Abstract: A shaft includes a main refrigerant passage capable of supplying a refrigerant in one direction on an axial center part and a test piece side sub-refrigerant passage having a starting end communicating with the vicinity of a downstream end in a refrigerant supply direction of the main refrigerant passage. The downstream end in the refrigerant supply direction of the main refrigerant passage is set at the position before an end of the shaft at the side to which a test piece is connected and a predetermined position on the downstream side in the refrigerant supply direction relative to a test piece side bearing. An ending end (discharge port) of the test piece side sub-refrigerant passage is set on the upstream side (counter test piece side) in the refrigerant supply direction relative to the test piece side bearing.
