A structural pivot 10 includes a first sleeve 18 and a second sleeve 20 which are connected by a pair of parallelogram shaped flexible elements 22 and 24. The flexible elements include tapered ends 40, 42 and 44, 46, respectively. The tapered ends of the flexible elements are connected to sleeves 18, 20 so that the flexible elements 22, 24 are assembled in a crisscross fashion while the flexible elements remain spaced from each other. During angular rotaton of the sleeves, the flexible elements undergo both flexural and torsional action.
