Seat members (31) are held while being movable relative to first slide members (21) or second slide members (22). Rotating screws (39) in the direction in which the distance (d) between a surface (A) of each of the first slide members (21) or of each of the second slide members (22) and a surface (B) of one of the seat members (31) increases moves chucks (25) in the direction in which the distance between the chucks (25) increases, thereby applying pre-tension to a testpiece. When play (backlash) in a system for transmitting force from a support section to each of the chucks (25) is eliminated, a biaxial tensile test is started. |
