201242734 體及墊圈被安裝於布料時，藉由來自第1孔眼模側相對性 地被推壓’而能夠分別獨立且彈性位移在第1孔眼模將第 2孔眼模相對性地予以推壓的方向上，上述第2孔眼模， 是包括用以限制上述軸部的彈性位移之位移量的止擋。 在本發明中’在安裝有孔眼的「布料」，包括著紡織 品、布、無紡布、毛氈、皮革、樹脂片等。本發明的孔眼 安裝裝置’特別是’考量適用於對於安裝厚度〇.5mm以 下的布料的孔眼。 在本發明的孔眼安裝裝置中，一般，第1孔眼模是被 配置於上方’第2孔眼模是被配置於下方，第1孔眼模對 於第2孔眼模下降’惟並不是被限定於此，例如，也有第 2孔眼模是被配置於上方，第1孔眼模是被配置於下方， 且第1孔眼模對於第2孔眼模上昇的形態。又，在以下的 說明中’依據第1孔眼模是被配置於上方，第2孔眼模是 被配置於下方，第1孔眼模對於第2孔眼模下降的形態。 在本發明中，將孔眼本體保持於上方的第1孔眼模， 並將墊圈載置於下方的第2孔眼模，並將布料水平地配置 於孔眼本體與墊圏之間之後，將第1孔眼模朝向第2孔眼 模下降。藉此，首先，孔眼本體的孔柱部的前端將布料被 推壓至第2孔眼模的軸部的傾斜面，接下來，利用孔柱部 經由傾斜面將軸部推向下方，使得軸部朝下方彈性位移， 而在該軸部的下降中，實質上進行著孔眼本體的孔柱部的 前端所導致的布料的切斷、貫通。當軸部對於下方的位移 利用止擋被限制時，由第1孔眼模側利用推壓使得套筒部 201242734 朝下方彈性地移動，而在該套筒部的下降中，孔眼本體及 孔柱部的鉚接實質地進行。 在本發明的一實施形態中，上述軸部，是包括：具有 上述傾斜面之金屬性的軸部本體、及支承軸部本體的軸部 彈性體，上述套筒部，是包括：具有上述凹部之金屬性的 孔眼模套筒、及支承孔眼模套筒的套筒彈性體。做爲軸部 彈性體及套筒彈性體，可使用彈簧、橡膠等。又，套筒彈 性體者可設定成比軸部彈性體更容易變形。做爲其他形 態，套筒部的全體以彈性體可形成。 在本發明的一實施形態中，止擋，是與軸部同心狀地 被配置；軸部，是具備插入有該止擋的空洞；軸部，是利 用止擋及空洞被引導。止擋，是除了限制軸部朝向下方的 移動之外，還發揮做爲同心狀地移動軸部之導件的作用。 依照其他的本發明，提供一種孔眼安裝裝置，是用以 將孔眼本體的圓筒狀孔柱部從布料的一面側朝向另一面側 貫通，然後，插通於布料的另一面側的墊圈的穴部之後， 利用與墊圈一起鉚接，使孔眼本體及墊圈做爲孔眼來安裝 於布料所用的孔眼安裝裝置，其特徵爲：具備：第1孔眼 模、及第2孔眼模，該第1孔眼模，是保持孔眼本體，該 第2孔眼模，是用以保持墊圈，並與第1孔眼模同心狀地 配置，第1孔眼模或第2孔眼模，是可朝向第2孔眼模或 第1孔眼模同心狀地可移動，第2孔眼模，是包括：圓柱 狀軸部，與包圍軸部的圓筒狀套筒部，上述軸部，是具 有：承受孔眼本體的孔柱部的前端，並且使孔柱部朝半徑 -8 - 201242734 方向外側彎曲所用的環狀傾斜面，上述套筒部，是具有： 收容有比墊圈的上述穴部還要半徑方向外側部分的環狀凹 部，上述套筒部，是當孔眼本體及墊圈被安裝於布料，藉 由來自第1孔眼模側相對性地被推壓，而能夠彈性地位移 在第1孔眼模將第2孔眼模相對性地予以推壓的方向上， 上述軸部，是與墊圈的上述穴部的周緣可抵接。 在本發明中，墊圈的穴部周緣可抵接於第2孔眼模的 軸部，因比墊圈的穴部還要半徑方向外側部分被承受於第 2孔眼模的套筒部的凹部而抵接，因此，墊圈是被保持在 第2孔眼模的軸部與套筒部全面。所以，與如日本特開平 1-94801號公報所述的孔眼安裝裝置，僅以軸部支承墊圈 的情形相比較，藉由在孔眼本體的孔柱部的布料切斷或之 後的孔柱部的鉚接變形時，分別相對性地位移軸部與套筒 部，而可成爲適用第2孔眼模的動作。所以，可確實地進 行孔眼的安裝。 在本發明的一實施形態中，上述軸部，是當孔眼本體 及墊圈被安裝於布料時，藉由來自第1孔眼模側相對性地 被推壓，而能夠與上述套筒部獨立且彈性地位移在第1孔 眼模將第2孔眼模相對性地予以推壓的方向上。這時候， 在孔眼本體的孔柱部所導致的布料切斷或是之後的孔柱部 的鉚接變形時’能夠成爲軸部與套筒部最適用的動作。 又’依照另一本發明’提供一種孔眼安裝方法，是用 以將保持於第1孔眼模的孔眼本體的圓筒狀孔柱部從布料 的一面側朝向另一面側貫通之後，利用與布料的另一面側 201242734 的保持於第2孔眼模的墊圈一起鉚接，使孔眼本體及墊圈 做爲孔眼來安裝於布料所用的孔眼安裝方法，其特徵爲： 上述第2孔眼模，是包括：圓柱狀軸部，與包圍軸部的圓 筒狀套筒部，上述軸部，是具有：用以承受孔眼本體的孔 柱部的前端，並且將孔柱部朝半徑方向外側彎曲的環狀傾 斜面，第2孔眼模被來自第1孔眼模相對性地被推壓之 際，包括：軸部位移步驟、及套筒位移步驟，該軸部位移 步驟，是上述軸部彈性地位移於第1孔眼模將第2孔眼模 相對性推壓的方向，該套筒位移步驟，是在軸部位移步驟 之後，使上述套筒部朝上述方向彈性位移，在上述軸部位 移步驟中，使孔眼本體的孔柱部的前端一面將布料對軸部 的傾斜面相對性地推壓，並一面切斷布料。 在本發明中，將孔眼本體保持於上方的第1孔眼模， 並將墊圈載置於下方的第2孔眼模，且將布料水平地配置 於孔眼本體與墊圈之間之後，將第1孔眼模朝向第2孔眼 模下降。藉此，首先’孔眼本體的孔柱部的前端將布料推 壓至第2孔眼模的軸部的傾斜面，接下來，利用孔柱部經 由傾斜面將軸部推向下方，使得軸部朝向下方彈性位移。 在該軸部位移步驟中，實質上進行著孔眼本體的孔柱部的 前端所導致的布料的切斷、貫通。軸部位移步驟後，從第 1孔眼模側利用推壓使得套筒部朝向下方彈性地移動，而 在該套筒部位移步驟中’孔眼本體及孔柱部的鉚接實質地 進行。 在本發明中，欲將孔眼本體及·墊圈安裝於布料之際， -10- 201242734 孔眼本體的孔柱部的前端所導致的布料切斷，在軸部的傾 斜面上’使得軸部被推至孔柱部一面位移一面進行。所 以’孔柱部的前端所導致的布料的切斷成爲容易且確實， 而在布料不會發生難看的縐紋，或是幾乎不會有如孔柱部 壓曲的情形》 【實施方式】 以下’一面參照圖式一面說明本發明的合適的實施形 態、·第1圖是局部切剖表示構成藉由本發明的孔眼安裝裝 置來安裝於布料1的孔眼的孔眼本體（eye丨et)10與墊圈 (washer) 2 0的立體說明圖。第2圖是—起槪略地表示本發 明的一實施形態的孔眼安裝裝置3 〇的主要部分的上方孔 眼模3 1及下方孔眼模4〇，與孔眼本體1 〇、布料1及墊圈 2〇的縱斷面說明圖。例如，布料】是厚度爲〇·5ηιηι以下 的較難切斷的可爲麻等的天然纖維；尼龍（nyl〇n)、聚酯、 人造絲（rayon)、維尼隆（vinyi〇n)等的化學纖維；芳族聚醯 胺纖維（aramid fiber)、特氟隆（Teflon)纖維、高強度聚乙 稀纖維、PBO纖維、導電纖維等的高功能纖維等。孔眼本 體1〇及塾圈20，是將銅合金、鋁合金等所形成的金屬板 經拉深加工等所形成，如下所述地，較佳地被固定於 〇.5mm以下的較薄布料所得者。孔眼本體10，是包括： 圓同狀的孔柱部1丨’及從孔柱部n的基端（在第2圖中 ^於上方側端）朝向半徑方向外側延伸的環狀凸緣部1 2。 以下’上下方向是依據第2圖。孔柱部η是上下端都是 -11 - 201242734 被開放。孔柱部1 1是又從其基端至前端1 1 a，內徑大 一定且厚度逐漸變薄，孔柱部11的前端11a是成爲 利。孔柱部11的外徑，是從基端至前端11a稍微變小 凸緣部1 2是從孔柱部1 1的基端朝向上方成爲凸狀（朝 下方成爲凹狀）的方式一面彎曲一面朝向半徑方向外側 伸，使凸緣部1 2的半徑方向的內側端與外側端1 2a之 間成爲最上方位置。外側端1 2a是位於比該最上方位置 微下方。墊圈20是包括：圓筒部21，及從圓筒部21 下端朝向半徑方向外側延伸的環狀的外周部22。在墊 20形成有以圓筒部21所包圍的穴部21a，而在其穴 21a可插通有孔眼本體10的孔柱部11。墊圈20的圓筒 21的高度（上下方向亦即沿著墊圈20的軸方向的長度） 是孔眼本體10的孔柱部11的來自凸緣部12的最上端 高度的大約1/2至1/3程度。更進一步，圓筒部21的 徑是一定，比孔眼本體1 0的孔柱部1 1的下端部之外直 還要稍大，並與孔柱部1 1的上端部的外徑大約相同。 周部22，是從圓筒部2 1的下端朝向半徑方向外側成爲 向上方的環狀山部22a與凸向下方的環狀谷部22b形成 形地連續。山部22a，是規定朝向下方開放的環狀第1 受部23a，而谷部22b，是規定朝向上方開放的環狀第 承受部23b。在圓筒部21的內周面，隔著每一預定角 間隔設有沿著軸方向的多數溝24。圓筒部21是對應於 24的部分成爲薄厚度，藉此，在孔眼本體1〇及墊圏 被安裝於下述的布料1時（以下也僅稱爲「安裝孔 約 銳 〇 向 延 中 稍 的 圈 部 部 y 的 內 徑 外 凸 波 承 2 度 溝 20 眼 -12- 201242734 時」），構成至少局部性地可破斷至少幾個溝2 4。 孔眼安裝裝置3 0，是具備：保持著孔眼本體 等的金屬製的上方孔眼模（第1孔眼模）3 1，及載置 20的下方孔眼模（第2孔眼模）40，及用以昇降上方 31的機構（未予圖示）。上方孔眼模31，是被圖示 部分與孔眼本體1〇大約相同直徑的圓柱狀，而於 3 2a，具有一致於孔眼本體10的凸緣部12的環 32。孔眼本體10，是藉由將凸緣部12卡合於上方 3 1的凹部3 2，被保持於上方孔眼模3 1。下方孔眼 是具備：大約圓柱狀的軸部41，及包圍軸部41的 筒狀的套筒部45，及從下方支承此些軸部41及套 的底座部49。下方孔眼模40，是與上方孔眼模3 1 地被配置，而上方孔眼模3 1是能夠沿著其同心的 接近於下方孔眼模40的方向移動。軸部41是由上 等的金屬製的軸部本體42，及從下方支承軸部本H 圓筒狀的軸部彈性體43所構成。軸部彈性體43 置於軸部41與底座部49之間。下方孔眼模40是: 軸部彈性體4 3的半徑方向內側，與軸部4 1同心狀 置，且由底座部49突出，並限制軸部本體42朝向 移的圓柱狀的不鏽鋼等的金屬製止擋44。在軸部；； 的上部（與上方孔眼模30對向的一側），是包括： 平的圓形面42a’及高度從圓形面42a的周緣朝向 向外側逐漸地變低的環狀的軸部傾斜面4 2 b，及從 斜面42b的下端再朝向半徑方向外側一面彎曲一面 1 0的鋼 :有墊圈 孔眼模 的下方 其底面 狀凹部 孔眼模 模40， 大約圓 筒部45 同心狀 軸朝著 方的鋼 ! 42的 是被配 具備：於 地被配 下方位 长體42 中央水 半徑方 軸部傾 使高度 -13- 201242734 稍微變高的環狀的軸部彎曲面42c。圓形面42a的直徑， 是比孔眼本體10的孔柱部11的內徑稍小，因此，在安裝 孔眼時’孔柱部1 1的前端1 1 a，是對應於軸部傾斜面 42b(參照第4圖）。更進一步，當將墊圈20載置於軸部本 體42的上部時，如第3圖所示地，使圓筒部21的下端部 及外周部22的半徑方向內側端部達到軸部彎曲面42c上 的軸部傾斜面42b —側。在軸部本體42中，沿著來自軸 部簿曲面42c的圓形面42a的軸方向的高度，是比墊圈 20的回筒部21的高度稍低，所以，當將布料1水平地舖 設於被載置於軸部本體42的墊圈20上時，如第3圖所示 地，布料1是接觸於墊圈20的圓筒部21的上端，惟稍從 軸部本體42的圓形面42a稍微離開。在軸部本體42的底 部，形成有用以承受止擋44的圓柱狀空洞42d。軸部彈 性體43，是可由螺旋彈簧、橡膠、彈性樹脂、彈性發泡 體等所形成。軸部彈性體43的內徑，是與軸部本體42的 空洞42d之直徑相同，而軸部彈性體43的外徑，是比軸 部本體42的外直徑稍小。所以，軸部彈性體43的外周面 與套筒部45(的下述的套筒彈性體48)的內周面之間產生 環狀空隙。該空隙，是在安裝孔眼時，當軸部彈性體43 朝向軸方向被壓縮之際用以容許軸部彈性體43朝向半徑 方向外側彈性變形者（參照第6圖）。在安裝孔眼時，軸部 本體42 —面朝向軸方向壓縮軸部彈性體43 —面朝向下方 位移之際，對於軸部本體42處於靜止狀態的止擋44會徐 徐地進入軸部本體42的空洞42d，如第6圖所示地，藉 14- 201242734 由止擋44的上端踫到空洞42d的上閉端42e，來阻止軸 部本體42朝向下方其以上的移動。又，軸部本體42的空 洞42d與止擋44之卡合是也發揮做爲朝向下方位移的軸 部本體42的導件的作用。空洞42d的深度，亦即順著軸 方向的長度’是利用止擋44使得下降被限制而對於位在 最下方位置的軸部本體42，如第6圖所示地，設定成孔 眼本體10的孔柱部11幾乎不會變形，使其前端lla接觸 於軸部本體42的軸部傾斜面42b。 套筒部45是由上方的鋼等的金屬製的孔眼模套筒 46 ’及由下方支承孔眼模套筒46的套筒彈性體48所構 成。套筒彈性體48是與上述軸部彈性體43不相同體， 被配置於孔眼模套筒46與底座部49之間。構成這樣子之 故’因而軸部彈性體43與套筒彈性體48，是獨立而能移 彈性地位移。套筒彈性體48，是由螺旋彈簧、橡膠、彈 性樹脂、彈性發泡體等所形成，被設定成比軸部彈性體 43還容易變形。更進一步，套筒彈性體48的上方孔眼模 31的移動方向的長度（同心狀方向的長度），是比軸部彈性 體43的相同方向的長度還要長。在孔眼模套筒46的上部 的半徑方向內側半部，設有由上端面46a凹陷的環狀凹部 47。在凹部47是由：平行於軸線的半徑方向外側端面的 凹部外周面47a，及由凹部外側面47a的下端朝向半徑方 向內側水平地延伸的凹部底面47b，及由凹部底面47b的 半徑方向內側端朝向半徑方向內側傾斜成高度變低的凹部 傾斜面47c所規定。凹部47的直徑，是比墊圈20的外周 -15- 201242734 部22的最大直徑稍大，又，直到凹部47的凹部底面47b 爲止的深度，亦即由上端面46a直到凹部底面47b爲止的 軸方向長度，是比墊圈20的外周部22的上下方向寬度稍 大。更進一步，如第2圖所示的下方孔眼模40的初期狀 態（未施加有來自上方孔眼模3 1側的朝向下的力量於軸部 彈性體43及套筒彈性體48的狀態）之下，上下方向（軸方 向）的凹部底面47b的位置，是位於與軸部本體42的軸部 腎曲面42c大約相同位置。所以，當將墊圈20載置於下 方孔眼模40時，墊圈20的外周部22是被收容於凹部 47(參照第3圖）。凹部傾斜面47c，是在下述的安裝孔眼 時，將孔眼本體1 〇的孔柱部1 1，如第7圖所示地，順著 軸部本體42的軸部傾斜面42b及軸部彎曲面42c彎曲 (curl)之際，使得孔柱部1 1的前端1 la在半徑方向由軸部 本體42偏離當踫到孔眼模套筒46的時機，與軸部彎曲面 42c平緩地連續。在孔眼模套筒46的底部的半徑方向內 側部分，設有朝向下方突出的環狀凸部46b，而在套筒彈 性體48上部的半徑方向內側部分，設有嵌入孔眼模套筒 46的凸部46b的環狀凹部48a。在上述的下方孔眼模40 中，墊圈20的圓筒部21及其周緣（穴部21a的周緣）被載 置於軸部41，由其外側有外周部22被載置於套筒部45。 藉此，墊圈20被保持於下方孔眼模40 »又，如第3圖所 示地，墊圈20的圓筒部21的下端（穴部21a的周緣）是接 觸於軸部41，而且外周部22的下端（谷部2 2b)是接觸於 套筒部45»當將墊圈20載置於下方孔眼模40時，圓筒 -16 - 201242734 部21的下端是與軸部41接觸，而外周部22的下端是也 能夠由套筒部45離間。 以下，做爲本發明的孔眼安裝方法的一實施形態，藉 由上述的孔眼安裝裝置30，將孔眼本體10及墊圈20來 安裝於布料1的步驟加以說明。首先，將孔眼本體1 〇保 持於上方孔眼模3 1，並將墊圈20載置於下方孔眼模40 , 且將布料1水平地舖設於墊圈20上之後，下降上方孔眼 模31。第3圖是孔眼本體10的孔柱部11未接觸於布料i 的狀態。在該時機，在下方孔眼模40的軸部41及套筒部 45未施加朝向下方的推壓力量，軸部41及套筒部45是 在初期位置（初期狀態）。更進一步，當下降上方孔眼模3 i 時，如第4圖所示地，孔眼本體10的孔柱部1 1的前端 11a —面朝向下方帶走布料丨一面踫到軸部本體42的軸 部傾斜面42b。孔柱部1 1的前端1 1 a是銳利，惟因布料1 是較難切斷，因此，在該時機，布料1是至少不會完全地 被切斷。然而，較容易切斷的布料時，在該時機會被切 斷。然後，上方孔眼模31再下降，使得孔眼本體1 〇的孔 柱部1 1是把布料1放在中間而將軸部本體42從軸部傾斜 面42b朝向下方推壓，藉此，軸部本體42是一面將軸部 彈性體43朝向軸方向壓縮一面開始朝向下方位移。這時 候’孔柱部1 1的前端1 1 a對於朝向下方位移的軸部傾斜 面42b ~面推壓布料1，一面如第5圖所示地切斷布料1 而貫通。在第5圖等的參照號碼la，是由布料1切開的 圓形的布料部分。又，藉由孔柱部1 1的前端1 1 a的布料 -17- 201242734 1的切斷’是如上所述地將軸部傾斜面4 2 b —面朝下方位 移一面進行者，與軸部傾斜面42b上下方向地靜止的情形 相比較’可知容易且確實地進行。此可能爲，藉由使得軸 部傾斜面42b予以下降’布料1藉由孔柱部π的前端 11a被引拉至下方，而且在布料1中相當於孔柱部n的 前端1 1 a的部位爲隨著軸部傾斜面42 b的下降朝向半徑方 向內側或外側稍微偏離，使得前端1 1 a在軸部傾斜面42b 上用以作用成能移摩擦布料1。如此地，即使較難切離的 布料1也可確實地被切斷之故，因而孔眼本體10的孔柱 部11是將布料1朝向下方帶走需要以上，當完成對於布 料1的孔眼本體10及墊圈20的固定時，就可避免或減低 在布料1發生縐紋的事態，或是孔柱部1 1成爲壓曲的事 態。 藉由貫通孔眼本體10的孔柱部11的布料1之後，上 方孔眼模3 1也繼續下降，藉此，如第6圖所示地，孔柱 部1 1是幾乎不會變形地能夠將軸部本體42藉由止擋44 被限制爲止向下推壓。在該止擋44的上端抵接於軸部本 體42的時機，軸部彈性體43的軸方向壓縮量是成爲最 大。如此地，停止軸部本體42位移至下方之後，上方孔 眼模3 0仍繼續下降，隨著此，孔眼本體1 〇的凸緣部1 2 的半徑方向內側部分會朝向下方推壓墊圏20，然後，孔 眼模套筒46將套筒彈性體48 —面朝向軸方向壓縮一面朝 向下方開始位移。如第7圖所示地，與下降該孔眼模套筒 46之同時，孔眼本體10的孔柱部1 1從軸部傾斜面42b -18- 201242734 順著軸部彎曲面42c朝向半徑方向外側彎曲。然後，所下 降的孔眼模套筒46的凹部傾斜面47c是與軸部本體42的 軸部彎曲面42c成爲平緩地連續的位置（參照第7圖），不 久，孔眼本體1 0的孔柱部1 1，是從半徑方向外側朝向上 方更彎曲至孔眼模套筒4 6的凹部傾斜面4 7 c側。然後， 如第8圖所示地’上方孔眼模3丨，是其底面3 2 a夾住被 切斷的布料直到踫到下方孔眼模40的軸部本體42的圓形 面42a爲止仍下降，而在該期間使孔眼本體1〇及墊圈2〇 朝向軸方向壓壞的方式更被變形，藉由停止下降上方孔眼 模31，完成孔眼本體10及墊圈20被安裝於布料1。第9 圖是表示構成被安裝於布料1的狀態的環狀孔眼的變形後 的孔眼本體10及墊圈20的縱斷面說明圖，第圖是表 示第9圖的局部擴大圖。在完成該安裝的時機，孔眼本體 10被壓成縱斷面大約C字形狀，一面變形墊圈2〇的圓筒 部21及山部2 2 a —面予以包住。這時候，使孔眼本體j 〇 被彎曲成C字形狀的孔柱部11的前端lla進入墊圈2〇的 外周部22的第1承受部23a，而且孔眼本體1〇的凸緣部 12的外側端12a，是將布料1夾進墊圈20的外周部22的 第2承受部23b。墊圈20的圓筒部21，是在彎曲的孔眼 本體1 〇的內部，使其上端被倒成朝向半徑方向外側打 開。這時候，設置於圓筒部21的多數溝24的至少有幾個 至少局部地破損，另一方面，幾個溝24或是其—部分未 破損而被留下。如此地，藉由局部地留下的溝24，在圓 筒部21，會發生一種復原力量，該復原力量是抗拒藉由 19- 201242734 變形的孔眼本體1 0倒向半徑方向外側而欲再站起來的力 量。所以，在圓筒部21的內周面（在第10圖中大約朝向 上方）與孔眼本體10的上半部分之間能夠牢固地夾住布料 1。所以’即使在薄布料也能夠確實地固定孔眼。 第π圖及第12圖是表示墊圈的變形例的俯視圖及縱 斷面說明圖圖。該墊圈50是包括：直徑朝向上方漸次擴 大的匪筒部51，及與上述的墊圏20的外周部22同樣的 外周部52，而在圓筒部51，未設置如墊圈20的圓筒部 22所具有的溝。在上述的孔眼安裝步驟中，代替墊圈20 使用墊圈50’也可將孔眼本體1〇同樣地安裝於布料1。 第1 3圖是表示下方孔眼模的變形例。該下方孔眼模，是 使用與上述的套筒彈性體48相同的彈性體來形成套筒部 60的整體，而於套筒部60，設有與上述的孔眼模套筒46 的凹部47相同的凹部61。更進一步，套筒部60以外是 與上述的下方孔眼模4 0相同之故，因而給予相同的參照 號碼。在上述的孔眼安裝步驟中，將下方孔眼模40代替 成具有套筒部60的下方孔眼模，就能夠將孔眼本體1〇及 墊圈20或50同樣地安裝於布料1。第14圖是表示下方 孔眼模的另一變形例。該下方孔眼模中，止擋44a是從軸 部本體70的底面朝向下方圓柱狀地突出的方式與軸部本 體70 —體地被設置。此點以外，因與上述的下方孔眼模 40同樣，因此給予相同的參照號碼。止擋44a，是進入軸 部彈性體4 3的半徑方向內側，當安裝孔眼時，軸部本體 70朝向下方被推壓之際，藉由止擋44 a的底面碰到底座 -20- 201242734 部49的上面，停止朝向軸部本體7〇下方的移動。 【圖式簡單說明】 第1圖是表示夾住布料而上下地對向的孔眼本體與墊 圈的立體說明圖。 第2圖是一起表示本發明的一實施形態的孔眼安裝裝 置之腰部的上方孔眼模與下方孔眼模與布料、孔眼本體及 墊圈的縱斷面說明圖。 第3圖是表示在安裝孔眼本體及墊圈於布料時，被保. 持於下降中的上方孔眼模的孔眼本體剛接觸於布料之前的 狀態的局部斷面說明圖。 第4圖是表示在安裝孔眼本體及墊圈於布料時，孔眼 本體的孔柱部推下布料的狀態的局部斷面說明圖。 第5圖是表示在安裝孔眼本體及墊圈於布料時，孔眼 本體的孔柱部剛切斷布料之後的狀態的局部斷面說明圖。 第6圖是表示在安裝孔眼本體及墊圈於布料時，下方 孔眼模的軸部本體推下直到最下方位置的狀態的局部斷面 說明圖。 第7圖是表示在安裝孔眼本體及墊圏於布料時，孔眼 模套筒被推下之同時，孔眼本體的孔柱部被彎曲的狀態的 局部斷面說明圖。 第8圖是表示完成安裝孔眼本體及墊圈於布料的狀態 的局部斷面說明圖。 第9圖是表示構成被安裝於布料的環狀孔眼的變形後 -21 -

Description of the Invention [Technical Field] The present invention relates to an eyelet mounting device and an eyelet mounting method. More specifically, it relates to applying an eyelet body from one side of a cloth, and attaching the pad from the cloth. The other side is applicable to an eyelet mounting device and an eyelet mounting method in which the eyelet body and the gasket are used as the eyelets to be attached to the cloth. [Prior Art] The perforations are used in a circular hole for forming ventilation, shoelaces, and the like on the cloth. Generally, the perforation is a part in which the eyelet main body (the part of the eyelet) is penetrated from the upper side of the fabric arranged horizontally to the lower side, and the eyelet body is attached to the lower side of the fabric by a washer. The mats are riveted together to be mounted on the fabric. It is intended to install such holes in the fabric. A perforated mounting device is used. Generally, the eyelet mounting device includes a lower eyelet mold that holds the eyelet body, a lower eyelet die that is provided with a gasket, and a mechanism for lifting the upper eyelet die. Further, the above-mentioned eyelet is attached by lowering the upper eyelet mold toward the lower eyelet mold. An example of a conventional eyelet mounting device is disclosed in Japanese Laid-Open Patent Publication No. Hei-94801. In the eyelet mounting device, the cloth is cut at the tip end of the hole column portion of the eyelet body held by the upper eyelet mold, and then the hole column portion is bent from the radially outer side toward the upper side in the annular concave portion of the lower eyelet die. . However, for example, in the above-mentioned hole-mounting device of the Japanese Patent No. 201242734, the front end of the hole portion of the eyelet body is excessively pulled away toward the lower side, and when the installation of the eyelet is completed, for example, in the above-mentioned hole-mounting device of 201242734, An unsightly crepe pattern is formed around the perforations of the fabric, or the perforated column portion cannot penetrate the fabric and also has buckling. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide an eyelet mounting device which is provided when an eyelet is attached to a cloth. It is easy and reliable to cut the cloth by the front end of the hole column portion of the hole body.

The shaft portion is abuttable against a peripheral edge of the hole portion of the gasket. In the present invention, the peripheral edge of the pocket portion of the gasket can abut against the shaft portion of the second orifice mold, and the outer portion in the radial direction of the gasket portion is abutted against the concave portion of the sleeve portion of the second orifice mold. Therefore, the washer is held in the shaft portion of the second hole eye mold and the sleeve portion is comprehensive. Therefore, compared with the case where the collar is supported by the shaft portion, the perforation mounting device described in Japanese Laid-Open Patent Publication No. Hei No. 1-94801 is cut by the cloth at the hole column portion of the eyelet body or after the hole column portion. When the caulking is deformed, the shaft portion and the sleeve portion are relatively displaced, respectively, and the operation of applying the second hole eye mold can be achieved. Therefore, the installation of the holes can be surely performed. In one embodiment of the present invention, the shaft portion is relatively independent from the sleeve portion when the eyelet body and the gasket are attached to the fabric by being relatively pressed from the first orifice mold side. The ground displacement is in a direction in which the first hole eye mold relatively presses the second hole eye mold. At this time, it is possible to perform the most suitable operation of the shaft portion and the sleeve portion when the cloth is cut by the hole portion of the eyelet main body or the subsequent swaging deformation of the hole column portion. Further, according to another aspect of the invention, there is provided a method for mounting an eyelet, wherein a cylindrical hole portion of a hole main body held by a first orifice die is passed through from one side of the cloth to the other side, and then the cloth is used. The other side of the face 201242734 is a hole-mounting method for attaching the gasket of the second hole eye mold to the second eye mold, and the eyelet body and the gasket are used as the eyelets for attaching to the cloth. The second hole eye mold includes a cylindrical shaft. And a cylindrical sleeve portion surrounding the shaft portion, the shaft portion having an annular inclined surface for receiving the tip end of the hole column portion and bending the hole column portion outward in the radial direction, When the 2-hole eye mold is relatively pressed by the first hole eye mold, the shaft portion displacement step and the sleeve displacement step are performed, wherein the shaft portion is elastically displaced to the first hole eye mold a direction in which the second hole eye mold is relatively pressed, and the sleeve displacement step is to elastically displace the sleeve portion in the direction after the shaft portion displacement step, and to make the eyelet in the shaft portion displacement step The distal end portion of the peg body side of the inclined surface of the fabric relative to the shaft portion is pressed, and cut off the side of the cloth. In the present invention, after the eyelet body is held by the upper first eyelet mold, and the gasket is placed on the lower second eyelet mold, and the cloth is horizontally disposed between the eyelet body and the gasket, the first eyelet mold is placed. The eye mold is lowered toward the second hole. Therefore, first, the tip end of the hole column portion of the hole main body presses the cloth to the inclined surface of the shaft portion of the second eye mold, and then the hole portion pushes the shaft portion downward via the inclined surface, so that the shaft portion faces downward. The elastic displacement below. In the shaft portion displacement step, the cutting and penetration of the cloth due to the tip end of the hole column portion of the eyelet body are substantially performed. After the shaft portion displacement step, the sleeve portion is elastically moved downward by the pressing from the first orifice mold side, and the caulking of the orifice main body and the hole column portion is substantially performed in the sleeve portion displacement step.

The displacement is performed while the column portion is displaced. Therefore, the cutting of the fabric caused by the front end of the hole column portion is easy and reliable, and the unpleasant crepe pattern does not occur in the cloth, or there is almost no case where the hole portion is bucked. [Embodiment] A preferred embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a partial cross-sectional view showing an eyelet body 10 and a gasket (which are attached to the eyelet of the fabric 1 by the eyelet mounting device of the present invention). Stereo illustration of the washer) 2 0. Fig. 2 is a view schematically showing the upper eyelet die 3 1 and the lower eyelet die 4 主要 of the main portion of the eyelet mounting device 3 according to the embodiment of the present invention, and the eyelet body 1 布料, the cloth 1 and the gasket 2 〇 Longitudinal section illustration. For example, cloth is a natural fiber which is difficult to cut and has a thickness of less than 〇·5ηιηι, such as hemp; nylon (nyl〇n), polyester, rayon, vinyi〇n, etc. Chemical fiber; high-performance fiber such as aramid fiber, Teflon fiber, high-strength polyethylene fiber, PBO fiber, conductive fiber, and the like. The eyelet body 1〇 and the ring 20 are formed by drawing a metal plate formed of a copper alloy, an aluminum alloy or the like, and are preferably fixed to a thin cloth of 〇5 mm or less as described below. . The eyelet body 10 includes an annular column portion 1'' and a ring-shaped flange portion 1 extending outward from the base end (the upper side end in the second figure) of the hole column portion n toward the outside in the radial direction. 2. The following 'up and down direction is based on Figure 2. The column η is open at both upper and lower ends -11 - 201242734. The hole column portion 1 1 has a larger inner diameter and a gradually smaller thickness from the base end to the front end 1 1 a, and the front end portion 11a of the hole column portion 11 is advantageous. The outer diameter of the hole-portion portion 11 is slightly smaller from the base end to the front end 11a. The flange portion 1 2 is curved from the base end of the hole-portion portion 1 1 toward the upper side (a concave shape toward the lower side). The outer side is extended in the radial direction so that the inner side end of the flange portion 12 in the radial direction and the outer end 12b become the uppermost position. The outer end 1 2a is located slightly below the uppermost position. The gasket 20 includes a cylindrical portion 21 and an annular outer peripheral portion 22 that extends radially outward from the lower end of the cylindrical portion 21. The hole portion 21a surrounded by the cylindrical portion 21 is formed in the pad 20, and the hole column portion 11 of the eyelet body 10 is inserted into the hole 21a. The height of the cylinder 21 of the gasket 20 (the vertical direction, that is, the length along the axial direction of the gasket 20) is about 1/2 to 1 of the height of the uppermost end of the boss portion 11 of the eyelet body 10 from the flange portion 12. 3 degrees. Further, the diameter of the cylindrical portion 21 is constant, which is slightly larger than the lower end portion of the hole column portion 1 1 of the eyelet body 10, and is approximately the same as the outer diameter of the upper end portion of the hole column portion 11. The circumferential portion 22 is formed continuously from the lower end of the cylindrical portion 21 toward the outer side in the radial direction, and the annular portion 22a that is upward and the annular portion 22b that is convex downward. The mountain portion 22a is an annular first receiving portion 23a that is opened downward, and the valley portion 22b is an annular first receiving portion 23b that is opened upward. On the inner circumferential surface of the cylindrical portion 21, a plurality of grooves 24 along the axial direction are provided at intervals of each predetermined angle. The portion of the cylindrical portion 21 corresponding to 24 is formed to have a small thickness. Therefore, when the eyelet body 1b and the pad are attached to the cloth 1 described below (hereinafter, simply referred to as "the mounting hole is slightly sharper and slightly extended" The inner diameter of the portion y is convex and the second wave is 20 degrees -12 - 201242734"), and at least a plurality of grooves 24 can be broken at least partially. The eyelet attachment device 30 includes a metal upper eye mold (first aperture mold) 3 1 that holds an eyelet body or the like, and a lower aperture mold (second aperture mold) 40 on which the 20 is placed, and is used for lifting The mechanism above 31 (not shown). The upper eye mold 31 is a cylindrical shape having a portion of the same diameter as that of the eyelet body 1b, and has a ring 32 which is identical to the flange portion 12 of the eyelet body 10 at 32a. The eyelet body 10 is held by the upper eyelet mold 31 by engaging the flange portion 12 with the concave portion 3 2 of the upper portion 31. The lower eyelet includes a cylindrical shaft portion 41, a cylindrical sleeve portion 45 that surrounds the shaft portion 41, and a base portion 49 that supports the shaft portions 41 and the sleeve from below. The lower eye mold 40 is disposed with the upper eye mold 31, and the upper eye mold 31 is movable in a direction close to the lower eye mold 40 concentrically therewith. The shaft portion 41 is composed of an upper metal shaft main body 42 and a shaft portion elastic body 43 that supports the H-cylindrical portion from the lower side. The shaft portion elastic body 43 is placed between the shaft portion 41 and the base portion 49. The lower eyelet mold 40 is made of metal in the radial direction of the shaft portion elastic body 43 and is concentric with the shaft portion 41 and protrudes from the base portion 49 to restrict the cylindrical portion body 42 from moving toward the cylindrical stainless steel. Stop 44. The upper portion of the shaft portion; (the side opposite to the upper eye mold 30) includes a flat circular surface 42a' and an annular shape whose height gradually decreases from the periphery of the circular surface 42a toward the outer side. The shaft inclined surface 4 2 b and the steel which is bent from the lower end of the inclined surface 42b toward the outer side in the radial direction by one side 10: the bottom surface-shaped concave portion eye mold 40 below the washer hole mold, approximately the cylindrical portion 45 concentric shaft The steel member 42 of the square is provided with a ring-shaped curved portion 42c that is slightly increased in height from the height of the center-water radius of the square body portion 42 to 201242734. The diameter of the circular surface 42a is slightly smaller than the inner diameter of the hole column portion 11 of the eyelet body 10. Therefore, when the eyelet is mounted, the front end 1 1 a of the hole column portion 1 1 corresponds to the shaft portion inclined surface 42b ( Refer to Figure 4). Further, when the gasket 20 is placed on the upper portion of the shaft portion main body 42, as shown in Fig. 3, the radially inner end portion of the lower end portion and the outer peripheral portion 22 of the cylindrical portion 21 reaches the shaft portion curved surface 42c. The upper shaft inclined surface 42b is on the side. In the shaft portion body 42, the height in the axial direction of the circular surface 42a from the shaft portion curved surface 42c is slightly lower than the height of the back tube portion 21 of the gasket 20, so when the cloth 1 is horizontally laid When placed on the washer 20 of the shaft portion body 42, as shown in Fig. 3, the cloth 1 is in contact with the upper end of the cylindrical portion 21 of the washer 20, but slightly slightly from the circular surface 42a of the shaft portion body 42. go away. At the bottom of the shaft portion body 42, a cylindrical cavity 42d for receiving the stopper 44 is formed. The shaft portion elastic body 43 can be formed of a coil spring, rubber, an elastic resin, an elastic foam or the like. The inner diameter of the shaft portion elastic body 43 is the same as the diameter of the cavity 42d of the shaft portion body 42, and the outer diameter of the shaft portion elastic body 43 is slightly smaller than the outer diameter of the shaft portion body 42. Therefore, an annular gap is formed between the outer peripheral surface of the shaft portion elastic body 43 and the inner peripheral surface of the sleeve portion 45 (the following sleeve elastic body 48). When the hole portion is compressed, the hole portion elastic member 43 is elastically deformed toward the outer side in the radial direction when the shaft portion elastic body 43 is compressed in the axial direction (see Fig. 6). When the eyelet body 42 is mounted on the hole, the surface of the shaft body 42 is displaced downward toward the axial direction, and the stop 44 of the shaft body 42 in a stationary state gradually enters the cavity of the shaft body 42. 42d, as shown in Fig. 6, by the upper end of the stopper 44 to the upper closed end 42e of the cavity 42d by 14-201242734, the movement of the shaft portion body 42 downward is prevented. Further, the engagement of the cavity 42d of the shaft portion body 42 with the stopper 44 also functions as a guide for the shaft body 42 that is displaced downward. The depth of the cavity 42d, that is, the length along the axial direction is the shaft portion body 42 that is restricted by the stopper 44 and is positioned at the lowest position, as shown in Fig. 6, is set as the eyelet body 10 The hole column portion 11 is hardly deformed, and the tip end 11a is brought into contact with the shaft portion inclined surface 42b of the shaft portion body 42. The sleeve portion 45 is formed of a metal eyelet sleeve 46' such as steel above and a sleeve elastic body 48 that supports the eyelet sleeve 46 from below. The sleeve elastic body 48 is different from the shaft elastic body 43 and is disposed between the eye mold sleeve 46 and the base portion 49. Thus, the shaft elastic body 43 and the sleeve elastic body 48 are independently and elastically displaceable. The sleeve elastic body 48 is formed of a coil spring, rubber, elastic resin, elastic foam or the like, and is set to be easily deformed more than the shaft portion elastic body 43. Further, the length (the length in the concentric direction) of the upper end of the eyelet die 31 in the moving direction of the sleeve elastic body 48 is longer than the length of the shaft elastic body 43 in the same direction. An annular recessed portion 47 recessed by the upper end surface 46a is provided in the radially inner half of the upper portion of the eyelet die sleeve 46. The recessed portion 47 is a recessed portion outer peripheral surface 47a that is parallel to the radially outer end surface of the axis, and a recessed bottom surface 47b that extends horizontally from the lower end of the recessed outer surface 47a toward the radially inner side, and a radially inner end of the recessed bottom surface 47b. The concave inclined surface 47c is inclined so as to be inclined toward the inner side in the radial direction. The diameter of the recess 47 is slightly larger than the maximum diameter of the outer circumference -15-201242734 portion 22 of the gasket 20, and the depth up to the concave bottom surface 47b of the recess 47, that is, the axial direction from the upper end surface 46a to the concave bottom surface 47b. The length is slightly larger than the width of the outer peripheral portion 22 of the gasket 20 in the vertical direction. Further, in the initial state of the lower perforating mold 40 shown in Fig. 2 (the state in which the downward force from the upper perforating die 31 side is not applied to the shaft elastic body 43 and the sleeve elastic body 48) is performed. The position of the concave bottom surface 47b in the vertical direction (axial direction) is located at approximately the same position as the shaft portion kidney curved surface 42c of the shaft portion body 42. Therefore, when the gasket 20 is placed on the lower orifice mold 40, the outer peripheral portion 22 of the gasket 20 is housed in the recess 47 (see Fig. 3). The concave inclined surface 47c is a hole portion 1b of the hole main body 1 as shown in Fig. 7 when the hole is attached as follows, and the inclined portion 42b and the curved portion of the shaft portion of the shaft portion 42 are curved as shown in Fig. 7 . When the 42c is curled, the front end 1 la of the hole column portion 1 1 is displaced from the shaft portion body 42 in the radial direction by the timing of the hole portion to the hole mold sleeve 46, and is smoothly continuous with the shaft portion curved surface 42c. An annular convex portion 46b that protrudes downward is provided in a radially inner portion of the bottom portion of the eyelet die sleeve 46, and a convex portion that is fitted into the hole die sleeve 46 is provided in a radially inner portion of the upper portion of the sleeve elastic body 48. The annular recess 48a of the portion 46b. In the lower hole mold 40 described above, the cylindrical portion 21 of the gasket 20 and its peripheral edge (the periphery of the pocket portion 21a) are placed on the shaft portion 41, and the outer peripheral portion 22 is placed on the sleeve portion 45. Thereby, the washer 20 is held by the lower eyelet mold 40. Further, as shown in Fig. 3, the lower end of the cylindrical portion 21 of the washer 20 (the peripheral edge of the hole portion 21a) is in contact with the shaft portion 41, and the outer peripheral portion 22 The lower end (the valley portion 22b) is in contact with the sleeve portion 45». When the gasket 20 is placed on the lower hole mold 40, the lower end of the cylinder-16 - 201242734 portion 21 is in contact with the shaft portion 41, and the outer peripheral portion 22 The lower end can also be separated from the sleeve portion 45. Hereinafter, as an embodiment of the eyelet attachment method of the present invention, the step of attaching the eyelet body 10 and the gasket 20 to the cloth 1 by the above-described eyelet attachment device 30 will be described. First, the eyelet body 1 is held in the upper eye mold 3 1, and the gasket 20 is placed on the lower eye mold 40, and after the cloth 1 is horizontally laid on the gasket 20, the upper eye mold 31 is lowered. Fig. 3 is a view showing a state in which the hole column portion 11 of the hole main body 10 is not in contact with the cloth i. At this timing, the amount of pressing force directed downward is not applied to the shaft portion 41 and the sleeve portion 45 of the lower eye mold 40, and the shaft portion 41 and the sleeve portion 45 are at the initial positions (initial state). Further, when the upper eye mold 3 i is lowered, as shown in Fig. 4, the front end 11a of the hole portion 1 of the eyelet body 10 faces away from the fabric, and the shaft portion of the shaft portion 42 is pulled to the shaft portion of the shaft portion 42. Inclined surface 42b. The front end 1 1 a of the hole column portion 1 1 is sharp, but since the cloth 1 is difficult to cut, the cloth 1 is at least not completely cut at this timing. However, when it is easier to cut the cloth, the opportunity is cut off at that time. Then, the upper eye mold 31 is lowered again, so that the hole portion 1 1 of the eyelet body 1 is placed with the cloth 1 interposed therebetween, and the shaft portion body 42 is pressed downward from the shaft portion inclined surface 42b, whereby the shaft portion body 42 is a downward displacement of the shaft elastic body 43 while being compressed in the axial direction. At this time, the tip end 1 1 a of the hole column portion 1 1 presses the cloth 1 against the inclined portion 42b of the shaft portion that is displaced downward, and cuts the cloth 1 as shown in Fig. 5 to penetrate. The reference number la in Fig. 5 and the like is a circular cloth portion cut by the cloth 1. In addition, the cutting of the cloth -17-201242734 1 by the tip end 1 1 a of the hole column portion 1 1 is performed while the shaft portion inclined surface 4 2 b is displaced downward as described above, and the shaft portion When the inclined surface 42b is stationary in the vertical direction, it can be seen that it is easy and sure to perform. This may be caused by lowering the inclined portion 42b of the shaft portion. The cloth 1 is drawn downward by the front end 11a of the hole portion π, and corresponds to the portion of the front end 1 1 a of the hole portion n in the cloth 1. In order to slightly deviate toward the inner side or the outer side in the radial direction as the axial inclined surface 42 b is lowered, the front end 1 1 a acts on the shaft inclined surface 42b to act as the movable rubbing fabric 1. In this way, even if the cloth 1 which is difficult to cut off can be surely cut, the hole column portion 11 of the eyelet body 10 needs to be taken up and down the cloth 1 when the cloth 1 is completed. When the gasket 20 is fixed, it is possible to avoid or reduce the occurrence of creases in the cloth 1, or the state in which the column portion 1 1 is buckling. After passing through the cloth 1 of the hole column portion 11 of the eyelet body 10, the upper eye mold 3 1 also continues to descend, whereby as shown in Fig. 6, the hole column portion 1 can be axially deformed. The body portion 42 is pushed downward by the stop 44 being restrained. When the upper end of the stopper 44 abuts against the shaft portion body 42, the amount of compression of the shaft portion elastic body 43 in the axial direction is maximized. In this manner, after the stop shaft portion body 42 is displaced downward, the upper eyelet mold 30 continues to descend. Accordingly, the radially inner portion of the flange portion 1 2 of the eyelet body 1 推 pushes the pad 20 downward. Then, the eyelet die sleeve 46 is displaced toward the lower side in the direction in which the sleeve elastic body 48 is compressed in the axial direction. As shown in Fig. 7, while the hole die sleeve 46 is lowered, the hole column portion 1 of the eyelet body 10 is bent from the shaft portion inclined surface 42b-18-201242734 toward the radial direction outward along the shaft portion curved surface 42c. . Then, the recessed inclined surface 47c of the lowered eyelet sleeve 46 is a position that is gentle with the shaft curved surface 42c of the shaft main body 42 (see FIG. 7), and soon, the hole portion of the eyelet body 10 1 1 is a side which is bent more from the outer side in the radial direction toward the upper side to the inclined surface of the concave portion of the eye mold sleeve 46. Then, as shown in Fig. 8, the upper eyelet mold 3 is such that the bottom surface 3 2 a sandwiches the cut fabric until it reaches the circular surface 42a of the shaft portion body 42 of the lower eye mold 40. In the meantime, the hole main body 1〇 and the washer 2〇 are deformed in the axial direction, and the eyelet body 10 and the gasket 20 are attached to the cloth 1 by stopping the lowering of the upper eye mold 31. Fig. 9 is a longitudinal cross-sectional view showing the perforated body 10 and the gasket 20 after the deformation of the annular perforation in the state in which the fabric 1 is attached, and Fig. 9 is a partially enlarged view showing the ninth drawing. At the timing of completion of the mounting, the eyelet body 10 is pressed into a C-shaped longitudinal section, and the cylindrical portion 21 and the mountain portion 2 2 a of the deformed gasket 2 are covered. At this time, the end portion 11a of the hole column portion 11 in which the hole main body j is bent into the C-shape enters the first receiving portion 23a of the outer peripheral portion 22 of the gasket 2A, and the outer end portion of the flange portion 12 of the eyelet body 1〇 12a is a second receiving portion 23b that sandwiches the cloth 1 into the outer peripheral portion 22 of the gasket 20. The cylindrical portion 21 of the gasket 20 is inside the curved eyelet body 1 ,, and its upper end is inverted so as to open outward in the radial direction. At this time, at least some of the plurality of grooves 24 provided in the cylindrical portion 21 are at least partially broken, and on the other hand, several grooves 24 or portions thereof are not damaged and are left. In this way, by the groove 24 partially left, a restoring force is generated in the cylindrical portion 21, and the restoring force resists the reverse direction of the eyelet body 10 deformed by 19-201242734 to re-stand. The power to get up. Therefore, the cloth 1 can be firmly held between the inner peripheral surface of the cylindrical portion 21 (about upward in the tenth diagram) and the upper half of the eyelet body 10. Therefore, the hole can be securely fixed even in a thin cloth. Fig. π and Fig. 12 are a plan view and a longitudinal cross-sectional explanatory view showing a modification of the gasket. The gasket 50 includes a cylindrical portion 51 whose diameter gradually increases toward the upper side, and an outer peripheral portion 52 similar to the outer peripheral portion 22 of the above-described pad 20, and a cylindrical portion such as the gasket 20 is not provided in the cylindrical portion 51. 22 have a ditch. In the above-described hole mounting step, the eyelet body 1 can be similarly attached to the cloth 1 by using the gasket 50' instead of the gasket 20. Fig. 13 is a modification showing the lower eyelet mold. The lower eyelet mold is formed by using the same elastic body as the above-described sleeve elastic body 48 to form the entire sleeve portion 60, and the sleeve portion 60 is provided with the same recessed portion 47 as the above-mentioned eyelet die sleeve 46. Concave portion 61. Further, the sleeve portion 60 is the same as the above-described lower hole mold 40, and thus the same reference numeral is given. In the above-described hole mounting step, the lower hole mold 40 is replaced with the lower hole mold having the sleeve portion 60, and the eyelet body 1 and the gasket 20 or 50 can be attached to the cloth 1 in the same manner. Fig. 14 is a view showing another modification of the lower eyelet mold. In the lower eyelet mold, the stopper 44a is integrally provided with the shaft portion body 70 so as to protrude cylindrically downward from the bottom surface of the shaft body 70. Other than this point, since it is the same as the above-described lower eyelet die 40, the same reference numerals are given. The stopper 44a is inserted into the radially inner side of the shaft portion elastic body 43. When the shaft portion body 70 is pressed downward when the eyelet is attached, the bottom surface of the stopper 44a hits the base -20-201242734 portion. Above the 49, the movement toward the lower side of the shaft body 7〇 is stopped.
