PROBLEM TO BE SOLVED: To provide a fatigue testing device which can achieve the improvement of measurement accuracy of a fatigue test by suppressing the slipping occurring to a grip part when the fatigue test is conducted by using a tabular test piece under high temperature.SOLUTION: A fatigue testing device includes: a fixture 30 which has a recess 35 engaging with at least one of a first grip part 121 and a second grip part 122 to be applied to a test object 100; and a spacer 90 which is provided in a gap formed between the recess 35 and the test object 100 and which thermally expands under high temperature so as to fill the gap. |
