Abstract

A balance with a system carrier (1) fixed to the housing and with a balance-scale support part (2) connected by two upper and two lower guide rod struts in the form of a parallel guide to the system carrier. Each upper guide rod strut is connected to a lower guide rod strut via two connection areas, which struts are combined to a guide rod plate (5,6). The two guide rod plates (5,6) are fastened laterally to the system carrier (1) and to the balance-scale support part (2). The system carrier (1) is wider than the balance-scale support part (2). The two screw attachment surfaces for the guide rod plates (5,6) on the system carrier (1) and on the balance-scale support part (2) form an angle with one another so that the system carrier (1), the two guide rod plates (5,6) and the balance-scale support part (2) form a trapezoid when viewed from the top.
