PROBLEM TO BE SOLVED: To provide a tensile test jig capable of preventing an optical fiber from being broken in performing a tensile test.SOLUTION: In a tensile test jig, a restraint member 3 comprises: a pair of first members 31a and 31b one ends of which are connected to a first fixing part 1; a pair of second members 32a and 32b one ends of which are connected to a second fixing part 2; and a pair of coupling parts 33 for coupling the other ends of the pair of first members 31a and 31b and the pair of second members 32a and 32b, respectively. The restraint member 3 attached to the first fixing part 1 and the second fixing part 2 supports the first fixing part 1 and the second fixing part 2 so as to maintain an interval between the first fixing part 1 and the second fixing part 2 by rigidity of the restraint member 3. |
