<p>A clamp apparatus (10) includes a pair of first and second clamp arms (14, 16). A driving force transmission mechanism (20) transmits a driving force of a drive unit (18), whereby the first clamp arm (14) is operated to rotate via a link arm (104), while simultaneously, the second clamp arm (16) is rotated, and after being rotated through a predetermined angle, under moving action of a roller (102), which is inserted into a cam groove (64) of a link plate (56), rotation of the second clamp arm (16) is stopped and maintained in advance with respect to the first clamp arm (14). Consequently, after positioning of a workpiece has been carried out by the second clamp arm (16), rotation of which is stopped, the first clamp arm (14) continues to be rotated, whereby the workpiece is clamped.</p> |
