Abstract
A stabilizer bushing is provided which effectively reduces a torsional friction between a bushing body and a stabilizer bar. The stabilizer bushing includes a bushing bodymade of a tubular elastic body, a sliding memberfixed to an inner circumferential surface of the tubular elastic body, and two partition membersembedded in and bonded to a radially middle area of the bushing body. The partition membersdivide the bushing bodyinto an inner rubber portionthat is thin enough not to be elastically-deformed by a load applied thereto and an outer rubber portionthat is thicker than the inner rubber portion. Further, each of the partition membersincludes through holesthat are located so as to divide the partition member into a plurality of sections both in the axial and circumferential directions.
