PROBLEM TO BE SOLVED: To provide a shaft correcting device preventing distortion of rotating shafts due to a temperature difference between the inside and outside of an environmental vessel when a test is conducted while a sample installed within the environmental vessel is connected to one of the rotating shafts located inside the environmental vessel and to the other rotating shaft projecting into the environmental vessel from the outside. SOLUTION: The amounts of distortion of the rotating shafts located inside and outside the environmental vessel and connected to the sample are measured, and the temperatures of pedestals bearing the rotating shafts are adjusted according to the amounts of distortion. Temperatures inside and outside the environmental vessel are measured and the amounts of distortion are estimated from the difference between the temperatures to control the temperatures of the pedestals so as to prevent misalignment of the shafts.
