ABSTRACT:
A ball joint including a housing having two inner chambers in which spherical head portions of ball studs are housed so that the ball studs are swingable, and ball seats interposed between the spherical head portions and the inner chamber walls. The housing is integrally formed of a synthetic resin.
The cross-sectional centroid of a central portion of the housing and the cross-sectional centroid of a portion of the housing in the vicinity of each inner chamber are set on the opposite sides of a axial line connecting the two spherical head portions.
Annular recesses are formed in the outer circumferential surfaces of the housing, and end flanges of dust covers each having an extreme end portion smaller in contact area in comparison with its base end are engaged with the annular recesses.
