Abstract: A cylindrical rubber elastic member for having a stabilizer bar inserted therein comprises an inner layer rubber with high sliding properties and an outer layer rubber provided outside of the inner layer rubber. Both the stability in operation and the riding comfort can be improved. Further, the rubber elastic member comprises a sliding surface made of a rubber with high sliding properties at the end face thereof. Frictional resistance can be lowered to prevent abnormal noise. A stabilizer bushing comprising a main body rubber portion of a sulfur-vulcanizable first rubber compound and a sliding rubber portion of a second rubber compound containing a sulfur-vulcanizable lubricant on the inner surface of the main body rubber portion, wherein the first rubber compound exhibits vulcanizability satisfying: t90−t50 ≧1.
