- the planar shape of the gasket 100 is a shape corresponding to the outer shape of the opening 210 of the first member 200 and the second member 300. Therefore, the planar shape of the gasket according to the present invention is not limited to the illustrated example, and various shapes (for example, in the case of an annular gasket, the planar shape is circular) can be adopted.
- the gasket 100 is composed of a reinforcing ring 110 made of metal or the like, and a gasket body 120 made of an elastic body (for example, made of rubber) integrally provided on the reinforcing ring 110. ..
- the gasket 100 can be obtained by molding the gasket main body 120 by insert molding using the reinforcing ring 110 as an insert component.
- the reinforcing ring 110 has a body portion 111 extending from the first member 200 side toward the second member 300 side, and a bent portion 112 bent inward from the end portion of the body portion 111 on the first member 200 side.
- the body portion 111 is formed of a tubular portion, and the annular bent portion 112 is formed by a portion of which a part of the tip thereof is bent inward.

Can be done. For example, even in an environment where the pressure inside the gasket 100 (internal pressure) is higher than the pressure outside the gasket 100, the posture of the gasket 100 can be maintained and stable sealing performance can be obtained. Further, the posture of the gasket 100 is stable even in an environment where the dimensional tolerance of the portion where the gasket 100 is mounted becomes relatively large, such as when the materials of the first member 200 and the second member 300 are easily deformed. It is possible to obtain a stable sealing property.
- the outer peripheral side annular projection 125 is configured to be in close contact with the inner peripheral surface 222 of the mounted portion 220. As a result, it is possible to prevent the gasket 100 from falling off from the first member 200 after the gasket 100 is assembled to the first member 200, and the position of the gasket 100 with respect to the first member 200 is displaced. It can be suppressed.
- the protruding height of the second annular protrusion 123 is configured to be smaller than the protruding height of the first annular protrusion 122.

- the gasket 100 is compressed when the gasket 100 is compressed by the first member 200 and the second member 300. The behavior can be made more stable.
- FIG. 5 shows Example 2 of the present invention.
- a case where the shape of the reinforcing ring and a part of the structure of the gasket main body are different from the structure shown in the first embodiment will be shown. Since the basic configuration and operation are the same as those in the first embodiment, the same components are designated by the same reference numerals, and the description thereof will be omitted.
- FIG. 5 is a schematic cross-sectional view of the gasket according to the second embodiment of the present invention, and corresponds to the AA cross-sectional view in FIG.

図1~図4を参照して、本発明の実施例1に係るガスケット及び密封構造について説明する。図1は本発明の実施例に係る密封構造の概略図である。図1においては、密封構造を構成する部材を簡略的に示したもので、その一部については断面的に示している。図2は本発明の実施例に係るガスケットの概略平面図であり、ガスケットの平面図を簡略的に示している。図3は本発明の実施例1に係るガスケットの模式的断面図であり、図2中のAA断面図に相当する。図4は本発明の実施例1に係る密封構造の模式的断面図である。なお、図4中のガスケットは、図2中のAA断面図に相当する。
特に、図1を参照して、本実施例に係る密封構造の概略について説明する。本実施例に係る密封構造は、第1部材200と、第1部材200に固定される第2部材300と、これら第1部材200と第2部材300との間の隙間を封止するガスケット100とを備えている。第1部材200は、開口部210と、開口部210の開口端縁に沿って設けられる環状かつ切り欠き状の被装着部220とを有している。また、本実施例においては、第2部材300には、第1部材200における開口部210に挿入される挿入部310を備えている。そして、ガスケット100は、第1部材200に設けられた被装着部220に装着されることで、第1部材200と第2部材300との間の隙間を封止するように構成されている。なお、第1部材200及び第2部材300の具体例として、第2部材300がコネクタで、第1部材200が、コネクタが装着されるハウジングの場合を例に挙げることができる。
特に、図2及び図3を参照して、本実施例に係るガスケット100について説明する。本実施例に係るガスケット100の平面形状については、その内周面と外周面が略矩形となっている(図2参照)。ただし、ガスケット100の平面形状については、第1部材200の開口部210、及び第2部材300の外形に応じた形状となる。従って、本発明に係るガスケットの平面形状については、図示の例に限らず、各種の形状(例えば、円環状のガスケットの場合には、平面形状は円形状となる)を採用し得る。
特に、図4を参照して、本実施例に係る密封構造について、より詳細に説明する。第1部材200と第2部材300が固定された状態においては、第2部材300における第1部材200との対向面320に、ガスケット本体部120におけるリップ部121が密着する。また、第1部材200における被装着部220は、第2部材300に対向する端面221と、第2部材300における挿入部310の外周面311に対向する内周面222とを備えている。そして、ガスケット本体部120における第1環状突起122と第2環状突起123は、被装着部220における端面221に密着するように構成されている。また、ガスケット本体部120における外周側環状突起125は、被装着部220における内周面222に密着するように構成されている。
本実施例に係るガスケット100によれば、補強環110が設けられているため、ガスケット100の剛性が保たれる。そして、ガスケット本体部120におけるリップ部121は、補強環110における胴体部111の端部からリップ先端に向かうにつれて内側に傾斜するように構成されている。そのため、第1部材200と第2部材300によりガスケット100が圧縮される際においては、リップ部121は、第2部材300における第1部材200との対向面320に押圧されることにより、内側に屈曲した状態で対向面320に密着する。このように、リップ部121の挙動を安定させることができる。
図5には、本発明の実施例2が示されている。本実施例においては、補強環の形状と、ガスケット本体部の構成の一部が、上記実施例1で示した構成とは異なる場合について示す。基本的な構成および作用については実施例1と同一なので、同一の構成部分については同一の符号を付して、その説明は省略する。
