Abstract
An electric clamp apparatus includes a body, a rotary drive unit which is driven rotatably by an electric signal, a drive force transmission mechanism for transmitting a rotary drive force of the rotary drive unit to a toggle link mechanism, 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 the drive force transmission mechanism, whereby the clamp arm is rotated 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. At this time, an adjustment mechanism disposed on the clamp arm includes a rod, which advances and retracts so as to stably clamp workpieces of different plate thicknesses.
