Abstract
A ball joint for use in motor vehicles comprises a bearing member (7) made of a plastic material and disposed between a joint housing (1) made of a plastic material and a ball head (3). The bearing member has projections (10) on its outer surface that engage undercuts (11) on the inner wall of the joint housing. The joint housing (1) is simple to produce. The bearing member (7) is prevented from rotation with the ball head. To this end, the undercuts (11) are formed as circumferentially extending boundary walls of axially extending grooves (13) which open at one end (14) of the joint housing (1). The projections (10) on the outer surface of the bearing member (7) engage the circumferentially extending boundary walls of the grooves (13) and the radially extending side walls thereof.
