Abstract: A tensile test machine which has a simple structure and which can measure the strength of a sample having a minute tensile strength is provided. The tensile test machine 100 has a first gripping member 117 and a second gripping member 125 which oppose each other in the horizontal direction and grip two end portions of a sample WK. The first gripping member 117 is supported by a moment receiving member 113a of a torque meter 113 through a first support beam 116 and a tensile force transmitting member 115. The tensile force transmitting member 115 is formed so as to extend in the radial direction of the moment receiving member 113a. The second gripping member 125 is supported by a displacement table 121 through a second support beam 124 and a gripping member support base 123. It is displaced in the direction away from the first gripping member 117, and the amount of displacement is measured by a displacement measuring device 128.
