Abstract
An automotive jack in which an upright member is provided with a pivotable base plate hinged on a first pivot at the bottom of the upright member. This upright member has a second pivot on which a supporting arm is turnable. The supporting arm is pivoted by an actuating device. A spring pivots the base plate along the length of the upright member, and the supporting arm has, at one end, a load interception head for pivoting the base plate through a stop against the force of the spring into a position at an angle to the length of the upright member when the jack is folded together. The sole of the base plate has an entire surface butting against the ground for any extensions and loads of the jack due to the pivoting of the base plate about the first pivot.
