An upper mount in a suspension system of an automotive vehicle, including a metal housing, a cylindrical body accommodated in the housing, and an outer metal sleeve bonded to the outer circumferential surface of the elastic body and fitted in the housing, wherein the elastic body has an annular sealing lip integrally formed of a rubber material and located radially outwardly of a central opening formed through an upper wall portion of the housing such that the sealing lip is held in pressing contact with an inner surface of the upward wall portion or a cylindrical wall portion of the housing, for preventing a flow of an aqueous component such as water from the central opening to the outer metal sleeve.

Upper mount of vehicle suspension, including elastic body fixed in metal housing and having sealing lip in contact with inner surface of the housing

An upper support for a wheel suspension system of a vehicle having a shock absorber, which comprises an inner member connected to a piston rod of the shock absorber, an outer sleeve member disposed radially outwardly of the inner member and fixed to the vehicle body, and an elastic body interposed between the inner and outer sleeve members. The outer member has an upper and lower stop portions formed at axially opposite open-end portions thereof, so as to extend radially inwardly. The elastic body is bonded at its inner circumferential surface to the outer circumferential surface of the inner member, and is held in close contact at its outer circumferential surface with the inner circumferential surface of the outer sleeve member, while being held in abutting contact at its axially opposite end faces with the upper and lower stop portions of the outer sleeve. The upper support further includes an upper and lower elastic protrusions which protrude axially upwardly and downwardly from the inner member, and which is brought into abutting contact with the upper and lower stop portions. The elastic body is compressed by the outer sleeve member in the radial direction so that the elastic body exhibits a shear strain of not greater than 1, upon application of an axial load of 1000N between the inner and the outer sleeve members in a bound direction.
