Abstract
The vehicle jack comprises a support having a base plate and a cap bordering together an interior space. The latter contains a bevel gear with a first gearwheel rotatable about a first, inclined axis and a second gearwheel rotatable about a second, vertical axis. The base plate and the second gearwheel comprise annular guiding and rolling surfaces guiding together a set of rolling bodies, viz. balls, so that the base plate, the second gearwheel and the rolling bodies form together a rolling bearing. The base plate and the gearwheels are formed of sheet metal members. The shapes of said annular guiding surfaces and of the teeth of the gearwheels are defined substantially by plastic, non-cutting shaping. The jack can be light and can be manufactured and assembled at low costs.
