MINUTE MATERIAL TESTING APPARATUS

PROBLEM TO BE SOLVED: To provide a minute material testing apparatus capable of changing a minute test piece so as to precisely follow the change in an actuator. SOLUTION: The minute material testing apparatus is equipped with an arm (12); a first vibrating part (13) connected to one end of the arm and having a first elastic part (15) producing the restoring force, corresponding to deformation quantity; a second vibrating part connected to the other end of the arm and a second elastic part producing the restoring force corresponding to the deformation quantity, a first actuator (2a), the displacement end (21a) of which comes into contact with the first force point on the positioning side of the second vibration part of two-force points holding a fulcrum part (14); and a second actuator (2b), the displacement end (21b) of which is brought into contact with the second force point on the positioning side of the second vibrating part of two force points. The displacement end of the first actuator and the displacement end of the second actuator are changed by the same displacement quantity in the reverse direction, while the displacement ends of the first and second actuators are brought into contact with the arm, to apply load to two test pieces (S).
