Abstract
Official abstract text for this publication.
In a sealing device installed to an installation groove which is provided in an outer peripheral surface of one member among two members relatively moving, and sealing between the two members by coming into close contact with the other member which is positioned in an outer peripheral side of the installation groove and one side wall of the installation groove, the sealing device has a seal ring, a support ring having a pressing surface which comes into contact with an inner peripheral corner portion the seal ring, and a spring means which presses the support ring and the seal ring. A collapsing margin in relation to the taper surface shaped pressing surface in the support ring is normally set in an inner peripheral corner portion in the seal ring. According to the sealing device, it is possible to improve pressure resistance and sealing performance.
