置。[Scope of Claim for Utility Model Registration] (1) A clamp cylinder that reciprocates the clamp body in the direction toward and away from a reference member on which a work is placed, a plurality of cylinders arranged in parallel to the clamp body, and a bottom portion of each cylinder. a communication hole that communicates with each other;
The piston has a top that comes into contact with the workpiece during clamping, and is retractably inserted into the cylinder, and hydraulic oil that fills the cylinder and communication hole and acts on the base end of the piston. In a clamping device that moves the main body in a direction approaching a reference member and clamps a workpiece between the top of the piston and the reference member, a hydraulic circuit for the clamp cylinder supplies hydraulic oil from a hydraulic oil supply source to the clamp cylinder, and a hydraulic circuit for the clamp cylinder. It is equipped with a piston operating hydraulic circuit that branches off from the hydraulic circuit and connects to a communication hole provided in the clamp body, and a check valve that is provided in the piston operating hydraulic circuit and closes when clamping and opens when unclamping. A clamp device characterized by: (2) The clamp device according to claim 1, wherein the piston operating hydraulic circuit includes an accumulator branched from the piston operating hydraulic circuit between the clamp body and the check valve, into which a portion of the hydraulic fluid flows during clamping.
