A ball joint (10) comprises a metallic stud bolt (11) having a male screw (21) on one end side thereof and a spread portion (25) on the other end side, a resin ball member (12) of synthetic resin having a spherical portion (35) covering the spread portion (25), and a ball seat (13) of synthetic resin having a spherical recess (40) in which the spherical portion (35) is fitted for relative rotation and rocking motion. A nut (22) is fitted on the male screw (21). A noncircular detent portion (28) including serrations or the like is formed on the outer peripheral surface of the spread portion (25). A flange portion (30) is formed integral with the stud bolt (11) on the intermediate portion thereof in the axial direction. The resin ball member (12) has a cylindrical portion (36) integral therewith, and a dust cover fixing projection (37) is formed integral with the cylindrical portion (36). An end portion (50) of a dust cover (14) is held between the projection (37) and the flange portion (30). <IMAGE> |
