Abstract
A ball-and-socket joint used in a linkage mechanism of the motor vehicle steering device has a ball head of a shank, encompassed by a bearing in a housing. The housing has an end opening at the opposite side of the shank. A joining member made up of a head part and a male screw portion is fitted in the opening at the head part. The head part is integrally formed with a peripheral flange, preferably a flange of flared shape. The surface of the flange is covered with an elastic layer. A fixing ring abuts against the flange to prevent detachment of the joining member from the housing. A closure plate may be interposed between the flange and the bearing and between the flange and the housing. Vibration and shocks imparted to the ball head through the shank is absorbed by the elastic layer without increasing the diametrical dimension of the joint.
