Abstract
An electric clamp apparatus includes a body, a rotary drive unit which is driven rotatably by an electric signal, and a clamp arm disposed rotatably with respect to the body. By driving the rotary drive unit, a drive force is transmitted to the clamp arm through a drive force transmission mechanism, whereby the clamp arm is rotated via a link arm through a predetermined angle with respect to the body, and a workpiece is clamped between the clamp arm and a support member of the body. Further, rotational operation of the clamp arm is regulated by abutment of a sub-roller against an inclined portion of a displacement body.
