PURPOSE: A fatigue testing apparatus is provided to improve accuracy and reliability in a bending fatigue test on a plate type specimen through a simple mechanism. CONSTITUTION: A fatigue testing apparatus (100) includes a vibration generator (110), a power generator, a specimen jig part (130), and a contact maintaining part (150). The vibration generator applies vibration to a plate type specimen in the thickness direction of the specimen. The power generator supplies power for driving the vibration generator. The specimen jig part clamps the specimen, and is capable of approaching or being separated from the vibration tip of the vibration generator. The contact maintaining part applies a force on the specimen jig part toward the vibration tip so that the vibration tip is maintained to be in contact with one side of the specimen when the vibration generator is actuated. |
