Abstract
In a sealing structure, a first component and a second component are sealed with each other with a cured liquid gasket formed on the first member and compressed between the first and second components. The first component is provided with a liquid-repellent portion which is subjected to liquid-repellent processing and a non-liquid-repellent portion which is not subjected to the liquid-repellent processing. The cured liquid gasket is in touch with both the cured and non-cured repellent portions. The sealing structure is capable of suppressing variations in the thickness of the cured liquid gasket, thereby improving sealing performance.
Claims19
A sealing structure provided for a first component and a second component such that the first and second components are sealed by being tightly contacted with each other, wherein
- the first component is provided with a cured liquid gasket, the cured liquid gasket being compressed between the first and second components,
- the first component is provided with a liquid-repellent portion (30) which is subjected to liquid-repellent processing and a non-liquid-repellent portion (41a) which is not subjected to the liquid-repellent processing, and
- the cured liquid gasket is in touch with both the liquid-repellent portion and the non-liquid-repellent portion when being compressed.
A sealing method which manufactures a sealing structure provided for a first component and a second component such that the first and second components are sealed with each other, the sealing method comprising steps of:
- forming, on the first component, a liquid-repellent portion which is subjected to liquid-repellent processing and a non-liquid-repellent portion which is not subjected to the liquid-repellent processing;
- applying a curable liquid composition to a predetermined area including, at least, a part of the liquid-repellent portion on the first component;
- curing the applied curable composition to from the cured liquid gasket;
- compressing the cured liquid gasket between the first and second components such that the non-liquid-repellent portion is tightly in touch with the cured liquid gasket.
An electric apparatus, comprising:
- a first component provided with a space, an electronic device being housed in the space;
- and
- a sealing structure provided for the first component and the second component such that the first and second components are sealed by being tightly contacted with each other, wherein the first component is provided with a cured liquid gasket, the cured liquid gasket being compressed between the first and second components,
- the first component is provided with a liquid-repellent portion which is subjected to liquid-repellent processing and a non-liquid-repellent portion which is not subjected to the liquid-repellent processing, and
- the cured liquid gasket is in touch with both the liquid-repellent portion and the non-liquid-repellent portion when being compressed.
