の衝撃疲労試験機。[Claims for Utility Model Registration] 1. A testing machine shaft, which has a stopper attached to one end and which is connected to a fixed part through a test piece, is inserted into a movable tube, and the movable tube collides with the stopper by a drive mechanism. In an impact fatigue testing machine in which a collision load is propagated to the test piece, a fixed cylinder is arranged around the outer circumference of the movable tube to enable relative movement of the movable tube, and the outer circumference of the movable tube is A piston that is movable within the cylinder is attached to the cylinder, and by supplying fluid pressure to the cylinder, the piston and the movable tube can be moved toward the test piece, and a disc spring that opposes the movement of the movable tube is fixed. An impact fatigue testing machine characterized by being interposed between a member and a movable tube. 2. The impact fatigue testing machine according to claim 1, wherein the gap between the stopper and the movable tube is adjustable.
