ABSTRACT:
A flexure or bending coupling member (10) is disclosed for precision scales and the like, including a pair of clamping end portions (12) joined with a central bar portion (18) via a pair of flexure portions (15), characterized in that the bar portion is arranged normal to the plane containing the end portions and the bending axes of the flexure portions. The central bar portion is connected with the flexure portions (15) via twisted portions (20) rotated 90.degree. about the longitudinal axis of the flexure coupling member, thereby affording improved resilience in the lateral direction and greater insensitivity regarding dimensional inaccuracies at the clamping locations and/or with respect to temperature variations.
