<P>PROBLEM TO BE SOLVED: To provide an improved seal device for a shock absorber capable of reducing a frictional force and permanently keeping its sealing performance. <P>SOLUTION: This seal device includes an approximately annular body 10 of rubber or an elastomeric material associated with an annular reinforcing insert 20. The body 10 forms an oil-guard lip 15, a dust-cover lip 12 and a peripheral static sealing lip 13. The insert 20 is made of a plastic material and forms a discoidal annular portion 21 for supporting and connecting the lips 12, 13 and 15. The insert 20 also forms a reinforcing structure 22 which projects axially from a radially internal region of the discoidal portion 21 and which is attached to the oil-guard lip 15 in order to ensure that that lip exerts controlled radial contact pressure against the stem S of the shock absorber. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
