Abstract
An electric clamp apparatus includes a body, a rotary drive unit which is driven rotatably by an electric signal, and a rotary body rotated under a driving action of the rotary drive unit. Gear teeth of a clamp arm are enmeshed with helical screw grooves formed on the outer circumferential surface of the rotary body. The rotary body is rotated by driving the rotary drive unit, whereby the clamp arm, which is enmeshed with the screw grooves, is rotated through a predetermined angle to bring about a clamped state for clamping a workpiece.
