Description

本発明は、帆立貝の耳吊り式養殖に用いる係止ピンの改良に関するものである。   The present invention relates to an improvement of a locking pin used for scalloped shell culture.

帆立貝の養殖において、ロープに該ロープに直交するように係止ピンを通し、帆立貝の稚貝の耳片に穿孔した穿孔部を該係止ピンに挿通・係合して係止し、ロープを海中に投入して養殖する帆立貝の耳吊り式養殖に用いられる係止ピンは従来から知られている（特許文献１参照）。   In scallop farming, a locking pin is passed through the rope so as to be orthogonal to the rope, and a pierced portion drilled in the ear piece of the scallop juvenile is inserted into and engaged with the locking pin and locked. A locking pin used for ear-hanging culture of scallops that are introduced into the sea for culturing is known (see Patent Document 1).

特開２００３−５２２７０号公報JP 2003-52270 A

特許文献１の図４を図８として再掲し、又特許文献１の図５を図９として再掲した。図中の符号は新たに付り直した。
図８に示されているように、係止ピン１０１は、細長い軸部１０２の端部に設けられた挿入部１０３ａの軸方向内方部位に、係止片１０５を径方向外方で軸方向内方に向けて傾斜するように突設されており、軸部１０２の係止片１０５を設けた部分には、軸方向に先端部から軸方向内方に向かって傾斜面となる係止片１０５の収容部１０２ａが設けられている。 FIG. 4 of Patent Document 1 is shown again as FIG. 8, and FIG. 5 of Patent Document 1 is shown again as FIG. The reference numerals in the figure are newly added.
As shown in FIG. 8, the locking pin 101 has an axially outwardly extending locking piece 105 at an axially inner portion of the insertion portion 103 a provided at the end of the elongated shaft portion 102. A locking piece is provided so as to incline toward the inside, and is provided on the portion of the shaft portion 102 provided with the locking piece 105 so as to become an inclined surface in the axial direction from the tip portion toward the axially inward direction. 105 accommodating portions 102a are provided.

係止片１０５は、基部（軸部１０２に連続し合流する部分）が先端部方向に肉厚で、先部（軸方向内方に延び、径方向外方に湾曲して延びる先部）は、その肉厚が先部に向かって漸減している。
係止片１０５は、挿入部１０４ａを先端部に設けた他端部１０４にも同様に１０６として設けられており、前記係止片１０３とは対称形状であり、軸部１０２の両端部１０３，１０４の軸方向内方に互いに差し込み方向とは反対方向に、径方向外方で同方向傾斜延出する係止片１０５，１０６が設けられている。 The locking piece 105 has a base portion (a portion joining and joining the shaft portion 102) that is thick in the tip portion direction, and a tip portion (a tip portion that extends inward in the axial direction and extends in a radially outward direction). The wall thickness gradually decreases toward the tip.
The locking piece 105 is also provided as 106 at the other end 104 provided with the insertion portion 104a at the tip, and is symmetrical to the locking piece 103. Locking pieces 105 and 106 that extend in the same direction in the radially outward direction are provided in the axially inward direction of 104 in the direction opposite to the insertion direction.

以上の係止ピン１０１は、図９に示されているようにロープ１２１に直交するように保持穴１２２に通して貫通保持させ、軸部１０２の中間部に設けたロープ抜止片１０７，１０８の間にロープ１２１は位置しており、係止ピン１０１はロープ１２１から抜け止めされる。
係止ピン１０１の両端部の挿入部１０４，１０５を帆立貝１２３の耳片１２３ａに穿設した係止孔１２３ｂに挿入・貫通させ、帆立貝１２３を係止ピン１０１の両端部に係止し、係止ピン１０１を介してロープ１２１に係止した帆立貝は、ロープ１２１を海中に投入し、耳吊り養殖を実施するものである。 As shown in FIG. 9, the above locking pin 101 is passed through and held through the holding hole 122 so as to be orthogonal to the rope 121, and the rope retaining pieces 107 and 108 provided in the intermediate portion of the shaft portion 102. The rope 121 is located between them, and the locking pin 101 is prevented from coming off the rope 121.
The insertion portions 104 and 105 at both ends of the locking pin 101 are inserted and penetrated into locking holes 123b formed in the ear pieces 123a of the scallop 123, and the scallop 123 is locked to both ends of the locking pin 101. The scallops locked to the rope 121 via the stop pin 101 are used to carry out the ear suspension culture by throwing the rope 121 into the sea.

以上の係止ピン１０１において、係止ピン１０１の先端部の挿入部１０３を帆立貝１２３の耳片１２３ａに穿設した係止孔１２３ｂに挿通する際、係止片１０５は係止孔１２３ｂの通過時に撓んで軸部１０２の先部に設けた収容部１０２ａに重なって収容され、軸部先部、係止片１０５を含むこの部分の外径は軸部と同等或いは略同等となり、係止孔１２３ｂを容易に通過し、係止孔１２３ｂの通過後に係止孔１２３ｂの拘束が無くなり、係止片１０５は弾性的に径方向外方に湾曲するように復帰し、図９の左側に示したように係止片１０５が抜け止めとして機能する。   In the locking pin 101 described above, when the insertion portion 103 at the tip of the locking pin 101 is inserted into the locking hole 123b formed in the ear piece 123a of the scallop 123, the locking piece 105 passes through the locking hole 123b. The outer diameter of this portion including the shaft portion tip portion and the locking piece 105 is equal to or substantially the same as that of the shaft portion, being bent and sometimes overlapped with the receiving portion 102a provided at the tip portion of the shaft portion 102. 123b easily passes through, and after passing through the locking hole 123b, the locking hole 123b is not restrained, and the locking piece 105 returns to be elastically curved radially outward, as shown on the left side of FIG. Thus, the locking piece 105 functions as a retaining member.

以上において、係止ピン１０１の帆立貝耳片１２３ａの係止孔１２３ｂを通過する際、係止片１０５又は１０６が撓み、係止ピン１０１の軸部１０２の収容部１０２ａに重なるものであるが、係止片１０５の内側面（収容部１０２ａに対向する面）が平坦であり、又収容部１０２ａの外側面（係止片１０５）の内側面に対向する面）が平坦である。   In the above, when passing through the locking hole 123b of the scallop ear piece 123a of the locking pin 101, the locking piece 105 or 106 bends and overlaps the accommodating portion 102a of the shaft portion 102 of the locking pin 101. The inner surface of the locking piece 105 (the surface facing the housing portion 102a) is flat, and the outer surface of the housing portion 102a (the surface facing the inner surface of the locking piece 105) is flat.

従って、係止片１０５を含む軸部１０２のこの部分が耳片１２３ａの係止孔１２３ｂを通過する際、係止片１０５の接する面と、対向する収容部１０２ａの接する面との間に拘束が無く、係止片１０５が収容部１０２ａに向かって閉じ動作を行う際、軸部の径方向外方に偏る虞があり、係止孔１２３ｂの通過時の抵抗となる虞がある。
この結果、係止ピン１０１への帆立貝１２３の迅速な耳吊り作業を阻害する虞があり、作業効率の妨げとなる虞があり、又帆立貝１２３への係止ピン１０１の自動装着作業（自動ピン打ち）の円滑化にも影響を及ぼす虞がある。 Therefore, when this portion of the shaft portion 102 including the locking piece 105 passes through the locking hole 123b of the ear piece 123a, the portion between the surface where the locking piece 105 contacts and the surface where the opposing storage portion 102a contacts is restrained. However, when the locking piece 105 performs the closing operation toward the housing portion 102a, there is a possibility that the shaft portion is biased outward in the radial direction, and there is a possibility that resistance is caused when the locking hole 123b passes.
As a result, there is a risk of hindering a quick ear-hanging operation of the scallop 123 to the locking pin 101, which may hinder work efficiency, and an automatic mounting operation of the locking pin 101 to the scallop 123 (automatic pin) There is also a possibility of affecting the smoothness of the strike.

本発明の実施の形態を添付図に基づいて以下に説明する。
なお、図面は符号の向きに見るものとする。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
The drawings are viewed in the direction of the reference numerals.

図１は、係止ピンの全体を示す正面図であり、係止ピン１は、細長い中実な軸部２と、軸部２の両端部の少々尖鋭な挿入部３，３と、挿入部３，３の軸方向内方に設けた係止部４，４と、軸部２の軸方向中間部に設けた抜止部７，７とを備える。   FIG. 1 is a front view showing the entire locking pin. The locking pin 1 includes an elongated solid shaft portion 2, slightly sharp insertion portions 3 and 3 at both ends of the shaft portion 2, and an insertion portion. 3 and 3, locking portions 4, 4 provided in the axially inward direction, and retaining portions 7, 7 provided in the axially intermediate portion of the shaft portion 2.

端部の挿入部３，３は最先端部が軸部２よりも十分に小径で先端部３ａは半球状をなし、前述した帆立貝の耳片に設けた係止孔よりも小径であり、係止孔に挿入し易い形状である。
挿入部３の先端部から軸方向の後方に延びる中間部〜後部の本体部３ｂは後方に外径が次第に拡径するように円錐状をなし、本体部３ｂの軸方向内方である後端直後に、この部分から後方に向けて係止部４が形成されている。 The insertion portions 3 and 3 at the end have a diameter that is sufficiently smaller than that of the shaft portion 2 and the tip portion 3a has a hemispherical shape and a diameter that is smaller than the locking hole provided in the ear piece of the scallop described above. It is a shape that can be easily inserted into the blind hole.
The intermediate part-rear part main body part 3b extending rearward in the axial direction from the distal end part of the insertion part 3 has a conical shape so that the outer diameter gradually increases rearwardly, and is the rear end that is inward in the axial direction of the main body part 3b. Immediately after that, a locking portion 4 is formed from this portion toward the rear.

係止部４は、軸方向内方に延びる係止片５で構成されており、係止片５は、軸内方に軸方向に延出されており、後上方（軸部の軸方向内方で上方）に向けて湾曲して延出され、係止片５の基部５ａに下軸部６の先部６ａが連続している。
軸方向内方（後方）に向けて延びる下側の下軸部６は、軸部２の他の部分よりも上下の
厚さが薄く、軸部２の軸方向内方（後方）に向けて厚さが漸増し、係止片５と重ね合わせ
た状態で軸部２の外径と一致するか、或いは略々一致するように設定されている。
挿入部３、係止片５で構成される係止部４を含む係止ピン１の先部は、図１、図２、図３、図５，６に示したように、レ形をなす。 The locking portion 4 is configured by a locking piece 5 that extends inward in the axial direction. The locking piece 5 extends inward in the axial direction in the axial direction, and the rear upper side (in the axial direction of the axial portion). And the tip 6a of the lower shaft 6 is continuous with the base 5a of the locking piece 5.
The lower lower shaft portion 6 that extends inward (backward) in the axial direction is thinner in the upper and lower thickness than the other portions of the shaft portion 2, and faces inward (backward) in the axial direction of the shaft portion 2. The thickness gradually increases, and is set so as to coincide with or substantially coincide with the outer diameter of the shaft portion 2 in a state where the thickness overlaps with the locking piece 5.
As shown in FIGS. 1, 2, 3, 5, and 6, the tip portion of the locking pin 1 including the insertion portion 3 and the locking portion 4 including the locking piece 5 has a re-shape. .

以上により、係止片５が下軸部６上に重なった際に、係止片５を収容する収容部６ｃを構成する。
係止片５の下面が下軸部６の上面に接するように重なった際、図４（ｂ）に示すように円形断面となるように構成されている。 As described above, when the locking piece 5 overlaps the lower shaft portion 6, the accommodating portion 6 c that accommodates the locking piece 5 is configured.
When the lower surface of the locking piece 5 overlaps with the upper surface of the lower shaft portion 6, it is configured to have a circular cross section as shown in FIG.

以上の下軸部６の軸方向内方部分から前述の抜止部７，７に向かって軸部がその外径を漸増して太くなり、抜止部７，７は実施例で係止片５，５と同様に径方向外方に対称に向かい合うように突出してハ字形となる。
軸部中間部に設けたハ字形の抜止部７，７の間には、実施例では、軸方向に離間して断面十字片の脆弱部８，８を２カ所設ける。 The shaft portion gradually increases in outer diameter from the axially inner portion of the lower shaft portion 6 toward the retaining portions 7, 7 described above, and the retaining portions 7, 7 become the locking pieces 5 in the embodiment. Like 5, it protrudes so as to face the outer side in the radial direction so as to be symmetrical.
In the embodiment, two weak portions 8 and 8 having cross-sectional cross sections are provided between the C-shaped retaining portions 7 and 7 provided at the intermediate portion of the shaft portion so as to be separated from each other in the axial direction.

これにより、帆立貝の水揚げ時に帆立貝に過大な力が作用した際、係止ピンの抜止片内側の脆弱部８，８から切断される。
これにより、抜止部７，７の一方の残留による残留係止ピンによるロープへの残留を無くし、ロープからの抜脱帆立貝をロープから離脱させて収穫を円滑に行わせるとともに、脆弱部８，８の破断により抜止部７，７がロープに引っ掛かることが無くなり、水揚げ後の係止ピンをロープから離脱させることができる。 Accordingly, when an excessive force is applied to the scallop when the scallop is landed, the scallop is cut from the fragile portions 8 and 8 inside the retaining piece of the locking pin.
This eliminates the residue on the rope due to the residual locking pin due to one residue of the retaining portions 7 and 7, allows the scallops to be removed from the rope to be detached from the rope, and the harvesting is performed smoothly, and the fragile portions 8 and 8. The retaining portions 7 and 7 are not caught by the rope due to the breakage of, so that the locking pin after landing can be detached from the rope.

図２は、係止ピンの先部を軸方向内方から見た拡大斜視図で、先部を断面として示した説明図であり、係止片５の下面９と、この下面９と向かい合う下軸部６の上面１０には段差部１１，１２を設ける。   FIG. 2 is an enlarged perspective view of the tip portion of the locking pin viewed from the inside in the axial direction, and is an explanatory view showing the tip portion as a cross section. The lower surface 9 of the locking piece 5 and the lower surface 9 facing the lower surface 9 are shown. Step portions 11 and 12 are provided on the upper surface 10 of the shaft portion 6.

段差部は以下の通りである。
係止片５の下面９に形成した段差部１１は、図４（ａ）で示したように、幅方向（図の左右方向）の中心部で図の左側が下方に突出した凸面１１ａであり、図の右側が上方の潜った凹面１１ｂである。
一方、下軸部６の上面１０に形成した段差部１２は、図４（ａ）で示したように図の左側が下方に潜った凹面１２ａであり、図の右側が上方に突出した凸面１２ｂである。 The step portion is as follows.
As shown in FIG. 4A, the step portion 11 formed on the lower surface 9 of the locking piece 5 is a convex surface 11a that protrudes downward on the left side in the center of the width direction (left-right direction in the drawing). The right side of the figure is the concave surface 11b that is submerged above.
On the other hand, the stepped portion 12 formed on the upper surface 10 of the lower shaft portion 6 is a concave surface 12a that dives downward on the left side of the drawing as shown in FIG. 4A, and a convex surface 12b that protrudes upward on the right side of the drawing. It is.

段差部１１，１２は、係止片５、下軸部６の基部５ａ，６ａに近い部分の凸面１１ａが上下方向に厚く、また凹面１１ｂが深く、係止片５の湾曲した先部５ｂ及び下軸部６の軸方向内方部位（先部５ｂの対向部）６ｂが薄く、また浅い。
段差部１１，１２は、基部から先部にかけて深さ及び凸出高さが小さくなってゆき、係止片５を下軸部６に近接させ、重ね合わせた際、即ち、図４（ａ）の状態から同（ｂ）の状態に移行した際、双方の段差面１３，１４は、軸部の中心に対して直交する壁面となり、段差面１３，１４が接触するように、一方の凸面１１ａが他方の凹面１２ａに接触し、他方の凸面１２ｂが凹面１１ｂに接触する。 The step portions 11 and 12 include the locking piece 5, the convex surface 11 a near the base portions 5 a and 6 a of the lower shaft portion 6 is thick in the vertical direction, the concave surface 11 b is deep, the curved tip portion 5 b of the locking piece 5, and The axially inward portion of the lower shaft portion 6 (opposite portion of the front portion 5b) 6b is thin and shallow.
The stepped portions 11 and 12 are reduced in depth and protruding height from the base portion to the tip portion, and when the locking pieces 5 are brought close to the lower shaft portion 6 and overlapped, that is, FIG. When the state is shifted from the state (b) to the state (b), both the step surfaces 13 and 14 become wall surfaces orthogonal to the center of the shaft portion, and the one convex surface 11a so that the step surfaces 13 and 14 come into contact with each other. Is in contact with the other concave surface 12a, and the other convex surface 12b is in contact with the concave surface 11b.

ところで、係止ピン１の先部の挿入部３を貝の耳片の係止孔に半球状の先端部３ａを挿入し、係止ピン１を押し込んでゆく。
係止片５、下軸部６は貝耳片の係止孔に到り、係止片５は可撓弾性を有するので下軸部６方向に撓んで倒れ、図４（ａ）の状態から閉じる方向に移行し、最終的には同（ｂ）のように段差部１１，１２は閉じて段差面１３，１４は相互に接触する。 By the way, the insertion part 3 at the tip of the locking pin 1 is inserted into the locking hole of the shell piece and the hemispherical tip 3a is inserted, and the locking pin 1 is pushed in.
The locking piece 5 and the lower shaft portion 6 reach the locking hole of the shell ear piece, and since the locking piece 5 has flexible elasticity, it bends and falls in the direction of the lower shaft portion 6, from the state of FIG. In the closing direction, the stepped portions 11 and 12 are finally closed and the stepped surfaces 13 and 14 are in contact with each other as shown in FIG.

これにより、図４（ｂ）に示されるように係止片５と下軸部６は閉じ、係止片５は下軸部６の収容部６ｃに収容されて係止ピンのこの部分は閉じた狭窄状態となり、その断面は円形をなし、外径は小さい。
このように段差部１１，１２、段差面１３，１４の接触により、係止片５、下軸部６は接触し、この状態で貝の耳片に設けた係止孔（耳吊り穴）に係止ピン１の先部の挿入部３を差し込み後、通過し、この挿通時に、係止片５、下軸部６は夫々が左右にズレて係止孔に引っ掛かったり、押し込み抵抗となることが少なく、容易に、円滑に係止ピン１の係止部４は貝耳片の係止孔を通過する。 As a result, the locking piece 5 and the lower shaft portion 6 are closed as shown in FIG. 4B, and the locking piece 5 is received in the receiving portion 6c of the lower shaft portion 6 and this portion of the locking pin is closed. The cross section is circular and the outer diameter is small.
As described above, the contact between the stepped portions 11 and 12 and the stepped surfaces 13 and 14 brings the locking piece 5 and the lower shaft portion 6 into contact, and in this state, the locking holes (ear hanging holes) provided in the shell ear pieces. After inserting the insertion portion 3 at the tip of the locking pin 1, it passes, and at the time of this insertion, the locking piece 5 and the lower shaft portion 6 are shifted to the left and right to be caught in the locking hole or become push resistance. The locking portion 4 of the locking pin 1 passes through the locking hole of the shell ear piece easily and smoothly.

通過後は、係止片５は貝耳片の係止孔の拘束を脱する。
爾後、係止片５は弾性により径方向外方に突出復帰し、貝耳片の係止孔からの係止ピンの離脱を阻止する。
図４（ｃ）は係止片５の貝耳片係止孔通過後の状態を示している。 After passing, the locking piece 5 releases the restraint of the locking hole of the shell ear piece.
After the dredging, the locking piece 5 protrudes and returns outward in the radial direction due to elasticity, and prevents the locking pin from being detached from the locking hole of the shell ear piece.
FIG. 4C shows a state after the locking piece 5 has passed through the shell ear piece locking hole.

以上の係止ピン１は、各部全一体に合成樹脂で形成されている。合成樹脂としては、例えば６６ナイロン等を用いた。
その理由は、帆立貝を係止ピンで係止し、海中に侵浸した際、海中で水分を吸収し、これにより少し柔らかくなり、また、伸ばすと約３倍程度延伸するので、６６ナイロン等を用いたものである。 The above locking pin 1 is formed of synthetic resin in all parts. For example, 66 nylon or the like was used as the synthetic resin.
The reason is that when the scallop is locked with a locking pin and invades the sea, it absorbs moisture in the sea, making it a little softer, and when stretched, it stretches about 3 times. It is what was used.

ところで係止部４（係止片５）には極めて大きな過重が作用する。つまりは、帆立貝の生育に従い重量が増加すること、また、海藻やフジツボ等の雑物の付着により更に重量は増加すること、さらに、波浪や水揚げ時の抵抗によって貝を保持する係止ピン係止部下側（係止片５の基部５ａ）の下軸部６には大きな引張力が作用する。
この結果、下軸部６の基部６ａが破断して貝が落下してしまう場合がある。
係止ピンの破断箇所は、概ね係止部４（係止片５）の基部５ａであって下軸部６の係止部に近い付け根部分（基部６ａ）付近である。 By the way, an extremely large weight acts on the locking portion 4 (locking piece 5). In other words, the weight increases with the growth of scallops, the weight further increases due to the adhesion of seaweeds, barnacles, and other contaminants. A large tensile force acts on the lower shaft portion 6 on the lower portion side (the base portion 5a of the locking piece 5).
As a result, the base part 6a of the lower shaft part 6 may break and the shellfish may fall.
The breakage point of the locking pin is approximately the base portion 5a of the locking portion 4 (locking piece 5) and the vicinity of the base portion (base portion 6a) close to the locking portion of the lower shaft portion 6.

本発明では、この部分に段差部１１，１２が設けてあり、断面積は段差部が無い場合と同一である場合には、その破断強度は段差部が無い場合よりも上昇する傾向にある。
従って、本発明では段差部１１，１２が形成されているため、係止部、下軸部の破断強度の向上に資するということができる。 In the present invention, the step portions 11 and 12 are provided in this portion, and when the cross-sectional area is the same as when there is no step portion, the breaking strength tends to be higher than when there is no step portion.
Therefore, in the present invention, since the step portions 11 and 12 are formed, it can be said that it contributes to improvement of the breaking strength of the locking portion and the lower shaft portion.

図７は、本発明の他の実施例を示す図で、（ａ）は係止部が下軸部から離間した状態の図、（ｂ）は係止部が下軸部に重なった状態の図、（ｃ）は（ｂ）から係止部が下軸部から離間して開いた状態の図である。
本実施例は、係止片５の下面５９、下軸部６の上面６０に設けた段差部６１，６２の対向する段差面６３，６４を向かい合う対称な傾斜面としたものである。 FIGS. 7A and 7B are diagrams showing another embodiment of the present invention, in which FIG. 7A is a diagram in which the locking portion is separated from the lower shaft portion, and FIG. 7B is a state in which the locking portion is overlapped with the lower shaft portion. (C) is a figure of the state which the latching | locking part opened apart from the lower shaft part from (b).
In the present embodiment, the opposed step surfaces 63 and 64 of the step portions 61 and 62 provided on the lower surface 59 of the locking piece 5 and the upper surface 60 of the lower shaft portion 6 are formed as symmetric inclined surfaces.

本実施例では、係止ピン１の挿入部３の先端部の貝耳片への係止孔挿通時に、係止片５及び下軸部６は相互に閉じ方向に移行するが、閉じ方向に移行した際、段差部６１，６２の段差面６３，６４が向かい合う対称の傾斜面なので、図７の（ａ）の状態から閉じ方向への移行で調心作用を行う。   In this embodiment, the locking piece 5 and the lower shaft portion 6 move toward each other in the closing direction when the locking hole is inserted into the shell ear piece at the tip of the insertion portion 3 of the locking pin 1. When the transition is made, the stepped surfaces 63 and 64 of the stepped portions 61 and 62 are symmetrically inclined surfaces facing each other, so that the alignment action is performed by shifting from the state of FIG. 7A to the closing direction.

調心作用により、係止片５、下軸部６は、段差部の傾斜段差面６３，６４に当接により、相互に図の左右方向の間の中心に移動し、閉じ作用で自動的に調心して互いに合い寄り、図７（ｂ）のようにその断面は円形をなし、外径は小さい。
図７（ｃ）は、図４（ｃ）と同様に貝耳片係止孔の通過後に係止孔の拘束を脱し、係止片５が弾性により径方向外方に突出して復帰し、貝耳片の係止孔からの係止ピンの離脱を阻止する状態を示している。 Due to the aligning action, the locking piece 5 and the lower shaft part 6 move to the center between the left and right directions in the figure by contacting the inclined step surfaces 63 and 64 of the step part, and automatically by the closing action. As shown in FIG. 7B, the cross section is circular and the outer diameter is small.
FIG. 7 (c), like FIG. 4 (c), removes the restraint of the latching hole after passing through the shell ear piece latching hole, and the latching piece 5 elastically protrudes radially outward to return. The state which prevents the detachment | leave of the latching pin from the latching hole of an ear piece is shown.
