TENSILE TESTING MACHINE

A tensile testing machine that has a simple structure ans is capable of carrying out strength measurement of a sample with very small tensile strength is provided. A tensile testing machine (100) is provided with a first grasping body (117) and a second grasping body (125) that face each other horizontally and grasp two ends of a sample (WK). The first grasping body (117) is supported by the moment receiving body (113a) of a torque meter (113) via a first supporting beam (116) and a tensile force transmitting body (115). The tensile force transmitting body (115) is formed so as to extend in the radial direction of the moment receiving body (113a). The second grasping body (125) is supported by a displacement table (121) via a second supporting beam (124) and a grasping body support base (123) and, as the second grasping body (125) is displaced in the direction away from the first grasping body (117), the displacement is measured by a displacement measuring device (128). An external computer (130) measures the tensile strength of the sample (WK) using the tensile force measured by the torque meter (113) and the displacement of the second grasping body (125) measured by the displacement measuring device (128).
