A slidable vibration-isolating rubber member such as a stabilizer bushing or an eye bushing, interposed between two members such that the rubber member is slidable relative to at least one of the two members. The rubber member is formed from a rubber composition which comprises 100 parts by weight of a rubber material, and 2-20 parts by weight of a silicone oil.

Slidable vibration-isolating rubber member

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.

Elastic bushing assembly

A bush assemblage having an inner sleeve, an outer sleeve disposed around the inner sleeve in co-axial and radially-spaced relation thereto, a rigid sleeve member disposed between the inner and outer sleeves, a cylindrical resilient member interposed between the outer sleeve and the rigid sleeve member, and a cylindrical sliding member interposed between the inner sleeve and the rigid sleeve member, a retainer member located at at least one of axial ends of the inner sleeve to extend radially outwardly, and a sealing device for sealing at least between the inner sleeve and the rigid sleeve member. The sealing device includes a rubber member which is disposed on the retainer member and an axial end of the rigid sleeve member corresponding to the at least one axial end of the inner sleeve, and which abuts against the other.
