摘要： A sealing device having a metallic ring (2) is provided in which, even when the degree of flatness of a pressing part (5) or a flange part (6) of the metallic ring (2) is not strictly regulated, the radial-direction position where the part (5) or (6) is in contact with a mating member (11) can be stabilized and the circumferential-direction distribution of pressure on the mating material (11) can be stabilized. The sealing device comprises a metallic ring (2) and a sealing part, e.g., a packing, wherein the metallic ring (2) has an annular pressing part (5) which has a given radial-direction width and presses the mating material (11) when the metallic ring (2) shifts in the axial direction. The pressing part (5) has a pressing surface (7) which has been formed so as to have an arc-form or wavy section projecting toward the mating member (11). The pressing part (5) comprises a flange part (6) projecting outward and integrally molded with the edge of a cylindrical part (4) of the metallic ring (2). The flange part (6) has a smaller wall thickness than the cylindrical part (4), and has been formed so as to have an arc-form or wavy section and hence have spring properties.

摘要： A sealing device (1) which makes it unnecessary to insert a plate spring as a separate part between a metal ring (2) and a mating member (11) to be coupled therewith such as a clutch plate, thereby making it possible to reduce the number of parts and the assembly manhours. The sealing device (1) includes the metal ring (2) and seal sections (3) such as packings supported by the metal ring (2), and the metal ring (2) is provided with a intimate-contact region (4) for intimately contacting to the mating member (11) to be coupled. The sealing device (1) is characterized in that the intimate-contact region (4) of the metal ring (2) is integrally formed with pawl-like intimate-contact sections (6) which are in the form of a pawl and which exert spring force on the mating member (11) to be coupled. The sealing device (1) is used, for example, as a bonded piston seal (BPS) in an automatic transmission.
