PURPOSE: A wire bending tester is provided to test bending to a wire of various diameters by preparing a vertical penetration hole of various inner diameters in a wire supporting hole and connecting an outer diameter with an identical adaptor bolt. CONSTITUTION: A wire is fixed between a wire fixing tool(28) and both grips so that a free end part of a separator(29) is leaned downward. In addition, a body of the separator keeps the movement state while pressing a spring. A lower end of the sire is extended to the lower part, passing through an insulation body(35) and is contacted with a casing(33). Two electric wires installed by putting the insulation body between the electric wires are connected each other. In this state, a driving motor(21) is driven by manipulating a driving switch, and the forward/reverse rotation of a bending arm(22) are accomplished. The wire as a test target is continuously given bending stress. Herein, the bending arm rotates forward/reverse at a rotation angle within 180 degrees, and is accomplished as a forward/reverse rotation sensor(31) senses a reversion sensing point of rotation direction.
