ABSTRACT:
A vehicle jack of the type known as "Y-jacks". It has a base plate (1) with perforated fins that receive and fix, in a particular way, the protruding necks on the wings of the jack body. A nut (13) is secured to the end of the body, with easy entrance into the end and fixed by some lugs (14) which are bent over the central portion of the nut. The arm (3) of jack also has two protruding necks towards the interior, on which a cross member is received, formed by a part with a U-shaped section whose wings or sides clasp on to the necks, are made with U-shaped openings. The base of the cross member is controlled by a special easy entrance holder plate on the housing on the arm. An arm (30) of a specially designed shape acts in combination with a holder plate-cross member, whose seating for the vehicle has a metal insert. This holder plate-cross member is provided with an external retainer on which the end of the screw spindle is supported. These features eliminate conventional parts and provide for fast efficient assemble of the different components.
