置。 In a fatigue test method in which a test piece consisting of a ring-shaped member is sandwiched between a pair of loading jigs and a compressive load is applied, the ratio of the wall thickness of the test piece to the radius of the center axis of the cross section is 0.1.
Using a test piece that is 5 or less or 1.2 or more,
Two small-diameter cylinders are rotatably arranged between the test piece and the loading jig at an interval determined depending on the outer diameter of the test piece, and the test is carried out by a loading roller through the small-diameter cylinders. A fatigue testing device for a ring-shaped member, which is characterized by applying a compressive load while rotating the piece.
