Abstract

There is disclosed an actuating lever for a car jack having a rotating element driving the lifting movement of the car. The lever comprises a ratchet mechanism with a toothed wheel (5) having a central polygonal opening (6) for insertion of the rotating jack element. At least the toothed wheel is made of a pressed metal material. The ratchet mechanism is contained within a housing constituted by two half-shells (1, 2) made of plastic or thin plate. <IMAGE>
