Claims

[Scope of utility model registration request]

A clamp arm member is provided with a clamper that comes into contact with the workpiece, and is rotatably supported on a bracket erected on the base, and includes a release arm extending downward from the pivot portion, and a side opposite to the clamper with respect to the release arm. At the same time, an arm drive section is provided at the tip of a piston rod that goes in and out of a cylinder fixed to a base, etc., and this arm drive section is installed between the drive arm of the clamp arm member and the release arm. Further, the extension line of the contact surface of the drive arm with respect to the arm drive unit during clamping and the axis of the cylinder converge in the direction of movement of the arm drive unit during clamping. A booster holding device.
