<P>PROBLEM TO BE SOLVED: To provide an annular sealing device increasing sealability of a metallic contact part with simple structure to respond to a shape characteristics of a part to be sealed. <P>SOLUTION: The annular sealing device 5 includes: a core 7, and a seal lip member 8 made of an elastic body stuck integrally with the core. The annular sealing device 5 is installed between a metallic outer member 2 with an inner member 3 having a flange part 3a, which are relatively and axially rotated and concentric with each other. The core includes: a fitting cylinder part 71 press-fitted into an inner peripheral part 2a of the outer member; and an outward collar part 73 including an abutment part 74 directly abutting on a flange part side end face part 2b in the outer member; and an inward collar part 73. The seal lip member includes: a lip base part 80; and a plurality of annular lips 82-85 concentrically extended from the lip base part. The annular lip includes: an axial lips 82, 83; and an outer lip 84 in slide-contact with or close to the flange part; and a gasket lip 85 elastically in contact with an end face part of the outer member with compressed state along an axial direction, on an outer diameter side of the abutment part. <P>COPYRIGHT: (C)2011,JPO&INPIT |
