<P>PROBLEM TO BE SOLVED: To provide a sealing device capable of reducing slide resistance between a seal body and a slinger. <P>SOLUTION: The sealing device is mounted in an annular space S formed between a rotary shaft 2 and a fixed ring 3 that are concentrically disposed, and prevents the intrusion of a foreign matter from the outside A1 of the annular space S. The sealing device is provided with the slinger 11 and the seal body 12. The slinger 11 includes a cylindrical part 21 attached to the rotary shaft 2 and a flange 22 extended outward in the radial direction from the cylindrical part 21 via an elastic body 23. The seal body 12 includes a main lip 33 slidable with the cylindrical part 21 and a side lip 35 slidable with the side face 22a of an outer side A1 of the flange 22. The position G1 of the center of gravity in the cross section of the flange 22 is located at the outer side A1 from the position G2 of the center of gravity in the cross section of the elastic body 23. <P>COPYRIGHT: (C)2013,JPO&INPIT |
