Abstract: A ball joint includes: a ball stud including a stud portion having one end portion connected to a structural member and another end portion, to which a ball portion is integrally joined; a housing made of metal and configured to support the ball portion to allow swinging and rotating movement of the ball portion; and a ball seat made of plastic and interposed between the housing and the ball portion. The ball seat includes a plurality of protrusions jutting out from the ball seat and inserted into a plurality of through holes formed in a bottom portion of the housing. The protrusions having pierced through the through holes are staked at their distal portions. The protrusion of the ball seat has a large diameter portion, whose diameter is larger than an inner diameter of the through hole, at its proximal portion proximal from the distal portion thereof.

Abstract: A stabilizer link includes a support bar and a ball joint. The ball joint includes a ball stud having a ball portion and a stud portion. The stabilizer has two end portions, each of which includes an attachment portion for joining the stabilizer link. The attachment portion has a through hole, through which an elastic member provided at the stud portion is attached to the attachment portion. The elastic member includes a body portion and tab portions. The stud portion is joined to the attachment portion through the elastic member in such a manner that while the elastic member is attached to the through hole, the body portion abuts on an inner circumferential wall portion of the through hole and the tab portions are located to cover circumferential edge portions of the through hole.

Abstract: A hollow stabilizer (1) according to the invention is formed in a hollow shape and includes a bent portion (1c1, 1c2, m1-m5). With a thickness of an inner side of the bent portion (1c1, 1c2, m1-m5) being larger than a thickness of an outer side of the bent portion (1c1, 1c2, m1-m5), a hardness of the outer side of the bent portion (1c1, 1c2, m1-m5) is higher than a hardness of the inner side of the bent portion (1c1, 1c2, m1-m5) through quenching by cooling down after heating by electrical heating.
