PROBLEM TO BE SOLVED: To provide a biaxial tension test device which can accurately execute a biaxial tension test by minimizing a difference in amounts of shrinkage between a link member moving to a first axis direction and a link member moving to a second axis direction so that the difference can be ignored.SOLUTION: A biaxial tension test device comprises: a rotating plate 11; a rotary drive transmission member 15 which rotates the rotating plate 11 around a central axis O; four sliders 21 to 24 which can be moved in four directions, respectively; and four link members 31 to 34 of which one ends are connected with the rotating plate 11 in a rotatable manner and other ends are connected with the respective sliders. When the rotating plate 11 rotates around the central axis O, the respective sliders 21 to 24 are configured to move in the four directions in a retractable manner by the link members 31 to 34. Test specimens holding means 41 to 44 which hold a test specimen 1 are directly or indirectly attached to the sliders 21 to 24, respectively. |
