ABSTRACT:
A bushing for a vehicle suspension comprises an inner tube, an outer tube coaxially surrounding the inner tube, and a vibration isolating rubber filled between and integrally bonded to the inner and outer tubes. The inner tube has, on a part of its outer periphery, a hump portion projecting radially in a fan shape, which has an inclined surface. The outer tube has a tapered portion at one end, which is substantially identical in angle of inclination with the inclined surface of the inner tube hump portion and faces the inclined surface. A plurality of arcuate hollow portions are provided in the vibration isolating rubber to raise the compliance characteristic of the bushing in the longitudinal direction of the vehicle and thereby improve the riding comfort. Both the riding comfort and the steering stability are thereby improved.
