A method of manufacturing a flexural pivot device comprising the sequential steps of forming a cylindrical housing, forming a plurality of resilient members, inserting the resilient members within the housing and securing the resilient members thereto, milling (such as by electrochemical or electrical discharge means) two diagonally-opposite arcuate annular spaces having radially-inward projections at each end of the housing thereby forming diametrically opposed and overlapping inwardly-projecting arcuate structure, and cutting a circumferential groove in the housing coincident with the overlapping arcuate structure so that limited relative rotation of one arcuate structure relative to the other may occur upon flexing of the resilient means.
