A rotational ball joint of a stabilizer for a vehicle is provided to improve the durability and prevent the twist of a dust cover by individually rotating a ball stud for the dust cover. A rotational ball joint of a stabilizer for a vehicle comprises a ball stud(2), a case(3), a bearing(7), and an airtight member. The ball stud has a rod assembled to two ends of a stabilizer(Sb) from a portion of a sub frame(S). The case loads a spherical ball freely rotated at the end of the ball stud. The bearing supports the spherical ball to prevent resistance for the portion of the spherical ball in the ball stud rotated by the external force inside the case whose lower portion is sealed by inserting a cap(4). The airtight member maintains the airtightness for the portion of the ball in the ball stud placed inside the case, to rotate the ball stud at the portion of a nut flange which is extended from the ball to be protruded to the outside of the case. |
