  • Publication number: 20080034911
    Abstract: In a device for pressing a steering rack against a pinion, having a thrust member and a setting element, it is provided that the thrust member and the setting element each have contact faces aligned with one another which, in a basic position, abut against each other, at least one of the contact faces being flexible. The thrust member has a thrust-member body and a pin which projects in the direction of the setting element and whose exposed end takes the form of a contact face. The setting element has at least a two-part configuration, made up of an adjusting screw and a spring washer. The spring washer is disposed between the adjusting screw and the thrust member, and forms the contact face for the exposed end of the pin.
