Abstract
First and second members have substantially different coefficients of thermal expansion, and mutually confronting surfaces. The confronting surface of the first member is covered by a layer of coating material such as protective paint. A jointing construction for jointing between these confronting surfaces includes a gasket sandwiched between the confronting surfaces of the first and the second members, and a layer of bonding material between the gasket and the confronting surface of the second member which bonds the gasket to the second member. Gasket extrusion due to repeated thermal cycling is thereby effectively prevented, and thus this jointing construction with gasket is effective for preventing tearing of the gasket due to extrusion forces acting thereupon, as well as being economical.
