nd slider 20, as shown in fig. 3, for example.

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

First, as shown in fig. 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, and the coupling portion 25 of the 2 nd slider 20 is covered with the 2 nd cover portion 62.

Then, the cover member 60 is further pushed downward, whereby the pair of left and right engaging claws 67 are guided by the pair of left and right guide surfaces 53 of the base engaging portion 51 and pushed outward in the Y direction. At this time, even if the engaging claw 67 engages with the pair of left and right auxiliary guide surfaces 54, the engaging claw 67 is guided to the guide surface 53 side by the auxiliary guide surfaces 54.

Then, by pushing the cover member 60 further downward, the pair of left and right engaging claws 67 passes over the pair of left and right guide surfaces 53, and the engaging surface 672 of the tip claw portion 671 is disposed below the engaging surface 52 of the base engaging portion 51, whereby the engaging claw 67 is restored to the original state, and the engaging surface 672 is engaged with the engaging surface 52 in the Z direction.

At this time, as described above, the engagement position of the cover engagement portion 63 with the base engagement portion 51 is the same position as or a position lower than the pressing position in the Z direction at which the 1 st pressing portion 43 and the 2 nd pressing portion 44 press the 1 st slider 10 and the 2 nd slider 20. Therefore, the slider structure 1 can be configured such that the foreign matter is less likely to be caught by the cover engaging portion 63 than in the case where the engaging position is located at the upper position of the pressing position, for example, as described above, and the possibility that the cover member 60 is separated from the base member 40 due to the foreign matter being caught can be reduced.

In a state where the cover member 60 is engaged with the base member 40, the 1 st cover portion 61 covers and presses the upper surface 153 and a part of the pair of side surfaces 154 of the 1 st coupling convex portion 151 of the 1 st slider 10. Therefore, even if an external force is applied to the coupling portion 15 of the 1 st slider 10 by twisting the tab 18, the cover member 60 presses not only a portion of the upper surface 153 of the coupling portion 15 but also a portion of the pair of side surfaces 154, so that the 1 st slider 10 and the cover member 60 can be prevented from rocking with respect to each other, and the possibility that the cover member 60 is deviated from the predetermined position with respect to the 1 st slider 10 can be reduced.

(modification)

In the above embodiment, the position where the cover engaging portion 63 engages with the base engaging portion 51 is arranged at the same position as or at a position lower than the pressing position in the Z direction where the 1 st pressing portion 43 and the 2 nd pressing portion 44 press the 1 st slider 10 and the 2 nd slider 20 on the upper plate portion 12, but may be located at a position higher than the pressing position when the cover member 60 is configured to be less likely to be detached from the base member 40 due to the engagement of a foreign matter or the like. In addition, the engagement position may be disposed at the same position as or lower than the position of the upper surface of the upper plate portion 12 of the 1 st slider 10 or the 2 nd slider 20 in the Z direction, and in this case, it is possible to make it more difficult for foreign matter or the like to be engaged with the engagement portion, and it is possible to make it more difficult for the engagement of the cover engagement portion 63 with the base engagement portion 51 to be disengaged.

In the above embodiment, the position of the engagement surface 52 in the Z direction (the above engagement position) is disposed at the same position as or lower than the upper edge of the base side plate portion 42, but may be disposed at a position higher than the upper edge of the base side plate portion 42 when the cover member 60 is configured to be less likely to be detached from the base member 40 due to the engagement of a foreign matter or the like, as in the above.

In the above embodiment, the base engaging portion 51 includes the pair of guide surfaces 53 that gradually widen in the Y direction as going downward, and the pair of auxiliary guide surfaces 54 that gradually widen in the Y direction as going toward the 2 nd slider 20 side, and the engagement with the cover engaging portion 63 can be performed more smoothly, but the base engaging portion 51 may not be provided with the pair of guide surfaces 53 or the pair of auxiliary guide surfaces 54, as long as the structure can be engaged with the cover engaging portion 63, and therefore the structure of the pair of guide surfaces 53 or the pair of auxiliary guide surfaces 54 may be omitted. In the case where the pair of guide surfaces 53 and the like are omitted, the structure of the guided surface 673 of the engagement claw 67 may be maintained, or may be omitted.

In the above embodiment, the coupling portion 25 is formed in the 2 nd slider, but this structure may be omitted.

In the above embodiment, the cover member 60 is configured to press at least a part of the upper surface 153 and a part of the pair of side surfaces 154 in the coupling portion 15 of the 1 st slider 10, thereby reducing the possibility that the cover member 60 will deviate from a predetermined position with respect to the 1 st slider 10 when the tab 18 is twisted, for example. However, in the case where the main purpose is to reduce the detachment of the cover member 60 from the base member 40 due to the engagement of foreign matter or the like, the cover engaging portion 63 and the base engaging portion 51 may be disposed at the same position or at a position lower than the pressing position in the Z direction of the upper plate portion 12 of the 1 st slider 10 and the 2 nd slider 20 by the 1 st pressing portion 43 and the 2 nd pressing portion 44, and the cover member 60 may not press the upper surface 153 or the side surface 154 of the coupling portion 15 of the 1 st slider 10.
