Abstract:
A holding ring for the axial fixing of a rotary bearing of a steering apparatus for motor vehicles on a rotatable component with a cylindrical outer surface onto which an inner bearing shell of the rotary bearing is mounted, wherein the holding ring includes at least one spring tongue which lies in an axial direction resiliently against the inner bearing shell, is improved with regard to a simple design and assembly process in that the holding ring comprises radially inwardly projecting elastic fixing tongues which, in the relaxed state, extend into the radial region of the rotatable component such that, when the holding ring is pushed onto the cylindrical outer surface of the rotatable component, the fixing tongues are deflected elastically in an axial direction opposite to the pushing-on direction and lie with a radial preload force against the outer surface of the rotatable component.
