Description

【０００１】
【発明の属する技術分野】
本発明は、外筒体と内筒体との相対回転操作により、内筒体の内部に収納した口紅等の棒状化粧料を繰り出して使用する繰り出し容器に関するものである。
【０００２】
【従来の技術】
この種の繰り出し容器において、外筒体と内筒体との相対回転操作時における外筒体と内筒体との間のガタつきを無くし、操作性の向上を図ることを目的とした技術として、特開平９−１８２６２０号公報記載のものが提案されている。
【０００３】
この従来技術は、外筒体の上端部に、内筒体を囲繞する頸部体（装着筒）を嵌着すると共に、これら外筒体と頸部体との取付部分内周に、周方向に適宜間隔をもって内筒体の外周に弾接する摺動凸部を形成した軟質弾性体から成る抵抗リングを配置し、この抵抗リングを外筒体の上面と頸部体の下面とで挟持して構成されている。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記した従来技術にあっては、抵抗リングを外筒体の上面と頸部体の下面とで挟持するように構成されているので、抵抗リングが、この上下からの押圧により、内筒体との間に隙間が形成されている内周側へ縮径するように弾性変形し、それに伴って摺動凸部の内筒体の外周面に対する押圧力が増大する方向に変化する傾向が強いため、外筒体と内筒体との相対回転操作時における抵抗感が、抵抗リングの設定寸法から得られる場合に比べて大幅に増大し、操作性が悪くなる恐れがあると云う問題があった。
【０００５】
また、抵抗リングの外筒体に対する組付けは、外筒体内に嵌装した抵抗リングを、外筒体に嵌着された頸部体と外筒体との間で上下から挟持して達成しているだけであるので、抵抗リングと内筒体との間に発生する摩擦抵抗力により、抵抗リングが外筒体に対して回動変位し易く、このため回転操作に安定性が欠けると云う問題があった。
【０００６】
そして、外筒体に対して頸部体を、抵抗リングの弾発力に抗した状態で単に嵌着するように構成されているので、この抵抗リングの弾発力が常に頸部体を離脱させる方向に作用した状態となり、このため外部からの種々の衝撃により頸部体の外筒体に対する組付きが劣化する恐れがあると云う問題があった。
【０００７】
さらに、外筒体に対する頸部体の組付けは、既に外筒体に嵌装されている抵抗リングを弾性変形させながら行う必要があるので、抵抗リングの適正な弾性変形と、外筒体に対する適正な嵌着姿勢とを留意しなければならず、組立てに熟練と取扱いの正確さとが要求され、作業性が悪いと云う問題があった。
【０００８】
そこで、本発明は、上記した従来技術における問題点を解消すべく創案されたもので、弾性リングを外筒体に弾性変形なしに、かつ回動変位不能に組付けることを技術的課題とし、もって出し入れの回転操作時における外筒体と内筒体との間のガタつき発生を防止すると共に、適正な回転抵抗感を安定して確実に得ることができ、かつ組立て作業が容易であると共に、高い構造安定性を得ることを目的とする。
【０００９】
【課題を解決するための手段】
上記技術的課題を解決する本発明の内、請求項１記載の発明の手段は、
内周面に螺溝を刻設した螺筒を内部に嵌入固定した外装筒の上端開口部に、上部分を装着機能部分とした装着筒の下部分を嵌入固定した外筒体を有すること、
上半分の収納筒部を延出させた姿勢で、縦長ガイド孔を設けた下半分にガイド筒部を挿入して、外筒体に回転自在ではあるが抜け出し不能に組付いた内筒体を有すること、
外周面に内筒体の縦長ガイド孔を貫いて外筒体の螺溝に螺合する螺合突片を突設し、内筒体内に昇降変位可能に組付いた円筒形状の受皿体を有すること、
外筒体の装着筒の装着機能部分に着脱して、内筒体の収納筒部の上端開口部を開閉する有頂筒形状のキャップ体を有すること、
上部である作用部の内周面を内筒体に弾接させた軟質弾性体から成る弾性リングを、上端面を外筒体の装着筒の下端面に下方から対向させた状態で、下部である基部で、外筒体の螺筒と外装筒との間に、周方向に係止させて嵌装組付けすること、
にある。
【００１０】
内筒体は、その上半分の収納筒部を延出させた状態で、下半分のガイド筒部を挿入させて外筒体に回転自在ではあるが抜け出し不能に組付いており、この内筒体内に受皿体が、その外周面に設けた螺合突片を内筒体のガイド筒部の縦長ガイド孔を貫いて外筒体の螺溝に螺合させた状態で昇降変位可能に組付けられているので、外筒体と内筒体との相対回転により、受皿体は、その螺合突片の螺溝に対する螺合に従って昇降変位し、これにより内筒体の収納筒部内からの保持した化粧料の出し入れを達成する。
【００１１】
弾性リングは、その基部を、螺筒と外装筒との間に、周方向に係止した状態で嵌装させて外筒体に組付いているので、この外筒体に対する組付きのために弾性変形することはなく、このため作用部を、他部からの不要な弾性変形のない、設計通りの状態で内筒体の外周面に弾接させることができ、これにより外筒体と内筒体との相対回転操作時における抵抗感が設定通りとなると共に、外筒体と内筒体との間のガタつきは防止される。
【００１２】
また、弾性リングは、その上端面を装着筒の下端面に下方から対向させているので、外筒体と内筒体との相対回動とか振動等の原因で弾性リングが螺筒と外装筒との間から上方に抜け出ようとしても、装着筒に突き当たって抜け出ることができず、弾性リングの外筒体に対する組付きは安定して保持され、またこの際の弾性リングの装着筒への突き当たり力は、きわめて微弱な力であるので、装着筒がこの突き当たりにより外装筒に対する組付きを劣化させることはない。
【００１３】
弾性リングの螺筒と外装筒と内筒体との組合せ物に対する組付けは、この組合せ物に対して弾性リングを、一定形態で弾性変形させることを要することなく、その基部を螺筒と外装筒との組合せ物に対して周方向に係止させた状態で嵌装させ、次いで装着筒を外装筒に嵌装するだけで達成される。
【００１４】
請求項２記載の発明は、請求項１記載の発明に、弾性リングに対する周方向の係止機能部分の構成を、弾性リングの基部の外周面に多数の縦溝から成るローレットを刻設し、外筒体の外装筒の内周面に、このローレットに係合する縦リブを設けたものとしたことを追加したものである。
【００１５】
弾性リングに対する周方向の係止は、縦リブのローレットに対する係止により達成されるので、弾性リングの組付けに際して、この弾性リングの周方向に沿った位置合わせを考慮する必要が全くなく、また縦リブとローレットとは周方向に係止するものであるので、外筒体と内筒体との組合せ物に対する弾性リングの嵌装組付けに邪魔となることがない。
【００１６】
請求項３記載の発明は、請求項１記載の発明に、弾性リングの上端面を、装着筒の下端面から離間させて配設したことを追加したものである。
【００１７】
弾性リングの上端面を、装着筒の下端面から離間させることにより、装着筒から弾性リングに不要な力が作用することがなく、弾性リングの内筒体に対する適正な弾接を維持することができ、また弾性リングの弾力の作用により、装着筒の外装筒に対する嵌着組付きが劣化することもない。
【００１８】
請求項４記載の発明は、請求項１記載の発明に、弾性リングを、基部を肉厚にまた作用部を肉薄に形成し、作用部の内周面略中央に、内筒体の外周面に弾接する摺接凸部を突周設すると共に、作用部の外周面上端に鍔部を突周設して構成したことを追加したものである。
【００１９】
弾性リングの基部を肉厚に構成したので、螺筒と外装筒との間への嵌装組付きを構造的に安定して達成維持し、また周方向の係止機能部分の形成を構造的にもスペース的にも、余裕を持って達成することができる。
【００２０】
また、弾性リングの作用部を肉薄に構成して、この作用部を弾性変形し易い構造とし、鍔部の外装筒内周面に対する突き当たりにより、弾性変形し易い作用部の弾性変形を両持ち状の一定した形態とし、かつ内筒体に対する弾接箇所を摺接凸部に特定したので、弾性リングの内筒体に対する弾接強度およびこの弾接強度による摩擦抵抗力の程度を設定し易く、これによりより適正な抵抗感の設定と、成形寸法誤差によるガタつきのより確実な防止とが達成される。
【００２１】
【発明の実施の形態】
以下、本発明の実施例を、図面を参照しながら説明する。
繰り出し容器１は、大別して、外筒体２と、内筒体９と、受皿体２０と、キャップ体２２と、から構成されている。
【００２２】
外筒体２は、内周面に螺溝４を刻設した合成樹脂製の直線円筒形状をした螺筒３と、この螺筒３を不動に嵌入固定した直線円筒形状の外装筒５と、この外装筒５の螺筒３よりも上方に突出した上端開口部に、外周面中央部に周設した突周部８を外装筒５の上端内周面に当接させて嵌入固定され、突周部８よりも上の筒片部分をキャップ体２２のための装着機能部分とした円筒片状の装着筒７と、から構成されている。
【００２３】
内筒体９は、略その全高さ範囲にわたって一対の縦長ガイド孔１２を開設して螺筒３に内装される、この螺筒３と略等しい高さのガイド筒部１１と、このガイド筒部１１の上端に段部１３を介して拡径連設された収納筒部１０とから構成され、その全体が金属製の円筒形状となっている。
【００２４】
軟質合成樹脂、ゴム等の軟質弾性体から成る弾性リング１４は、比較的肉厚な基部１５の上部に肉薄な作用部１７を形成し、この作用部１７の内周面略中央には、一本の周突条または周方向に適宜分割された複数の突部である摺接凸部１８が設けてあると共に、外周面上端には鍔部１９が周設してある。
【００２５】
この弾性リング１４は、その基部１５を、外筒体２の螺筒３上端部と外装筒５との間に嵌装させて外筒体２に組付けられるが、基部１５の外周面には多数の縦溝から構成されるローレット１６が刻設されていて、このローレット１６に外装筒５の内周面に突設した複数（図３図示実施例にあっては、四つ）の縦リブ６が係合して周方向から係止することにより、外筒体２と弾性リング１４との間の周方向の係止機能部分を構成している。
【００２６】
この弾性リング１４の組付き状態において、摺接凸部１８は内筒体９の収納筒部１０外周面に所定の押圧力で弾接し、鍔部１９の外周面は外装筒５の内周面に軽く当接するか、あるいはわずかに離間して、作用部１７の外周面と外装筒５の内周面との間に隙間１７ａが形成され、また弾性リング１４の上端面は装着筒７の下端面から離間している。
【００２７】
受皿体２０は、外周面に、縦長ガイド孔１２を貫いて螺溝４に螺合する螺合突片２１を突設した、内筒体９内に緩く摺動可能に嵌入する径寸法の円筒形状に形成されている。
【００２８】
キャップ体２２は、下端開口部を外筒体２の装着筒７に着脱自在に嵌装する有頂円筒形状に形成されている。
【００２９】
【発明の効果】
本発明は、上記した構成となっているので、以下に示す効果を奏する。
外筒体と内筒体との組合せ物に対する弾性リングの組付けは、この組付け達成維持のために弾性リングを強制的に弾性変形させることがないので、組付けられた弾性リングは、設計通りの力で内筒体に弾接することになり、もって確実なガタつき防止と適度の抵抗感とを得ることができ、適正で優れた操作性を発揮することになる。
【００３０】
外筒体と内筒体との組合せ物に対する弾性リングの組付きは、外筒体に対して周方向に係止して回動変位不能となっているので、弾性リングは内筒体に対して確実に摩擦接触することになり、もって弾性リングと内筒体との間に確実に摩擦抵抗力を発生させて、優れた操作性の安定性を高めることができる。
【００３１】
外装筒の上端開口部に嵌装された装着筒は、組付けられた弾性リングの組付きを押圧保持するのではなく、外筒体の嵌着組付き部分からの弾性リングの抜け出し変位を突き当たりにより阻止するだけであるので、弾性リングの組付けに関連して、その嵌装組付き状態が劣化する恐れは全くなく、もって強固で安定した組立て構造を維持する。
【００３２】
外筒体と内筒体との組合せ物に対する弾性リングの組付けは、弾性リングを一定形態で強制的に弾性変形させることなく、単に一つの方向から嵌装させれば良く、もって組立て操作がきわめて簡単で、高い作業効率を得ることができる。
【００３３】
請求項２記載の発明によれば、弾性リングと外筒体との間の周方向の係止機能部分を、多数の縦溝で構成されるローレットと縦リブとで構成したので、係止機能部分の係止組付き方向と、弾性リングの外筒体に対する嵌装組付き方向とが一致し、もって外筒体に対する弾性リングの単一の取扱い操作で、外筒体に対する弾性リングの組付けと係止とを達成でき、優れた作業効率を得ることができる。
【００３４】
請求項３記載の発明によれば、装着筒は、弾性リングの抜け出し変位を突き当たりにより阻止するだけであり、定常状態では、装着筒の外装筒に対する組付きを劣化させる力が弾性リングから全く作用せず、もって組立て構造を強固に安定して保持することができる。
【００３５】
請求項４の発明によれば、外筒体と内筒体との組合せ物に対する弾性リングの嵌装組付けを安定して達成できると共に、作用部の弾性変形を円滑にかつ一定して安定的に発揮させることができ、内筒体に対する弾接箇所を摺接凸部に特定したので、弾性リングと内筒体との間の摩擦抵抗力の設定を正確にかつ簡単に行うことができると共に、成形寸法誤差によるガタつきの発生を確実にかつ良好に防止する。

BACKGROUND OF THE INVENTION
The present invention relates to a feeding container that feeds and uses stick-shaped cosmetics such as lipsticks stored inside an inner cylinder by a relative rotation operation between the outer cylinder and the inner cylinder.
[0002]
[Prior art]
In this type of feeding container, as a technology aimed at improving the operability by eliminating rattling between the outer cylinder and the inner cylinder during the relative rotation operation between the outer cylinder and the inner cylinder. JP-A-9-182620 has been proposed.
[0003]
In this prior art, a neck part (mounting cylinder) surrounding the inner cylinder body is fitted to the upper end portion of the outer cylinder body, and a circumferential direction is attached to the inner periphery of the attachment portion between the outer cylinder body and the neck body. A resistance ring made of a soft elastic body formed with a sliding convex portion that elastically contacts the outer periphery of the inner cylindrical body at an appropriate interval is disposed between the upper surface of the outer cylindrical body and the lower surface of the neck body. It is configured.
[0004]
[Problems to be solved by the invention]
However, in the above-described conventional technology, the resistance ring is configured to be sandwiched between the upper surface of the outer cylinder and the lower surface of the neck body. There is a tendency to change in a direction in which the pressing force against the outer peripheral surface of the inner cylindrical body of the sliding convex portion increases along with elastic deformation so as to reduce the diameter toward the inner peripheral side where a gap is formed between the body and the body. Due to its strength, there is a problem that the feeling of resistance at the time of the relative rotation operation between the outer cylinder and the inner cylinder is greatly increased as compared with the case where the resistance ring is obtained from the set dimensions of the resistance ring, and the operability may be deteriorated. there were.
[0005]
Also, the assembly of the resistance ring to the outer cylinder is accomplished by sandwiching the resistance ring fitted in the outer cylinder from above and below between the neck and the outer cylinder fitted in the outer cylinder. Therefore, the resistance ring easily rotates and displaces with respect to the outer cylinder body due to the frictional resistance generated between the resistance ring and the inner cylinder body, so that the rotation operation is not stable. There was a problem.
[0006]
Since the neck body is simply fitted to the outer cylinder in a state that resists the resilience of the resistance ring, the resilience of the resistance ring always leaves the neck body. Therefore, there has been a problem that the assembling of the cervical body with respect to the outer cylinder may be deteriorated by various external impacts.
[0007]
Furthermore, since the assembly of the neck body to the outer cylinder needs to be performed while elastically deforming the resistance ring already fitted to the outer cylinder, appropriate elastic deformation of the resistance ring and the outer cylinder An appropriate fitting posture must be taken into account, and skill and accuracy of handling are required for assembling, resulting in poor workability.
[0008]
Therefore, the present invention was devised to solve the above-described problems in the prior art, and it is a technical problem to assemble the elastic ring to the outer cylindrical body without elastic deformation and incapable of rotational displacement, As a result, it is possible to prevent rattling from occurring between the outer cylinder and the inner cylinder during the rotation operation, and it is possible to stably and surely obtain an appropriate rotational resistance and to facilitate assembly work. The purpose is to obtain high structural stability.
[0009]
[Means for Solving the Problems]
Among the present invention for solving the above technical problems, the means of the invention according to claim 1 is:
Having an outer cylindrical body in which the lower part of the mounting cylinder with the upper part as a mounting function part is fitted and fixed to the upper end opening of the outer cylinder in which a screw cylinder with a thread groove formed on the inner peripheral surface is fitted and fixed;
With the upper half of the storage cylinder extended, insert the guide cylinder into the lower half with the vertically long guide holes, and attach the inner cylinder that can be rotated to the outer cylinder but cannot be pulled out. Having
There is a cylindrical receiving plate that is provided on the outer peripheral surface through a longitudinal guide hole of the inner cylindrical body and is screwed into a thread groove of the outer cylindrical body so that the inner cylindrical body can be moved up and down. thing,
A cap body having a top cylindrical shape that is attached to and detached from the mounting function portion of the mounting cylinder of the outer cylinder and opens and closes the upper end opening of the storage cylinder of the inner cylinder;
An elastic ring made of a soft elastic body with the inner peripheral surface of the upper working part elastically contacted with the inner cylinder body, with the upper end faced to the lower end surface of the mounting cylinder of the outer cylinder body from below, At a certain base, between the screw cylinder of the outer cylinder body and the outer cylinder, it is locked and assembled in the circumferential direction,
It is in.
[0010]
The inner cylinder is assembled in such a manner that the lower half of the storage cylinder is extended and the lower half of the guide cylinder is inserted so that the outer cylinder can rotate but cannot be pulled out. The saucer body is assembled in the body so that it can be displaced up and down in a state where the threaded projecting piece provided on the outer peripheral surface penetrates the longitudinal guide hole of the guide tube portion of the inner tube body and is screwed into the thread groove of the outer tube body Therefore, by the relative rotation between the outer cylinder body and the inner cylinder body, the tray body is moved up and down in accordance with the threaded engagement with the screw groove of the threaded projection piece, thereby holding the inner cylinder body from within the storage cylinder portion. Achieve in and out of cosmetics.
[0011]
The elastic ring is assembled to the outer cylinder by fitting its base portion in a circumferentially locked state between the screw cylinder and the outer cylinder. It is not elastically deformed, and therefore, the action part can be elastically contacted with the outer peripheral surface of the inner cylinder in the designed state without unnecessary elastic deformation from other parts. The feeling of resistance at the time of the relative rotation operation with the cylindrical body becomes as set, and rattling between the outer cylindrical body and the inner cylindrical body is prevented.
[0012]
Further, since the upper end surface of the elastic ring is opposed to the lower end surface of the mounting cylinder from below, the elastic ring is screwed into the outer cylinder and the outer cylinder due to relative rotation or vibration between the outer cylinder and the inner cylinder. If the elastic ring hits the mounting cylinder, it cannot be pulled out, and the assembly of the elastic ring to the outer cylinder is held stably, and the elastic ring hits the mounting cylinder at this time. Since the force is a very weak force, the mounting cylinder does not deteriorate the assembly with respect to the outer cylinder due to the contact.
[0013]
The assembly of the elastic ring to the combination of the screw cylinder, the outer cylinder and the inner cylinder does not require the elastic ring to be elastically deformed in a certain form with respect to the combination, and the base portion of the elastic ring is not required to be elastically deformed. This is achieved by fitting the cylinder in a circumferentially locked state with respect to the combination with the cylinder, and then fitting the mounting cylinder on the exterior cylinder.
[0014]
The invention according to claim 2 is the invention according to claim 1, in which the structure of the locking function portion in the circumferential direction with respect to the elastic ring is engraved, and a knurl comprising a number of vertical grooves is formed on the outer peripheral surface of the base portion of the elastic ring This is in addition to the fact that vertical ribs that engage with the knurling are provided on the inner peripheral surface of the outer cylinder of the outer cylinder.
[0015]
Since circumferential locking to the elastic ring is achieved by locking the vertical rib to the knurled, there is no need to consider alignment along the circumferential direction of the elastic ring when assembling the elastic ring. Since the vertical rib and the knurling are locked in the circumferential direction, there is no hindrance to fitting and mounting the elastic ring to the combination of the outer cylinder and the inner cylinder.
[0016]
The invention according to claim 3 is obtained by adding the upper end surface of the elastic ring to the invention according to claim 1 so as to be separated from the lower end surface of the mounting cylinder.
[0017]
By separating the upper end surface of the elastic ring from the lower end surface of the mounting cylinder, unnecessary force does not act on the elastic ring from the mounting cylinder, and proper elastic contact with the inner cylindrical body of the elastic ring can be maintained. In addition, the attachment of the mounting cylinder to the outer cylinder is not deteriorated by the elastic action of the elastic ring.
[0018]
The invention according to claim 4 is the invention according to claim 1, wherein the elastic ring is formed with the base portion thick and the action portion thin, and the outer circumference surface of the inner cylinder is substantially at the center of the inner circumference surface of the action portion. A sliding contact convex portion that elastically contacts with the projecting portion is provided in a projecting manner, and a hook portion is provided in a projecting manner at the upper end of the outer peripheral surface of the action portion.
[0019]
Since the base of the elastic ring is made thick, the fitting assembly between the screw cylinder and the outer cylinder can be achieved structurally and stably, and the formation of the locking function part in the circumferential direction is structurally achieved. In terms of space, it can be achieved with a margin.
[0020]
In addition, the action part of the elastic ring is made thin so that the action part can easily be elastically deformed, and the elastic deformation of the action part that is easily elastically deformed by the abutment of the collar part against the inner peripheral surface of the outer cylinder is doubly supported. Since the elastic contact portion with respect to the inner cylindrical body is specified as the sliding contact convex portion, it is easy to set the elastic contact strength of the elastic ring with respect to the inner cylindrical body and the frictional resistance force due to this elastic contact strength, Thereby, setting of a more appropriate feeling of resistance and more reliable prevention of rattling due to molding dimension error are achieved.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
The feeding container 1 is roughly composed of an outer cylindrical body 2, an inner cylindrical body 9, a tray body 20, and a cap body 22.
[0022]
The outer cylinder 2 includes a synthetic resin-made linear cylindrical screw cylinder 3 in which a screw groove 4 is formed on the inner peripheral surface, and a linear cylindrical outer cylinder 5 in which the screw cylinder 3 is fixedly inserted and fixed. A protruding peripheral portion 8 provided around the center portion of the outer peripheral surface is brought into contact with and fixed to the upper end inner peripheral surface of the outer cylindrical tube 5 at the upper end opening protruding above the screw tube 3 of the outer cylindrical tube 5. A cylindrical piece-like mounting cylinder 7 having a cylindrical piece portion above the peripheral portion 8 as a mounting function portion for the cap body 22 is configured.
[0023]
The inner cylinder 9 is provided with a pair of vertically long guide holes 12 over substantially the entire height range, and is installed in the screw cylinder 3. The guide cylinder portion 11 having a height substantially equal to the screw cylinder 3, and the guide cylinder portion 11 and a storage cylinder portion 10 having a diameter expanded continuously through a step portion 13, and the entirety thereof has a metal cylindrical shape.
[0024]
An elastic ring 14 made of a soft elastic material such as soft synthetic resin or rubber forms a thin working portion 17 on the upper portion of a relatively thick base portion 15. A sliding protrusion 18 which is a plurality of protrusions appropriately divided in the circumferential protrusion or circumferential direction of the book is provided, and a flange 19 is provided around the upper end of the outer peripheral surface.
[0025]
The elastic ring 14 is assembled to the outer cylinder 2 by fitting the base 15 between the upper end of the screw cylinder 3 of the outer cylinder 2 and the outer cylinder 5. A plurality of (four in the embodiment shown in FIG. 3) vertical ribs projecting on the inner peripheral surface of the outer cylinder 5 are engraved on the knurl 16 composed of a number of vertical grooves. By engaging 6 and locking from the circumferential direction, a circumferential locking function portion between the outer cylinder 2 and the elastic ring 14 is configured.
[0026]
In the assembled state of the elastic ring 14, the sliding contact projection 18 is elastically contacted with the outer peripheral surface of the storage cylinder portion 10 of the inner cylinder body 9 with a predetermined pressing force, and the outer peripheral surface of the flange portion 19 is the inner peripheral surface of the outer cylinder 5. Is slightly abutted against or slightly separated from the outer peripheral surface of the working portion 17 and the inner peripheral surface of the outer tube 5, and the upper end surface of the elastic ring 14 is below the mounting tube 7. Separated from the end face.
[0027]
The saucer body 20 is provided with a threaded projecting piece 21 that protrudes through the longitudinal guide hole 12 and is screwed into the threaded groove 4 on the outer peripheral surface, and has a diameter dimension that fits loosely and slidably into the inner cylindrical body 9. It is formed into a shape.
[0028]
The cap body 22 is formed in a top cylindrical shape in which the lower end opening is detachably fitted to the mounting cylinder 7 of the outer cylinder 2.
[0029]
【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be obtained.
Since the assembly of the elastic ring to the combination of the outer cylinder and the inner cylinder does not force the elastic ring to be elastically deformed in order to maintain this assembly, the assembled elastic ring is designed. It will be elastically contacted with the inner cylinder by the street force, so that it can be surely prevented from rattling and a moderate resistance feeling, and an appropriate and excellent operability will be exhibited.
[0030]
The assembly of the elastic ring to the combination of the outer cylindrical body and the inner cylindrical body is locked in the circumferential direction with respect to the outer cylindrical body so that the rotational displacement is impossible. Thus, the frictional contact is ensured, so that a frictional resistance can be reliably generated between the elastic ring and the inner cylindrical body, thereby improving the stability of the excellent operability.
[0031]
The mounting cylinder fitted to the upper end opening of the outer cylinder does not hold the assembled elastic ring but presses and displaces the elastic ring from the fitted part of the outer cylinder. Therefore, there is no possibility of deterioration of the fitted state with respect to the assembly of the elastic ring, so that a strong and stable assembly structure is maintained.
[0032]
The assembly of the elastic ring to the combination of the outer cylindrical body and the inner cylindrical body can be performed simply by fitting the elastic ring from one direction without forcibly elastically deforming the elastic ring in a certain form, and the assembly operation can be performed. It is very simple and high working efficiency can be obtained.
[0033]
According to the invention described in claim 2, since the locking function portion in the circumferential direction between the elastic ring and the outer cylindrical body is constituted by the knurls and vertical ribs configured by a number of vertical grooves, the locking function The direction in which the locking assembly of the part is aligned with the direction in which the elastic ring is fitted to the outer cylinder, and the elastic ring is assembled to the outer cylinder by a single handling operation of the elastic ring to the outer cylinder. And locking can be achieved, and excellent working efficiency can be obtained.
[0034]
According to the third aspect of the present invention, the mounting cylinder only prevents the elastic ring from coming out of the displacement by abutting, and in a steady state, the force that deteriorates the assembly of the mounting cylinder to the outer cylinder acts from the elastic ring at all. Therefore, the assembly structure can be held firmly and stably.
[0035]
According to the fourth aspect of the invention, the elastic ring can be stably fitted and assembled to the combination of the outer cylinder and the inner cylinder, and the elastic deformation of the action portion can be smoothly and stably maintained. Since the elastic contact portion with respect to the inner cylindrical body is specified as the sliding contact convex portion, the frictional resistance force between the elastic ring and the inner cylindrical body can be set accurately and easily. In addition, it is possible to reliably and satisfactorily prevent the occurrence of rattling due to molding dimension errors.
