Description

【０００１】
【発明の属する技術分野】
本発明は、紐留め具のうち、特に洋服や袋体等に配置される引帯や引紐或いはコード紐（以下、これらを紐と称する）を引き抜き方向の力に抗して係止する紐留め具に関するものである。
【０００２】
【従来の技術】
図１０は従来の紐留め具（実公昭６４−９２号）を示している。この紐留め具５０は、本体がブロック状をなし、空間部５１を介し区画形成された左右の通し孔５２ａ付の支持部５２と、各支持体５２の下部に連結されて切欠部５３ａ，５３ｂの存在により弾性変形可能な連結体５４と、空間部５１内に位置して連結体５４の上面から突設されて上方に延びる押圧体５５とを備えている。押圧体５５は、上面から下側に向けて縦穴部５６を形成しており、前記各通し孔５２ａに挿通される紐６０の途中部分６０ａを縦穴部５６の底面５６ａで受ける構成である。使用する際は、図１０（ａ）の如く押圧体５５を下向きに押して通し孔５０ａと縦穴部５６とが連続する状態にし、洋服等に配置された紐６０の端部を一方通し孔５０ａ、縦穴部５６、他方の通し孔５０ａに挿通した後、前記押圧体５５の押圧を解放する。すると、押圧体５５が同（ｂ）の如く連結体５４の弾性復帰力により元の状態になる。これにより、紐６０は、両通し孔５０ａの間にある途中部分６０ａが縦穴部５６の底面５６ａで持ち上げられ抜け止め係止される。この係止力は底面５６ａが通し孔５０ａより離れるほど大きくなる。
【０００３】
【発明が解決しようとする課題】
上記した紐留め具は、例えば、特開２０００−１８４９０６号に開示されるような従来構造に対し部材数が最小限であるという利点を有しているものの、次のような点で未だ充分満足できない。即ち、この構造では、押圧体５５、連結体５４、切欠部５３ａ，５３ｂが共に高さ方向に配置されるため縦に長いブロック状となる。このため、本体が洋服に取り付けられる使用態様において、取付面からの張出量が大きく、邪魔になったり、デザインを損ねる。また、この構造では、押圧体５５の弾性変位量が連結体５４の肉厚や切欠部５３ａ，５３ｂの大きさ等に比例するため、紐６０に対する係止力をより強くしようとすると切欠部５３ａ，５３ｂを大きくしなくてはならず、本体が自ずと大きくなる。しかも、押圧体５５は空間部５１から突出した上面５５ａを指で押す構成であり、操作性からは該上面５５ａをある程度大きくしなくてはならずそれに伴って全体も大きくなる。同時に、本体が洋服に取り付けられる使用態様では、押圧体５５を押し操作し難くいこと、押圧体５５の押し力が人体にそのまま伝わり易いこと等の問題がある。
【０００４】
本発明は以上の課題を一掃すべく開発されたものである。その目的は、単一部材からなるタイプにおいて、洋服等へのフィット性、紐に対する係止力、小型化、操作性共に従来品より数段優れた紐留め具を実現することにある。
【０００５】
【課題を解決するための手段】
上記目的を達成するため請求項１の本発明は、図１〜図４の例で特定すると、洋服等に配置された紐１０の端部を該紐１０の引き抜き方向の力に抗して任意の位置に係止する紐留め具１において、前記洋服等に取り付けられる略平板状のベース部２と、前記ベース部２上に所定間隔を保って対に突設された通し孔６付の縦壁部３と、前記ベース部２上から前記両縦壁部３の間に片持ち状に突設されて、揺動端側が前記縦壁部３の通し孔６よりも上側に変位しているとともに、前記両縦壁部の各通し孔に挿通される紐の途中部分を導く略Ｕ形の受け部を有し、前記両縦壁部の各通し孔６に挿通される紐１０を垂直方向へ変位させて係止する弾性押圧片部４とを一体に形成しており、前記押圧片部４が、前記縦壁部３の各通し孔６に挿通される紐１０の途中部分を、前記受け部４ｃに掛けて前記各縦壁部３の通し孔６との間に生じるせん断力により係止することを特徴としている。
また、請求項２の本発明は、請求項１の『略Ｕ形の受け部４ｃ』を、『頸状の受け部１４ｃ』に変更しものであり、図２〜図８の例で特定すると、洋服等に配置された紐１０の端部を該紐１０の引き抜き方向の力に抗して任意の位置に係止する紐留め具１１において、前記洋服等に取り付けられる略平板状のベース部１２と、前記ベース部１２上に所定間隔を保って対に突設された通し孔１６付の縦壁部１３と、前記ベース部１２上から前記両縦壁部１３の間に片持ち状に突設されて、揺動端側が前記縦壁部３の通し孔６よりも上側に変位しているとともに、前記両縦壁部１３の各通し孔１６に挿通される紐１０の途中部分を導く頸状の受け部１４ｃを有し、前記両縦壁部の各通し孔１６に挿通される紐１０を垂直方向へ変位させて係止する弾性押圧片部１４とを一体に形成しており、前記押圧片部１４が、前記縦壁部１３の各通し孔１６に挿通される紐１０の途中部分を、前記受け部１４ｃに掛けて前記各縦壁部１３の通し孔１６との間に生じるせん断力により係止することを特徴としている。
【０００６】
以上の各発明は従来構造の欠点を次のような工夫により解消したものである。即ち、この構造特徴は、第1形態の場合だと、略平板状のベース部２を主体とし、該ベース部上に紐１０を挿通する縦壁部３及び弾性押圧片部４を付設した点にある。これは、まず、平板状のベース部２を使用箇所である洋服等へ当てて形態例の如く縫製や両面接着テーブ等により容易に取り付けることを可能にする。同時に、本発明品は、使用状態において、従来と同じく押圧部片部４を押し操作することにより洋服類に配置された紐１０を使用者の好みに応じ該紐１０の端部の引出量を適宜に変更する。その際、押圧片部４を押したときの押し力が平板状のベース部２に加わり、該面的に広いベース部２から人体に受けるため人体に加わる応力を従来品よりも分散して小さくできる。加えて、この種紐留め具の張出寸法は、本体下面から押圧部（図６の押圧体や図１の押圧片部等）の突出高さにより決まる。本発明品は、押圧片部４を平板状のベース部上から突出することにより、又、押圧片部と両縦壁部とを同じベース部上に設けることにより、全体の高さを抑えてコンパクト化を実現容易にする。同時に、押圧片部４の全体がベース部２上に露出されているため、押圧面積を増大し易く指で押すときの操作性も良好にする。
【０００７】
また、請求項１の押圧片部４は、前記ベース部２に片持ち状に設けられ、前記両縦壁部３の各通し孔６に挿通される紐１０の途中部分１０ａを導く略Ｕ形の受け部４ｃを揺動端側に有している構成、又は、請求項２の押圧片部１４は、前記ベース部１２に片持ち状に設けられ、前記両縦壁部１３の各通し孔１６に挿通される紐１０の途中部分１０ａを導く頸状の受け部１４ｃを揺動端側に有している構成である。これは、押圧片部４や１４がベース部２や１２上に露出された状態となる関係で、両縦壁部３や１３の各通し孔６や１６に挿通される紐１０の途中部分１０ａが不用意に外れないようにする紐ガイド作用と、前記紐１０の途中部分１０ａを略Ｕ形や頸状に嵌合し押圧片部４や１４の外面から張り出さないようにしたり一体感を得る外観処理作用とを得ることに意義がある。
同時に、前記押圧片部４や１４は揺動端側が前記通し孔６や１６よりも上側に変位しており、前記各通し孔６や１６に挿通される紐１０の途中部分１０ａを、前記受け部４ｃや１４ｃに掛けた状態で前記各縦壁部３や１３の通し孔６や１６との間に生じるせん断力により係止する構成である。これは本発明の紐係止作用を確認的に特定したものである。
以上の各発明は次のように具体化されることがより好ましい。即ち、前記両縦壁部３や１３は略コ形状の両辺部分として形成される一方、前記押圧片部４や１４は前記コ形状の両辺部分３ａや１３ａの内側に斜め上向きに設けられて、揺動端側が前記コ形状の中間辺部分３ｂや１３ｂに接近して斜め下向きに折り曲げられている構成である（請求項３）。両縦壁部３や１３の形状は、コ形状の中間辺部分３ｂや１３ｂの存在により、剛性を持たせて縦壁部３や１３等を薄くすることを容易にし、又、各通し孔６や１６に挿通される紐１０の途中部分１０ａをコ形状の中間辺部分３ｂや１３ｂの内側に位置させて多少なりとも見えなくする利点がある。押圧片部４や１４の形状は、斜め上向きにすることにより押圧操作性を良好にし、又、揺動端側を斜め下向きに折り曲げることにより高さを抑えて弾性能を大きくできる等の利点がある。
【０００８】
【発明の実施の形態】
以下、本発明の２つの実施形態を図面に基づいて説明する。図１〜図４は第１形態に係る紐留め具を示し、図５〜図８は第２形態の紐留め具を示している。このうち、図１と図５は各形態の紐留め具の概略外観図、図２及び図６の各（ａ），（ｂ）は各紐留め具の正面及び背面図である。図３は図１の紐留め具の細部を示し、同（ａ）は図２（ａ）のＡ−Ａ線断面図、同（ｂ）はＢ−Ｂ線断面図、同（ｃ）はＣ−Ｃ線断面図である。図７は図５の紐留め具の細部を示し、同（ａ）は側面図、同（ｂ）は図６（ａ）のＤ−Ｄ線断面図、同（ｃ）はＥ−Ｅ線断面図である。図４と図８は各形態の紐留め具の作用例を示し、図９は各形態の紐留め具の使用例を示している。以下の説明では、本発明の基本思想を第１形態の例で詳述し、第２形態により補足事項を含めて言及する。
【０００９】
（第１形態）この紐留め具１は、樹脂成形品からなり、ベース部２を主体とし、該ベース部２上に一体に形成された対の縦壁部３，３及び弾性押圧片部４を有している。なお、紐留め具１は作図上拡大しているが、例えば、この紐留め具１が一般的な洋服に用いられる場合、ベース部２の最大幅が３０〜１５ｍｍ、押圧片部４の最大突出高さが１５〜３ｍｍ程度の小さなものである。
【００１０】
このベース部２は、横に長い略矩形の平板状をなし、両側に貫通形成された取付孔２ａと、左右中間部にあって両縦壁部３，３の間を大きく欠如した切欠部５とを有している。本発明のベース部２は、形態例の如く平板状でかつ切欠部５等を付設することにより、洋服等の平面部に対し面当接し易くすることが好ましい。形状的には円形や楕円、多角形であってもよいが、形態例の如く板厚を薄くすると共に矩形角部に丸味を付けることにより、使用状態での違和感を生じないように処理される。各取付孔２ａは長孔に形成されており、洋服等の平面部に縫製により取付可能にしている。但し、ベース部２は、取付孔２ａを省略し、又は、省略せずに両面接着テープ等を介し被取付部に取り付けてもよい。
【００１１】
両縦壁部３は、ベース部２上にあって、各取付孔２ａの内側から片側縁部に沿って略コ形の立壁を突設し、該コ形状の両辺部分３ａ，３ａにより構成されている。形状的には、コ形の中間辺部分３ｂ側が少し高く、両辺部分３ａの端側が低くなっている。そして、この形態では、両縦壁部３がコ形の中間辺部分３ｂで接続されており、前記した切欠部５が両辺部分３ａと中間辺部分３ｂの内側に位置している。各縦壁部３には通し孔６が対向して設けられている。この通し孔６は、紐１０を余裕を持って挿通する貫通孔であればよい。この形態では、縦壁部３のうちコ形の中間辺部分３ｂ側にあって、図２（ｂ）等の如くベース部２の一部を含んで切欠部５上に位置し、また、孔上側に丸味が付けられている。
【００１２】
押圧片部４は、図３の如くベース部２から斜め上向きに突出されて、全体が前記切欠部５の存在により上と下側から見える状態に設けられている。即ち、弾性押圧片部４は、基部４ａをコ形の中間辺部分３ｂと対向したベース部２の対応部分に結合し、中間部を切欠部５上に位置して斜め上向きに突出している。また、先端付近つまり揺動端４ｂ側は、下向きに折り曲げられていると共に、断面Ｕ形の受け部４ｃに形成されている。受け部４ｃは、コ形の中間辺部分３ｂに接近していて、押圧片部４の通常状態つまり上から押されていない状態で少なくとも前記各通し孔５よりも上側に変位していることが必須となる。また、受け部４ｃは、押圧片部４が下向きに押圧されると、その受け面が各通し孔６と略横並び可能になっている。
【００１３】
（第２形態）この紐留め具１１も樹脂成形品であり、ベース部１２を主体とし、該ベース部１２上に突設された対の縦壁部１３，１３及び弾性押圧片部１４を有している。なお、設計的には、図９に例示した如く、前記第１形態のものが洋服類に対し横向き配置を想定しているのに対し、第２形態のものが縦向き配置を想定している。
【００１４】
このベース部１２は、上下に長い略矩形の平板状をなし、下側に貫通形成された取付孔１２ａと、左右中間部にあって両縦壁部１３，１３の間を大きく欠如した切欠部１５とを有している。形状的要件は上記したベース部２と同じであり、また洋服等の平面部に取付孔１２ａを介し縫製により取付可能にしている。この場合も取付孔１２ａを省略し、両面接着テープ等を介して被取付部に取り付けることも可能である。要は、取付孔２ａや取付孔１２ａは縫製により取り付ける態様のときに利用される。
【００１５】
両縦壁部１３は、ベース部１２上にあって、両側から上側縁部に沿って略コ形の立壁を突設し、該コ形状の両辺部分１３ａ，１３ａにより構成されている。形状的には、コ形の中間辺部分１３ｂ側が少し高く、両辺部分１３ａの下側が低くなっている。そして、この形態では、両縦壁部１３がコ形の中間辺部分１３ｂで接続されている点、前記切欠部１５が両辺部分１３ａと中間辺部分１３ｂの内側に位置している点、通し孔１６が各縦壁部１３に対向して設けられている点、該通し孔１６が縦壁部１３のうちコ形の中間辺部分１３ｂ側にあって、図６（ｂ）等の如くベース部１２の一部を含んで切欠部１５上に位置している点、等について第１形態と同じくしている。但し、この中間辺部分１３ｂは図７（ｂ）の如く下側が欠如されて片状に形成されている。このような、コ形の中間辺部分３ｂや１３ｂは、ベース部２や１２、縦壁部３や１３の各剛性を補強するリブ作用と、押圧片部４や１４を下向きへ過大に押したとしても紐１０の対応部つまり途中部分１０ａがここに当たって必要以上下へ落ち込まないようにする係止作用、外観的な見栄え処理作用を兼ねる。
【００１６】
弾性押圧片部１４は、図７の如くベース部１２から斜め上向きに突出されて、全体が切欠部１５の存在により前後側から見える状態に設けられている。即ち、押圧片部１４は、基部１４ａをコ形の中間辺部分１３ｂと対向したベース部１２の対応部分に結合し、中間部を切欠部１５上に位置して斜め上向きに突出している。先端付近つまり揺動端１４ｂ側は、下向きに折り曲げられていると共に、板両側から一部欠如した頸状の受け部１４ｃに形成されている。この受け部１４ｃは、第１形態と同じくコ形の中間辺部分１３ｂに接近していて、押圧片部１４の通常状態つまり上から押されていない状態で少なくとも前記各通し孔１６よりも上側に変位していることが必須となる。また、受け部１４ｃは、押圧片部１４が下向きに押圧されると、その受け部１４ｃの頸状部分が各通し孔１６と略横並び可能になっている。
【００１７】
このような受け部１４ｃは、第１形態の受け部４ｃに対し紐１０の対応部、つまり途中部分１０ａが頸状の凹欠箇所に位置規制されるため不用意な外れをより確実に防ぐことができる点で優れている。これに対し、第１形態の受け部４ｃは、本発明品の使用態様において、図４（ｃ）の如く紐１０の端部を矢印Ｙ方向へ更に引き出したいとき、押圧片部４を指で押し下げるだけで調整可能になる点で優れている。受け部１４ｃの場合には、押圧片部１４を同様に押し下げただけでは紐１０の端部を引き出し難く、図８（ｂ）の如く上流側の通し孔１６から途中部分１０ａを一旦必要長さだけ引き出した後、紐１０の端部を引っ張って下流側の通し孔１６つまり同図の矢印Ｙ方向へ引き出すことになる。
【００１８】
（使用例）図９は以上の各形態の紐留め具１や１１を衣類に取り付けた使用例である。この衣類は、頸回りと胴回りにそれぞれ紐１０を配置しており、符号Ｘ1の頸回りに上記紐留め具１を取り付け、符号Ｘ2の胴回りに上記紐留め具１１を取り付けた例である。各紐留め具１や１１は、それぞれの紐１０の両端引き出し口に対応して縫製又は両面接着テープ等にて取り付けられている。このように、本発明品は、衣類や洋服等に取り付けた状態で使用されることを前提としている。紐１０は、図９の使用例の如く両端が自由端となっている態様に限らず、一方端部が衣類や洋服等に固定されることもある。前者では本発明品が１本の紐１０に対し２個使用される。後者では１本の紐１０に対し１個使用されることになる。
【００１９】
以上の各紐留め具１，１１は紐１０の抜け止め又は係止作用的に同じ。この点を第１形態の図４で説明する。紐１０は、一方の通し孔６から他方の通し孔６に通されると共に、途中部分１０ａが押圧片部４の受け部４ｃで受け止められた状態で各通し孔６より上側へ変位している。紐１０に対する係止力は、その上側変位に基づく各縦壁部３と押圧片部４との間のせん断力を利用している点で従来と同じ。なお、本発明品では、途中部分１０ａの両側つまり各通し孔６に向かう部分が図４（ｃ）の如く受け部４ｃの両側と対応縦壁部３との間に挟み込まれた状態にし易く、前記せん断力をその挟み込みにより安定保持したり、補強することも可能となる。
【００２０】
なお、本発明の紐留め具は、請求項で特定される構成要素を備えておればよく、例えば、通し孔６や１６の大きさ及び形状等は紐１０の断面形状に応じ変形される。また、ベース部２や１２としては洋服類に取り付け易くなるよう平板状であればよい。該平板状には切欠部５や１５を有している形態も当然に含まれるものである。
【００２１】
【発明の効果】
以上説明した通り、本発明に係る紐留め具は、略平板状のベース部上に紐を挿通する縦壁部及び弾性押圧片部を付設したことから、使用箇所である洋服等への取付性、押圧片部を押したときの押し力がベース部で分散されるため人体に加わる応力を小さくできる。また、押圧片部と両縦壁部とを同じ平板状のベース部上に設けることにより、全体の高さを抑えてコンパクト化を実現でき、同時に、押圧片部の押圧面積を増大して操作性を良好にできる。このように、本発明品は、従来品に対し使い勝手及び品質的に優れ、適用上の制約をなくしてその用途を拡大できる。

BACKGROUND OF THE INVENTION
The present invention relates to a string clamp that locks a strap, a draw string, or a cord string (hereinafter referred to as a string), which is arranged on a clothes, a bag, or the like, against a force in a pulling direction. It relates to ingredients.
[0002]
[Prior art]
FIG. 10 shows a conventional string fastener (Japanese Utility Model Publication No. 64-92). The string fastener 50 has a main body in a block shape, and is connected to a support portion 52 with left and right through holes 52a partitioned through a space portion 51, and lower portions of the support bodies 52 to be cut out portions 53a and 53b. And a pressing body 55 that is located in the space 51 and protrudes from the upper surface of the connecting body 54 and extends upward. The pressing body 55 has a configuration in which a vertical hole portion 56 is formed from the upper surface to the lower side, and a middle portion 60a of the string 60 inserted through each through hole 52a is received by the bottom surface 56a of the vertical hole portion 56. When used, the pressing body 55 is pushed downward as shown in FIG. 10 (a) so that the through hole 50a and the vertical hole portion 56 are continuous, and the end portion of the string 60 disposed in the clothes or the like is connected to the one through hole 50a, After passing through the vertical hole 56 and the other through hole 50a, the pressing of the pressing body 55 is released. Then, the pressing body 55 is restored to the original state by the elastic restoring force of the connecting body 54 as shown in FIG. As a result, the middle portion 60a between the through holes 50a of the string 60 is lifted by the bottom surface 56a of the vertical hole portion 56, and is retained and locked. This locking force increases as the bottom surface 56a moves away from the through hole 50a.
[0003]
[Problems to be solved by the invention]
Although the above-described string fastener has an advantage that the number of members is minimal with respect to a conventional structure as disclosed in, for example, Japanese Patent Laid-Open No. 2000-184906, it is still sufficiently satisfactory in the following points. Can not. That is, in this structure, since the pressing body 55, the connecting body 54, and the cutout portions 53a and 53b are all arranged in the height direction, the block has a vertically long block shape. For this reason, in the usage mode in which the main body is attached to the clothes, the amount of overhang from the attachment surface is large, which may interfere with the design. Further, in this structure, the elastic displacement amount of the pressing body 55 is proportional to the thickness of the coupling body 54, the size of the notches 53a and 53b, and so on. , 53b must be enlarged, and the main body naturally becomes larger. Moreover, the pressing body 55 is configured to press the upper surface 55a protruding from the space 51 with a finger, and the upper surface 55a must be enlarged to some extent from the viewpoint of operability, and the entire size is increased accordingly. At the same time, in the usage mode in which the main body is attached to the clothes, there are problems that it is difficult to push the pressing body 55 and that the pressing force of the pressing body 55 is easily transmitted to the human body.
[0004]
The present invention has been developed to eliminate the above problems. The purpose is to achieve a string fastener that is several steps better than conventional products in terms of fit to clothes, locking force on the string, miniaturization, and operability in a single member type.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention of claim 1 , as specified in the examples of FIGS. 1 to 4, the end portion of the string 10 arranged on clothes or the like can be arbitrarily resisted against the force in the pulling direction of the string 10. In the string fastener 1 to be locked at the position, a substantially flat base portion 2 attached to the clothes and the like, and a vertical hole with a through hole 6 projecting in pairs on the base portion 2 at a predetermined interval. The wall 3 and the base 2 are projected in a cantilever manner between the vertical walls 3 and the swing end side is displaced above the through hole 6 of the vertical wall 3. And a substantially U-shaped receiving portion that guides a middle portion of the string inserted into the through holes of the vertical wall portions, and the string 10 inserted into the through holes 6 of the vertical wall portions in the vertical direction. The elastic pressing piece portion 4 that is displaced and locked is integrally formed, and the pressing piece portion 4 is inserted into each through hole 6 of the vertical wall portion 3. The middle portion of 0, is characterized by locking by shearing force generated between the through-holes 6 of the respective vertical wall portions 3 over the receiving portion 4c.
Further, in the present invention of claim 2, the “substantially U-shaped receiving portion 4c” of claim 1 is changed to a “cervical receiving portion 14c”, which is specified in the examples of FIGS. A substantially flat base portion attached to the clothes or the like in the string fastener 11 that locks the end of the string 10 arranged on the clothes or the like at an arbitrary position against the force in the pulling direction of the string 10. 12 and a vertical wall portion 13 with a through hole 16 projecting in pairs on the base portion 12 at a predetermined interval, and a cantilever between the vertical wall portion 13 and the base portion 12. The swing end side is displaced upward from the through hole 6 of the vertical wall portion 3 and is guided along the middle portion of the string 10 inserted through the through holes 16 of the vertical wall portions 13. It has a neck-shaped receiving part 14c, and the string 10 inserted through the through holes 16 of both the vertical wall parts is displaced in the vertical direction and locked. The pressing piece portion 14 is formed integrally with the pressing piece portion 14 so that the middle portion of the string 10 inserted into each through hole 16 of the vertical wall portion 13 is hung on the receiving portion 14c. It is characterized by being locked by a shearing force generated between the vertical wall portions 13 and the through holes 16.
[0006]
Above the inventions of those which overcomes disadvantages of the prior structure by following contrivance. That is, this structural feature is that in the case of the first embodiment, the base portion 2 is mainly a flat plate, and the vertical wall portion 3 through which the string 10 is inserted and the elastic pressing piece portion 4 are provided on the base portion. It is in. This allows the flat base portion 2 to be applied to clothes or the like where it is used and easily attached by sewing, double-sided adhesive tape, or the like as in the embodiment. At the same time, the product of the present invention, in the state of use, pushes the pressing piece piece 4 in the same manner as in the prior art, so that the string 10 placed on the clothes can be pulled out at the end of the string 10 according to the user's preference. Change as appropriate. At that time, the pressing force when the pressing piece 4 is pressed is applied to the flat base portion 2, and the human body receives the stress from the wide base portion 2 so that the stress applied to the human body is dispersed and smaller than that of the conventional product. it can. In addition, the overhang dimension of the seed string fastener is determined by the protruding height of a pressing portion (such as the pressing body in FIG. 6 or the pressing piece portion in FIG. 1) from the lower surface of the main body. The product of the present invention suppresses the overall height by projecting the pressing piece portion 4 from the flat base portion, and by providing the pressing piece portion and both vertical wall portions on the same base portion. Make it easier to achieve compactness. At the same time, since the entire pressing piece portion 4 is exposed on the base portion 2, the pressing area is easily increased and the operability when pressing with a finger is also improved.
