Patent ID: 8672303

Claim:
A stabilizer-vibration-isolating bush for isolating a stabilizer in a vehicle suspension from vibration, the bush being adapted to be inserted from an open end of an axle beam having a substantially U-shaped cross-section and extending in a vehicle width direction and to be engaged with a stabilizer bar passing through inside the axle beam, wherein the stabilizer-vibration-isolating bush comprises a tubular elastic element which has an opening for engaging with the stabilizer bar and a fitting hole being in communication with the opening and adapted to be fitted over the stabilizer bar, the opening has a pair of first projections and a pair of second projections in a range from the fitting hole to an open end of the opening, the first projections are positioned adjacent to the fitting hole and face each other, and the second projections are positioned adjacent to the open end of the opening and face each other, wherein the pair of first projections and the pair of second projections do not make contact with each other when the opening engages with the stabilizer bar, and the pair of first projections and the pair of second projections are formed so as to make contact with each other in a direction of extraction of the stabilizer bar when there is generated a force in a direction in which the fitting hole is extracted from the stabilizer bar, and wherein the first projections and the second projections are provided by a pair of grooves being formed in a pair of mutually opposing opening surfaces for constituting the opening, and the grooves are formed into a V-shaped cross-section.
