Description

本考案は、社員証、ＩＤカード等を保持するネックストラップにおけるストラップ（平紐）の端を保持するための平紐保持装置に関する。 The present invention relates to a flat cord holding device for holding an end of a strap (flat cord) in a neck strap for holding an employee ID card, an ID card and the like.

平紐（ストラップ）は、いわゆるネックストラップとして社員証、ＩＤカード等の保持に使用され、また、ハンドストラップとして携帯電話、カメラ等に使用される。ネックストラップおよびハンドストラップは、一般に、平紐の両端が何らかの連結具に取り付けられて、全体としてループ状に形成されている。
従来、平紐の端の連結具への取り付け（保持）は、連結具の内面から平紐の表面両側に向けてそれぞれ突出する突起により平紐の端部を挟むことにより行われることが多い（特許文献１）。 The flat string (strap) is used as a so-called neck strap for holding an employee ID card, an ID card, and the like, and is used as a hand strap for a mobile phone, a camera, or the like. The neck strap and the hand strap are generally formed in a loop shape as a whole by attaching both ends of a flat cord to some kind of connecting device.
Conventionally, attachment (holding) of the end of the flat cord to the coupling tool is often performed by sandwiching the end portion of the flat cord by protrusions protruding from the inner surface of the coupling tool toward both sides of the flat cord surface (Patent Document 1). ).

平紐の端部の表面両側を突起により挟む保持方法では、強固に平紐と連結具を一体化するためには、突起の数を多くする必要がある。しかし、連結具に挟まれる平紐の面積は大きくなく、設けることができる突起の数には制限があって、この要求の実現は容易ではない。そこで、強固に平紐と連結具とを一体化する意図で、連結具に「折り返しバー」を設けて平紐の端部を折り返しバーにより折り重ね、重ねた部分を連結具内面に対向して突出する突出片で挟む技術が提案されている（特許文献２）。 In the holding method in which both sides of the surface of the end portion of the flat cord are sandwiched by the projections, it is necessary to increase the number of projections in order to firmly integrate the flat cord and the connecting tool. However, the area of the flat cords sandwiched between the couplers is not large, and the number of protrusions that can be provided is limited, and this requirement is not easily realized. Therefore, for the purpose of firmly integrating the flat string and the connecting tool, a “folding bar” is provided on the connecting tool, the end of the flat string is folded by the folding bar, and the overlapped portion protrudes opposite the inner surface of the connecting tool. A technique for sandwiching between protruding pieces has been proposed (Patent Document 2).

特許文献２に提案された技術は、折り返しバーを設けたことにより、少ない突出片の数で平紐と連結具との強固な連結を期待することができる。
しかし、特許文献２に提案された技術は、平紐を折り返しバーで折り返し、平紐の端部を二重にした後に二重部分を連結具で挟むので、その保持手順が煩雑であって作業性に問題を有する。 The technique proposed in Patent Document 2 can be expected to provide a strong connection between the flat string and the connector with a small number of protruding pieces by providing the folding bar.
However, the technique proposed in Patent Document 2 is that the flat string is folded back with a folding bar, the end of the flat string is doubled, and then the double part is sandwiched between the connecting tools. Have a problem.

爪収容部４５における幅方向両側の端面に設けられた矩形の「切り欠き」には、係合部４９が備えられる。係合部４９は、図４を参照して、切り欠きの奥（平面視矩形における深部の辺）から幅方向外方に突出する。幅方向外方に突出する係合部４９は、厚さ方向において爪収容部４５の開口側に偏っている（図４では、厚さ方向について上側に偏る位置である）。幅方向に突出する係合部４９は、爪収容部４５の開口とは反対側を向く係合面５２を有する。ここで「厚さ方向」とは、爪形成部１３、折り曲げ部１４および押圧部１５の並び方向、ならびに幅方向のいずれにも直交する方向（図４における上下方向）をいう。「爪形成部１３、折り曲げ部１４および押圧部１５の並び方向」を「長手方向」といことがある。 Engaging portions 49 are provided in rectangular “notches” provided on the end surfaces on both sides in the width direction of the claw accommodating portion 45. Referring to FIG. 4, the engaging portion 49 protrudes outward in the width direction from the back of the notch (the side of the deep portion in the plan view rectangle). The engaging portion 49 protruding outward in the width direction is biased toward the opening side of the claw accommodating portion 45 in the thickness direction (in FIG. 4, the position is biased upward in the thickness direction). The engaging portion 49 protruding in the width direction has an engaging surface 52 facing the side opposite to the opening of the claw accommodating portion 45. Here, the “thickness direction” refers to a direction (vertical direction in FIG. 4) orthogonal to any of the direction in which the nail forming portion 13, the bent portion 14 and the pressing portion 15 are arranged and the width direction. The “alignment direction of the nail forming portion 13, the bent portion 14, and the pressing portion 15” may be referred to as a “longitudinal direction”.

係合部４９は、長手方向に長く、その長さは、同方向における（鍵部１９の）係止部３２の長さよりも長い。
雄部材１は、ポリカーボネート樹脂により製造される。雄部材１は、適度な弾性を有する他の材料で形成することができる。
平紐保持装置３による平紐４の保持は、以下のように行われる。 The engaging portion 49 is long in the longitudinal direction, and the length thereof is longer than the length of the locking portion 32 (of the key portion 19) in the same direction.
The male member 1 is manufactured from a polycarbonate resin. The male member 1 can be formed of other materials having appropriate elasticity.
The flat string 4 is held by the flat string holding device 3 as follows.

図５は平紐４が固定された平紐保持装置３の図１におけるＡ−Ａ矢視に相当する断面図、図６は同状態の図１におけるＢ−Ｂ矢視に相当する断面図である。
初めに、平紐４の端が、肉抜き孔４１を通過させ、爪形成部１３における位置決め孔３６，３６近くに置かれる。平紐４は、爪部１８に向けて押しつけられる。この押しつけ作業は省略してもよい。平紐保持装置３（雄部材１）は、爪２２を内側にして折り曲げ部１４から二つ折りされる。二つ折りは、２つの位置決め突起４４，４４が２つの位置決め孔３６，３６のそれぞれ異なる一方に嵌り込むようになされる。 5 is a cross-sectional view corresponding to the arrow AA in FIG. 1 of the flat string holding device 3 to which the flat string 4 is fixed, and FIG. 6 is a cross-sectional view corresponding to the arrow BB in FIG. 1 in the same state.
First, the end of the flat string 4 passes through the lightening hole 41 and is placed near the positioning holes 36 and 36 in the claw forming portion 13. The flat string 4 is pressed toward the claw portion 18. This pressing operation may be omitted. The flat string holding device 3 (male member 1) is folded in half from the bent portion 14 with the claw 22 inside. The two folds are made such that the two positioning protrusions 44 and 44 fit into different ones of the two positioning holes 36 and 36, respectively.

押圧部１５は、その２つの係合部４９がそれぞれ爪形成部１３の鍵部１９に重ねられ、鍵部１９が係止部３２を通過するまで爪形成部１３に押しつけられる。鍵部１９は、係止部３２通過時に幅方向外方に開き、通過後にその係合面５２が係止部３２の係止面３３に当たる。このことにより、平紐保持装置３（雄部材１）は、平紐４を挟んだ状態で二つ折りが安定に維持される。なお、爪形成部１３の各爪２２は、この状態で、押圧部１５のそれぞれ異なる爪収容孔４６に重なる。 The pressing portion 15 is pressed against the claw forming portion 13 until the two engaging portions 49 are overlapped with the key portion 19 of the claw forming portion 13 and the key portion 19 passes through the locking portion 32. The key portion 19 opens outward in the width direction when passing through the locking portion 32, and the engaging surface 52 of the key portion 19 contacts the locking surface 33 of the locking portion 32 after passing. As a result, the flat string holding device 3 (male member 1) is stably maintained in a folded state with the flat string 4 sandwiched therebetween. In addition, each nail | claw 22 of the nail | claw formation part 13 overlaps with the respectively different nail | claw accommodation hole 46 of the press part 15 in this state.

上述したように、平紐保持装置３への平紐４の固定作業は、肉抜き孔４１を通過させた平紐４の端部分を爪部１８に載せ、平紐保持装置３を二つ折りにして押圧部１５を爪形成部１３に押しつけて終了する。この作業では、平紐４を複雑に変形させる必要がないため、容易に平紐保持装置３への平紐４の固定を行うことができる。
平紐保持装置３による平紐４の一体化は、それぞれの爪２２の先が平紐４の糸の間を貫いて爪収容孔４６に入り込むことにより、または爪２２が平紐４を爪収容孔４６に押し入れることにより行われる。爪２２は、平紐４の糸の間を貫く場合にはその多くの部分が、平紐４を爪収容孔４６に押し入れる場合にはその先端部分が爪収容孔４６に入り込む。その結果、平紐４が引っ張られても爪２２の変形（引っ張り方向への傾斜）が爪収容孔４６により妨げられ押しつけが維持され、平紐４を強固に保持することができる。 As described above, the fixing operation of the flat string 4 to the flat string holding device 3 is performed by placing the end portion of the flat string 4 that has passed through the lightening hole 41 on the claw portion 18, folding the flat string holding device 3 in two, and the pressing portion 15. Is pressed against the nail forming portion 13 to finish. In this operation, since it is not necessary to deform the flat string 4 in a complicated manner, the flat string 4 can be easily fixed to the flat string holding device 3.
The flat cord 4 is integrated by the flat cord holding device 3 when the tip of each claw 22 penetrates between the threads of the flat cord 4 and enters the claw accommodation hole 46, or the claw 22 pushes the flat cord 4 into the claw accommodation hole 46. It is done by putting. Many portions of the claw 22 enter the claw accommodation hole 46 when the flat cord 4 is pushed into the claw accommodation hole 46 when passing between the threads of the flat cord 4. As a result, even if the flat string 4 is pulled, the deformation (inclination in the pulling direction) of the claw 22 is hindered by the claw receiving hole 46 and the pressing is maintained, and the flat string 4 can be firmly held.

また、平紐保持装置３は、折り曲げ部１４で二つ折りしたとき、台部２１の突出端面２６と爪収容部４５の突出端面５０との距離が平紐４の厚さよりも僅かに小さく設計され、押圧環４７が突出端面５０より高く突出する。そのため、一体化された平紐４は、突出端
面５０により爪形成部１３側に膨らんでから突出端面２６および突出端面５０に挟まれ、長手方向への移動が妨げられる。 Further, when the flat string holding device 3 is folded in two at the bent portion 14, the distance between the protruding end surface 26 of the base portion 21 and the protruding end surface 50 of the claw accommodating portion 45 is designed to be slightly smaller than the thickness of the flat string 4, The ring 47 protrudes higher than the protruding end surface 50. Therefore, the integrated flat string 4 is swelled by the protruding end surface 50 toward the claw forming portion 13 and then sandwiched between the protruding end surface 26 and the protruding end surface 50, and is prevented from moving in the longitudinal direction.

さらに、平紐保持装置３は、係合部４９の係合面５２が係止部３２の係止面３３に当接する状態で、いずれも内方に突出する帯状の第一挟持帯４２および帯状の第二挟持帯４８が重なるように形成されており、かつこの間が平紐４の厚さよりも若干小さく設計される。したがって、平紐保持装置３は、第一挟持帯４２および第二挟持帯４８が平紐４を挟み込むことによっても、平紐４を強固に連結することができる。 Further, the flat cord holding device 3 is configured such that the first and second belt-like sandwiching bands 42 project inward and the belt-like shape in a state where the engaging surface 52 of the engaging portion 49 is in contact with the engaging surface 33 of the engaging portion 32. The second holding band 48 is formed so as to overlap with each other, and this space is designed to be slightly smaller than the thickness of the flat cord 4. Therefore, the flat string holding device 3 can firmly connect the flat string 4 even when the first holding band 42 and the second holding band 48 sandwich the flat string 4.

The claw accommodation hole 46B has a wedge shape in a cross section that is orthogonal to the trapezoidal cross section and extends in the height direction of the trapezoidal cross section (for example, the claw accommodation hole 46B in FIG. 8). The wedge opening angle γ in the wedge-shaped cross section is designed to be not less than the inclination angle α of the inner surface 25B of the claw 22B to the outside and not less than 45 degrees and not more than 70 degrees.

爪収容孔４６Ｂにおける断面台形の斜辺が形成する角度ηは、爪２２Ｂの２つの側面２７Ｂ，２７Ｂが形成する角度βよりも大きい。また、爪収容孔４６Ｂにおける断面台形の下底の長さは、爪２２Ｂにおける台部２１Ｂとの連続部分における断面台形の下底の長さよりも大きい。爪収容孔４６Ｂにおいて断面台形の下底となる側面５１Ｂは、突出端面５０Ｂに対して直角である。 The angle η formed by the oblique side of the trapezoidal cross section in the claw receiving hole 46B is larger than the angle β formed by the two side surfaces 27B and 27B of the claw 22B.

図９は他の雄部材１Ｃの平面図、図１０は図９におけるＥ−Ｅ矢視断面図である。
雄部材１Ｃにおける平紐保持装置３Ｃは、爪部１８Ｃ、爪収容部４５Ｃおよび押圧環４７Ｃの形状等を除き、雄部材１Ｂにおけるものと同一の構成である。図９および図１０において、雄部材１Ｂにおけるものと同一の構成を有する部分については雄部材１Ｂと同一の符号を付し、その説明を省略する。 FIG. 9 is a plan view of another male member 1C, and FIG. 10 is a cross-sectional view taken along the line EE in FIG.
The flat string holding device 3C in the male member 1C has the same configuration as that in the male member 1B except for the shape of the claw portion 18C, the claw accommodating portion 45C, and the pressing ring 47C. 9 and 10, portions having the same configuration as that of the male member 1 </ b> B are denoted by the same reference numerals as those of the male member 1 </ b> B, and description thereof is omitted.

平紐保持装置３Ｃにおける爪部１８Ｃは、幅方向に並ぶ一対の爪３０Ｃ，３０Ｃの形状が、平紐保持装置３Ｂにおける幅方向に並ぶ一対の爪２２Ｂ，２２Ｂを有する爪部１８Ｂと異なる。平紐保持装置３Ｂでは、幅方向に並ぶ爪２２Ｂの外側面２４Ｂが、長手方向に拡がって底部１６Ｂに垂直であるのに対して、平紐保持装置３Ｃでは、幅方向に並ぶ爪３０Ｃは、底部１６Ｃに垂直な側面３７Ｃ（「垂直面３７Ｃ」という）が、折り曲げ部１４側を向いて幅方向に拡がっている。つまり、爪部１８Ｃは、９０度間隔で４つの爪２２Ｂ，３０Ｃ，２２Ｂ，３０Ｃを有し、いずれの爪２２Ｂ，３０Ｃ，２２Ｂ，３０Ｃも、その底部１６Ｂに垂直な外側面２４Ｂ，垂直面３７Ｃが幅方向（図９について上下）に拡がる。 The claw portion 18C in the flat cord holding device 3C is different from the claw portion 18B having a pair of claws 22B and 22B arranged in the width direction in the flat cord holding device 3B in the shape of the pair of claws 30C and 30C arranged in the width direction. In the flat string holding device 3B, the outer surface 24B of the claw 22B aligned in the width direction extends in the longitudinal direction and is perpendicular to the bottom portion 16B, whereas in the flat string holding device 3C, the claw 30C aligned in the width direction has the bottom portion 16C. A side surface 37C (referred to as “vertical surface 37C”) that is perpendicular to the surface extends toward the bent portion 14 in the width direction. That is, the claw portion 18C has four claws 22B, 30C, 22B, and 30C at intervals of 90 degrees, and any of the claws 22B, 30C, 22B, and 30C has an outer surface 24B and a vertical surface 37C that are perpendicular to the bottom portion 16B. Expands in the width direction (up and down in FIG. 9).

爪３０Ｃは、底部１６Ｃに平行な断面の形状が台形の錐状体（斜錐）である。この台形の形状は、外側の斜辺が上底および下底に直角に連なる。垂直面３７Ｃは、断面台形における長い方の底辺を形成する。垂直面３７Ｃに対向する側面は、折り曲げ部１４側に傾斜し、形状は二等辺三角形である。
爪３０Ｃにおける底部１６Ｃに平行な断面台形の爪部１８内方側の斜辺は、長手方向に対して角度θ傾斜する。雄部材１Ｃにおける角度θは２５度である。角度θは、２０度以上３５度以下が好ましい。 The claw 30C is a cone-shaped body (an oblique cone) having a trapezoidal cross-sectional shape parallel to the bottom portion 16C. In this trapezoidal shape, the outer hypotenuse is connected to the upper and lower bases at right angles. The vertical surface 37C forms the longer base of the trapezoidal cross section. The side surface facing the vertical surface 37C is inclined toward the bent portion 14, and the shape is an isosceles triangle.
The hypotenuse on the inner side of the claw portion 18 having a trapezoidal cross section parallel to the bottom portion 16C of the claw 30C is inclined at an angle θ with respect to the longitudinal direction. The angle θ in the male member 1C is 25 degrees. The angle θ is preferably 20 degrees or more and 35 degrees or less.

２つの爪３０Ｃ，３０Ｃの上記した特異な形状に伴い、底部１６Ｃから突出する台部２１Ｃの平面視における形状も、特異な環状形状の八角形である。台部２１Ｃの内方は、有底の第一孔２３Ｃである。
爪収容部４５Ｃは、平面視において台部２１Ｃと略同じ大きさ、若干大きな八角形の形状で突出する。爪収容部４５Ｃの突出端面５０Ｃは、全体として平面である。爪収容部４５Ｃは、外形八角形における幅方向に対向する辺の直近の内側に爪収容孔５４Ｃ，５４Ｃ、およびこの対向方向に直交して対向する２つの辺の直近の内側に爪収容孔４６Ｂ，４６Ｂを備える。爪収容孔４６Ｂ，４６Ｂは、平紐保持装置３Ｂにおける長手方向に並ぶ一対の爪収容孔４６Ｂ，４６Ｂと同じものである。 Along with the above-described unique shapes of the two claws 30C, 30C, the shape of the base portion 21C protruding from the bottom portion 16C is also a unique annular octagon. The inner side of the base portion 21C is a bottomed first hole 23C.
45C of nail | claw accommodating parts protrude in the substantially same magnitude | size as the base part 21C in planar view, and a slightly large octagon shape. The protruding end surface 50C of the claw receiving portion 45C is a flat surface as a whole. The claw receiving portion 45C has claw receiving holes 54C, 54C on the inner side immediately adjacent to the side facing the width direction in the outer octagon, and the claw receiving hole 46B on the inner side immediately adjacent to the two sides facing each other perpendicular to the facing direction. , 46B. The claw accommodation holes 46B and 46B are the same as the pair of claw accommodation holes 46B and 46B arranged in the longitudinal direction in the flat string holding device 3B.

爪収容孔５４Ｃは、平面視の開口形状が、斜辺の一方が両底辺に直交する台形であり、直交する斜辺が、爪収容部４５Ｃの台形の辺の一つに重なる。爪収容孔５４Ｃの台形である開口形状の長い方の底辺は、折り曲げ部１４側に位置し、この底辺に該当する側面（垂直面）５５Ｃは、突出端面５０Ｃに直交する。
爪収容孔５４Ｃは、爪収容孔４６Ｂと同様に、深くなるに伴い、断面台形における下底の長さを維持したまま、台形の高さが低くなる。したがって、爪収容孔５４Ｃは、台形断面の底辺に直交し断面台形の高さ方向に拡がる断面における形状が楔形である
爪収容部４５Ｃは、位置決め突起４４，４４が位置決め孔３６，３６に重なるように折り曲げ部１４で折り曲げられたときに、爪部１８Ｃに重なる。また、このとき、爪２２Ｃ
，２２Ｃの先端近傍は互いに異なる爪収容孔４６Ｃ，４６Ｃに収容され、爪３０Ｃ，３０Ｃの端近傍は互いに異なる爪収容孔５４Ｃ，５４Ｃに収容される。 The claw accommodation hole 54C has an opening shape in a plan view, in which one of the oblique sides is a trapezoid in which one of the oblique sides is orthogonal to both bottom sides, and the orthogonal oblique side overlaps one of the trapezoidal sides of the claw accommodation portion 45C. The long base of the opening shape which is a trapezoidal shape of the claw receiving hole 54C is located on the bent portion 14 side, and the side surface (vertical surface) 55C corresponding to the base is orthogonal to the protruding end surface 50C.
As the claw accommodation hole 54C becomes deeper as the claw accommodation hole 46B, the height of the trapezoid becomes lower while maintaining the length of the lower base in the trapezoidal cross section. Therefore, the claw receiving hole 54C has a wedge shape in a cross section extending in the height direction of the trapezoidal cross section perpendicular to the bottom of the trapezoidal cross section, so that the positioning projections 44 and 44 overlap the positioning holes 36 and 36. When it is bent at the bent portion 14, it overlaps the claw portion 18C. At this time, the claw 22C
, 22C are accommodated in different claw receiving holes 46C, 46C, and the vicinity of the ends of the claws 30C, 30C are accommodated in different claw receiving holes 54C, 54C.

押圧環４７Ｃは、爪収容部４５Ｃの外側を囲んで爪収容部４５Ｃよりも高く突出し、突出端は平面である。
平紐保持装置３Ｃは、３つの爪２２Ｂ，３０Ｃ，３０Ｃにおける底部１６Ｂ，１６Ｃに垂直な側面（外側面２４Ｂ、垂直面３７Ｃ，３７Ｃ）が凸部２側を向く。そして、平紐保持装置３Ｃは、平紐４を保持したとき、これら（外側面２４Ｂ、垂直面３７Ｃ，３７Ｃ）が、爪収容孔４６Ｂ，爪収容孔５４Ｃ，５４Ｃにおける突出端面５０Ｃに直交する側面５１Ｂ、垂直面５５Ｃ，５５Ｃに対向する。 The pressing ring 47C surrounds the outside of the claw receiving portion 45C and protrudes higher than the claw receiving portion 45C, and the protruding end is a flat surface.
In the flat string holding device 3C, the side surfaces (outer surface 24B, vertical surfaces 37C, 37C) perpendicular to the bottom portions 16B, 16C of the three claws 22B, 30C, 30C face the convex portion 2 side. When the flat string holding device 3C holds the flat string 4, these (outside surface 24B, vertical surfaces 37C, 37C) are side surfaces 51B orthogonal to the protruding end surfaces 50C of the claw receiving holes 46B and the claw receiving holes 54C, 54C, Opposite the vertical surfaces 55C and 55C.

平紐保持装置３Ｃは、平紐４が凸部２とは反対側に引っ張られたとき、爪２２Ｂ，３０Ｃ，３０Ｃの変形が側面５１Ｂ、垂直面５５Ｃ，５５Ｃに妨げられて爪２２Ｂ，３０Ｃ，３０Ｃが平紐４を保持し続け、強固に平紐４を一体化する。
平紐保持装置３，３Ｂ，３Ｃにおける爪２２，２２Ｂ，３０Ｃに換えて、正四角錐を含む所謂四角錐、三角錐、五角錐等の角錐、または円錐、楕円錐等の他の形状の錐状体を用いることができる。これら正四角錐等は、底部１６，１６Ｂ，１６Ｃに垂直な外側面２４Ｂ等を有しないため、爪２２，２２Ｂ，３０Ｃに比べて単独では平紐４の引っ張りに対する抵抗がやや劣る。しかし、爪収容孔と組み合わせることにより正四角錐等の形状の爪を備えた平紐保持装置は、実用に十分な保持強度を有する。 In the flat cord holding device 3C, when the flat cord 4 is pulled to the side opposite to the convex portion 2, the deformation of the claws 22B, 30C, 30C is prevented by the side surface 51B, the vertical surfaces 55C, 55C, and the claws 22B, 30C, 30C The flat string 4 is continuously held and the flat string 4 is firmly integrated.
Instead of the claws 22, 22B, 30C in the flat cord holding devices 3, 3B, 3C, so-called quadrangular pyramids including triangular pyramids, triangular pyramids, pentagonal pyramids, etc., or cones having other shapes such as cones, elliptical cones, etc. Can be used. Since these regular quadrangular pyramids and the like do not have the outer surface 24B perpendicular to the bottom portions 16, 16B, 16C, etc., the resistance to pulling of the flat cord 4 is somewhat inferior compared to the claws 22, 22B, 30C alone. However, the flat string holding device provided with a claw shaped like a regular quadrangular pyramid by combining with the claw receiving hole has a holding strength sufficient for practical use.

その他、平紐保持装置３，３Ｂ，３Ｃ、および平紐保持装置３，３Ｂ，３Ｃの各構成または全体の構造、形状、寸法、個数、材質などは、本考案の趣旨に沿って適宜変更することができる。 In addition, each structure of the flat string holding devices 3, 3B, 3C and the flat string holding devices 3, 3B, 3C or the overall structure, shape, dimensions, number, material, and the like may be appropriately changed in accordance with the spirit of the present invention. it can.

本考案は、社員証、ＩＤカード等を保持するネックストラップにおけるストラップ（平紐）の端を保持するための平紐保持装置に利用することができる。 The present invention can be used for a flat cord holding device for holding an end of a strap (flat cord) in a neck strap for holding an employee ID card, an ID card or the like.
