PURPOSE:To always enable measurement with a high accuracy and a high sensitivity, by detecting displacement of a pair of opposed levers following the displacement of a test piece with a non-contact type displacement detection sensor. CONSTITUTION:A pair of opposed levers 1 made up of U-shaped displacement detection frames is arranged integral with a connection 2 having a thin elastically deforming part 3 at the center thereof. Following the displacement of the lever 1 and a test piece P, a non-contact type sensor 4 detects a follow-up displacement as displacement of the test piece P. With such an arrangement, elastic deformation of the displacement detection frames can be set as desired thereby always enabling highly accurate measurement without adversely affecting measuring accuracy of a load and displacement regardless of a reduction in the reaction of the lever. In addition, proper selection of sensors prevents the lowering of measuring sensitivity even when the elasticity of the displacement detection frames lowers in a high-temperature atmosphere.
