Abstract

PROBLEM TO BE SOLVED: To provide a shutter opening/closing mechanism of an airtight device which has a simple structure and is at low cost, reliably maintains a sealed state, and has excellent durability.SOLUTION: The shutter opening/closing mechanism of the airtight device comprises a baseplate 20, a shutter plate 30, support means 32, a guide rail of a shutter plate 40, linear driving means 50, a connection arm 60, a stopper 70, a guide roller for a connection arm 80, and a rail for a guide roller for a connection arm 82. The support means 32 is equipped with a guide roller for the support means 34 at one end and is connected to an elastic member 36, which end is fixed on the shutter plate 30, at another end. When the shutter plate contacts the stopper 70, the connection arm 60 gets to an upright state, the shutter plate 30 is pressed to the baseplate 20, and the elastic member 36 becomes extended, such that the sealed state is maintained. Consequently, the shutter opening/closing mechanism of the airtight device, which can reduce friction between the shutter plate and a wall surface, ensure a tight sealing of even small openings, and effectively prevent vibrations, can be obtained.

Description

本発明は、装置内部の気密性を確保・維持することが求められる気密装置の開口部をシャッタ板によって密閉するための気密装置シャッタ開閉機構に関する。   The present invention relates to an airtight device shutter opening / closing mechanism for sealing an opening of an airtight device that is required to maintain and maintain the airtightness inside the device with a shutter plate.

空気中では不安定な物質、放射性物質等の危険・有害な物質や薬品を取扱う場合等に、真空状態、不活性ガス注入状態で作業を行うことを可能とし、また、取扱者の安全を確保するためのグローブボックスが知られている。医薬品の試験や土壌分析、半導体等、様々な分野で活用されている。また、このようなグローブボックスに限らず、装置内部での目的物の洗浄等、その他様々な用途のため、装置を確実に密閉し、且つ、その密閉機能を長期に渡って維持することが求められる種々の密閉装置がある。
しかし、このような気密装置の開口部における隙間を確実に塞ぎ、且つ、そのような密閉機能を長期間維持することは、必ずしも容易ではない。
When handling unstable or radioactive substances such as unstable substances and radioactive substances in air, it is possible to work under vacuum and inert gas injection, and to ensure the safety of operators. A glove box is known for doing this. It is used in various fields such as pharmaceutical testing, soil analysis, and semiconductors. In addition to such a glove box, it is required to securely seal the device and maintain its sealing function for a long period of time for various other uses such as cleaning of the object inside the device. There are various sealing devices that can be used.
However, it is not always easy to reliably close the gap in the opening of such an airtight device and maintain such a sealing function for a long period of time.

このような課題を解決するため、例えば、特許第3622873号のような手段が提供されている。この発明は、「IC試験用恒温槽」に関するものであり、搬入口を開閉するシャッタ板の先端部分にテーパ面を形成し、閉位置においてこのテーパ面に係合する係合子を設け、この係合子とテーパ面との係合によってシャッタ板を恒温槽の壁面に圧接させるとともに、シャッタ板を移動させる直線駆動手段との間に、シャッタ板を恒温槽の壁面と直交する方向に移動可能とする支持手段と、壁面から引き離す方向に偏倚力を与える偏倚手段とを設けたものである。
この発明によれば、シャッタ板は偏倚手段によって恒温槽の壁面から離れる方向に偏倚されるから、移動中は恒温槽の壁面に触れることはなく、閉位置に近い僅かな距離だけ、恒温槽の壁面に摺動し、摩耗の発生を極力少なくすることができる、また、閉位置に到達した状態でテーパ面が係合子と係合し、この係合によって恒温槽の壁面にシャッタ板を圧接させることができるとされている。
In order to solve such a problem, for example, means such as Japanese Patent No. 3622873 is provided. The present invention relates to an “IC test thermostat”, and a tapered surface is formed at the front end portion of a shutter plate that opens and closes a carry-in port, and an engagement element that engages with the tapered surface is provided at a closed position. The shutter plate is brought into pressure contact with the wall surface of the thermostatic chamber by engagement between the coupling and the tapered surface, and the shutter plate can be moved in a direction orthogonal to the wall surface of the thermostatic chamber between the linear drive means for moving the shutter plate. Supporting means and biasing means for applying a biasing force in a direction away from the wall surface are provided.
According to this invention, the shutter plate is biased in the direction away from the wall surface of the thermostatic chamber by the biasing means, so that it does not touch the wall surface of the thermostatic chamber during movement, but only a slight distance close to the closed position during the movement. It can slide on the wall surface to reduce the generation of wear as much as possible, and the taper surface engages with the engagement element when reaching the closed position, and the shutter plate is pressed against the wall surface of the thermostatic chamber by this engagement. It is supposed to be possible.

また、特許第2759867号の発明は、開口部にシール部材を装着し、ガイドレールの一方に駆動手段を設け、回転駆動軸、弾発手段等の多数の部材の連動により、シール部材を押圧して開口部を閉塞する、液槽のドア式気密閉塞装置を提供する。
同発明によれば、駆動手段の駆動力と、移動抑制手段の反力により閉塞蓋を強力に押圧して液槽の開口部を閉塞するようにしているから、液槽の開口部を効率的に閉塞することができ、また、移動時にシャッタ板がシール部材に接触しないようにしたので、シール部材の摩耗を防止することができ、寿命を延ばすことができるとされている。
In the invention of Japanese Patent No. 2759867, a seal member is attached to the opening, a drive means is provided on one side of the guide rail, and the seal member is pressed by the interlocking of a large number of members such as a rotary drive shaft and a resilient means. A liquid tank door-type airtight closing device that closes the opening is provided.
According to the invention, since the opening of the liquid tank is closed by strongly pressing the closing lid by the driving force of the driving means and the reaction force of the movement suppressing means, the opening of the liquid tank is efficiently In addition, since the shutter plate is prevented from coming into contact with the seal member during the movement, the wear of the seal member can be prevented and the life can be extended.

特許第3622873号Japanese Patent No. 3622873 特許第2759867号Japanese Patent No. 2759867

しかし、特許文献1の発明においては、テーパ面が係合子に係合することにより、シャッタ板が徐々に壁面に圧接されるため、開閉時にやはり摺動摩耗を伴い、耐久性に乏しく、長期間に渡る気密性の維持を確保できない恐れがある。また、直線駆動手段とシャッタ板は、L字金具を介して一点で連結されているに過ぎないため、シャッタ板の開閉動作が不安定なものとなる。さらに、複数部材にテーパ加工を行えば、コストも嵩む。   However, in the invention of Patent Document 1, since the shutter surface is gradually pressed against the wall surface by engaging the taper surface with the engagement element, sliding wear is also accompanied at the time of opening and closing, and the durability is poor, and the long term. There is a risk that it will not be possible to secure the airtightness over the range. Further, since the linear driving means and the shutter plate are merely connected at one point via the L-shaped metal fitting, the opening / closing operation of the shutter plate becomes unstable. Furthermore, if a plurality of members are tapered, the cost increases.

また、特許文献2の発明においては、開口部を囲繞するシール部材を装着する必要があるから、そのためのコストや取付手間がかかる上、駆動手段が液槽の片側に取付けられているため、回転駆動軸をその両側において支持する部材その他多数の部材が必要となり、構造が複雑となる。さらに、閉塞蓋をシール部材から離反させる弾発手段が設けられてはいるが、閉塞蓋の取付方向が、天井取付け、傾斜取付け等になった場合、蓋のがたつきを抑える手段がない。   Further, in the invention of Patent Document 2, since it is necessary to attach a seal member that surrounds the opening, it takes cost and labor for that, and the drive means is attached to one side of the liquid tank, so that rotation is possible. A member that supports the drive shaft on both sides thereof and many other members are required, and the structure becomes complicated. Furthermore, although a resilient means for separating the closing lid from the seal member is provided, there is no means for suppressing the rattling of the lid when the direction of attachment of the closing lid is ceiling mounting, inclined mounting, or the like.

そこで、本発明は、簡易な構造且つ低コストで、シャッタ板と気密装置壁面との僅かな隙間も確実に密閉し、繰返しの開閉に伴うシャッタ板と壁面との摩耗を低減し、あらゆる取付方向に対応可能な、気密装置のシャッタ開閉機構を提供することを目的とする。   Therefore, the present invention has a simple structure and low cost, reliably seals a slight gap between the shutter plate and the airtight device wall surface, reduces wear between the shutter plate and the wall surface due to repeated opening and closing, and can be installed in any mounting direction. It is an object of the present invention to provide a shutter opening / closing mechanism of an airtight device that can cope with the above.

The present invention is an airtight device shutter opening and closing mechanism for sealing the opening of the airtight device with a shutter plate,
A base plate, a shutter plate, support means for the shutter plate, a shutter plate guide rail, linear drive means, a connection arm connecting the shutter plate and the linear drive means, a connection arm guide roller, and a connection arm guide roller Rail and a stopper provided on the closed position side of the base plate,
The support means is disposed at least one on each side of the shutter plate, and has a support means guide roller fitted into the shutter plate guide rail at one end portion, and one end of the support means with respect to the shutter plate at the other end portion. The elastic member fixed in this way is connected, and is installed swingably on a support base provided on the shutter plate,
The connecting arm is configured such that a first connecting portion with a tip portion of the linear driving means and a second connecting portion with the shutter plate are rotatable.
The connecting arm guide roller is attached to the first connecting portion of the connecting arm, and is fitted into the rail for the connecting arm guide roller fixed on the base plate,
The linear drive means comprises drive restriction means that operates when the connecting arm is in an upright state,
When the shutter plate comes into contact with the stopper, the connecting arm is brought into an upright state by extension of the linear drive means, the shutter plate is pressed against the base plate, and the elastic member is moved by swinging of the support means. In the extended state, the operation of the linear drive means is stopped by the operation of the drive restricting means, and it is in a sealed state,
By the airtight device shutter opening / closing mechanism, the pressing force between the shutter plate and the base plate is released by the biasing force accompanying the reactivation of the linear drive means and the extension of the elastic member, and the shutter is opened again. Solved the problem.

本発明によれば、シャッタ板は、連結アームが直線駆動手段の伸長に伴い回動して直立状態となる動作を利用して、シャッタ板とベースプレートとを密着させるため、テーパ加工を施したり、テーパ部材を用いる必要がない。また、テーパ面を徐々に密着させることがないから、密閉の前後に摺動、摩耗を生じることがなく、耐久性が向上する。
そして、シャッタ板の移動距離は連結アームの構成により自在に調整可能であり、僅かな隙間も密閉することができる。また、複数箇所でシャッタ板を支持しているため、シャッタ板の開閉を安定的且つスムーズに行うことができる。
さらに、連結アームによる押圧力と支持手段に連結された弾性部材の弾性力によって密閉状態が維持されるから、水平、垂直、天井取付等、あらゆる取付方向に対応可能であり、シャッタ板の振動・がたつきを抑えることができる。また、密閉状態において、弾性部材が伸張することにより、シャッタ板をベースプレートから引離す方向に偏倚力が働いているから、スムーズに開状態に移行することができる。
本発明は、簡易な構造且つ低コストで、上記効果を奏する気密装置シャッタ開閉機構を提供する。
According to the present invention, the shutter plate is subjected to a taper process in order to bring the shutter plate and the base plate into close contact with each other by using an operation in which the connecting arm rotates and rotates in accordance with the extension of the linear drive means. There is no need to use a taper member. Further, since the taper surface is not gradually brought into close contact, sliding and wear do not occur before and after sealing, and durability is improved.
The moving distance of the shutter plate can be freely adjusted by the structure of the connecting arm, and even a slight gap can be sealed. In addition, since the shutter plate is supported at a plurality of locations, the shutter plate can be opened and closed stably and smoothly.
Furthermore, since the sealed state is maintained by the pressing force of the connecting arm and the elastic force of the elastic member connected to the support means, it can be used in any mounting direction such as horizontal, vertical, ceiling mounting, etc. The rattling can be suppressed. Further, in the sealed state, when the elastic member expands, a biasing force is acting in the direction of pulling the shutter plate away from the base plate, so that it can smoothly shift to the open state.
The present invention provides an airtight device shutter opening / closing mechanism that achieves the above effects with a simple structure and low cost.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view of an airtight device shutter opening / closing mechanism 10 of the present invention, and FIG. 2 is a cross-sectional view taken along line 2-2 of FIG.
The airtight device shutter opening / closing mechanism 10 of the present invention includes a base plate 20, a shutter plate 30, a shutter plate guide rail 40, a linear driving means 50, a connecting arm 60 that connects the shutter plate 30 and the linear driving means 50, a stopper 70, and a connecting arm. A guide roller 80 and a connecting arm guide roller rail 82 are provided. The base plate 20 is a wall surface of the opening of the hermetic device, and the linear drive means 50 further includes drive restriction means 52.
As shown in FIGS. 1 and 2, the connecting arm guide roller rail 82 includes a rail support base 84 provided on the base plate 20 on the front side of the shutter plate and a gate-shaped member 86 fixed on the shutter plate guide rail 40. It is fixed by.

図3は、本発明の気密装置シャッタ開閉機構の構造及び作用を示す側面図であり、(a)ではシャッタ板は閉位置にあるものの開状態であり、(b)は密閉状態を示している。
図3(a)から分かるように、開状態において、シャッタ板30は、支持手段32及びシャッタ板ガイドレール40によって、ベースプレート20との間に一定の隙間Δが形成されるように、また、直線駆動手段50の駆動に伴い気密装置の開口面に沿って平行移動できるように支持されている。本実施形態において、直線駆動手段50はボールねじを用いた直線作動機である。
FIG. 3 is a side view showing the structure and operation of the shutter opening / closing mechanism of the hermetic device according to the present invention. In FIG. 3, (a) shows the shutter plate in the closed position but in the open state, and (b) shows the sealed state. .
As can be seen from FIG. 3A, in the open state, the shutter plate 30 is linearly formed so that a fixed gap Δ is formed between the support plate 32 and the shutter plate guide rail 40 and the base plate 20. As the driving means 50 is driven, it is supported so that it can be translated along the opening surface of the hermetic device. In this embodiment, the linear drive means 50 is a linear actuator using a ball screw.

図3において、支持手段32は、く字型アームを有するカムフォロアであり、その一端部32aに支持手段ガイドローラ34を具えている。この支持手段ガイドローラ34は、シャッタ板ガイドレール40の溝に嵌挿されており、これによって、シャッタ板30が直線駆動手段50の駆動に伴い、ベースプレート20との間に一定の隙間Δを維持しながらベースプレート20上を平行移動できるようになっている。
本実施形態において、支持手段32は、シャッタ板30の両側部に2箇所ずつ、計4箇所に設けられているが、少なくとも、両側部に1箇所ずつ、計2箇所に設けられていればよい。密閉状態を確実に実現・維持するためには、本実施形態のように、4箇所に設けることが好ましい。
In FIG. 3, the support means 32 is a cam follower having a square arm, and has a support means guide roller 34 at one end 32a thereof. The support means guide roller 34 is inserted into the groove of the shutter plate guide rail 40, and thereby, the shutter plate 30 maintains a constant gap Δ between the base plate 20 and the shutter plate 30 as the linear drive means 50 is driven. The base plate 20 can be translated in parallel.
In the present embodiment, the support means 32 is provided at a total of four locations, two on each side of the shutter plate 30, but it is sufficient that the support means 32 is provided at a total of two locations, one on each side. . In order to reliably realize and maintain the sealed state, it is preferable to provide at four places as in this embodiment.

支持手段32のアームの他端部32bには、弾性部材36が連結されている。本実施形態において、弾性部材36はコイルばねである。弾性部材36の他端は、シャッタ板30上に設けられたアーム支持台38の側面に固定されている。これにより、支持手段32は、シャッタ板の開閉に伴い、揺動可能となっている。
アーム支持台はシャッタ板と一体的に形成されてもよく、この場合弾性部材はシャッタ板の側面に固定される。いずれにせよ、弾性部材はシャッタ板に対して固定されていればよい。
An elastic member 36 is connected to the other end 32 b of the arm of the support means 32. In the present embodiment, the elastic member 36 is a coil spring. The other end of the elastic member 36 is fixed to a side surface of an arm support base 38 provided on the shutter plate 30. Thereby, the support means 32 can be swung with the opening and closing of the shutter plate.
The arm support may be formed integrally with the shutter plate. In this case, the elastic member is fixed to the side surface of the shutter plate. In any case, the elastic member may be fixed to the shutter plate.

また、図3(a)、(b)に示すように、連結アーム60は、シャッタ板30の上面に固定された連結アーム取付台62を介して、シャッタ板30と駆動手段50のパワーシリンダ先端部とを連結しており、揺動可能となっている。
すなわち、連結アーム60は、駆動手段50先端部との第1連結部64、連結アーム取付台62との第2連結部66とを有し、それぞれが回動可能なように構成されている。第1連結部64には連結アームガイドローラ80が取付けられており、これが連結アームガイドローラ用レール82に嵌挿されている。そして、連結アーム60は、通常時は駆動手段50側に傾斜した状態で、連結アームガイドローラ用レール82に沿ってガイドされるが、シャッタ板30がストッパ70に当接し、シャッタ板の進行が停止すると、駆動手段50のさらなる伸長に伴い、第2連結部66を支点として回動し、直立状態となるように構成されている。
連結アーム60には、カム機構を用いてもよい。
3A and 3B, the connecting arm 60 is connected to the shutter plate 30 and the front end of the power cylinder of the drive means 50 via a connecting arm mounting base 62 fixed to the upper surface of the shutter plate 30. Are connected to each other and can swing.
That is, the connecting arm 60 has a first connecting part 64 with the tip of the driving means 50 and a second connecting part 66 with the connecting arm mounting base 62, and each is configured to be rotatable. A connecting arm guide roller 80 is attached to the first connecting portion 64, and this is inserted into the connecting arm guide roller rail 82. The connecting arm 60 is normally guided along the connecting arm guide roller rail 82 while being inclined toward the driving means 50, but the shutter plate 30 abuts against the stopper 70, and the shutter plate advances. When the driving means 50 is stopped, the second connecting portion 66 is pivoted about the fulcrum as the driving means 50 is further extended, and is in an upright state.
A cam mechanism may be used for the connecting arm 60.

以下、本発明の気密装置シャッタ開閉機構10の作用を説明する。
シャッタ板30は、図1の破線で示す開位置から、駆動手段50の伸長によってベースプレート20上を平行移動させられる。閉位置に至ると、シャッタ板30の先端部が、ストッパ70に当接するが、駆動手段50はさらに伸長しシャッタ板を前方に押し続ける。このため、連結アーム60は、連結アーム取付台62との第2連結部66を支点として回動し、次第に直立状態となる。
The operation of the airtight device shutter opening / closing mechanism 10 of the present invention will be described below.
The shutter plate 30 is translated on the base plate 20 from the open position indicated by the broken line in FIG. When the closed position is reached, the tip of the shutter plate 30 comes into contact with the stopper 70, but the driving means 50 further expands and continues to push the shutter plate forward. For this reason, the connecting arm 60 turns around the second connecting portion 66 with the connecting arm mounting base 62 and gradually becomes upright.

支持手段32の一端部32aは、支持手段ガイドローラ34を介して、シャッタ板ガイドレール40の溝に嵌挿されているから、シャッタ板30の動きはその限度で規制されている。また、連結アーム60も、連結アームガイドローラ80を介して、連結アームガイドローラ用レール82によってガイドされるように構成されているため、図3における鉛直方向の動きが規制されている。このため、連結アーム60が直立状態となるにつれ、シャッタ板30は気密装置の開口側に押され、最終的にベースプレート20に押圧され、気密装置は密閉状態となる。
シャッタ板30がベースプレート20側に押圧されるのに伴い、支持手段32の他端部32bも、ベースプレート20側に引っ張られ、弾性部材36のコイルばねを伸長させる。
Since the one end portion 32a of the support means 32 is inserted into the groove of the shutter plate guide rail 40 via the support means guide roller 34, the movement of the shutter plate 30 is restricted to that limit. Further, since the connecting arm 60 is also configured to be guided by the connecting arm guide roller rail 82 via the connecting arm guide roller 80, movement in the vertical direction in FIG. 3 is restricted. For this reason, as the connecting arm 60 is in the upright state, the shutter plate 30 is pushed toward the opening side of the hermetic device, and finally is pushed by the base plate 20, so that the hermetic device is hermetically sealed.
As the shutter plate 30 is pressed toward the base plate 20, the other end 32 b of the support means 32 is also pulled toward the base plate 20, thereby extending the coil spring of the elastic member 36.

連結アーム60が直立状態となると、駆動手段50に取付けられた駆動規制手段52が作動し、駆動手段50の動作を停止させる。本実施形態において、駆動規制手段52は、連結アーム60が直立状態となった時に動作するように設定されたリミットスイッチである。このリミットスイッチが作動し、連結アーム60が直立となった状態で駆動手段50の動作が停止するから、連結アーム60による押圧力と弾性部材36の弾性力によって密閉状態が維持される。これにより、シャッタ板の振動・がたつきを防ぐことができる。
また、図3に示すように、シャッタ板30のベースプレートとの当接面に、シール部材90を取付けると、密閉状態を確実にし、流体の漏れを防ぐことができる。シール部材としては、Oリング等を用いることができる。
When the connecting arm 60 is in an upright state, the drive restricting means 52 attached to the drive means 50 is activated, and the operation of the drive means 50 is stopped. In the present embodiment, the drive restricting means 52 is a limit switch that is set to operate when the connecting arm 60 is in an upright state. Since the operation of the driving means 50 is stopped in a state where the limit switch is activated and the connecting arm 60 is upright, the sealed state is maintained by the pressing force by the connecting arm 60 and the elastic force of the elastic member 36. Thereby, the vibration and rattling of the shutter plate can be prevented.
In addition, as shown in FIG. 3, when a seal member 90 is attached to the contact surface of the shutter plate 30 with the base plate, a sealed state can be ensured and fluid leakage can be prevented. An O-ring or the like can be used as the seal member.

次に、この密閉状態から再び開状態とするには、駆動手段50を作動させて、連結アーム60の直立状態を解き、図3(a)の傾斜状態とする。
上記のとおり、連結アーム60を直立させて密閉状態とする際、支持手段32の他端部32bは、ベースプレート20側に引っ張られ、これに伴い弾性部材36のコイルばねが伸長しているから、支持手段32には、シャッタ板30をベースプレート20から引離す方向に偏倚力が働いている。従って、密閉状態実現のためにシャッタ板30及びベースプレート20にかけられていた圧力はスムーズに解かれ、気密装置は再び開状態となる。連結アーム60が通常の傾斜状態となった後、駆動手段50が伸長した距離を戻ると、シャッタ板30は、再び図1に破線で示した開位置に至る。
Next, in order to return from the sealed state to the open state again, the driving means 50 is operated to release the upright state of the connecting arm 60 to the inclined state of FIG.
As described above, when the connecting arm 60 is kept upright and sealed, the other end portion 32b of the support means 32 is pulled toward the base plate 20, and the coil spring of the elastic member 36 is extended accordingly. A biasing force acts on the support means 32 in a direction in which the shutter plate 30 is separated from the base plate 20. Therefore, the pressure applied to the shutter plate 30 and the base plate 20 for realizing the sealed state is released smoothly, and the hermetic device is opened again. When the driving arm 50 returns to the extended distance after the connecting arm 60 is in the normal inclined state, the shutter plate 30 reaches the open position indicated by the broken line in FIG.

上記に実施形態として示した支持手段32、弾性部材36、アーム支持台38、駆動手段50、駆動規制手段52、レール支持台84、門形部材86等は一例であって、その他種々の構成を採ることができる。   The support means 32, the elastic member 36, the arm support base 38, the drive means 50, the drive restricting means 52, the rail support base 84, the gate-shaped member 86, and the like shown as the embodiments are examples, and other various configurations are possible. Can be taken.

なお、シャッタ板30の動作を閉位置で規制するストッパ70は、潤滑性のある樹脂材や表面処理材、軸受を具えた回動可能なものとすると、開状態・密閉状態間におけるシャッタ板30の動作をさらにスムーズにすることができるため、好ましい。図示しているのは、軸受を具えた回動可能なストッパの一例である。
また、ベースプレート20及び/又はシャッタ板30の当接面に、シール部材を装着すると、密閉状態をさらに確実に実現・保持できるから、用途に応じて付加するとよい。本実施形態においては、シャッタ板30がOリングを具える構成を例示したが、これに限定されず、種々の構成を採ることができる。
If the stopper 70 that restricts the operation of the shutter plate 30 at the closed position is rotatable with a resin material, a surface treatment material, and a bearing having lubricity, the shutter plate 30 between the open state and the sealed state is provided. This is preferable because the operation can be made smoother. Shown is an example of a rotatable stopper with a bearing.
Further, if a sealing member is attached to the contact surface of the base plate 20 and / or the shutter plate 30, a sealed state can be more reliably realized and held, so it may be added depending on the application. In the present embodiment, the configuration in which the shutter plate 30 includes an O-ring is illustrated, but the present invention is not limited to this, and various configurations can be adopted.
