PROBLEM TO BE SOLVED: To provide a strength tester capable of changing a load optionally based on a weight load system for amplifying a load through a lever in order to maintain a tensile/compressive load stably for long hours. SOLUTION: In a tension/compression tester, the lever 20 is constituted of three points, namely, a fulcrum, a load application point, and a load point where a weight is applied; and a structure is applied, wherein the weight is moved forward and backward by a motor 2 and a ball screw 24 means in order that a fixed weight load becomes continuous and its velocity becomes variable, and that the fulcrum can be moved continuously on the lever; and the load applied to the load application point can be controlled by changing motor speed optionally.
