Zusammenfassung:PROBLEM TO BE SOLVED: To provide a fretting fatigue testing fixture capable of evaluating fretting fatigue strength easily and at a low cost by arbitrarily changing a relative slip quantity against load stress, a fretting fatigue testing apparatus equipped with the fretting fatigue testing fixture and a fretting fatigue evaluation method.SOLUTION: There are provided fretting fatigue testing fixtures 20a and 20b for attaching a specimen 50 on a fretting fatigue testing apparatus 1 for evaluating a fatigue due to a relative slip. The fretting fatigue testing fixtures 20a and 20b comprises: at least one of contact parts 22a and 22b which are disposed so as to press the specimen 50 and support relatively slidably the specimen on the boundary contacting with the specimen 50; and elastic bodies 21a and 21b for imparting displacement according to load stress to the contact parts in the relative slip direction.
