Zusammenfassung:	PURPOSE:To maintain good sealing performance even under variable pressure operation, by fitting an inner ring thinner than the outer ring while having diameter same with the seal diameter of seat ring receiver slidably and forming a retainer. CONSTITUTION:A retainer 11 is constructed by fitting an outer ring 11a over an inner ring 11b slidably in axial direction. Both faces of outer ring 11a are maintained approximately perfect planar where the inner ring 11b is thinner than the outer ring 11a while the outer diameter is made same with the seal diameter D of seat ring receiver 34b. Consequently, all forces to be applied onto the outer ring 11a will be the combination of pressure of enclosed liquid and pressing force of spring 37 where they are balanced perfectly to apply no moment onto the opposite side faces of outer ring 11a.
