1. A vibration absorber for absorbing and/or damping vibrations of a vehicle part, comprising: at least one mass element, at least one fastening element for fastening the vibration absorber to the vehicle part, at least one spring device and a first securing device which captively connects the mass element and the fastening element to one another, wherein the spring device comprises two elastomeric shaped parts manufactured separately from the mass element and the fastening element; wherein the first securing device receives the elastomeric shaped parts to form a first elastic mount unit which elastically decouples the mass element from the fastening element; wherein the first securing device comprises a bolt which extends together with the elastomeric shaped parts through an opening of the fastening element, the bolt connected to the mass element; wherein the first securing device has a collar that abuts against the spring device, the collar is configured as a stop on the fastening element, and the bolt does not extend through the collar; wherein each of the elastomeric shaped parts has a circumferentially extending edge section which is inserted into the opening of the fastening element, and the edge sections are in contact within the opening; and wherein the vibration absorber further includes a second elastic mount unit having a second securing device, the first securing device holds a different number of elastomeric shaped parts than the second securing device.
