Jack with a leg (1) and a supporting arm (2) articulated together by an articulation (3), whereby the leg rests against the ground (5) by way of a foot (4) and the supporting arm is articulated by another articulation (18) at the other end of the supporting arm to a load-support plate (19), whereby the plate supports the vehicle as it is lifted by way of an innermost section (20) located preferably between the sill ridge (21) and the midline, and below the bottom (22), of the vehicle, and a has a bodywork catch (25) with a bent-up section (26), whereby the bent-up section comes to rest against the outside (23) of the sill (24) when the jack is used and is raised by a spring (28), and with adjusting arms (9 & 10) articulated to the leg, to the supporting arm, and to each other, constituting a parallelogram linkage, whereby one end (17) of the supporting arm projects beyond its articulation (7) to its associated adjusting arm (9), and with a threaded displacement shaft (12) connected at one end to an articulation (11) between the adjusting arms and at the other to the articulation (3) between the leg and the supporting arm, characterized in that a spring (28) is mounted on the adjusting arm (9) articulated to the supporting arm (2) and extends more or less in a straight line toward the adjusting arm's articulations (7 & 11) and beyond the arm, with one end supporting the bottom of the bodywork catch on the load-support plate.
