置。[Claims for Utility Model Registration] In a repetitive bending test device that performs a test by applying forward and reverse rocking motion at an arbitrary angle with the approximately central part of a test piece made of a thin steel plate as the bending point, a sound collecting means placed close to the sound collecting means; and an amplification device connected to the sound collecting means to amplify the sound generated at the bending point. A filter means for selectively transmitting only the sound corresponding to the crack sound generated in the test piece from the sound obtained from the amplifier, and a display device for displaying the transmitted signal from the filter means. Characteristic repetitive bending test equipment.
