Claims

[Scope of utility model registration request]

The cylinder body of the cylinder device is held in a holder, and a clamp arm is connected to the tip of the piston rod of the cylinder device via a toggle mechanism attached to the holder, and the clamp arm is opened and closed by the extension and contraction movement of the piston rod. In a movable clamp device, the holder is formed into an inverted U-shaped cross section consisting of an upper plate portion and left and right side ends that are integrally bent from both left and right ends of the upper plate portion and hang down, and the inside of the left and right side plate portions are bent. A roller guide groove parallel to the axis of the piston rod is provided on the side surface, and the clamp arm or a crank that rotates together with the clamp arm is pivotally mounted between the left and right side plate parts, and one end of the link is attached to the clamp arm or crank. At the same time, the other end of this link and the tip of the piston rod are connected by a roller pin, and left and right rollers that fit into the left and right roller guide grooves and roll are attached to both ends of the roller pin. A clamping device characterized by being pivotally supported.
