PURPOSE:To detect the extent of deflection with high precision by guiding detection rods which are arranged in parallel to a bending load shaft relatively to a main body in a lengthwise movable state and pressing them against a body to be tested by the elasticity of an elastic means provided between the main body and detection rod. CONSTITUTION:The detection rods 11a and 11b are arranged in parallel to the bending load shaft Y and moved lengthwise to follow up the body 1 to be tested accurately. Further, coil springs 24a and 24b press upper ends of the detection rods 12a and 12b against a fulcrum roller 3R through a ball 28 and a detection jig 27 and the upper ends follow up the fulcrum roller 3R. Thus, the extent of deflection of the body to be tested is obtained with high precision. |
