Abstract: A jack for a car includes a support column having a middle region and a lower end. A base is articulated at the lower end of the support column and pivotable about a first transverse axis. A support arm is articulated at the middle region of the support column and pivotable about a second transverse axis extending in a given direction. The support arm has a free end with bearing surfaces having a circular segmental cross section. A spindle drive is actuatable by a hand crank for adjusting the free end in height. A load receiver has an open-top channel extending parallel to the given direction for engaging a structural part of a car to be supporting on a jack from below. The load receiver has a lower surface with a bearing extension in the form of a spherical section. A calotte-shaped bearing shell is at least partly congruent with and disposed between the bearing surfaces and the bearing extension for tiltably supporting the load receiver on the bearing surfaces in the form of a ball-and-socket joint.
