Abstract A spring element of the type comprising two metal plates and an elastic rubber body therebetween is provided wherein, instead of the rubber body filling all the space between the metal plates, this body is so constructed that it gradually fills the space as the plates are compressed. The rubber body is thicker at the center than at the perimeter and when round, is substantially of the shape of a discus. The plates have corresponding depressions in the central part, so that they can be stacked one on the other with the depressions serving to align the separate elements. Preferably, the rubber body is cemented or otherwise secured to the plates only in the central part, i.e., at the axis of the body or the corresponding depression or projection in the plates.
