To provide a device capable of performing a tensile test into four directions along the orthogonal two axes and performing such tensile operation for four directions in synchronism with each other by one driving means.
A two axes tensile testing device comprises: a driving force transmission link 10 having four link members 6-9 whose ends are connected to be freely rotatable through connection axes 2-5; and connecting holders 11-14 arranged at each connection axis 2-5 of the driving force transmission link 10 respectively to be connected with respective connection parts 1A-1D of a test piece 1. The connection holder has two pairs of the first axis side connection holders and two pairs of the second axis side connection holders. The second axis side connection holders are connected with the connection holder axes which are arranged in the opposite side of this two axis side connection holders with respect to the test piece so as to sandwich the test piece.
