Force measurement cell

Abstract

A force measurement cell having a block-like mechanism unit includes a Roberval mechanism and a lever mechanism formed by cutting out a single piece of parent material. The Roberval mechanism has a fixed part and a movable part on which a measured force acts. A gapped part is formed on either the lever mechanism or the Roberval mechanism following the vertical direction orthogonal to the axial direction of the lever mechanism and the Roberval mechanism, respectively. In addition, a stopper for restricting displacement of either the lever mechanism or Roberval mechanism is fixed to the fixed part of the block-like mechanism unit facing opposite the gapped part with a prescribed gap opened in the axial direction of either the lever mechanism or the Roberval mechanism. Another embodiment, includes a recessed part sinking from a respective side surface of the block-like mechanism unit formed on both side surfaces.
