ABSTRACT:
A vibration damping element for attaching a windshield wipers drive unit to an automobile. The element incorporates the assembly screws, in preassembled condition, and retains them in the assembly position on the respective vibration damping element by a detachment prevention portion. To a achieve reliable detachment prevention and to reduce the effort in preassembling the assembly screws, the opening of the vibration damping element is closed by an elastomeric diaphragm attached to the vibration damping element for producing the detachment prevention. The diaphragm has a central hole with a smaller inside diameter than the thread diameter of the assembly screw. Thus, the assembly screw is held captive on the vibration damping element by the edge of the central hole being clamped elastically on the threaded screw stem.
