Abstract
An elastic bushing assembly including a rigid sleeve member disposed radially inwardly of an outer sleeve, the sleeve member having a radial flange extending radially outwardly from one axial end thereof, an elastic member interposed between the outer sleeve and the sleeve member, an inner sleeve disposed radially inwardly of the sleeve member, a sliding member interposed between the inner sleeve and the sleeve member and slidable relative to one of the inner sleeve and the sleeve member. A retainer member is located at one axial end of the inner sleeve corresponding to the radial flange of the sleeve member, and a sealing rubber member is in pressed abutting contact with the radial flange of the sleeve member and the retainer member, so as to provide sealing therebetween. The rubber member includes two radially spaced-apart annular sealing lips whose diameters increase in an axially outward direction of the sleeve member away from the radial flange. The outer sealing lip has a tapered distal end face whose diameter decreases in the axially outward direction.
