Description

【0001】
【発明の属する技術分野】
本発明は、口紅、アイシャドウ等の棒状化粧料を収納し、回転繰り出し機構を内装した棒状化粧料繰り出し容器に関し、量産性を向上させた棒状化粧料繰り出し容器に関するものである。
【0002】
【従来の技術】
従来より、特開平8−19442号公報において、棒状化粧料を収容、保持し、下端部に突起を突設した中皿体と、この中皿体を上下摺動自在に内装し、下部に前記中皿体の突起が貫通して中皿体を回転不能に案内する摺動孔を長手方向に穿設した本体と、この本体下部が挿入され、内壁に前記中皿体の突起が螺合する螺旋溝を螺設した外筒体と、を具備し、上記本体の外周面に鍔状の嵌合部を周設し、外筒体先端に中具を止着することによって、本体の嵌合部を外筒体と中具の間に挟持させ、本体を回転自在に脱落不能に連結させた棒状化粧料容器が提案されている。この種の構成は、外筒体内壁に螺旋溝を螺設してあるため、螺旋溝を螺設した螺旋筒を1パーツ少なくすることができ、部品コストを削減できた。更に、部品が1パーツ減少した点に加え、中具を本体筒に止着するだけで棒状化粧料容器を構成する全ての部品を脱落不能に連結させることができるため、組立の省力化がはかれた。等、量産性を向上させる利点を数多く有していた。
【0003】
【発明が解決しようとする課題】
しかし、棒状化粧料容器は筒体の組み合わせであり、金属同士の擦れ合いは、極端に操作感が劣化するため、操作感が重視される棒状化粧料容器には、あまり採用されていなかった。従って、上記構成は本体が金属薄板より成形されているため、これに擦れ合う外筒体及び中具は合成樹脂により成型する必要があった。この外筒体及び中具は、外部に露出する外装体であるため、加飾を施す必要があった。この合成樹脂の加飾と、金属の加飾を比較すると、どうしても高級感、質感で金属の加飾に比べて劣ってしまい、高級な棒状化粧料容器に採用されない欠点を有していた。
【0004】
更に、本体が薄肉金属筒体より成形されているため、本体を成形するためには、パイプの先端を先端形状に合わせて切断する切断工程、本体側面に鍔状の嵌合部を成形する成形工程、本体側面に摺動孔を穿設する穿設工程、その後、仕上げ工程としてバリ取り工程、面取り工程等、数多くの工程が必要となっていた。
【0005】
【課題を解決するための手段】
棒状化粧料1を収嵌保持し、下端に脚筒39を垂下し、該脚筒39の下部側壁に螺合突部3を突設した保持筒2と、該保持筒2を上下摺動自在に内装し、側壁に前記螺合突部3が貫通して保持筒2を回動不能に案内するガイド溝5が穿設され、外周に鍔部26を突設したスリーブ13と、該スリーブ13の下部が回動自在に挿入され、内壁に前記螺合突部3が螺合する螺旋溝29を螺設し、該螺旋溝29上端に段部10を構成した本体筒14と、該本体筒14の上端に止着され、下端に前記スリーブ13の鍔部26が当接して、前記本体筒14の段部10との間に鍔部26を挟持し、スリーブ13を回動自在に脱落不能に保持し、上部にキャップ16が抜脱可能に嵌合する嵌合部30を設けた嵌合筒15と、よりなり、前記スリーブ13を上部スリーブ13aと下部スリーブ13bに分割し、該上部スリーブ13aの下端に窓部34を1個所以上穿設し、下部スリーブ13bの上端に上部スリーブ13a下端が挿入される連結部43を設け、該連結部43内壁に上部スリーブ13aの窓部34と係合して上部スリーブ13aと下部スリーブ13bを一体に連結する連結突部20を突設し、連結部43外径が大径に拡大することにより、外壁に鍔部26を構成してなる棒状化粧料繰り出し容器。
【0006】
【作用】
スリーブ13を保持して本体筒14を回転操作すると、スリーブ13のガイド溝5を貫通した螺合突部3が、回転する本体筒14内壁に螺設された螺旋溝29と螺合しているため、螺合作用により保持筒2が上下動して棒状化粧料1が繰り出される。この時、下部スリーブ13bが合成樹脂より成形されているため、スリーブ13の鍔部26を挟持する本体筒14及び嵌合筒15と擦れ合っているが、金属同士の擦れ合いとなることはない。
【0007】
【発明の実施の形態】
棒状化粧料1を収嵌保持する保持筒2は、上下端に開口した貫通穴41が穿設されている。この貫通穴41の上部内壁には、仕切り部44が設けられ、上部が棒状化粧料1を収嵌保持する保持部45となり、下部が脚筒39となっている。その結果、この保持筒2は、予め成形した棒状化粧料1を保持させることも、脚筒39側から化粧料を充填して棒状化粧料1を成形することも可能になっている。この脚筒39の下部外側壁には、一対の螺合突部3が突出している。
【0008】
この保持筒2は、スリーブ13内に上下摺動自在に内装されている。このスリーブ13は、上部スリーブ13aと下部スリーブ13bとより成っている。この上部スリーブ13aは、銅合金、アルミ合金等の薄肉金属より成形されており、上端が棒状化粧料1の出没穴23となっている。また、上部スリーブ13aの下端側壁には、窓部34が1個所以上穿設されている。
【0009】
下部スリーブ13bは、合成樹脂より成形されており、上端には上部スリーブ13aの下端が挿入される連結部43となっている。この連結部43の内壁には、上部スリーブ13aの窓部34に係合して上部スリーブ13aと下部スリーブ13bを脱落不能に連結する連結突部20が突出している。また、連結部43の部位は、下方よりも外径が拡大して、鍔部26を構成している。この鍔部26の下方側壁には、前記保持筒2の螺合突部3が貫通し、保持筒2をスリーブ13内で回動不能に上下摺動自在に案内するガイド溝5が軸線と平行に穿設されている。このガイド溝5の下端は、下部スリーブ13bの下端に開溝しており、螺合突部3が下方から侵入可能となっている。その結果、保持筒2がスリーブ13の下方より組み付け可能となっている。また、下部スリーブ13b下端のガイド溝5が刻設されていない部位には、一対の切り欠き31が水平方向に長く穿設され、切り欠き31下方の下部スリーブ13b下端に弾性部36を構成している。この弾性部36のほぼ中央には、下方に突出した摺接突部35が設けられている。
【0010】
なお、このスリーブ13は、それぞれに成形した上部スリーブ13aと下部スリーブ13bを組み付けて構成することも可能であるが、加飾が施された上部スリーブ13aをインサートして下部スリーブ13bを成形することによって構成することも可能になっている。また、保持筒2の上端は、保持筒2が下死点のとき、上部スリーブ13aの窓部34よりも上方に位置させる必要がある。
【0011】
このスリーブ13の下部、つまり下部スリーブ13bは、本体筒14内に回動可能に挿入されている。この本体筒14の下面には、挿入穴28が穿設され、スリーブ13内に収納された保持筒2内に充填ノズルが侵入し、保持筒2内に化粧料が充填可能となっている。なお、この挿入穴28は、予め成形した棒状化粧料1を保持筒2に保持させるタイプの場合には、穿設する必要がない。また、本体筒14内壁の、前記下部スリーブ13bのガイド溝5と相対する部位には、内壁全周に細かい無数条の凸凹を有したローレットを螺旋状に螺設した螺旋状ローレット24が螺設されている。また、前記保持筒2の螺合突部3の先端面に、隣り合った複数条の螺旋状ローレット24と螺合する細かい凸凹を有した螺合面25を刻設している。なお、この構成の場合、螺合突部3の数と螺旋状ローレット24の条数とは一致していないが、従来よりある、螺合突部3の数と螺旋条の条数が一致した螺旋溝29を螺設可能であることは言うまでもない。この螺旋状ローレット24上部内壁は、内径が拡大した止着部47となっており、螺旋状ローレット24上端に段部10を構成している。この段部10は、本体筒14にスリーブ13を組み付けたとき、スリーブ13の鍔部26下端が当接するようになっている。この時、下部スリーブ13bの下端の摺接突部35は、本体筒14底面の挿入穴28周縁部に弾性を有して当接するようになっている。
【0012】
この本体筒14の止着部47には、嵌合筒15が挿入止着されている。この嵌合筒15の上部は、本体筒14上端よりも突出して、キャップ16が抜脱可能に嵌合する嵌合部30となっている。そして、上部スリーブ13aは、嵌合筒15の嵌合部30よりも更に上方に突出して外部に露出している。また、嵌合筒15の下端には、前記下部スリーブ13bの鍔部26上端に当接して、スリーブ13鍔部26を本体筒14の段部10との間に挟持してスリーブ13を回動可能に脱落不能に保持する当接部12を設けている。この時、下部スリーブ13bの摺接突部35は、本体筒14底面に弾性を有して当接し、スリーブ13を保持して本体筒14を回転操作した際、摺動抵抗を発生させ、操作感を良好なものにしている。
【0013】
【発明の効果】
本発明は以上のように、本来金属より成形されていたスリーブ13の、他の部分と擦れ合う部分を、合成樹脂で成形し、外部に露出する部分を金属で成形し、それぞれを脱落不能に連結させているため、金属同士の擦れ合いは全く起こらない。従って、外部に露出する嵌合筒15と本体筒14を、高級感のある金属で成形することも、成形性に優れた合成樹脂で成形することも可能となり、極めて汎用性の高いスリーブ13を提供できる。しかも、上部スリーブ13aと下部スリーブ13bをインサート成形してスリーブ13を構成しているため、金属より成形される上部スリーブ13aの仕上げ加工工程を省くことが可能になり、製造コストを低下させ、量産性を向上させている。また、外部に露出する上部スリーブ13の先端形状の変更は、下部スリーブ13bの金型はそのままに、金型コストの安価な上部スリーブ13aの切断工程の変更で対処できるため、スリーブ13先端形状のデザイン変更には、安価に柔軟に対処できるようになっている。
【0014】
更に本発明は、保持筒2の螺合突部3が本体筒14内壁に螺設された隣り合った複数条の螺旋状ローレット24と螺合しているため、螺旋条1本にかかる負荷を分散することができ、螺合突部3と螺旋状ローレット24の引っ掛かりの量、つまり螺旋状ローレット24の溝深さを浅くすることができる。そして、溝深さが浅くなると、本体筒14の肉厚を薄くすることができ、本体筒14を金属で、プレス加工によって成形できる。また、合成樹脂で成形する場合も、溝の浅い無数条の螺旋状ローレット24が内壁全周に設けられているため、成形時の肉厚の差による収縮量の差が僅かなものとなり、本体筒14外壁に現れるその影響をほとんど判別が付かない程度にしている。従って、本体筒14を成形したままで、表面処理、加飾工程を必要とせず、商品として使用することもできる。
【0015】
加えて、保持筒2の螺合突部3が本体筒14内壁に螺設された隣り合った複数条の螺旋状ローレット24と螺合しているため、螺合のがたつきを全くと言っていいほどなくせる。従って、棒状化粧料容器に衝撃等が加わったとしても、棒状化粧料1が振れて容器内壁に当たってしまい棒状化粧料1を損傷してしまうような事は全く起こらない。更に、棒状化粧料1の回転繰り出し操作時にも、余計な遊びが全くなく、ダイレクトに操作している感触が手に伝わり、繰り出し操作感を良好なものにしている。加えて、保持筒2の上死点若しくは下死点で、螺合突部3に負荷がかかって、螺合面25が螺旋状ローレット24から外れてしまったとしても、すぐとなりの螺旋状ローレット24に螺合するため、繰り出し機構が破損して使用不能になってしまったり、使用者に不快感を与えてしまったりするようなことはない。更に保持筒2の螺合突部3を本体筒14の螺旋状ローレット24に螺合させる際には、螺旋状ローレット24が本体筒14内壁全周に螺設されているため、どの位置からでも螺合させることができ、位置あわせして螺合させるような組立の手間を省くことができ、組立の自動化にも対応できる。
【0016】
また、下部スリーブ13bの下方に弾性を有した摺接突部35を突設して、スリーブ13を上方に弾発しているため、スリーブ13、本体筒14、嵌合筒15の寸法の誤差より発生するがたつきを吸収できる。また、回転繰り出し操作時には、摺接突部35が相対回転する本体筒14底面に弾性を有して当接しているため、摺動抵抗が発生し、繰り出し操作感を高級感のあるものにしている。

[0002]
[Prior art]
Conventionally, in Japanese Patent Application Laid- Open No. 8-19442, an inner dish body that contains and holds a bar-shaped cosmetic and has a protrusion projecting at the lower end thereof, and the inner dish body is slidably mounted vertically, A main body having a longitudinally extending sliding hole through which the protrusion of the inner tray body penetrates and guides the inner tray body in a non-rotatable manner, and the lower portion of the main body are inserted, and the protrusion of the inner tray body is screwed into the inner wall. An outer cylinder having a spiral groove formed therein, a flange-like fitting portion is provided around the outer peripheral surface of the main body, and the inner fitting is fixed to the distal end of the outer cylinder, thereby fitting the main body A bar-shaped cosmetic container has been proposed in which a portion is sandwiched between an outer cylinder and an inner tool and a main body is rotatably connected so as not to fall off. In this type of configuration, since the spiral groove is screwed on the wall of the outer cylinder, one part of the spiral cylinder having the spiral groove can be reduced, and the part cost can be reduced. Furthermore, in addition to the fact that the number of parts has been reduced by 1 part, all the parts that make up the stick-shaped cosmetic container can be connected so as not to fall off by simply fixing the inner parts to the main body cylinder. It was. Etc., and had many advantages for improving mass productivity.
[0003]
[Problems to be solved by the invention]
However, the stick-shaped cosmetic container is a combination of cylinders, and rubbing between metals is extremely poor in operation feeling, so that it has not been widely used in bar-shaped cosmetic containers where the feeling of operation is important. Therefore, since the main body is molded from a thin metal plate in the above configuration, the outer cylinder and the inner tool that rub against each other need to be molded from a synthetic resin. Since the outer cylinder and the inner tool are exterior bodies exposed to the outside, it is necessary to decorate them. When this synthetic resin decoration was compared with metal decoration, it was inevitably inferior to metal decoration due to its high-quality feeling and texture, and had the disadvantage that it was not used in high-grade bar-shaped cosmetic containers.
[0004]
Furthermore, since the main body is molded from a thin metal cylinder, in order to mold the main body, a cutting process in which the tip of the pipe is cut in accordance with the tip shape, and a hook-shaped fitting portion is molded on the side of the main body. Numerous processes such as a process, a drilling process for drilling a sliding hole on the side surface of the main body, and then a deburring process and a chamfering process as finishing processes have been required.
[0005]
[Means for Solving the Problems]
The rod-shaped cosmetic 1 is fitted and held, a leg tube 39 is suspended at the lower end, a holding cylinder 2 having a threaded projection 3 protruding from the lower side wall of the leg cylinder 39, and the holding cylinder 2 can be slid up and down. The sleeve 13 is provided with a guide groove 5 that penetrates the side wall of the screw projection 3 and guides the holding cylinder 2 in a non-rotatable manner. A main body cylinder 14 in which a spiral groove 29 into which the screwing protrusion 3 is screwed is screwed on the inner wall, and a step 10 is formed at the upper end of the spiral groove 29, and the main body cylinder 14 is fastened to the upper end of the sleeve 14, and the flange portion 26 of the sleeve 13 is in contact with the lower end of the sleeve 14. And a fitting tube 15 provided with a fitting portion 30 in which the cap 16 is detachably fitted to the upper portion, and the sleeve 13 is The upper sleeve 13a is divided into a sleeve 13a and a lower sleeve 13b. One or more windows 34 are formed in the lower end of the upper sleeve 13a, and a connecting portion 43 into which the lower end of the upper sleeve 13a is inserted is provided at the upper end of the lower sleeve 13b. A connecting projection 20 is provided on the inner wall of the portion 43 so as to engage with the window 34 of the upper sleeve 13a and integrally connect the upper sleeve 13a and the lower sleeve 13b, and the outer diameter of the connecting portion 43 is increased to a large diameter. A stick-shaped cosmetic material delivery container comprising a collar portion 26 on the outer wall.
[0006]
[Action]
When the main body cylinder 14 is rotated while holding the sleeve 13, the screwing protrusion 3 that penetrates the guide groove 5 of the sleeve 13 is screwed into a spiral groove 29 that is screwed on the inner wall of the rotating main body cylinder 14. Therefore, the holding cylinder 2 moves up and down by the screwing action, and the bar-shaped cosmetic 1 is fed out. At this time, since the lower sleeve 13b is formed of a synthetic resin, the lower sleeve 13b rubs against the main body cylinder 14 and the fitting cylinder 15 that sandwich the flange portion 26 of the sleeve 13, but the metal does not rub against each other. .
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The holding cylinder 2 that fits and holds the bar-shaped cosmetic material 1 is provided with a through hole 41 that is open at the upper and lower ends. A partition portion 44 is provided on the upper inner wall of the through hole 41, the upper portion serves as a holding portion 45 that fits and holds the bar-shaped cosmetic 1, and the lower portion serves as a leg tube 39. As a result, the holding cylinder 2 can hold the preformed stick-shaped cosmetic 1 or can fill the cosmetic from the leg tube 39 side to form the stick-shaped cosmetic 1. A pair of screw projections 3 protrude from the lower outer wall of the leg tube 39.
[0008]
The holding cylinder 2 is housed in a sleeve 13 so as to be slidable up and down. The sleeve 13 includes an upper sleeve 13a and a lower sleeve 13b. The upper sleeve 13 a is formed from a thin metal such as a copper alloy or an aluminum alloy, and has an upper and lower hole 23 for the bar-shaped cosmetic 1. Further, at least one window 34 is formed in the lower end side wall of the upper sleeve 13a.
[0009]
The lower sleeve 13b is formed of synthetic resin, and has a connecting portion 43 into which the lower end of the upper sleeve 13a is inserted at the upper end. On the inner wall of the connecting portion 43, a connecting projection 20 that engages with the window portion 34 of the upper sleeve 13 a and connects the upper sleeve 13 a and the lower sleeve 13 b so as not to fall off protrudes. Moreover, the outer diameter of the part of the connecting portion 43 is larger than that of the lower portion and constitutes the flange portion 26. A threaded projection 3 of the holding cylinder 2 passes through a lower side wall of the flange 26, and a guide groove 5 that guides the holding cylinder 2 so as not to rotate within the sleeve 13 so as to be slidable up and down is parallel to the axis. Has been drilled. The lower end of the guide groove 5 is open at the lower end of the lower sleeve 13b, so that the screwing protrusion 3 can enter from below. As a result, the holding cylinder 2 can be assembled from below the sleeve 13. Further, a pair of notches 31 are formed in the horizontal direction in a portion where the guide groove 5 at the lower end of the lower sleeve 13b is not engraved, and an elastic portion 36 is formed at the lower end of the lower sleeve 13b below the notch 31. ing. Near the center of the elastic portion 36, a sliding contact projection 35 protruding downward is provided.
[0010]
The sleeve 13 can be formed by assembling an upper sleeve 13a and a lower sleeve 13b that are molded respectively, but the lower sleeve 13b is formed by inserting the decorated upper sleeve 13a. It is also possible to configure by. Further, the upper end of the holding cylinder 2 needs to be positioned above the window 34 of the upper sleeve 13a when the holding cylinder 2 is at the bottom dead center.
[0011]
A lower portion of the sleeve 13, that is, a lower sleeve 13 b is rotatably inserted into the main body cylinder 14. An insertion hole 28 is formed in the lower surface of the main body cylinder 14 so that a filling nozzle enters the holding cylinder 2 accommodated in the sleeve 13 so that cosmetics can be filled into the holding cylinder 2. The insertion hole 28 does not need to be drilled in the case of a type in which the bar-shaped cosmetic 1 molded in advance is held by the holding cylinder 2. Further, a spiral knurl 24 in which a knurl having an infinite number of fine irregularities is spirally screwed around the entire inner wall is screwed at a portion of the inner wall of the main body cylinder 14 facing the guide groove 5 of the lower sleeve 13b. Has been. In addition, a threaded surface 25 having fine irregularities that are threadedly engaged with a plurality of adjacent spiral knurls 24 is formed on the front end surface of the threaded projection 3 of the holding cylinder 2. In this configuration, the number of screw projections 3 and the number of spiral knurls 24 do not match, but the conventional number of screw projections 3 and the number of spiral stripes match. Needless to say, the spiral groove 29 can be screwed. The upper inner wall of the spiral knurl 24 is a fastening portion 47 having an enlarged inner diameter, and forms a step portion 10 at the upper end of the spiral knurl 24. The step portion 10 is configured such that when the sleeve 13 is assembled to the main body cylinder 14, the lower end of the flange portion 26 of the sleeve 13 abuts. At this time, the slidable contact projection 35 at the lower end of the lower sleeve 13b comes into contact with the peripheral edge of the insertion hole 28 on the bottom surface of the main body cylinder 14 with elasticity.
[0012]
The fitting cylinder 15 is inserted and fixed to the fixing portion 47 of the main body cylinder 14. The upper portion of the fitting cylinder 15 protrudes from the upper end of the main body cylinder 14 and serves as a fitting portion 30 into which the cap 16 is detachably fitted. The upper sleeve 13a protrudes further upward than the fitting portion 30 of the fitting cylinder 15 and is exposed to the outside. Further, the lower end of the fitting cylinder 15 is in contact with the upper end of the flange portion 26 of the lower sleeve 13b, and the sleeve 13 is rotated between the sleeve 13 flange portion 26 and the step portion 10 of the main body cylinder 14. An abutting portion 12 is provided for holding it so as not to fall off. At this time, the sliding contact projection 35 of the lower sleeve 13b abuts the bottom surface of the main body cylinder 14 with elasticity, and when the main body cylinder 14 is rotated while holding the sleeve 13, the sliding resistance is generated. The feeling is good.
[0013]
【The invention's effect】
As described above, according to the present invention, the portion of the sleeve 13 originally molded from metal is molded with a synthetic resin, and the portion exposed to the outside is molded with metal, and each of them is connected so that it cannot be dropped off. As a result, there is no friction between the metals. Therefore, the fitting cylinder 15 and the main body cylinder 14 exposed to the outside can be molded with a high-grade metal, or can be molded with a synthetic resin excellent in moldability, and the highly versatile sleeve 13 can be formed. Can be provided. In addition, since the upper sleeve 13a and the lower sleeve 13b are insert-molded to form the sleeve 13, the finishing process of the upper sleeve 13a formed from metal can be omitted, the manufacturing cost can be reduced, and mass production can be performed. Improves sex. Further, the change of the tip shape of the upper sleeve 13 exposed to the outside can be dealt with by changing the cutting process of the upper sleeve 13a at a low cost while keeping the mold of the lower sleeve 13b as it is. Design changes can be handled flexibly at low cost.
[0014]
Further, in the present invention, since the screw projection 3 of the holding cylinder 2 is screwed with a plurality of adjacent spiral knurls 24 screwed on the inner wall of the main body cylinder 14, the load applied to one spiral stripe is reduced. It is possible to disperse, and the amount of catching between the screw projection 3 and the spiral knurl 24, that is, the groove depth of the spiral knurl 24 can be reduced. When the groove depth is reduced, the thickness of the main body cylinder 14 can be reduced, and the main body cylinder 14 can be formed of metal by press working. In addition, even when molding with synthetic resin, because the spiral knurls 24 with shallow grooves are provided on the entire inner wall, the difference in shrinkage due to the difference in wall thickness during molding becomes slight, The influence appearing on the outer wall of the cylinder 14 is set so as to be hardly discriminated. Therefore, the main body cylinder 14 can be used as a product without forming the surface treatment and the decorating process while the main body cylinder 14 is molded.
[0015]
In addition, since the screw projection 3 of the holding cylinder 2 is screwed with the adjacent spiral knurls 24 screwed on the inner wall of the main body cylinder 14, the rattling of the screw is completely avoided. It can be lost. Therefore, even if an impact or the like is applied to the stick-shaped cosmetic container, the stick-shaped cosmetic 1 does not shake at all and hits the inner wall of the container and damages the stick-shaped cosmetic 1 at all. Furthermore, there is no extra play at the time of the rotational feeding operation of the bar-shaped cosmetic 1, and the feeling of direct operation is transmitted to the hand, so that the feeding operation feeling is improved. In addition, even if a load is applied to the screwing projection 3 at the top dead center or the bottom dead center of the holding cylinder 2 and the screwing surface 25 is detached from the spiral knurling 24, the immediate spiral knurling is performed. Since it is screwed to 24, the feeding mechanism is not damaged and cannot be used, or the user is uncomfortable. Further, when the threaded projection 3 of the holding cylinder 2 is screwed into the spiral knurl 24 of the main body cylinder 14, the spiral knurl 24 is screwed around the inner wall of the main body cylinder 14. It can be screwed together, and it is possible to save the trouble of assembling such as positioning and screwing, and it can cope with automation of assembling.

Further, since a sliding contact projection 35 having elasticity is provided below the lower sleeve 13b to project the sleeve 13 upward, an error in the dimensions of the sleeve 13, the main body cylinder 14, and the fitting cylinder 15 is caused. The generated rattling can be absorbed. Further, at the time of the rotation feeding operation, since the sliding contact projection 35 is elastically in contact with the bottom surface of the main body cylinder 14 which is relatively rotated, sliding resistance is generated, and the feeding operation feeling is made to have a high-class feeling. Yes.
