<p>A ball joint 1 is made up of: a ball stud 2 having a spherical head 4 and stems 3, 3 projecting oppositely from the spherical head 4; a bearing 6 slidably receiving the spherical head 4 of the ball stud 2; a housing 8 having a housing body 8a holding the bearing 6 therein. The housing 8 has a substantially cylindrical shape. The housing 8 has a housing opening 9a through which the one stem 3 of the ball stud 2 projects, and a housing opening 9b through which the other stem 3 of the ball stud 2 projects. Dust covers 14, 14 are fitted between the stems 3, 3 of the ball stud 2 and the housing 8, respectively. The dust cover 14 comprises a reduced open end 15 fitted on the stem 3 of the ball stud 2, and an enlarged open end 16 fitted in the opening 9a or 9b of the housing 8. A reinforcing ring 17 is embedded in the enlarged open end 16 of the dust cover 14. The reinforcing ring 17 consists of: a straight portion 17a which is substantially parallel with the axis of the enlarged open end 16; and a bent portion 17b which flares from an end of the straight portion 17a toward the outer circumference surface of the enlarged open end 16 at a sharp angle to the straight portion 17a. The dust cover is prevented from slipping out even when the ball stud is tilted. <IMAGE></p> |
