ABSTRACT:
In a force-transmitting device of a force-measuring cell with a parallel-guiding mechanism in which a stationary parallelogram leg and a movably guided parallelogram leg are connected to each other by parallelogram guides, at least one of the parallelogram legs has a fastening part with at least two fastening portions. Each fastening portion has a fastening pad with a tapped hole normal to the fastening pad surface, for fastening the device to a housing or a load carrier. The parallelogram leg has slot-shaped incisions that serve to uncouple the fastening portions from the rest of the parallelogram leg, so as to prevent the propagation of assembly stresses from the fastening portions into the working parts of the force-measuring cell.
