摘要：
A steering box for a motor vehicle comprises a rotatable toothed pinion, an axially movable rack within a casing, and a support unit to support the thrust which the pinion applies to the rack during operation. The support unit comprises a rotatable roller operable to support the rack. The roller is provided with an axial hold in which is formed a pair of rolling tracks for rolling bodies. A pair of rings are disposed within the hole in contact with one another, each forming with the roller the rolling tracks for the rolling bodies. Two rings of the rolling bodies are disposed between the roller and the rings. A pin supports the rings. The pin is mounted in a cylindrical body provided with a central cavity operable to house the roller, at least patially. The cylindrical body is provided with a pair of slots each of which is able to receive one end of the pin.
