PROBLEM TO BE SOLVED: To provide a thermal fatigue testing device that can check the thermal fatigue behavior of a rotary member in fluid with complicated temperature fluctuation. SOLUTION: The thermal fatigue testing device is composed of a rotary test piece, a fluid container for retaining fluid around the rotary test piece, a driving part for rotating the rotary test piece, a fluid supply system for supplying the fluid with different temperature, a device for controlling positioning in the rotary direction of the rotary test piece, and a control part for controlling a thermal fatigue test, thus carrying out the thermal fatigue test where high- cycle thermal fatigue is combined with low-cycle one.
