A shift knob () for a gearshift lever () of an automatic transmission of a motor vehicle has a locking bar () guided axially in the gearshift lever () and a release button () which can be actuated manually for actuating the locking bar () in relation to the gearshift lever (). The release button () is arranged in the shift knob () at the top end of the gearshift lever (). The release button () is connected to the shift knob () by means of at least one lever arm () via a mounting site (). The length of the lever arm () of the release button () is selected such in relation to the path traveled by the release button () during the actuation that the release button () performs an essentially linear movement.

A ball joint and a work process for preparing such a ball joint are described, in which the housing is prepared in one piece by a sheet metal shaping process. An edge bead, which is used to close the housing by a cover, is prepared by material deformation on the outer circumference of the housing. A groove for receiving the sealing bellows, which groove is likewise located on the outer circumference of the housing, is formed during the shaping process, so that machining of the housing is not necessary.
