A structural pivot 10 includes a first sleeve 18 and a second sleeve 20 which are connected together by a pair of flexures 22 and 24. Each flexure includes a pair of blades 40, 42 and 54, 56. The free ends of the blades are connected to the sleeves 18, 20 while the common cross members 44 and 62 remain spaced from the inner surfaces of the sleeves. During angular rotation of the sleeves, the blades can flex without resulting in a geometric center shift for the pivot.
