A flexion rod (1) has two through holes (2 3), connected together by a hollow portion (4). Four weakened portions (5, 6, 7, 8) are thus formed in the rod (1). A quadruple strain gauge (9) is fixed to the rod (1) at a right angle with one (5) of said weakened portions, and in order to correct the inaccuracy of the measurements resulting from the presence of the quadruple strain gauge (9) at only one location of the rod (1), two calibrated notches (10, 11) are provided at a right angle with other weakened portions (7 8).
