Further, it is said that the entire upper portion of the slider main body protrudes toward the upper side with respect to the pair of chain cloths of the slider to occupy a considerable ratio, and therefore, it is one of the important elements for forming the appearance of the zipper. However, in Patent Document 1, the specific value indicating how much the upper portion of the slider body protrudes upward from the pair of chain fabrics is of course not disclosed as a standard for estimating a specific numerical value. Further, in the slider disclosed in Patent Document 1, as described above, the upper surface of the slider main body is formed to be higher than the upper surface of the arm to the upper surface of the arm, and therefore, a thicker impression is produced.

The present invention has been made in consideration of the above-described actual circumstances, and an object thereof is to provide a slider which minimizes the amount of protrusion of the upper portion of the slider body from the upper side of the pair of chain fabrics, and a slide fastener using the same.

The sliding member of the zipper of the present invention comprises: a slider body that moves forward and backward with respect to a pair of chain gear rows, the pair of chain gear rows extending along the front and rear sides of the pair of chain cloths on the right and left opposite sides The lower portion of the edge portion is fixed; a pair of support shafts project laterally from left and right sides of the upper portion of the slider body located above the pair of chain fabrics; and a pull tab that supports the pair of support shafts. Further, the slider main body is previously provided with a sprocket passage through which a pair of fastener elements are passed, and a chain having a front end as a pair of introduction ports and a rear end as one engagement opening. The tooth passages are provided with a pair of chain cloths passing through the pair of chain cloths in communication with the element tooth passages on the left and right side surfaces thereof.

Further, the first aspect of the slider of the present invention is such that the diameter of the fulcrum <the maximum thickness dimension of the upper and lower directions of the upper portion of the slider main body is <2.5 mm.

Further, the upper portion of the slider main body is formed to have the thickest portion in the front-rear direction regardless of whether or not the upper surface thereof is a horizontal surface, regardless of whether the thickness of the left and right end portions in the vertical direction is the largest. However, in order to reduce the amount by which the upper portion of the slider main body protrudes upward from the pair of chain fabrics, it is desirable to set it as follows.

That is, the second aspect of the slider of the present invention includes not only the first aspect but also the slider The upper surface of the main body has a rising inclined surface that is inclined upward from the front end toward the intermediate portion in the front-rear direction, and the thickness of the upper and lower end portions is formed to be the thickest in the intermediate portion in the front-rear direction. Further, the pair of support shafts project laterally from the left and right end portions of the upper portion of the slider main body and the intermediate portion in the front-rear direction.

Further, regardless of the relationship between the slider main body of the slider and the up-and-down direction of the tab, it is preferable to reduce the amount of the upper portion of the slider main body to the upper side of the pair of chain fabrics.

That is, the third aspect of the slider of the present invention includes not only the first aspect or the second aspect, but also the pull tab includes a pull tab body grasped by a finger, and a pair of arms extending from the left and right sides of the pull tab body And a pair of arms having a ring through which the support shaft passes are formed at the front end portions thereof. Moreover, the upper surface of the slider body is formed to be lower than the upper surface of the ring of the arm.

Moreover, the fourth aspect of the slider of the present invention includes, regardless of whether or not the first aspect is included, the pull tab includes a pull tab body grasped by a finger, and a pair of arms extending from the left and right sides of the pull tab body and A pair of arms having a ring through which the fulcrum passes are formed at the front end. Moreover, the upper surface of the slider body is formed to be lower than the upper surface of the ring of the arm.

Moreover, the slider main body has a shape regardless of the plan view. Moreover, since the force when the pull piece is moved is directly transmitted from the support shaft to the intermediate portion in the front and rear directions of the upper portion of the slider body, the strength of the upper portion of the slider body is improved when the size of the middle portion of the middle portion is shortened as much as possible. Not easy to break. On the other hand, the dimension in the left-right direction of the intermediate portion of the slider main body in the front-rear direction has the minimum size required for the pair of fastener elements to pass.

Further, in the case of a zipper including two sliders, it is desirable to reduce the amount of protrusion of the pair of chain fabrics on the upper portion of the slider main body and to increase the water repellency when the two sliders collide.

That is, the zipper of the present invention includes two sliders and is disposed in a state in which the front ends of the two sliders are opposed to each other, and in the case of each of the slider bodies, the left and right sides of the upper portion are self-contained The way in which the middle portion in the front-rear direction faces the front side and gradually faces the middle portion in the left-right direction It is formed, and its upper front side is formed in a straight line parallel to the left-right direction.

When the sliding member of the present invention conforms to the diameter of the fulcrum <the maximum thickness dimension of the upper and lower directions of the upper portion of the slider main body <2.5 mm, the protruding length which protrudes upward from the pair of chain fabrics and the amount of protrusion can be sufficiently reduced.

Further, in the slider, the upper surface of the slider body is a rising inclined surface that is inclined upward from the front end toward the intermediate portion in the front-rear direction, and the thickness of the left and right end portions in the upper and lower directions is in the middle portion in the front-rear direction. When it is formed to be the thickest, the strength of the fulcrum (sufficient thickness) can be ensured by making the fulcrum project laterally from the portion where the fulcrum is formed to the thickest portion, and the pair of chain cloths can be further protruded upward. The amount of protrusion.

Further, in the slider, the pull tab is formed as a pull tab body that is gripped by a finger, and one of the pair of arms is extended from the left and right sides of the pull tab body, and a loop for the support shaft is formed at the front end portion thereof. The pair of arms, and the upper surface of the slider body is formed to be lower than the upper surface of the arm ring, thereby reducing the amount of protrusion of the pair of chain cloths to the upper side.

In the zipper of the present invention in which the two sliders are disposed opposite to each other, the left and right sides of the upper portion of the slider body are gradually oriented toward the front side with respect to the front side from the front-rear direction. The direction of the middle portion is formed. Therefore, the width of the left and right widths of the middle portion of the slider body in the front and rear directions can be used to the minimum necessary size for the passage of a pair of chain rows, and the upper portion of the slider body can be reduced. A pair of chain cloths protrudes upward from the side. Further, when the front side of the upper portion of the slider main body of the two sliders is formed in a straight line parallel to the left-right direction, the water stoppage at the time of collision of the two sliders can be improved.

In the following description, the front side refers to the upper side in FIG. 3, the rear side refers to the lower side in FIG. 3, and the upper side refers to the front side with respect to the paper surface of FIG. 3, and the lower side refers to the front side. The paper surface of 3 is the inside. The right side refers to the right side in FIG. 3, and the left side refers to the left side in FIG.

A pair of zipper chain belts 2, 2 are provided with: a pair of chain cloths 21, 21 which are extended forward and backward and Arranged in parallel on the left and right; a pair of sprocket rows 22, 22 fixed along the lower surface of the left and right side edges of the pair of chain fabrics 21, 21; two front stops 23, one at The front side of the element rows 22, 22 are respectively fixed with respect to the respective chain cloths 21; and one rear stop 24 is fixed to the rear side of the pair of element rows 22, 22 with respect to the pair of chain pieces 21, 21. .

Each of the element rows 22 is formed by a plurality of fastener elements 22a arranged along the lower surface of the opposite side edges of the chain cloth 21 at intervals in the front and rear. In the present embodiment, a plurality of fastener elements are used. 22a is formed by spiral continuous spiral teeth. If the slider 3 is moved forward in order to close the pair of fastener tapes 2, 2, the pair of fastener elements 22, 22 are engaged with each other by the slider 3 and the front stopper 23, The slider 3 can be prevented from moving further forward. Further, when the sliders 3 are moved rearward in order to open the pair of fastener tapes 2, 2, the pair of fastener elements 22 and 22 are separated from each other to the left and right by the slider 3 and the rear stopper. The collision of 24 prevents the slider 3 from moving further rearward.

Further, each of the chain fabrics 21 is preferably a thin, elongated and rectangular shape in plan view, and is, for example, a multilayer structure or a resin-made chain body obtained by covering the upper surface of the fabric body of the fabric with a waterproof film made of resin. The single layer structure is water resistant.

The slider 3 of the first embodiment of the present invention, as shown in FIGS. 1 to 9, includes a slider body 4 that is engaged with a pair of chain rows 22, 22 and movable forward and backward; a pair of spindles 5, 5, which protrudes laterally from the left and right sides of the slider body 4; and a pull tab 6, which is supported by a pair of support shafts 5, 5.

The pair of support shafts 5 and 5 protrude laterally from the left and right side faces of the upper blade 41 in the rear direction and are arranged in a straight line in the left-right direction. Each of the fulcrums 5 is a circular rod and has a diameter 5d greater than, for example, 0.9 mm.

The slider body 4 includes an upper blade 41 and a lower blade 42 which are disposed to face each other at an upper and lower intervals, and a connecting post 43 which is bridged between the upper blade 41 and the lower blade 42. The middle portion in the left-right direction and the four flanges 44, 44, ... protrude from the right and left end portions of both the upper blade 41 and the lower blade 42 toward the upper and lower sides. Again, slippery Inside the main body 4, a sprocket path 45 through which the pair of sprocket rows 22, 22 pass, and a pair of chain slats 21, 21 pass through the pair of chain grooves 46, 46 are formed. Incidentally, the slider body 4 may be made of metal or resin. However, in order to reduce the thickness of the upper blade 41 and the like, it is preferably made of metal (for example, an alloy of copper and zinc), for example, die-casting can be used. Formed by law.

The upper blade 41 has a flat surface on the upper surface and the lower surface. The plane here includes not only the horizontal plane but also the curved surface which is arc-shaped in side view or the combination of the curved surface and the horizontal plane. In the present embodiment, the front surface of the upper surface of the upper blade 41 is a rising inclined surface 41s which is inclined upward from the front end toward the intermediate portion in the front-rear direction as shown in FIG. 4 or FIG. 9 (more specifically, a curved surface that is convex in an arc shape). Further, the upper surface of the upper blade 41 has a horizontal surface extending in the tangential direction of the curved surface of the front portion in the front-rear direction intermediate portion and the rear portion.

On the other hand, the lower surface of the upper blade 41 is as shown in Fig. 2, Fig. 4 or Fig. 9, and the edge portion of the front portion is a descending inclined surface which gradually descends from the outer peripheral edge toward the central portion of the lower surface ( If it is explained in more detail, it is an inclined surface with a certain angle). The descending inclined surface is formed by two descending inclined faces 41u and 41u formed at the front end portion in the front portion of the lower surface of the upper blade 41, and two descending portions formed on the left and right side portions in the front portion of the lower surface of the upper blade 41. The inclined surfaces 41v and 41v are configured. The two descending inclined surfaces 41u and 41u of the front end portion are inclined surfaces that gradually descend from the front end toward the rear, and are formed to be separated left and right by the connecting post 43 formed at the intermediate portion in the left-right direction of the lower surface of the upper blade 41. Further, one of the left and right side portions of the descending inclined surfaces 41v and 41v is a slope that gradually descends from the left end and the right end toward the intermediate portion in the left-right direction. Further, on the lower surface of the upper blade 41, four descending inclined faces 41u, 41u, 41v, and 41v, that is, portions other than the edge portion of the front portion are set as a horizontal plane.

Further, in plan view, the shape of the upper blade 41 is a bilaterally symmetrical shape as shown in FIG. 3, and the front side 41a and the rear side 41b are linearly parallel to the left-right direction, and the entire length of the front side 41a is formed later than the rear side 41b. The total length is short. Incidentally, the front end surface of the upper blade 41 including the front side 41a is a vertical plane parallel to the vertical direction. Also, the left and right sides of the upper wing 41 The width dimension is formed such that the intermediate portion in the front-rear direction (corresponding to the portion of the protruding portions of the pair of support shafts 5, 5) is formed wider than the entire length of the front side 41a and the rear side 41b. Further, the front portions of the left and right side edges 41c and 41d of the upper blade 41 are formed so as to gradually face the intermediate portion in the left-right direction as the width is widen from the front to the rear, and the left and right sides 41c of the upper blade 41 are formed. The 41d rear portion is also formed so as to gradually move toward the middle portion in the left-right direction as the intermediate portion in the front-rear direction from the widest width toward the rear.

As shown in FIGS. 1 and 2, the lower blade 42 has a bilaterally symmetrical shape in plan view. However, the shapes of the front and rear portions of the lower blade 42 and the upper blade 41 are different from each other. As will be described in more detail, the front portion of the lower blade 42 is formed in a shape that is convex in an arc shape toward the intermediate portion in the left-right direction. In the rear portion of the lower blade 42 , the rear side has a linear shape parallel to the left-right direction, and the left and right side edges are formed in an arc shape gradually toward the rear in the left-right direction as the intermediate portion in the front-rear direction faces rearward. The shape of the depression.

Further, the lower blade 42 also has a flat surface on the upper surface and the lower surface. As shown in FIG. 1 or FIG. 4, the edge portion of the upper surface of the lower blade 42 is a rising inclined surface 42u and 42u which gradually rise toward the central portion of the upper surface (if it is described in more detail, it is a belt Angled surface with a certain angle). Incidentally, the rising inclined surface is formed by the two rising inclined surfaces 42u and 42u, and is formed to be separated left and right by the connecting post 43 formed at the intermediate portion in the left-right direction of the lower surface of the lower blade 42. However, since the front portion of the lower blade 42 has a shape of an arc-shaped projection, it is sufficient to specify the position of the rising inclined surface of the lower blade 42 by the description of the edge of the front portion of the upper surface of the lower blade 42. . Therefore, in order to specify the position at which the rising inclined surface of the lower blade 42 is formed, it is not necessary to specify the "front front end portion and the front left and right side portions" of the lower inclined surface of the upper blade 41 as detailed. The designation of the front, rear, and left and right directions of the front. Further, the upper surface of the lower blade 42 is a horizontal plane other than the edge portion of the front inclined portion, and the lower surface of the lower blade 42 is also a horizontal surface.

The upper and lower dimensions of the respective flanges 44 projecting from the upper side of the upper wing 41 toward the lower side are shorter than the upper and lower sides of the flanges 44 which protrude upward from the lower side of the lower wing 42. Moreover, the left side The flanges 44, 44 cover the left and right sides of the pair of element rows 22, 22, and the upper two flanges 44, 44 are located above the pair of links 21, 21. Moreover, in the illustrated example, the lower surface of the upper two flanges 44, 44 is a horizontal plane. If it is described in more detail, most of the parts (ie, the portion other than the rear end portion) are set to a horizontal plane. The rear end portion is formed into a shape obtained by chamfering so as to be convex upward in the arc shape above the horizontal surface. Similarly, the upper surfaces of the two lower flanges 44 and 44 on the lower side are also horizontal surfaces. If more detailed, the majority (ie, the portions other than the front end portion and the rear end portion) are set as a horizontal plane. The front end portion and the rear end portion are formed to have a shape obtained by chamfering in a circular arc shape on a lower side than the horizontal surface, and the radius of the arc of the front end portion is smaller than the radius of the arc of the rear end portion .

The upper portion of the slider body 4 is constituted by the two flanges 44, 44 on the upper side and the upper blade 41 as described above. That is, the upper portion of the slider body 4 does not include the connecting post 43. Further, as shown in Fig. 6, the upper portion of the slider body 4 has a maximum thickness dimension t in the vertical direction as the diameter 5d (e.g., 0.9 mm) of the support shaft 5 < t < 2.5 mm. It is preferably set to t < 2.3 mm. Incidentally, in the present embodiment, with respect to the upper surface of the upper blade 41, the intermediate portion and the rear portion in the front-rear direction are horizontal planes and are the highest positions, and the lower surfaces of the upper two flanges 44, 44 are at the same level. And become the lowest position. Therefore, in the present embodiment, the middle portion to the rear portion of the right and left end portions of the slider main body 4 have portions having the maximum thickness dimension t in the vertical direction. Therefore, the maximum thickness dimension t in the up-and-down direction refers to the dimension in the up-and-down direction between the upper surface of the upper blade 41 and the lower surface of the pair of upper flanges 44, 44 on the upper side.

As shown in FIGS. 7 and 8, the element-toothed passages 45 are vertically separated from the outside by the upper and lower blades 41 and 42, and are separated from the outside by the four flanges 44, 44, . Space and space that runs through in the front and rear direction. Further, the rear portion of the element tooth passage 45 is linearly extended, and the rear end of the element tooth passage 45 serves as a meshing port 45b through which the element rows 22 and 22 pass. On the other hand, the front portion of the sprocket passage 45 is branched into two sides in the front direction by the connecting post 43, and the front end of the sprocket passage 45 becomes one of the separated states, and the pair of sprocket rows 22, 22 pass through the pair of inlets. 45a, 45a. That is, the element tooth passage 45 becomes a Y word as a whole. shape. When the pair of zipper tapes 2, 2 are opened, that is, when the slider 3 is moved rearward, one of the meshing states is paired with the sprocket rows 22, 22 and one of the pair of upper slats 21, 21 The self-engaging port 45b is introduced into the sprocket passage 45. Then, the pair of element rows 22 and 22 are separated to the left and right by the connecting post 43, and one of the separated states is discharged to the element rows 22 and 22 together with the pair of chain members 21 and 21 from the introduction port 45a. On the other hand, when the pair of fastener tapes 2, 2 are closed, that is, when the slider 3 is moved forward, one of the separated states is the pair of the fastener elements 22, 22 and the pair of chain fabrics 21, 21. The introduction port 45a is introduced into the element path 45 together. Then, on the rear side of the connecting post 43, a pair of element rows 22, 22 are engaged, and one of the meshing states is discharged to the element rows 22, 22 from the engaging port 45b.

Each of the chain grooves 46 is formed in a space between the upper and lower flanges 44, 44. The left and right chain grooves 46 and 46 communicate with the left and right of the element path 45. Further, since the protruding length of the upper flange 44 protruding downward is shorter than the protruding length of the lower flange 44, the respective chain grooves 46 are formed to be in a state of being connected to the upper side of the sprocket passage 45.

The pull tab 6 includes a pull tab body 61 that is gripped by a finger, and a pair of arms 62, 62 extending from the left and right sides of the pull tab body 61. Each arm 62 has a rod shape, and a ring 62a through which the support shaft 5 passes is formed at the front end portion thereof. Further, the hole formed on the inner peripheral side of the ring 62a penetrates in the left-right direction and has a circular shape, and the radius of the hole is formed to be slightly larger than the radius of the support shaft 5 as shown in FIG. Further, the outer circumference of the ring 62a is also circular, and more specifically, since the arm 62 has a shape elongated in a rod shape, it has a C-shape. The radius of the outer circumference of the ring 62a is set to be the same as the distance from the center of the support shaft 5 to the lower end of the lower end of the flange 44 of the upper side. In view of the relationship between the size of the hole forming the ring 62a and the radius of the outer circumference as described above, the lowermost end of the outer circumference of the ring 62a attached to the support shaft 5 is substantially the same as the lower end of the upper flange 44. On the other hand, the uppermost end of the outer circumference of the ring 62a is as shown in Fig. 5, and the upper surface of the slider main body 4, that is, the upper surface of the upper wing 41, is maintained in a state where the left and right arms 62, 62 are horizontal. The predetermined size 62t is projected to the upper side. Therefore, the upper surface of the slider main body 4 is formed lower than the upper surface of the ring 62a of the left and right arms 62, 62. Furthermore, the handle body 61 has a frame shape.

In the slider 3 according to the first embodiment of the present invention, the maximum thickness dimension t in the upper and lower directions of the upper portion of the slider main body 4 is set to the diameter 5d (for example, 0.9 mm) of the support shaft 5 < t < 2.5 mm, and therefore, The protruding length of the pair of chain fabrics 21, 21 protruding more upward is sufficiently reduced, thereby reducing the amount of protrusion.

Further, in the slider 3, the thickness of the upper and lower ends of the slider main body 4 is formed to be the thickest in the upper-rear direction in the front-rear direction, and the support shaft 5 is formed to the thickest portion from the uppermost portion thereof. The square is protruded, whereby the strength (thickness) as the support shaft 5 can be ensured. Further, in the slider 3, the upper surface of the slider main body 4 is a rising inclined surface 41s which is inclined upward from the front end toward the intermediate portion in the front-rear direction, and the lower end front end portion is also set as the descending inclined surface. 41u, therefore, the amount of protrusion that protrudes upward from the pair of chain fabrics 21, 21 can be sufficiently reduced.

Further, the slider 3 is formed such that the upper surface of the slider main body 4 is formed to be lower than the upper surface of the ring 62a of the arms 62, 62, so that the pair of chain fabrics 21, 21 can be more protruded upward. The amount of protrusion.

Further, the slider main body 4 is formed such that the upper and lower sides 41c and 41d of the upper portion are gradually formed toward the intermediate portion in the left-right direction as the intermediate portion from the front-rear direction toward the front side 41a. Therefore, the slider body 4 can be oriented in the front-rear direction. The width dimension of the left and right sides of the intermediate portion is the minimum necessary size for the passage of the pair of chain rows 22, 22, and the amount of protrusion of the upper portion of the slider body 4 to the upper side of the pair of chain fabrics 21, 21 can be reduced. .

As such, the slider 3 of the first embodiment can reduce the amount of protrusion that protrudes upward from the pair of chain fabrics 21, 21, and therefore, can leave an overall thin impression.

The slide fastener 1 of the second embodiment of the present invention to which the slider 3 of the first embodiment of the present invention is applied is attached to a pair of the front ends of the two sliders 3 and 3 as shown in FIG. Zipper chain straps 2, 2. A gap 2a is formed between the pair of fastener tapes 2, 2 (between the pair of fastener rows 22 and 22 as described in more detail) between the front and rear of the two sliders 3, 3.

When the two sliders 3, 3 are gradually approached, the gap 2a is narrowed. Then, if 2 sliders When the collision occurs in 3 and 3, the gap 2a disappears. As shown in Fig. 11, the front end of the slider 3 is in contact with each other, and the water stopping property in the state in which the pair of fastener tapes 2 and 2 are closed is improved. Further, since the front side 41a of the upper wing 41 of each of the sliders 3 and 3 has a linear shape parallel to the left-right direction, and the front end surface including the front side 41a is a vertical plane parallel to the vertical direction, it is easy to maintain the front end surface of the slider 3. The state of collision with each other.

Incidentally, when the two sliders 3 and 3 are brought close to each other, as shown in FIG. 10, the pair of chain fabrics 21 and 21 are located at the left and right portions of the two sliders 3 and 3 (hereinafter referred to as " The portion near the slider" is deformed in an arc shape so as to protrude outward. This deformation is apparent when the two sliders 3, 3 collide as shown in FIG. Further, since the user usually pulls the slider 6 upward and the slider 3 is moved, the vicinity of the sliders of the pair of chain fabrics 21 and 21 has a shape slightly raised upward. Further, since the zipper 1 fixes the side opposite to the opposite side edge portions of the pair of chain fabrics 21 and 21 to an object such as clothes, the vicinity of the slider is further upward in the pair of chain fabrics 21 and 21. The shape of the uplift. The shape of the ridge is allowed to be one of the ideal shapes of the two sliders 3, 3. It is assumed that the two sliders 3 and 3 cannot maintain the collision state from the respective sliders 3, and the two sliders 3 and 3 cannot be separated from each other, and the water is prevented from being secured. However, since the left and right side edges 41c and 41d of the upper portion of the slider 3 are formed so as to gradually face the intermediate portion in the left-right direction toward the front side 41a from the front-rear direction, for example, the left and right sides of the pair of sliders 3, for example. When 41c and 41d are linearly parallel to the front-rear direction, the vicinity of the slider in the pair of chain fabrics 21 and 21 is allowed to bulge upward. Further, in each of the sliders 3, since the edge portions of the front portions of the lower surface of the upper blade 41 are the descending inclined faces 41u, 41u, 41v, and 41v, for example, the lower surface of the upper blade 41 is set only for example. In the case of the slider of the horizontal plane, the vicinity of the slider in the pair of chain fabrics 21, 21 is allowed to protrude upward.

The first modification of the slider 3 according to the first embodiment of the present invention is as shown in Figs. 12 and 13, and the first embodiment is attached to the upper surface of the upper blade 41 with the decorative sheet 7 attached thereto. The shape of the slider 3 is different.

The sheet 7 is formed by printing characters, figures, symbols, and the like with a desired color on the upper surface.

The present invention is not limited to the above-described embodiments, and can be appropriately modified without departing from the spirit and scope of the invention. For example, in the slider 3 of the present embodiment, the maximum thickness t of the upper portion of the upper portion of the slider main body 4 is t < 2.5 mm, but the present invention is not limited thereto, and may be set to t ≧ 2.5 mm. In this case, the upper surface of the slider body 4 is formed to be lower than the upper surface of the pair of rings 62a, 62a of the arms 62, 62.

Further, the front side 41a of the slider 3 of the present embodiment has a linear shape parallel to the left-right direction. However, the present invention is not limited thereto, and may have other shapes such as a shape of an arc-shaped projection.

Further, in the left and right end portions of the slider main body 4 of the present embodiment, the flange 44 is provided on both the upper portion and the lower portion. However, the flange 44 is not limited thereto, and the flange may be provided only at the left and right end portions of the lower portion of the slider main body 4. 44, and no flange 44 is provided at the left and right ends of the upper portion of the slider body 4.

Further, in the slider 3 of the present embodiment, the shapes of the upper and lower blades 41 and 42 are different, but the shape of the upper and lower blades 41 and 42 may be the same.
