Claim:
A vibration damper for a rotatable tubular propeller shaft in the drive train of a motor vehicle, the vibration damper comprising: a sleeve arranged in the shaft and rotatable with the shaft, the sleeve defining a radial and circumferential direction; a mass body mounted concentrically in the sleeve; a plurality of rubber spring elements for mounting the mass body to the sleeve; and a plurality of flexible stop elements, each flexible stop element disposed circumferentially between adjacent spring elements and disposed between the mass body and the sleeve to define a discrete space to limit a vibration travel of the mass body at least in the radial direction, wherein a contact surface of each stop element extends over a larger circumferential angle than the spring elements and than between an area between each stop element and each adjacent rubber spring element, such that each stop element occupies a large portion of a space between the mass body, the spring elements and the sleeve.
