Description

本発明は、通信ケーブル等接続部用気密性収納容器及びガスケットに関する。更に詳しくは、設置環境に影響されることなく確実に気密性を保持することが可能であるとともに、組み立て時における作業性を向上させた通信ケーブル等接続部用気密性収納容器及びそれに用いられるガスケットに関する。   The present invention relates to an airtight container for a connection portion such as a communication cable and a gasket. More specifically, an airtight storage container for a connection portion such as a communication cable, which can reliably maintain airtightness without being affected by the installation environment and has improved workability during assembly, and a gasket used therefor About.

従来から、通信ケーブルの接続部分を気密状態で収納するため、中空容器を上下二つに分割した形状を有する上下容器（例えば、通信ケーブルの接続の場合における上下スリーブ）を接続して組み立てる際、その分割面に形成した溝にガスケットを介在させることによって気密性を確保する通信ケーブル等の接続部用気密性収納容器が用いられている（例えば、特許文献１〜３参照）。   Conventionally, in order to store the connection portion of the communication cable in an airtight state, when connecting and assembling an upper and lower container (for example, an upper and lower sleeve in the case of connection of a communication cable) having a shape obtained by dividing the hollow container into upper and lower parts, An airtight storage container for a connection portion such as a communication cable that secures airtightness by interposing a gasket in a groove formed in the divided surface is used (see, for example, Patent Documents 1 to 3).

図４に示すように、通信ケーブル等接続部用気密性収納容器１０は、中空の容器を上下に分割した形状で、それぞれの分割面に互いに対向する上下対称の溝３１、３２を備えた上下スリーブ１１、１２と、溝３１、３２の中に装着されるガスケット２１とから構成され、内部に通信用ケーブル４１を接続、収納した後、下スリーブ１２側の溝３２の中にガスケット２１を装着した状態で、上下スリーブ１１、１２をボルトによって締め付けることによって、内部に気密空間を形成する構成からなっている。なお、図４において、通信用ケーブル４１は、端面板３３によって支持されるとともに、閉塞栓３４によって密閉される。また、端面板３３の外周には粘着シール材３５が設けられるとともに、ガスケット２１の両端に粘着シール材（図示せず）が設けられ、上下スリーブ１１、１２の接続時の密封性を向上させている。ここで、気密性収納容器１０の気密性は、上下スリーブ１１、１２に上下から押圧されて装着されるガスケット２１の上下面と、溝３２の底面との間の面圧で気密空間を実現することによって達成される。
実開平２−３３５３２号公報 実開平２−３３５３０号公報 特開２０００−１７０９１７号公報 As shown in FIG. 4, the airtight storage container 10 for a connection portion such as a communication cable has a shape in which a hollow container is divided into upper and lower parts and is provided with upper and lower symmetrical grooves 31 and 32 facing each other on the respective divided surfaces. It is composed of sleeves 11 and 12 and a gasket 21 mounted in the grooves 31 and 32. After the communication cable 41 is connected and housed inside, the gasket 21 is mounted in the groove 32 on the lower sleeve 12 side. In this state, the upper and lower sleeves 11 and 12 are tightened with bolts to form an airtight space inside. In FIG. 4, the communication cable 41 is supported by the end face plate 33 and sealed by the closing plug 34. In addition, an adhesive seal material 35 is provided on the outer periphery of the end face plate 33, and an adhesive seal material (not shown) is provided on both ends of the gasket 21, thereby improving the sealing performance when the upper and lower sleeves 11 and 12 are connected. Yes. Here, the airtightness of the airtight storage container 10 realizes an airtight space by a surface pressure between the upper and lower surfaces of the gasket 21 which is pressed and attached to the upper and lower sleeves 11 and 12 and the bottom surface of the groove 32. Is achieved.

図５（ａ）に示すように、上下スリーブ１１、１２に上下から押圧されて装着されるガスケット２１の形状は、その長手方向に垂直な断面の幅Ｗ２１（断面の任意の位置における幅）が下スリーブ１２側の溝３２の側壁間の幅Ｗ３２（Ｗ２１と同じ位置における幅）よりも小であるため、ガスケット２１は溝３２の中で動きの自由度が大であり、図５（ｂ）に示すように、下スリーブ１２側の溝３２に装着された場合に、溝３２の中で左右のいずれか側に倒れた状態で上方から上スリーブ１１を押圧すると、上下スリーブ１１、１２側の溝３１、３２の中の所望の位置に装着されることなく、上下スリーブ１１、１２における溝３１、３２からはみ出した状態で挟持される場合があり、上下スリーブ１１、１２間に隙間を生じさせ、気密性を維持できない場合があった。   As shown in FIG. 5A, the shape of the gasket 21 that is pressed and attached to the upper and lower sleeves 11 and 12 from the upper and lower sides is such that the width W21 of the cross section perpendicular to the longitudinal direction (the width at an arbitrary position of the cross section). Since the width is smaller than the width W32 between the side walls of the groove 32 on the lower sleeve 12 side (the width at the same position as W21), the gasket 21 has a large degree of freedom of movement in the groove 32, and FIG. As shown in FIG. 3, when the upper sleeve 11 is pressed from above with the groove 32 on the lower sleeve 12 side being tilted to the left or right side in the groove 32, In some cases, the upper and lower sleeves 11 and 12 may be sandwiched in a state of protruding from the grooves 31 and 32 without being mounted at desired positions in the grooves 31 and 32, and a gap is generated between the upper and lower sleeves 11 and 12. Airtight There is a case that can not be equity.

特許文献１及び特許文献２によれば、ガスケットの断面形状を楕円にしたり突起を設けた上下対称の形状のものが開示されている。しかし、前述した図５（ａ）のように溝の側壁間の幅がガスケットの前記断面の幅よりも広くなると、ガスケットが溝の中での動きの自由度が大になってしまい上記問題を解決できない。また、特許文献３のクロージャのパッキン取り付け用溝部に装着するパッキンはここでいうガスケットに相当するが、パッキンの断面形状が前述した図５（ａ）のように楕円の場合、ガスケットが溝の中での動きの自由度が大になってしまい上記問題を解決できない。   According to Patent Document 1 and Patent Document 2, a vertically symmetric shape in which the gasket has an elliptical cross-sectional shape or a protrusion is disclosed. However, if the width between the side walls of the groove is wider than the width of the cross section of the gasket as shown in FIG. 5 (a), the degree of freedom of movement of the gasket in the groove increases. It cannot be solved. In addition, the packing attached to the packing mounting groove portion of the closure of Patent Document 3 corresponds to the gasket here, but when the cross-sectional shape of the packing is an ellipse as shown in FIG. 5A, the gasket is in the groove. The above-mentioned problem cannot be solved because the degree of freedom of movement increases.

この問題は、気密性収納容器の設置場所が、架空など良い作業条件が得られにくい場合、上下スリーブの溝にガスケットを装着する際、ガスケットが適性に装着されたか否かガスケットの収まりの確認が困難であった。十分な確認をしないと、ガスケットが溝からはみ出して気密性を維持できない場合がある。   This problem is that when the installation location of the airtight storage container is difficult to obtain, such as aerial, it is difficult to confirm whether the gasket is properly fitted when installing the gasket in the groove of the upper and lower sleeves. It was difficult. If sufficient confirmation is not made, the gasket may protrude from the groove and may not maintain airtightness.

また、設置場所が、通信ケーブルを収納するための埋設したコンクリート溝の上で、ケーブルの接続と気密性収納容器の組み立てを行う場合、ケーブルが数１００ｍ程度と長い場合、地上の高い位置に持ち上げて作業をすることが困難であった。ケーブルを無理に持ち上げると、接続し組み立てた気密性収納容器を元に収納することができなくなる場合がある。従って、ケーブルの接続と気密性収納容器の組み立ては、地上からわずかに上の低い位置で行わざるを得ないことになり、ガスケットの収まりを十分確認することが困難であった。   Also, when installing the cable on a buried concrete groove for storing communication cables and assembling an airtight storage container, if the cable is as long as several hundred meters, lift it to a high position on the ground. It was difficult to work. If the cable is forcibly lifted, it may not be possible to store it based on the sealed and assembled container. Therefore, the connection of the cable and the assembly of the airtight storage container must be performed at a low position slightly above the ground, and it is difficult to sufficiently check the fit of the gasket.

また、気密性収納容器やガスケットの材料は、耐久性を向上させるためにカーボンを含有させてあり、外観が黒色であるため、夜間においては気密性収納容器やガスケットのコントラストが不鮮明となる場合もあり、上下スリーブ締結時のガスケットの収まりを確認することが困難であった。   In addition, since the material of the airtight storage container and gasket contains carbon to improve durability and the appearance is black, the contrast of the airtight storage container and gasket may be unclear at night. It was difficult to confirm the fit of the gasket when the upper and lower sleeves were fastened.

上述のような作業環境や設置環境によってガスケットの収まりを確認することの困難さを更に増大させている。このように、気密性収納容器のガスケットの溝からのはみ出しは気密性収納容器の気密性を損なう大きな要因となる。   The difficulty of confirming the fit of the gasket is further increased by the working environment and the installation environment as described above. Thus, the protrusion of the gastight storage container from the groove of the gasket is a major factor that impairs the airtightness of the gastight storage container.

本発明は、上述の問題に鑑みなされたもので、設置環境に影響されることなく確実に気密性を保持することが可能であるとともに、組み立て時における作業性を向上させた通信ケーブル等接続部用気密性収納容器及びそれに用いられるガスケットを提供することを目的とする。   The present invention has been made in view of the above-mentioned problems, and it is possible to reliably maintain airtightness without being affected by the installation environment, and a connection portion such as a communication cable that has improved workability during assembly. An object of the present invention is to provide an airtight storage container and a gasket used therefor.

That is, this invention provides the following airtight storage containers for connection parts, such as a communication cable, and the gasket used therefor.

以下、本発明の実施の形態を、図面を参照しつつ具体的に説明する。   Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

図１は本発明の気密性収納容器及びガスケットの実施形態を示す説明図である。   FIG. 1 is an explanatory view showing an embodiment of an airtight container and gasket according to the present invention.

図１に示す本発明の気密性収納容器１０は、円筒状の中空の容器であり、その中空の容器は、円筒状の中空の容器を円筒の回転軸を含む平面で２分割した上側を構成する上容器（上スリーブ）１１と、下側を構成する下容器（下スリーブ）１２とからなっている。上下スリーブ１１、１２の材質は、軽量で耐久性に優れ、強度に優れたプラスチックであることが好ましい。より好ましくは、ガラス繊維を補強材とした熱硬化性樹脂（主として不飽和ポリエステル樹脂やエポキシ樹脂）で、ＦＲＰ（ガラス繊維強化プラスチック）と呼ばれるものであるが、収納する電線ケーブルと同等以上の耐用年数をもたせるため、最も好ましくはＦＲＰＰ（ガラス繊維強化ポリプロピレン）である。耐久性を高めるためにＦＲＰＰはカーボンを含有してもよい。上下スリーブは一般に射出成形、プレス成形等によって形成される。下スリーブ１２の長手方向両端部より通信用ケーブルが、端面板３３及び粘着シール材により気密性が保持されるようにして挿入され、気密性収納容器１０の内部に通信用ケーブル４１の端部が収納されるように形成されている。上スリーブ１１と下スリーブ１２のそれぞれの分割面３６には、分割面の長手方向に沿ってそれぞれ互いに対向する上下対称の溝３１、３２が形成されている。そして溝３２に沿ってガスケット２１が装着され、上スリーブ１１と下スリーブ１２とを分割面３６で接合し、締付具３７により固定することにより、円筒状の気密性収納容器１０を形成する際に、ガスケット２１により接合部分の気密性が確保される。ここで、気密性は、ガスケット２１が、上スリーブ１１の溝３１及び下スリーブ１２の溝３２の底部に押圧され、その接する面の面圧により確保されている。図１に示す気密性収納容器１０は、ケーブルの端部同士を気密に接続するために使用する気密性クロージャを形成している。   An airtight storage container 10 of the present invention shown in FIG. 1 is a cylindrical hollow container, and the hollow container constitutes an upper side obtained by dividing the cylindrical hollow container into two parts by a plane including a cylindrical rotation axis. An upper container (upper sleeve) 11 and a lower container (lower sleeve) 12 constituting the lower side. The material of the upper and lower sleeves 11 and 12 is preferably a plastic that is lightweight, excellent in durability, and excellent in strength. More preferably, it is a thermosetting resin (mainly unsaturated polyester resin or epoxy resin) with glass fiber as a reinforcing material, and is called FRP (glass fiber reinforced plastic), but it has the same or better durability than the electric cable to be stored. Most preferred is FRPP (glass fiber reinforced polypropylene) in order to provide years. In order to enhance durability, FRPP may contain carbon. The upper and lower sleeves are generally formed by injection molding, press molding or the like. A communication cable is inserted from both ends in the longitudinal direction of the lower sleeve 12 so that the airtightness is maintained by the end face plate 33 and the adhesive seal material, and the end of the communication cable 41 is inserted into the airtight storage container 10. It is formed to be stored. On the respective split surfaces 36 of the upper sleeve 11 and the lower sleeve 12, vertically symmetrical grooves 31 and 32 that are opposed to each other along the longitudinal direction of the split surface are formed. When the gasket 21 is mounted along the groove 32, the upper sleeve 11 and the lower sleeve 12 are joined by the dividing surface 36 and fixed by the fastening tool 37 to form the cylindrical airtight storage container 10. In addition, the gasket 21 ensures the airtightness of the joint portion. Here, the airtightness is secured by the surface pressure of the surface where the gasket 21 is pressed against the bottom of the groove 31 of the upper sleeve 11 and the groove 32 of the lower sleeve 12. The airtight storage container 10 shown in FIG. 1 forms an airtight closure used for airtightly connecting the ends of the cables.

ガスケット２１には、中央部に２箇所、両端部に２箇所ずつ突起部２２が形成されている。ガスケット２１はこの突起部２２により、下スリーブ１２の分割面３６に形成された溝３２に保持され、取り付け時に下スリーブ１２を傾けたり、装着場所が暗くて見難い場合等でも、ガスケット２１が溝３２から外れることなく装着され、確実に上スリーブ１１と下スリーブ１２との接合面の気密性を保持することができる。これにより、設置環境に影響されることなく確実に気密性を保持することが可能であるとともに、組み立て時における作業性を向上させた気密性収納容器及びそれに用いられるガスケットを提供することができる。   The gasket 21 has two protrusions 22 at the center and two at both ends. The gasket 21 is held in the groove 32 formed on the dividing surface 36 of the lower sleeve 12 by the projection 22, and the gasket 21 is grooved even when the lower sleeve 12 is inclined during installation or the mounting place is dark and difficult to see. Thus, the airtightness of the joint surface between the upper sleeve 11 and the lower sleeve 12 can be reliably maintained. Accordingly, it is possible to provide an airtight storage container and a gasket used for the airtight storage container that can reliably maintain airtightness without being affected by the installation environment and have improved workability during assembly.

ガスケット２１の材質には一般にゴム弾性体が使用できるが、具体的には、ＥＰＤＭ（エチレンプロピレンゴム）を使用するのが最も好ましい。その理由は、ＥＰＤＭは耐久性（耐熱性、耐水性、耐候性、耐寒性、耐オゾン性、永久圧縮歪み等を含む）がバランスよく良好だからである。上下スリーブ１１、１２の溝の開口部の幅（溝の開口部は下スリーブ１２の分割面３６上に存在するが、溝の開口部の幅とは溝の長手方向に対して垂直な方向の開口部の長さをいう）が溝内部の幅（溝内部の幅とは開口部の幅方向と同じ方向の長さをいう）以下の場合、シリコーンゴムやフッ素ゴムもガスケットの材質として使用することができる。その理由はシリコーンゴムやフッ素ゴムは溝の側壁との摩擦力がＥＰＤＭに比べ著しく小さいため、たとえば図２（ｂ）に示すように溝の側壁の形状がテーパー状（溝の底部から溝の開口部の方に向かって溝の側壁間の幅が広くなっている形状）の場合、ガスケットを下スリーブ１２に圧入しても同図の上方向に押し戻されることがあるからである。開口部の幅が溝内部の幅以下の場合、たとえば図２（ｂ）の溝のテーパーが上下逆になっている形状（溝の開口部の方に向かって溝幅が狭くなっている形状）や、同図のテーパーがない場合即ち図の上下方向に対して平行である溝の形状の場合ならば、ガスケットの圧入後にガスケットが上方向に押し戻されることはない。なおこのとき上スリーブ１１の溝にガスケットがはまりにくくならないように溝の開口部の幅は上スリーブ１１の溝内に挿入されるガスケット２１の断面幅よりも大きいことが好ましい。ガスケット２１は一般に射出成形等によって形成される。   A rubber elastic body can be generally used as the material of the gasket 21. Specifically, it is most preferable to use EPDM (ethylene propylene rubber). The reason is that EPDM has good balance in durability (including heat resistance, water resistance, weather resistance, cold resistance, ozone resistance, permanent compression strain, etc.). The width of the opening of the upper and lower sleeves 11 and 12 (the opening of the groove exists on the dividing surface 36 of the lower sleeve 12, but the width of the opening of the groove is perpendicular to the longitudinal direction of the groove). Silicone rubber or fluororubber is also used as a gasket material when the width of the opening is equal to or less than the width inside the groove (the width inside the groove means the length in the same direction as the width of the opening). be able to. The reason is that silicone rubber and fluoro rubber have a remarkably small frictional force with the side wall of the groove as compared with EPDM. For example, as shown in FIG. 2B, the side wall of the groove is tapered (from the bottom of the groove to the opening of the groove). In the case of the shape in which the width between the side walls of the groove becomes wider toward the portion), the gasket may be pushed back upward even if the gasket is press-fitted into the lower sleeve 12. When the width of the opening is equal to or smaller than the width inside the groove, for example, a shape in which the groove taper in FIG. 2B is turned upside down (a shape in which the groove width becomes narrower toward the groove opening). If there is no taper in the figure, that is, in the case of a groove shape parallel to the vertical direction in the figure, the gasket is not pushed back upward after the gasket is press-fitted. At this time, the width of the opening of the groove is preferably larger than the cross-sectional width of the gasket 21 inserted into the groove of the upper sleeve 11 so that the gasket does not easily fit into the groove of the upper sleeve 11. The gasket 21 is generally formed by injection molding or the like.

図２（ａ）はガスケット２１の突起部２２が形成されている部分の長手方向に垂直な断面を示す。ガスケット２１の断面形状は、突起部２２を除いた部分が楕円形であり、突起部２２は楕円の中心から長径方向片側に位置し、短径方向両側に形成されている。図２（ｂ）に示すように、ガスケット２１は長径方向の突起部２２が配置される側が下スリーブ１２に装着される。このとき、ガスケット２１の突起部における幅Ｗ２１（断面の突起部にかかる任意の位置の幅）が、対応する溝３２の幅Ｗ３２（Ｗ２１と同じ位置における幅）より大きく形成されている。そのため、ガスケット２１が、下スリーブ１２の溝３２の側壁間に、突起部２２により圧入によって装着され、溝３２の側壁と突起部２２との面圧によって保持される。   FIG. 2A shows a cross section perpendicular to the longitudinal direction of the portion of the gasket 21 where the protrusion 22 is formed. As for the cross-sectional shape of the gasket 21, the portion excluding the protrusion 22 is elliptical, and the protrusion 22 is located on one side in the major axis direction from the center of the ellipse and is formed on both sides in the minor axis direction. As shown in FIG. 2 (b), the gasket 21 is attached to the lower sleeve 12 on the side where the long-diameter projection 22 is disposed. At this time, the width W21 of the protrusion of the gasket 21 (the width at an arbitrary position on the protrusion of the cross section) is formed larger than the width W32 of the corresponding groove 32 (the width at the same position as W21). Therefore, the gasket 21 is mounted between the side walls of the groove 32 of the lower sleeve 12 by press fitting with the projection 22 and is held by the surface pressure between the side wall of the groove 32 and the projection 22.

ガスケット２１は、下スリーブ１２の溝３２に装着する際に、溝３２の幅Ｗ３２より幅広の部分を形成するが、それは突起部である必要はなく、なだらかに幅が大きくなる部分を形成してもよい。ガスケット２１の幅Ｗ２１が、対応する溝３２の溝幅Ｗ３２より大きい部分が突起部である場合、ガスケット２１の長手方向中央部に少なくとも一つ配置されることが好ましい。中央部を保持することにより、より安定的にガスケットを保持することができるからである。また、図１に示すように、突起部２２が、ガスケット２１の長手方向中央部に少なくとも一つ及び中央部以外の領域に複数配設されることが好ましく、この中央部以外の領域の複数の突起部が両端部にそれぞれ少なくとも一つずつ配設されると更に好ましい。これにより、ガスケット２１が溝３２から外れやすい部分を有効に保持することができるため、ガスケットが施工中に溝から外れることもなく、気密性収納容器１０の気密性を確保することができる。   When the gasket 21 is attached to the groove 32 of the lower sleeve 12, a portion wider than the width W32 of the groove 32 is formed. However, it does not have to be a protrusion, and a portion having a gradually larger width is formed. Also good. When a portion where the width W21 of the gasket 21 is larger than the groove width W32 of the corresponding groove 32 is a protrusion, it is preferable that at least one of the gaskets 21 is disposed at the longitudinal center portion of the gasket 21. It is because a gasket can be hold | maintained more stably by hold | maintaining a center part. Further, as shown in FIG. 1, it is preferable that at least one protrusion 22 is disposed in the central portion in the longitudinal direction of the gasket 21 and a plurality of regions other than the central portion. More preferably, at least one protrusion is provided at each end. Thereby, since the part which the gasket 21 tends to remove | deviate from the groove | channel 32 can be hold | maintained effectively, the airtightness of the airtight storage container 10 can be ensured, without removing a gasket from a groove | channel during construction.

ガスケット２１の突起部は、端部の突起部の高さの方が中央部の突起部の高さよりも小であることが好ましい。突起部２２の高さＨ２２については図２（ａ）に示す。これによって、ガスケット２１を下スリーブ１２の溝３２に圧入により装着したときの、ガスケット２１の突起部２２と溝３２の側壁との間の面圧（保持力）が、ガスケット２１の長手方向の中央部に配設されたものは大きく、端部に配設されたものは小さくなる。あるいは別の形状としては、中央部から端部に向かっていくほど突起部の高さが小である形状が好ましい。これによって、ガスケット２１を下スリーブ１２の溝３２に圧入により装着したときの、ガスケット２１の突起部２２と溝３２の側壁との間の面圧（保持力）が、ガスケット２１の長手方向の中央部に配設されたものほど大きく、中央部から端部へと距離が離れるほど小さくなる。これらの形状を取る結果、気密性収納容器を組み立てる際に、上スリーブ１１と下スリーブ１２とをガスケット２１を介して締結し、締付具３７により締め付けて固定する際に、ガスケット２１の長手方向中央部から締め付け、順次外側に向かって締め付けていくため、端部側の突起部は締め付けられるに従い、更に端部側へと位置がずれることになり、端部側の突起の保持力を小さくすることにより、この移動をスムーズにするのである。これにより、ガスケットに応力歪みが生じ難くなり、気密性も向上する。   The protrusion of the gasket 21 is preferably such that the height of the protrusion at the end is smaller than the height of the protrusion at the center. The height H22 of the protrusion 22 is shown in FIG. Thus, when the gasket 21 is fitted into the groove 32 of the lower sleeve 12 by press fitting, the surface pressure (holding force) between the protrusion 22 of the gasket 21 and the side wall of the groove 32 is the center of the gasket 21 in the longitudinal direction. What is arranged at the part is large, and what is arranged at the end part is small. Or as another shape, the shape where the height of a projection part is so small that it goes to an edge part from a center part is preferable. Thus, when the gasket 21 is fitted into the groove 32 of the lower sleeve 12 by press fitting, the surface pressure (holding force) between the protrusion 22 of the gasket 21 and the side wall of the groove 32 is the center of the gasket 21 in the longitudinal direction. As the distance between the central portion and the end portion increases, the smaller the portion disposed at the portion, the smaller the distance. As a result of taking these shapes, when assembling the airtight storage container, the upper sleeve 11 and the lower sleeve 12 are fastened via the gasket 21, and when fastened by the fastening tool 37, the longitudinal direction of the gasket 21 is fixed. Since tightening from the center and then tightening toward the outside sequentially, as the protrusion on the end side is tightened, the position further shifts to the end side, reducing the holding force of the protrusion on the end side. This makes this movement smooth. Thereby, stress distortion hardly occurs in the gasket, and the airtightness is improved.

下スリーブ１２の溝３２の、長手方向に垂直な断面の溝空間面積Ｓ１に対する、ガスケット２１の突起部２２の部分の長手方向に垂直な断面の、下スリーブ１２の溝３２に装着される側半分の面積Ｓ２（図２（ｂ）の斜線部）の割合（（Ｓ２／Ｓ１）×１００）（％）が、１００〜１３０％であることが好ましい。ガスケット２１の中央部に配設された突起については、１１５〜１２０％が更に好ましい。また、両端部に配設された突起については、１００〜１１５％が更に好ましく、１０５〜１１０％が最も好ましい。これにより、下スリーブ１２の溝３２の溝壁とガスケット２１の突起部２２との面圧をより適正にすることができる。前記割合が１００％より小さいと、溝３２の側壁と接する突起部２２の接触面が小さくなり、所望の保持力が得られないことになる。前記割合が１３０％より大きいと、ガスケット２１が溝３１、３２に入りきれなくなる場合がある。   The side half of the groove 32 of the lower sleeve 12, which has a cross section perpendicular to the longitudinal direction of the projecting portion 22 of the gasket 21, with respect to the groove space area S 1 of the cross section perpendicular to the longitudinal direction. It is preferable that the ratio ((S2 / S1) × 100) (%) of the area S2 (shaded portion in FIG. 2B) is 100 to 130%. About the protrusion arrange | positioned in the center part of the gasket 21, 115-120% is still more preferable. Moreover, about the protrusion arrange | positioned at both ends, 100 to 115% is still more preferable, and 105 to 110% is the most preferable. Thereby, the surface pressure between the groove wall of the groove 32 of the lower sleeve 12 and the protrusion 22 of the gasket 21 can be made more appropriate. If the ratio is smaller than 100%, the contact surface of the protrusion 22 that contacts the side wall of the groove 32 becomes small, and a desired holding force cannot be obtained. If the ratio is larger than 130%, the gasket 21 may not be able to enter the grooves 31 and 32 in some cases.
