Abstract: A support structure having a beam portion (2) undergoing bending when the load is imposed on the support structure and a separate elastic member (1a) which deforms elastically in a manner inversely proportional to beam bending from the middle of the support structure towards its ends so that the sum of the deformation produced by beam bending and the deformation of the elastic member is constant, whereby a longitudinal support line in the support structure remains as a straight line even though the support structure itself yields in the direction of the force.
