PROBLEM TO BE SOLVED: To provide a high temperature testing device capable of measuring opening displacement of a test piece without being influenced by deformation of a jig or the test piece.SOLUTION: An opening displacement detection mechanism is provided with a pair of support shafts 51 disposed in a test piece 23, a reference plate 52, a movable plate 55, and a displacement detector 58. The support shafts 51 inserted in a hole part 47 and disposed in the test piece 23 are installed by the reference plate 52 where a rod member 54 is engaged and connected and by the movable plate 55 where a rod member 57 is engaged and connected. Between the rod member 54 and the rod member 57, a displacement detector 58 for detecting opening displacement of the test piece 23 by measuring a distance between the rod members 54 and 57 is provided. |
