A crosshead 4 is screwed into a pair of rods (not shown) erected inside the connecting post 2, and the crosshead 4 is raised and lowered by rotation of the rods.

置決めを行うためである。Each roller holder is screwed onto the outer wall of the bearing guide 6 by a bolt 42 through a long hole HL (FIG. 1(b)) provided at the other end, and thereby the pair of rollers 3
1 and 32 are held directly below the upper grip 8 as shown. These rollers 31 and 32 are for pinching and restraining the test piece TP at approximately the middle position to form a fulcrum P when bending the test piece TP, and the holes HL of each roller holder are elongated holes. The reason for this is to position the rollers 31 and 32 in the vertical direction.

モータ２１の駆動力により回転可能である。On the other hand, a motor 21 and a rotating load frame holder 22 are fixed on the table 1, as shown in FIG. 1(b), and a pulley 23 is attached to the output shaft 21a of the motor 21. A rotating shaft 25 with a pulley 24 attached to one end thereof rotatably passes through the upper part of the holder 22 via a bearing 41, and a timing belt 26 is wound around the pulleys 23 and 24. Therefore, the rotating shaft 25 is
It can be rotated by the driving force of the motor 21.

Both ends of a semi-cylindrical rotating load frame 28 having a radius R are fixed to both ends of the frame 7, respectively. Therefore, the rotation of the rotating shaft 25 causes the bar 27 and the rotating load frame 28 to rotate together in the A direction and the B direction shown in FIG. 1(a). A lower grip 29 is attached to the center of the rotating load frame 28, and when the bar 27 is horizontal as shown in FIG. 1(a), the axes of the lower grip 29 and the upper grip 8 are coincides with the load axis. Both ends of the flat test piece TP are gripped by both grips 8°29.
次に、実施例の動作を説明する。Next, the operation of the embodiment will be explained.

付け、試験片ＴＰを折曲げるための支点Ｐを形成する。In carrying out the tension/bending test, the test piece TP is mounted on the testing machine without the rollers 31 and 32 attached. That is, the test piece 'rP is gripped by the upper and lower grips 8 and 29 with the lower grip 29 in the position shown by the solid line in the figure (a position facing the upper grip 8). Next, rollers 31 and 32 are attached to form a fulcrum P for bending the test piece TP.

（第１図（ｂ））上で試験片ＴＰを挟持させる。34r is positioned and attached to the bearing guide 6, and the center line of the rotating shaft 25 is adjusted by a pair of rollers 31 and 32.
(FIG. 1(b)) The test piece TP is held between them.

用する引張荷重はロードセル５により検出され、その検
出結果に基づいて例えば荷重一定試験などが行われる。In this state, when a pair of screw rods (not shown) are rotated to raise the crosshead 4, a tensile load is applied to the test piece TP via the upper grip 8, causing the test piece TP to elongate. Since the pair of rollers 31 and 32 rotate according to the elongation, elongation of the test piece TP is not hindered even if it is held between the rollers 31 and 32. Here, the tensile load acting on the test piece TP is detected by the load cell 5, and based on the detection result, for example, a constant load test is performed.

具２９の揺動により試験片ＴＰに折曲げ荷重が働き、試
験片ＴＰは支点４回りに折■がる。When the motor 21 is rotated by a predetermined amount in a predetermined direction when this tensile load is applied, the rotation of the pulley 23 attached to the output shaft 21a is transmitted to the pulley 24 via the timing belt 26, and the rotating shaft 25 is rotated. As a result, the bar 27 and the rotary load frame 28 are rotated, for example, by a predetermined amount in the direction of the hole shown in FIG. . This swinging of the lower grip 29 applies a bending load to the test piece TP, causing the test piece TP to bend around the four fulcrums.
この状態でモータ２１を上述とは逆方向に回転させると

第１図（、）のＢ方向に所定量だけ回転し、下部つかみ

折曲がる。このようにモータ２１を正逆方向に繰返し回
転させて試験片ＴＰを両方向に折曲げる。When the motor 21 is rotated in the opposite direction to that described above in this state, the bar 27 and the rotating load frame 28 are rotated by a predetermined amount, for example, in the direction B in FIG. By swinging in the opposite direction, the test piece TP is bent in the opposite direction to that described above. In this way, the test piece TP is bent in both directions by repeatedly rotating the motor 21 in the forward and reverse directions.

御するといった試験方法も可能である。Alternatively, the bending load may be applied by driving the motor 22 while the crosshead 4 is stopped. In this case, as the test piece TP is bent, a tensile load acts on the test piece rP, but this is detected by the load cell 5,
For example, a test method in which the motor 21 is controlled so that this tensile load is constant is also possible.

ーラ保持具３３ｆ、３３ｒ、３４ｆ。In the configuration of the above embodiment, the rod and crosshead 4 serve as a tensile load mechanism, and the rollers 31, 32 and roller holders 33f, 33r, 34f.
３４ｒが拘束部材を、モータ２１．プーリ２３゜２４、
