A solid, dry to the touch at ambient temperature, heat curable, generally non-foaming structural adhesive that exhibits shape memory characteristics. The adhesive can be cured at an elevated temperature and contains a high molecular weight polymeric constituent that can be oriented such that at an elevated temperature below the curing temperature the material will shrink in one plane while increasing its thickness at a temperature in the range of from above the elevated temperature to below the curing temperature.

The present invention is intended to provide a machine component composed of metal and rubber that results in no increase of material costs for an adhesive or increase of manufacturing costs for metal molding, causes no contamination of the metal mold or generates no foreign matter on the metal mold due to adhesion of the adhesive at the time of molding, causes no failure by separation of the adhesive from a fitting portion at the time of fitting the metal component, and is clean and favorable in appearance. A machine component 1 composed of metal and rubber is formed by applying a thermoset resin adhesive A to a surface of a metal component 2 of a predetermined shape, and vulcanizing and adhering a rubber 3 of a predetermined shape to part of the surface of the metal component 2 by metal molding.
