The proof body for a weighing apparatus is comprised of a profiled segment and it includes a measuring beam (9) joined at each one of its ends to a respective wing (10a, 10b) which extend substantially perpendicularly to the measuring beam (9) and of which the free side faces (11a, 11b) provide abutment faces. It further includes an abutment beam (13) which is parallel to the measuring beam (9) and which is connected thereto via two ribs (14), this abutment beam (13) being also connected to each one of the wings (10a, 10b) by a web (15) which is substantially parallel to the measuring beam (9). Under such circumstances, a strain gauge (18) affixed beneath the measuring beam (9) is subjected only to contraction strains when a force is applied beneath the abutment beam (13).
