Patent ID: 8292312

Claim:
A stabilizer bushing for a vehicle, comprising: a bushing body made of a tubular elastic body having an inner bore that extends therethrough in an axial direction thereof and respective opposite ridges integrally formed on an outer circumferential surface of respective opposite axial end portions of the bushing body, wherein a stabilizer bar is inserted into the inner bore without bonding thereto, the bushing body being mounted to a vehicle body by a bracket that is assembled to the outer circumferential surface of the bushing body; two partition members embedded in a middle area of the bushing body with respect to a radial direction of the bushing body and bonded thereto by vulcanization in such a way that each of the two partition members divides the bushing body into an inner rubber portion and an outer rubber portion, each of the two partition members being rigid and having a semi-tubular shape; and a sliding member fixed to an inner circumferential surface of the inner bore, the sliding member being slidably contacted with the stabilizer bar inserted into the inner bore, wherein the inner rubber portion has a thickness that is smaller than a thickness of the outer rubber portion, wherein the inner rubber portion is not elastically-deformed by a load applied thereto, wherein the two partition members are embedded in the bushing body such that the two partition members correspond to each other in a vertical direction in a state where the stabilizer bar is inserted into the inner bore of the bushing body, wherein each of the two partition members includes opposite axial end portions that project in an axially outward direction beyond respective opposite axial end surfaces defined by axially outer faces of the respective opposite ridges, wherein, on at least one longitudinally extending edge of the opposite axial end portions of each of the two partition members, first and second outer flanges which extend in respective opposite radially outward directions of the semi-tubular shape of each of the two partition members, with respect to a cross section taken in a plane perpendicular to a longitudinal axis of the bushing body, are integrally formed with the respective partition members, and wherein each of the two partition members includes at least one through hole each located such that each of the two partition members is equally divided by a position of each of the at least one through hole in a circumferential direction and an axial direction thereof, the at least one through hole allowing unvulcanized rubber to pass therethrough at the time of injection molding of the elastic body.
