    • PROBLEM TO BE SOLVED: To provide a ball joint capable of gradually increasing a rotational torque according to an increase in rotational angle by elastically deforming a ball seat in a rotational direction in the early stage of rotation when a ball stud rotates on its axis center. SOLUTION: The frictional engagement force between a globular head 11a of a ball stud 11 and a ball seat 12 is set larger than the frictional engagement force between the ball seat 12 and a socket 13, at the part provided with a slit S of the ball seat 12. So, the ball seat 12 elastically deforms in a rotational direction before the globular head 11a begins to slip on the ball seat 12, at the part of large frictional engagement force during rotation on the axis center L of the ball stud 11.

    • In a ball joint 10, when a ball stud 11 rotates about its center axis L, at the beginning of the rotation, a ball seat 12 can be elastically deformed in the rotational direction, whereby the rotational torque can be gradually increased as the rotational angle increases. In a region of the ball seat 12 where slits S are provided, the frictional engagement force between a spherical head portion 11 a of the ball stud 11 and the ball seat 12 is made grater than the frictional engagement force between the ball seat 12 and the ball socket 13. Therefore, when the ball stud 11 rotates about its center axis L, the ball seat 12 elastically deforms in the rotational direction before the spherical head portion 11 a starts to slip in relation to the ball seat 12 in the region where a lager fiction engagement force is generated.
