<P>PROBLEM TO BE SOLVED: To provide a sealing device which can reduce effectively rotational torque of a rotating side member, and can restrain air from being leaked out of a sealing-objective space. <P>SOLUTION: The sealing device is constituted to seal the annular sealing-objective space S between two members comprising a fixed-side member 7, and a rotating side member 6 supported coaxially and rotatably with respect to the fixed-side member 7, and includes a plurality of elastomer seal lips 15a, 15b fixed onto one 7 of the two members 6, 7, and slide-contacting elastically with the other member 6 out of the two members, and a surface roughness of the most distal side sliding face 13ba of the other member 6 corresponding to the most distal side lip seal 15b positioned in the position most distal from the sealing-objective space S is made higher than a surface roughness of the nearest side sliding face 13aa of the other member 6 corresponding to the nearest side lip seal 15a positioned in the position nearest to the sealing-objective space S. <P>COPYRIGHT: (C)2012,JPO&INPIT |
