A compression test is performed in the same manner as described above by making diagonal contact with the side rail. In addition, when performing a test by rotating the support arm 6 around its axis O in FIG. After that, a compressive load may be applied to the test specimen using the hydraulic cylinder 21 in the same manner as described above.
