The abutment part side is set thinnest, and the opposite abutment part side is set thickest. Thickness of the abutment part in the diametrical direction is 50 to 70% of that of the opposite abutment part in the diametrical direction. The pressure ring 1 can be manufactured only by cutting or grinding an outer peripheral face of a ring material body having constant thickness in the diametrical direction.
