Problems solved by technology

[0004] However, in the case of using a liquid gasket, there is a problem that sealing performance deteriorates over time
In addition, if the sealing surface is enlarged or two sealing lines are provided, the gasket may be tilted or deformed in an environment where the pressure of the sealing fluid is applied to the gasket, and the sealing performance may not be stabilized.

Abstract

Provided are a gasket and a sealing structure capable of exhibiting in a stable fashion a sealing property even when a surface to be sealed is a roughened surface such as a cast skin. A gasket (10) made from a rubber-type elastic body which is mounted in a mounting groove provided on at least one of two members and seals the gap between the two members is characterized in that being provided with: a first seal surface (10a) for contacting with the surface of one of the two members; a second seal surface (10b) for contacting with the surface of the other of the two members; a third seal surface (10c) for contacting with a lateral surface of the mounting groove; and a pressure-receiving groove (11) provided so as to be in parallel to the first seal surface and the second seal surface, the pressure-receiving groove opening on the side subjected to sealed fluid pressure, that being the side opposite from the third seal surface.

Description

technical field [0001] The invention relates to a gasket and a sealing structure for sealing the gap between two parts. Background technique [0002] In recent years, for the purpose of simplifying the manufacturing process, mounting grooves provided in castings such as aluminum die-casting may be used as mounting grooves for gaskets without surface processing. However, in castings, the original casting surface without surface processing has minute unevenness, and relatively large depressions such as blisters are also formed. Therefore, the sealing effect cannot be achieved with a general gasket. [0003] In this regard, in the prior art, the following solutions are adopted, that is, using a liquid gasket, or making the sealing surface an arc shape to increase its area (refer to Patent Document 1), or setting two sealing lines (refer to Patent Document 1). Document 2). [0004] However, in the case of using a liquid gasket, there is a problem that the sealing performance ...
