Claims (4)
- 탭을 유지하는 척과, 그 척이 회전 축심을 따라 이동 가능하게 되고 또한 그 척과 동기 회전하도록 상기 척을 유지하는 홀더 본체를 구비함과 아울러,
상기 탭에 대하여 상기 회전 축심 방향을 따라 인장력 또는 압축력이 작용했을 때에 상기 척과 상기 홀더 본체 사이에서 변형하는 탄성 변형체를 인장 방향과 압축 방향 각각에 구비하고,
상기 인장 방향 및 상기 압축 방향에 배치된 상기 탄성 변형체 중 적어도 어느 한쪽의 탄성 변형체에서 발생하는 상기 회전 축심을 따른 변형량은 상기 척이 상기 회전 축심을 따라 변위하는 양보다 적어지는 상기 탄성 변형체의 변형 저감 기구를 갖는 것을 특징으로 하는 탭 홀더. - 제 1 항에 있어서,
상기 척이 상기 홀더 본체에 대하여 상기 인장 방향 또는 상기 압축 방향으로 변위했을 때에 어느 한 방향에 있어서 상기 척과 상기 홀더 본체 사이에 복수의 탄성체를 직렬로 배치 가능하게 함으로써 상기 변형 저감 기구를 구성하고 있는 것을 특징으로 하는 탭 홀더. - 제 1 항에 있어서,
상기 홀더 본체와 상기 척 사이에 개재되는 통 형상의 부재이고, 상기 회전 축심의 방향으로 작동시키는 복수의 볼 부재를 상기 홀더 본체의 내면과 상기 척의 외면에 접촉시키고 상기 회전 축심에 대한 둘레 방향을 따라 설치된 리테이너에 의해 상기 변형 저감 기구를 구성하고 있는 것을 특징으로 하는 탭 홀더. - 제 1 항에 있어서,
상기 변형 저감 기구를 구성하는데, 상기 탄성 변형체와 접하는 상기 척의 수압면 및 상기 홀더 본체의 수압면 중 어느 한쪽의 수압면을 상기 회전 축심에 대하여 직교시키고, 다른 한쪽의 수압면을 상기 회전 축심의 방향을 향해서 경사지게 하고 있는 것을 특징으로 하는 탭 홀더.
