A ball joint has a ball seat fitted in a through hole of a socket. A recessed part of the socket has the same diameter as a receiving part of the ball seat. An attaching part of a dust cover is clamped into the recess formed by the recessed part and the receiving part to seal the interior of the ball joint from the entry of moisture and dirt, and to provide lateral support to the ball seat. A double-ended version is disclosed wherein attaching parts of two dust covers seal and provide lateral support to opposed ends of the ball seat. |
