験機。In a testing machine that tests the degree of fatigue of a material by repeatedly applying a load to a test piece by transmitting vibrations generated in a direction perpendicular to the rotation axis to the test piece when an eccentric weight is rotated around the rotation axis, the eccentric weight A guide frame in which a weight is connected to a rotating shaft with its axis disposed in a direction coaxial with the rotation axis, and a weight is held movably in the axis direction of the guide frame and A moving weight that moves in the direction of the axis of the guide frame in response to centrifugal force generated by rotation, and is interposed between the guide frame and the moving weight, and always urges the moving weight towards the axis of rotation. When the elastic body and guide frame start rotating, the movable weight receives centrifugal force and gradually moves, gradually increasing the repeated load on the test piece, and after a certain period of time, it is set to reach a predetermined load value. A fatigue testing machine characterized by having a load amount adjustment mechanism.
