【発明の属する技術分野】
本発明は、カッタナイフのスライダに係り、主としてマガジン式カッタナイフに用いられるスライダの改良に関する。
【０００２】
【従来の技術】
従来、この種のカッタナイフのスライダとしては、例えば実公昭５３−４５３５８号や実公昭６２−４１７２５号に記載されたものが知られている。
これらは、基本的には、刃体と連結する為の連結突起を備えた金属製のベースと、これの表側に位置されたカバーと、ベースとカバーで囲まれる内部に収容されて一部が外突してホルダの掛止凹部に弾合されるバネと、ベースとカバーとの間に設けられてこれらを合体させる抜止手段とから構成されている。
【０００３】
【発明が解決しようとする課題】
ところが、この様なものは、ベースとカバーとの間に抜止手段を設けていると共に、ベースが金属製であったので、落下等に依り衝撃が加わった時には、抜止手段のベース側が変形すると共に、そのまま使用していると、ベースに対してカバーがガタついて変形が繰り返され、遂には変形箇所が折れて両者が分解し易かった。又、分解されると、折損箇所があるので、再組立ができない難点があった。
本発明は、叙上の問題点に鑑み、これを解消する為に創案されたもので、その目的とする処は、落下等に依り衝撃が加わっても構成部品が分解し難い様にすると共に、分解しても再組立が行なえる様にしたカッタナイフのスライダを提供するにある。
【０００４】
【課題を解決するための手段】
請求項１の発明は、刃体７０を連結するための連結突起７を設けた長方形状の金属ベース２と，当該金属ベース２の一側面に間隔を置いて対向状にアウトサート形成された前方部の***部１６及び後方部の***部１６と、前記両***部１６、１６の中間にアウトサート形成されて前後両***部１６、１６との間に傾斜状の収容溝２０、２０を形成すると共に中央部に抜止部３１を有する収容孔１８を備えた中央の***部１６とを備える合成樹脂製のボディ３と，底辺２８の両端から斜上方へ向けて前傾弾片２９と後傾弾片３０とが延設して形成され、前記収容溝２０、２０内へ前傾弾片２９と後傾弾片３０を挿入せしめて金属ベース２に装着されると共に、前記両傾弾片２９、３０の先端をホルダ６０の離間する二つの掛止凹部６６、６６に掛止させた帯板状のバネ５と，長手方向の上端及び下端に上壁２１及び下壁２２を有する長方形状の表壁２３と、当該表壁２３の一側面から前方へ突設され、前記中央の***部１６の収容孔１８内へ挿着されてこれに掛止される抜止部３２を備えた抜止手段６と、表壁２３の前記中央の***部１６の両端部に対応する位置の上壁２１より下方へ向けて夫々突設され、表壁２３の前動により前記前傾弾片２９と掛止凹部６６との係合を解除させ、また表壁２３の後動により前記後傾弾片３０と掛止凹部６６との係合を解除させる二つの解除突起２７、２７とが一体的形成され、前記金属ベース２及び合成樹脂製ボディ３に対して前後動可能に嵌着したカバー４と，から構成したことを発明の基本構成とするものである。
【０００５】
金属製のベースに合成樹脂製のボディがアウトサート成形されているので、落下等に依り衝撃が加わってもこれらが分解される事がない。
ベースとボディとカバーで囲まれる内部には、バネが収容されて抜止手段に依りボディとカバーとが合体される。つまり、ベースとカバーとは、ボディを介して取付けられているので、落下等に依り衝撃が加わっても、合成樹脂製のボディが衝撃を吸収し、抜止手段が折損される事がないと共に、ボディとカバーが分解され難くなる。
もし、分解されても、抜止手段に依りボディとカバーを再び合体する事が可能となる。
【０００６】
【発明の実施の形態】
以下、本発明の実施の形態を、図面に基づいて説明する。
図１は、本発明のスライダを示す分解斜視図。図２は、ベースとボディを示す背面斜視図。図３は、組立状態を示す拡大縦断側面図。図４は、図２の正面図。図５は、図４のＡ−Ａ横断平面図。図６は、カッタナイフにした状態を示す要部正面図。図７は、前進作動状態を示す図６と同様図である。
【０００７】
スライダ１は、ベース２、ボディ３、カバー４、バネ５、抜止手段６とからその主要部が構成されて居り、マガジン式等のカッタナイフ５０に適用されるオートロック式にしてある。
【０００８】
カッタナイフ５０は、ホルダ６０と刃体７０とスライダ１等から構成されている。
ホルダ６０は、断面略Ｃ型を呈し、上壁６１、下壁６２、上部表壁６３、下部表壁６４、裏壁６５、上部表壁６３の下部に形成された略半円状を呈する多数の掛止凹部６６とから成り、金属板（ステンレス鋼板）をプレス加工する事に依り作製されている。
刃体７０は、略平行四辺形を呈した折刃式にされ、後側に形成された連結孔７１と、下縁に形成された刃７２と、所定間隔毎に形成された折線７３とを備えて居り、金属板（刃物鋼板）に依り作製されている。
【０００９】
ベース２は、刃体７０と連結する為の連結突起７を備えた金属製のもので、この例では、前部に設けられて表側に反った略半円状の反り片８と、これの後方近傍に設けられて裏側に突出された連結突起７と、中程に穿設された略Ｔ型の窓孔９と、これの前後両側近傍に穿設された三つづつの円状の貫孔１０と、これらの前後両側近傍に穿設された前側に八つ後側に五つの円状の貫孔１１と、中程の上下に削設された半円状の切欠１２と、後部寄りの裏側に膨出された摺動突起１３と、後部に設けられて表側に反った反り部１４とを備え、略平板状を呈してステンレス鋼板をプレス加工する事に依り作製されている。窓孔９と貫孔１０，１１は、アウトサート成形する為の連通部を為している。
【００１０】
ボディ３は、ベース２にアウトサート成形された合成樹脂製のもので、この例では、ベース２の裏側に位置する略平行四辺形状の平板部１５と、ベース２の表側に位置して三つのものから成る***部１６と、ベース２の連通部（窓孔９、貫孔１０，１１）に位置して平板部１５と***部１６を連結する連結部１７と、中央の***部１６に表側から形成された収容孔１８と、中央の***部１６と平板部１５に形成されて収容孔１８から裏側に貫通する抜孔１９と、三つの***部１６の間に形成されて略Ｖ型を為す収容溝２０とを備え、合成樹脂に依り作製されてベース２の外側に一体的にアウトサート成形されている。平板部１５と中央の***部１６とは、窓孔９の内周に位置する連結部１７とこれの前後にある各三つの貫孔１０に位置する連結部１７に依り連結されている。平板部１５と前側の***部１６とは、八つの貫孔１１に位置する連結部１７に依り連結されている。平板部１５と後側の***部１６とは、後側の五つの貫孔１１に位置する連結部１７に依り連結されている。
【００１１】
カバー４は、ベース２の表側に位置されたもので、この例では、上壁２１と、下壁２２と、表壁２３と、これの表面に形成された辷止凹凸２４と、表壁２３に貫通して穿設された多数の透孔（図示せず）と、上壁２１と下壁２２間の前側に形成されたクランク型の連結壁２５と、上壁２１の後部に形成された後突起２６と、上壁２１の中程に形成された前後の解除突起２７とを備え、断面略Ｃ型を呈して合成樹脂に依り作製されている。解除突起２７は、ボディ３の中央の***部１６との間でストッパ手段を為し、ボディ３に対するカバー４の前後動が規制される。
【００１２】
バネ５は、ベース２とボディ３とカバー４で囲まれる内部に収容されて一部が外突してホルダ６０の掛止凹部６６に弾合されるもので、この例では、底片２８と、これの前端から前上斜め方向に延設されてホルダ６０の離間する二つの掛止凹部６６のうちの一方に掛合して前動を阻止する前傾弾片２９と、底片２８の後端から後上斜め方向に延設されてホルダ６０の離間する二つの掛止凹部６６のうちの他方に掛合して後動を阻止する後傾弾片３０とを備え、略Ｖ型を呈してステンレス鋼板をプレス加工する事に依り作製されている。前傾弾片２９の遊端部は、前側に直角に折曲されていると共に、後傾弾片３０の遊端部は、後側に直角に折曲されている。
【００１３】
抜止手段６は、ボディ３とカバー４との間に設けられてこれらを合体させるもので、この例では、ボディ３の中央の***部１６に設けられて収容孔１８内に位置される上下の抜止部３１と、カバー４の表壁２３の裏側中程に設けられて抜止部３１に前後動可能に掛合される楔状の抜止部３２とから成り、ボディ３に対してカバー４が中立位置とこれを挾む前動位置及び後動位置を夫々とり得る様にしてある。
【００１４】
この様なスライダ１は、次の様にして組み立てられる。ボディ３は、アウトサート成形に依りベース２に一体的に取付けられている。この様なものに於けるボディ３の収容溝２０にバネ５を挿入して三つの***部１６に依りこれを収容保持する。ボディ３の表側にカバー４を配置した後、カバー４の抜止部３２をボディ３の抜止部３１の表側に当てがい、カバー４をボディ３側に強圧すると、上下の抜止部３１間が拡がり、抜止部３１と抜止部３２が離脱不能に掛合される。つまり、地獄嵌め又は嵌め殺しされる。そうすると、ボディ３の***部１６の表側過半がカバー４の上壁２１と下壁２２と表壁２３で囲まれる収容腔内に収容されると共に、前後の解除突起２７が前傾弾片２９と後傾弾片３０の遊端部間に位置され、ボディ３に対してカバー４が前後動可能に組立られる。この時、ボディ３の収容溝２０は、カバー４に依り閉塞されるので、バネ５が外脱する事がなく、バネ５は、ベース２とボディ３とカバー４で囲まれた内部に収容されて前傾弾片２９と後傾弾片３０の各遊端のみがボディ３の***部１６の上側に外突されている。
組立られたスライダ１は、ベース２とボディ３とカバー４とに依り***部１６の上下に凹溝が形成される事になる。而して、スライダ１は、上下の凹溝にホルダ６０の上部表壁６３と下部表壁６４が内部に臨むべくホルダ６０に前後動可能に嵌挿され、ベース２の連結突起７が刃体７０の連結孔７１に嵌挿されて連結される。ホルダ６０には、複数の刃体７０を収容したマガジン（図示せず）が装填されて居り、最も表側の刃体７０から順にスライダ１に連結される様になっている。
【００１５】
次に、この様な構成に基づいて作用を述解する。
図６は、スライダ１がホルダ６０に対して停止し、所謂オートロック状態にある場合を示している。
この時、カバー４は、中立位置にあり、バネ５の前傾弾片２９と後傾弾片３０の各遊端部は、ホルダ６０の多数の掛止凹部６６のうちの離間する二つの掛止凹部６６に掛合している。この為、ボディ３の***部１６の下面は、ホルダ６０の下部表壁６４の上縁に当合される。
そして、前後の解除突起２７は、バネ５の前傾弾片２９と後傾弾片３０の各遊端部間にその弾力に依り位置して、両弾片２９，３０と掛止凹部６６との掛合を許容している。
この様な状態で、刃体７０を介してスライダ１が前進しようすると、前傾弾片２９と掛止凹部６６とが掛合しているので、前傾弾片２９が所謂突支え棒として機能し、これが阻止される。
逆に、刃体７０を介してスライダ１が後進しようとすると、後傾弾片３０と掛止凹部６６とが掛合しているので、後傾弾片３０が所謂突支え棒として機能し、これが阻止される。
従って、刃体７０並びにスライダ１は、外力が作用しても、前後いずれの方向にも移動せず、ホルダ６０に対して所謂オートロックされる。
【００１６】
スライダ１をホルダ６０に対して前進させる場合は、中立位置にあるカバー４の辷止凹凸２４に指を掛けてこれを前動させる。
そうすると、図７に示す如く、カバー４が前動位置になり、前側の解除突起２７に依りバネ５の前傾弾片２９とホルダ６０の掛止凹部６６との掛合のみが解除され、同状態が保たれたままベース２とボディ３とカバー４が一緒に前進し、刃体７０も前進する。
この時、バネ５の後傾弾片３０は、ホルダ６０の掛止凹部６６に掛合離脱を繰返し、スライダ１が所謂ステップスライドする。
カバー４から指を放すと、スライダ１の前進が停止され、図６に示す如く、バネ５の前傾弾片２９がホルダ６０の掛止凹部６６に掛合すると共に、前傾弾片２９の弾力に依り前側の解除突起２７を介してカバー４が中立位置に戻る。
【００１７】
スライダ１をホルダ６０に対して後進させる場合は、中立位置にあるカバー４の辷止凹凸２４に指を掛けてこれを後動させる。
そうすると、カバー４が後動位置になり、後側の解除突起２７に依り後傾弾片３０とホルダ６０の掛止凹部６６との掛合のみが解除され、同状態が保たれたままベース２とボディ３とカバー４が一緒に後進し、刃体７０も後進する。
この時、バネ５の後傾弾片３０は、ホルダ６０の掛止凹部６６に掛合離脱を繰返し、スライダ１が所謂ステップスライドする。
【００１８】
金属製のベース２に合成樹脂製のボディ３がアウトサート成形されているので、落下等に依り衝撃が加わってもこれらが分解する事がない。
ベース２とボディ３とカバー４で囲まれる内部には、バネ５が収容されて抜止手段６に依りボディ３とカバー４とが合体される。つまり、ベース２とカバー４とは、ボディ３を介して取付けられているので、落下等に依り衝撃が加わっても、合成樹脂製のボディ３が衝撃を吸収し、抜止手段６が折損される事がないと共に、ボディ３とカバー４が分解され難くなる。
もし、分解されても、抜止手段６に依りボディ３とカバー４を再び合体する事が可能となる。
【００１９】
ボディ３の平板部１５を次段の刃体７０の表面に当合させる事ができると共に、ボディ３の***部１６の下面をホルダ６０の下部表壁６４の上縁に当合でき、これら平板部１５及び***部１６を合成樹脂に依り作製しているので、金属製のホルダ６０や刃体７０に対して円滑な摺動が行なえる。つまり、金属製どうしの摺動は、金属粉が発生してこれに依り摩耗が促進され易かった。
【００２０】
尚、カバー４は、先の例では、合成樹脂製であったが、これに限らず、例えば金属製でも良い。
バネ５は、先の例では、ベース２とは別体であったが、これに限らず、例えばベース２と一体であっても良い。この場合、バネ５の一部とボディ３とは、ベース２とボディ３と同様にアウトサート成形に依り一体化しても良い。
バネ５は、先の例では、金属製であったが、これに限らず、例えば合成樹脂製でも良い。この場合、バネ５とボディ３とを一体的に作製しても良い。
カバー４とバネ５と抜止手段６は、先の例では、オートロック式にする為に、カバー４に解除突起２７を設け、バネ５を前傾弾片２９と後傾弾片３０とを備えた略Ｖ型のものにし、抜止手段６の抜止部３１，３２を前後動可能にしたが、これに限らず、例えば標準式にする場合には、解除突起２７を省略し、バネ５をホルダ６０の掛止凹部６６の一つに弾合する山型のものにし、抜止手段６の抜止部３１，３２を前後動不能にしても良い。
バネ５は、先の例では、前傾弾片２９が前側で後傾弾片３０が後側の略Ｖ型であったが、これに限らず、例えば前傾弾片２９が後側で後傾弾片３０が前側の略ム型でも良い。
【００２１】
【発明の効果】
以上、既述した如く、本発明に依れば、次の様な優れた効果を奏する事ができる。
（１） ベース、ボディ、カバー、バネ、抜止手段とで構成し、とりわけ金属製のベースに合成樹脂製のボディをアウトサート成形に依り一体化すると共に、この様にしたボディとカバーとをこれらの間に設けた抜止手段に依り合体する様にしたので、落下等に依り衝撃が加わっても構成部品が分解し難いと共に、分解しても再組立が行なえる。
（２） 金属製のベースに合成樹脂製のボディをアウトサート成形に依り一体化したので、この合成樹脂製のボディを金属製のホルダや刃体に当合させる事ができ、これらの間の摺動を円滑に行なう事ができる。

BACKGROUND OF THE INVENTION
The present invention relates to a cutter knife slider, and more particularly to an improvement of a slider used for a magazine type cutter knife.
[0002]
[Prior art]
Conventionally, as sliders of this kind of cutter knife, for example, those described in Japanese Utility Model Publication Nos. 53-45358 and 62-41725 are known.
These are basically a metal base provided with a connecting projection for connecting to the blade body, a cover positioned on the front side of the base, and an inner part surrounded by the base and the cover, and a part thereof. The spring comprises a spring that is impacted and elastically engaged with the latching recess of the holder, and a retaining means that is provided between the base and the cover and unites them.
[0003]
[Problems to be solved by the invention]
However, such a device is provided with a retaining means between the base and the cover, and since the base is made of metal, when an impact is applied due to dropping or the like, the base side of the retaining means is deformed. When it was used as it was, the cover rattled against the base and the deformation was repeated, and finally the deformed part broke and it was easy to disassemble both. Further, when disassembled, there is a problem that there is a breakage point, so that reassembly cannot be performed.
The present invention was devised in view of the above-mentioned problems to solve this problem. The purpose of the present invention is to make it difficult for components to be disassembled even if an impact is applied due to dropping or the like. The present invention provides a cutter knife slider which can be reassembled even if disassembled.
[0004]
[Means for Solving the Problems]

In addition, the synthetic resin body 3 having the central raised portion 16 having the receiving hole 18 having the retaining portion 31 in the central portion, and the forwardly inclined piece 29 and the rearwardly inclined toward both sides of the bottom side 28 obliquely upward. An elastic piece 30 is formed to extend, and the forward inclined piece 29 and the backward inclined piece 30 are inserted into the receiving grooves 20, 20 and attached to the metal base 2. , 30 to the two latching recesses 66, 66 separating the holder 60. The strip-shaped spring 5 stopped, the rectangular front wall 23 having the upper wall 21 and the lower wall 22 at the upper and lower ends in the longitudinal direction, and projecting forward from one side of the front wall 23, The retaining means 6 having the retaining portion 32 inserted into the receiving hole 18 of the central raised portion 16 and hooked to the receiving hole 18, and the positions corresponding to both ends of the central raised portion 16 of the front wall 23. Projecting downward from the upper wall 21, the front wall 23 is moved forward to release the engagement of the forwardly inclined bullet piece 29 and the latching recess 66. A cover which is integrally formed with two release protrusions 27 and 27 for releasing the engagement between the bullet piece 30 and the latching recess 66 and is fitted to the metal base 2 and the synthetic resin body 3 so as to be movable back and forth. 4 is a basic configuration of the invention.
[0005]
Since the synthetic resin body is outsert-molded on the metal base, it will not be disassembled even if an impact is applied due to dropping or the like.
A spring is accommodated in the interior surrounded by the base, the body, and the cover, and the body and the cover are united by the retaining means. In other words, since the base and the cover are attached via the body, even if an impact is applied due to dropping or the like, the synthetic resin body absorbs the impact and the retaining means is not broken. The body and cover are difficult to disassemble.
Even if it is disassembled, the body and the cover can be combined again by the retaining means.
[0006]

After the cover 4 is arranged on the front side of the body 3, when the retaining part 32 of the cover 4 is applied to the front side of the retaining part 31 of the body 3 and the cover 4 is strongly pressed to the body 3 side, the space between the upper and lower retaining parts 31 expands. The retaining portion 31 and the retaining portion 32 are engaged with each other so that they cannot be detached. In other words, hell is fitted or killed. Then, the majority of the front side of the raised portion 16 of the body 3 is accommodated in the accommodation cavity surrounded by the upper wall 21, the lower wall 22, and the front wall 23 of the cover 4, and the front and rear release protrusions 27 are The cover 4 is assembled to the body 3 so as to be able to move back and forth. At this time, the housing groove 20 of the body 3 is closed by the cover 4, so that the spring 5 does not come off, and the spring 5 is housed inside the base 2, the body 3 and the cover 4. Thus, only the free ends of the forwardly inclined piece 29 and the backwardly inclined piece 30 are projected on the upper side of the raised portion 16 of the body 3.
In the assembled slider 1, concave grooves are formed above and below the raised portion 16 depending on the base 2, the body 3, and the cover 4. Thus, the slider 1 is inserted into the upper and lower concave grooves so that the upper surface wall 63 and the lower surface wall 64 of the holder 60 can be moved back and forth so that the upper surface wall 63 and the lower surface wall 64 face the inside. It is inserted and connected to the connecting hole 71 of 70. The holder 60 is loaded with a magazine (not shown) containing a plurality of blades 70 and is connected to the slider 1 in order from the blade 70 on the most front side.
[0015]
Next, the operation will be described based on such a configuration.
FIG. 6 shows a case where the slider 1 is stopped with respect to the holder 60 and is in a so-called auto-lock state.
At this time, the cover 4 is in a neutral position, and each free end portion of the forwardly inclined bullet piece 29 and the backwardly inclined bullet piece 30 of the spring 5 is separated from two hooking recesses 66 of the holder 60 which are separated from each other. It engages with the stop recess 66. For this reason, the lower surface of the raised portion 16 of the body 3 is brought into contact with the upper edge of the lower front wall 64 of the holder 60.
The front and rear release protrusions 27 are located between the free end portions of the forwardly inclined bullet piece 29 and the backward inclined bullet piece 30 of the spring 5 depending on the elasticity thereof. Is allowed.
In this state, when the slider 1 moves forward through the blade body 70, the forward inclined piece 29 and the latching recess 66 are engaged with each other, and therefore the forward inclined piece 29 functions as a so-called thrust support rod. This is blocked.
On the contrary, when the slider 1 tries to move backward through the blade body 70, the rearwardly inclined bullet piece 30 and the latching recess 66 are engaged with each other, so that the rearwardly inclined bullet piece 30 functions as a so-called thrust support rod. Be blocked.
Therefore, the blade body 70 and the slider 1 do not move in any of the front and rear directions even when an external force is applied, and are so-called auto-locked with respect to the holder 60.
[0016]
When the slider 1 is moved forward with respect to the holder 60, a finger is put on the tacking irregularities 24 of the cover 4 in the neutral position to move it forward.
Then, as shown in FIG. 7, the cover 4 is moved to the forward movement position, and only the engagement between the forwardly projecting elastic piece 29 of the spring 5 and the latching recess 66 of the holder 60 is released by the front release protrusion 27, and the same state. The base 2, the body 3, and the cover 4 are moved forward together while the blade body 70 is moved forward.
At this time, the rearwardly projecting piece 30 of the spring 5 repeatedly engages and disengages from the retaining recess 66 of the holder 60, so that the slider 1 performs a so-called step slide.
When the finger is released from the cover 4, the forward movement of the slider 1 is stopped. As shown in FIG. 6, the forwardly inclined piece 29 of the spring 5 is engaged with the engaging recess 66 of the holder 60 and the elasticity of the forwardly inclined piece 29 is obtained. Accordingly, the cover 4 returns to the neutral position via the release protrusion 27 on the front side.
[0017]
When the slider 1 is moved backward with respect to the holder 60, the finger is put on the tacking irregularities 24 of the cover 4 in the neutral position and moved backward.
Then, the cover 4 is in the rearward movement position, and only the engagement between the rearwardly inclined piece 30 and the engagement recess 66 of the holder 60 is released by the release protrusion 27 on the rear side, and the same state is maintained. The body 3 and the cover 4 move backward together, and the blade body 70 also moves backward.
At this time, the rearwardly projecting piece 30 of the spring 5 repeatedly engages and disengages from the retaining recess 66 of the holder 60, so that the slider 1 performs a so-called step slide.
[0018]
Since the synthetic resin body 3 is outsert-molded on the metal base 2, even if an impact is applied due to dropping or the like, they are not decomposed.
A spring 5 is accommodated in the interior surrounded by the base 2, the body 3, and the cover 4, and the body 3 and the cover 4 are joined together by the retaining means 6. That is, since the base 2 and the cover 4 are attached via the body 3, even if an impact is applied due to dropping or the like, the synthetic resin body 3 absorbs the impact and the retaining means 6 is broken. There is nothing, and the body 3 and the cover 4 are difficult to be disassembled.
Even if disassembled, the body 3 and the cover 4 can be combined again by the retaining means 6.
[0019]
The flat plate portion 15 of the body 3 can be brought into contact with the surface of the blade 70 at the next stage, and the lower surface of the raised portion 16 of the body 3 can be brought into contact with the upper edge of the lower surface wall 64 of the holder 60. Since the portion 15 and the raised portion 16 are made of synthetic resin, smooth sliding with respect to the metal holder 60 and the blade body 70 can be performed. In other words, the sliding between the metal made metal powder, and it was easy to promote wear.
[0020]
In the above example, the cover 4 is made of synthetic resin. However, the cover 4 is not limited to this and may be made of metal, for example.
In the previous example, the spring 5 is separate from the base 2, but is not limited thereto, and may be integrated with the base 2, for example. In this case, a part of the spring 5 and the body 3 may be integrated by outsert molding in the same manner as the base 2 and the body 3.
In the previous example, the spring 5 is made of metal. However, the spring 5 is not limited thereto, and may be made of synthetic resin, for example. In this case, the spring 5 and the body 3 may be manufactured integrally.
In the previous example, the cover 4, the spring 5, and the retaining means 6 are provided with a release protrusion 27 on the cover 4, and the spring 5 is provided with a forwardly inclined bullet piece 29 and a backwardly inclined bullet piece 30 in order to be an automatic lock type. However, in the case of a standard type, for example, the release protrusion 27 is omitted and the spring 5 is attached to the holder. It is also possible to make it a mountain shape that elastically fits into one of the 60 latching recesses 66 so that the retaining portions 31, 32 of the retaining means 6 cannot be moved back and forth.
In the previous example, the spring 5 was substantially V-shaped with the forward inclined piece 29 on the front side and the backward inclined piece 30 on the rear side. The slanting piece 30 may be a substantially um shape on the front side.
