Abstract
Protruding part of a mechanism body is connected to a base frame by screws, and other protruding part is connected to an auxiliary connecting metal fittings by the screws. A machining necessary for connecting is conducted on the protruding portions, the widths of which are wide. Therefore, a sufficiently long distance can be obtained by the protruding portions. As a result, the Roberval's parts 4, 5 are not affected by stress strain, which is caused in the process of connecting, even if a size of an electronic balance in a longitudinal direction is not extended. Accordingly, it is possible to realize the compact electronic balance of high performance in which an accurate measurement can be made even if a load is given to a balance pan being biased.
