Abstract: A seal body that is used for gas seal includes a seal main body in which a recessed groove is formed by arranging a pair of lips so that the lips face each other; an elastic body that is inserted in the recessed groove and expands the lips; and a rigid body that is installed in the elastic body, and restricts deformation of the elastic body, due to narrowing of the recessed groove, within an elastic deformation range.
