Abstract: A thrust device, in particular for a roller cam mechanism in a steering system, includes a first mechanism member which is held on a frame in engagement with a second mechanism member. The thrust device comprises a pressure piece which is mounted on the frame so as to be displaceable along an axis and is acted on by a spring element for pressing the first and second mechanism members against one another. In order to construct the thrust device for compensating for wear and thermal expansion of the engagement of the mechanism members and to configure it to be inexpensive and quiet during operation, there is provision for the spring element to be formed from rolling bodies which are spring loaded approximately transversely with respect to the axis of the pressure piece, the rolling bodies being supported on oblique surfaces between the pressure piece and a frame part which is configured as a setting screw or cover. The pressure piece can additionally be spring loaded axially by a compression spring.
