Abstract
A chuck device having a pair of arms rotatably supported by arm shafts and an operation member. One of the arms is provided with a roller shaft rotatable together with the arm about one of the arm shafts. The other arm is provided with an arm drive portion rotatable together with the arm. The arm drive portion is biased so as to press a second roller. Between the operation member and the roller shaft is provided a motion input mechanism for converting the motion of the operation member to rotational motion of the roller shaft about the arm shaft as the center of rotation. Between the roller shaft and the arm drive portion is provided an interlock mechanism that causes the arm drive portion to rotate about the arm shaft in conjunction with the motion of the roller shaft about the arm shaft as the center of rotation.
