1. An annular gasket comprising:
- an annular solid sealing portion adapted to be engaged by and pressed between adjacent surfaces of two objects; and
an annular solid deformation stopper portion which is thinner than said annular solid sealing portion in a direction of compression of said annular gasket, said annular solid deformation stopper portion being positioned either radially outside or radially inside of and formed integrally with said annular solid sealing portion such that said annular solid deformation stopper portion is adapted to be engaged by the adjacent surfaces of the two objects when said annular solid sealing portion has been compressively deformed in the direction of compression of said annular gasket by a predetermined amount by the adjacent surfaces so as to prevent excessive deformation of said annular solid sealing portion.

Abstract
There is provided a gasket comprising a sealing portion and a deformation stopper portion. When the gasket is placed between adjacent surfaces to be sealed of two objects, the sealing portion is engaged by the adjacent surfaces. The deformation stopper portion is engaged by the adjacent surfaces of the objects when the sealing portion has been deformed by a predetermined amount by the adjacent surfaces, thereby preventing excessive deformation of the sealing portion.
