PROBLEM TO BE SOLVED: To make a jig structure simple.SOLUTION: A tensile test fixture I comprises: a first load transmission member 5 provided with a pair of engagement portions 8 and 8 disposed with a gap 9 interposed therebetween at a leading end portion; a lever 6 disposed at positions with the gap 9 interposed therebetween on a leading end surface of the first load transmission member 5 in such a way as to oppose each other; and a second load transmission member 7 that is arranged so as to bring a leading end into contact with the lever 6 and is provided with a space portion 13 capable of accommodating a grip portion 3b of the other end side of a tensile test piece 1 at a central portion. When a tensile test is performed, a tensile load is applied to a gauge portion 2 of the tensile test piece 1 by causing the pair of engagement portions 8 and 8 of the first load transmission member 5 to engage with a grip portion 3a of one end side and by transmitting a load obtained by reversing a direction of a load imparted by the second load transmission member 7 to the grip portion 3b of the other end side of the tensile test piece 1 with the gauge portion 2 accommodated in the gap 9 by using the lever 6. |
