ABSTRACT:
A vehicle jack that provides a rotation shaft (4) for the support plate (3) on the vehicle support arm (2) and a nut to be received in the end of the jack support leg (1), through which the screw-threaded spindle shaft passes. The rotation shaft (4) rests on and passes through sets of holes in the vehicle support arm (2) and the support plate has downwardly projecting side fins (6), through which the said shaft also passes. The nut (12) determines a set of diametrically opposed projections (22) with an irregular outer surface, through which it is fixed to the holes (16, 18) cut in the side end wings of the vehicle support arm.
