Abstract

A spring plate, especially for a MacPherson strut unit, having an axial support surface for the final turn of a helical spring. The helical spring is centered by radial centering surfaces in the area of the circumferential contour of the final turn. The centering surface is divided into individual, partial centering surfaces, which come to rest against the circumferential contour of the helical spring.
