A preloading device for a piston valve of a vibration damper includes a spring element which is fitted by an inner diameter onto a radially inner centering device which serves for inner centering of the spring element in the installed state of the preloading device. To provide a preloading device for a piston valve by which a reliable inner centering of a spring element can be ensured but which can be placed with low expenditure on assembly at the same time, the spring element is axially fixed at the centering device via retaining means in that the retaining means at least partially enclose the spring element axially on both sides and are rigidly connected to the centering device in each instance.
