PROBLEM TO BE SOLVED: To sandwich plural specimens under the same pressure by a single suppressing plate by sticking a slightly hard elastic plate to a surface contacting with the specimens of the suppressing plate through a soft extensible-contractible intermediate member. SOLUTION: A sleeve 19 having a flange having a spline groove is fitted in and fixed to a central part of an upper horizontal lever 17, and a spline shaft 18 is fitted and pushed in a shaft hole of the sleeve 19 so as to be freely raised and lowered. On the lower end of the spline shaft 18, a suppressing plate 20 is installed through a coil spring 24 on a lower part of a seat plate additionally connected to a flange part of the sleeve 19. This suppressing plate 20 is formed by successively layering and forming a metallic base board 21, a sponge plate 22 and a slightly hard elastic plate 23 composed of urethane or rubber or the like. When specimens (a) are suppressed and sandwiched by the suppressing plate 20, the suppressing plate 20 is tightly brought into close contact with surfaces of the respective specimens (a) by elastic force of the elastic plate 23 and the sponge plate 22. By the constitution, they can be reliably held by excellently contacting with the surfaces of the respective specimens (a) in an optimal condition to sandwich the plural specimens (a) at once. |
