A flexible diaphragm-like element that serves as a partition between the two chambers of a damping mechanism of a resilient motor mount. These chambers are filled with damping fluid, and their volume can be varied as a function of the springing movements of the resilient mounting elements, with the damping action deriving from the throttled transfer of the fluid from one chamber into the other. To prevent noise from being produced, the diaphragm-like element is secured in such a way that it has freedom of movement. This freedom of movement is set in the diaphragm-like element itself by dividing the latter into three concentrically disposed and interconnected ringshaped zones, namely a radially inner zone, a central zone, and a radially outer zone, with the thickness of the central zone being considerably less than the thickness of the inner and outer zones. The limitation of the freedom of movement is brought about by forming on both sides of the central zone projections in the form of a post configuration including cylindrical projections as well as cylindrical projections having axially continuous side ribs or beads and prism-like and/or post-like shapes with multiple corners.
