Abstract
In a gasket which is installed to an installation groove provided in one member of two members facing to each other and comes into close contact with the other member, and has a seal projection coming into contact with a groove side surface of the installation groove, and provided over a whole periphery of the gasket in a side surface of the gasket, a concavity is provided in a part on a circumference of the gasket in the side surface of the gasket, for venting air when the gasket is installed to the installation groove. The concavity is formed into a shape having a predetermined curvature in a longitudinal direction of the gasket. The gasket can prevent the pressing resistance at a time of installing the gasket from being enlarged, and prevent the gasket from floating up from the installation groove due to the spring back of the sealed air.
