ミニウム材を使用することが増えてきた。[0003] In recent years, adverse effects on the environment of automobiles have become a problem, and efforts to improve fuel economy of automobiles have been actively made. Therefore, the demand for reducing the weight of automobile parts has increased, and the use of a soft and lightweight metal material, for example, an aluminum material for the housing 111 of the ball joint 101 has also increased.

化が充分に達成できないということがある。The use of the ball joint 101 having the housing 111 made of an aluminum material as described above certainly leads to a reduction in weight. However, since the aluminum material has lower strength than the steel material, when used for the housing 111 of the ball joint 101, the load received from the ball stud 102 may cause the housing 111 to be distorted and the ball stud 102 to rattle. . Therefore, it is conceivable to increase the thickness of the housing 111 in order to suppress rattling of the ball stud 102. However, when the thickness of the housing 111 is increased to increase the strength, the volume of the housing increases, and eventually, the weight of the ball joint may not be sufficiently reduced.

In a ball joint including a bearing and a housing that holds the bearing, the housing includes:
Since the outer cup made of a soft lightweight metal material and the inner cup made of a hard metal material arranged on the inner peripheral side of the outer cup, the main load applied from the ball stud is received by the hard metal inner cup, Since the load applied to the outer cup made of a lightweight metal material can be reduced, the weight is high and the strength is high, and the occurrence of rattling due to distortion of the housing can be suppressed.

耐荷重を高く設定できる。The housing has an inner peripheral abutment surface formed substantially perpendicularly to the axis on the inner periphery of the outer cup and an outer peripheral abutment surface abutting on the inner periphery abutment surface on the outer periphery of the inner cup. Then, since the load in the axial direction can be received by the inner peripheral abutting surface and the outer peripheral abutting surface, the axial load resistance can be set high.

The change in the directional dimension is reduced by the retaining ring at the end of the housing opening and the impact on the ball head of the ball stud is reduced by the retaining ring, and at the inner bottom end, it hardly affects the ball head of the ball stud. A swinging / rotating torque can be obtained.
