Claim Text:
1. A spindle drive for an adjusting element of a motor vehicle comprising a drive motor with a spindle-spindle nut gear arranged downstream for producing a drive force along a geometric spindle axis, wherein two connectors are provided for transferring the drive force and wherein at least one connector comprises a ball joint with a ball socket and an assigned ball, wherein the ball socket comprises a ball socket housing with a connecting piece, wherein the ball socket in the ball socket housing has a damping shell and a bearing shell in the damping shell for the positive engagement with the ball so that the flux of force for the drive force passes via the damping shell and the bearing shell, wherein the bearing shell is assigned a plurality of retaining elements for retaining the ball in the bearing shell, the plurality of retaining elements being arranged over the periphery of the ball, wherein the plurality of retaining elements are able to be deflected out of a retaining position such that the ball is able to be inserted into the bearing shell by deflecting the plurality of retaining elements, and wherein the plurality of retaining elements is designed and arranged such that a deflection of the plurality of retaining elements is associated with resilient deformation of the damping shell.
