This invention provides a spring which may be used to seismically support a movable shaft. The spring comprises an outer mounting ring and a concentric inner mounting plate connected to each other by a plurality of links having outer and inner hinge sections, pairs of reinforcing flanges, and linking flanges. The plurality of equally spaced links projects into the mounting ring at equal angles. The outer hinge portions of the links connect the links to the mounting ring. A pair of reinforcing flanges increases the natural frequency of the spring. At the end of the reinforcing flanges are the inner hinge portions of the links connecting the links to the linking flanges; the linking flanges connect the links to the center mounting plates and are integral therewith. The reinforcing and linking flanges are in planes normal to the planes containing the center mounting plate, the links, and the ring insuring a rectilinear spring deflection characteristic.
