A pillow ball bush having an axial clearance is provided to improve the steering efficiency by improving the insulation efficiency to an forward and rearward impact and increasing the transverse strength. A pillow ball bush includes a pillow ball shaft(2), a ball seat(3), a rubber mass(6), an outer case(9), a cap(10), and a dust cover(11). The pillow ball shaft is hollow and a spherical ball is formed in the pillow shaft. The ball seat surrounds the ball not to form a radial clearance. The rubber mass is located on both side surfaces of the ball seat to produce an axial displacement of the pillow ball shaft. Both ends of the pillow ball shaft is exposed. The outer case accommodates the ball seat and the rubber mass. The cap is inserted into one side surface of the outer case to restrict the internal position by pressing the rubber mass axially. The dust cover surrounds the protruded cap portion and a sealed fixing end to form a seal of the interior of the outer case. |
