Abstract
By using a second Roberval mechanism having beams orthogonal to beams of a first Roberval mechanism for supporting a weighing dish by a movable pillar and integrating a movable pillar of the second Roberval mechanism with a movable pillar of the first Roberval mechanism, longitudinal and crosswise one-sided loads are shouldered by first and second Roberval mechanisms and. Furthermore, by forming flexible portions flexible for one-sided loads (right and left one-sided loads) about the axis of the first Roberval mechanism on the first Roberval mechanism, torsions due to one-sided loads in the crosswise directions are prevented and influences of the torsions can be reduced. Moreover, by forming flexible portions flexible for a longitudinal one-sided load on the second Roberval mechanism, a torsion due to the longitudinal one-sided load is prevented and influences of the torsion can be reduced.
