PURPOSE: To realize a simple and lightweight structure, wherein a support mount and a carry mount are relatively movably disposed and vertically supported by two spring elements, by arranging the two spring elements in series and separating them from each other by a shape-stable support plate.
CONSTITUTION: A support mount 3 and a carry mount 4 are coupled to each other by two integrally fixed spring elements 1, 2. The first spring element 1 is disposed so as to at least partially coaxially incorporate the second spring element 2 at a radial distance, and the two spring elements 1, 2 are fixed to one another by a shape-stable support plate 7 in the form of a cup. Then, in an unloaded state, a stop surface 7.1 of the support plate 7 is allowed to rest on a corresponding stop surface 4.1 of the carry mount 4, and when vibration with a small amplitude is inputted, attenuation is carried out by the effect of the serially disposed spring elements 1, 2. On the other hand, in bad condition running, the stop surface 7.1 is pressed to the stop surface 4.1 by a cylinder 8.1, whereby a spring stroke of the second spring element 2 is locked.
