Abstract
A sealing mechanism including a first seal member, a second seal member arranged so as to face the first seal member, and a deformed nucleus member arranged in a space formed at least partially between the first seal member and the second seal member, and becoming a nucleus of deformation in the sealing mechanism. The deformed nucleus member is configured by a combination of rod-like members and plate-like members respectively formed from a plurality of materials having different linear expansion coefficients, and is fixed to each of the first seal member and the seal member. The deformed nucleus member contracts in at least one direction on a cross-section of the seal groove, along with an increase in temperature of the deformed nucleus member. The first seal member and the second seal member respectively have abutment surfaces abutting on an inner surface of the seal groove or the facing surfaces.
