置した時に試験片１の取付部１ｂ、Ｉｃと対応する取付
孔等の取付部２１ｂ 、 ３． ｂが形成されている。In addition, the clamping plate portions 21, 3. There are support stands arranged at the same interval as the width of the test piece 1 and whose length reaches the center of the holding plate portions 2□, 31. a is formed, and when the test piece 1 is placed on the support stand 21a, 31a, a mounting part 21b such as a mounting hole corresponding to the mounting part 1b, Ic of the test piece 1, 3. b is formed.
また取付部２１ｂ、３１ｂの延長上には試験片取付用ボ
ルト等の逃げ孔２１Ｃ、３１ｃが形成されている。Escape holes 21C and 31c for test piece mounting bolts and the like are formed on extensions of the mounting portions 21b and 31b.
なお、上記取付具２，３は左右対称に形成されているの

支持台３１ａが形成された面とを対向させると共に試験
片１の取付部１ｂ側を取付具２の支持台２１ａ間に取付
部１ｃを取付具３の支持台３１ａの間に介在することが
できる。Note that since the fixtures 2 and 3 are formed symmetrically, the surface on which the support base 21a of the fixture 2 is formed is opposed to the surface on which the support base 31a of the fixture 3 is formed, and the test piece 1 The mounting part 1b side of the mounting part 1b can be interposed between the support base 21a of the fixture 2, and the mounting part 1c can be interposed between the support base 31a of the fixture 3.
従って、取付部１ｂを取付部２１ｂに、また取付部１ｃ
を取付部３□ｂに夫々ボルト等を利用して固定すること
によって、取付具２，３は試験片１を介して一体化され
る。Therefore, the mounting portion 1b is replaced with the mounting portion 21b, and the mounting portion 1c is
The fixtures 2 and 3 are integrated via the test piece 1 by fixing them to the mounting portion 3□b using bolts or the like, respectively.
この時取付具２，３の支持台２１ａと３１ａの端面は対
