徴とする疲労試験機。 Upper and lower mounting jig assemblies that apply a uniaxial cyclic load to a vertically arranged test piece are connected to both ends of the test piece and have extended coaxial male threaded parts with barrels, and the upper and lower mounting jig assemblies In a fatigue testing machine equipped with a load system consisting of a fixed part to which the upper male threaded part of the jig assembly is screwed, and a movable part to which the lower male threaded part is screwed and moves in the axial direction by a drive device, both the upper and lower An annular member made of a material having a Young's modulus lower than the Young's modulus of the constituent material of the load system is inserted between each of the abutments between the body and the fixed part and the movable part, and the opposing surfaces of the upper and lower mounting jig assemblies are inserted. A fatigue testing machine characterized in that each of the cam rings is provided with a cam ring that abuts against the load in the compression direction and applies twisting force in the tightening direction to the upper and lower male threaded portions.
