Abstract: 본 발명은, 1쌍의 쐐기현상죠우에 의해 시험편을 잡아쥐는 재료시험기용의 쐐기식척장치에 관한 것으로, 부하축을 따라서 입구쪽으로부터 안쪽에 걸쳐서 서서히 넓어지는 공간부로 형성하도록 내면에 쐐기면이 형성된 척프레임과, 상기 공간부에 수용되어 상기 척프레임의 이동에 의해 개폐되는 1쌍의 정치식 쐐기형상 죠우를 구비한 쐐기식척에 있어서, 상기 척 프레임을 상기 죠우에 대해서 부하축방향으로 승강시키는 승강수단과, 이 승강 수단에 구동력을 입력하기 위한 모우터와, 이 모우터의 출력을 감속해서 승강수단에 전달하는 감속수단을 구비한 것을 특징으로 하는 소형이고도 큰 잡아쥐는 힘을 얻을 수 있고 또한 조작성이 양호한 쐐기식 척을 제공하는 것이다.
