Figures 1 and 3 are partially cutaway side views of the clamp device of the present invention, with Figure 1 showing the state in which hydraulic pressure is not applied to the cylinder device, and Figure 2 showing the state in Figure 1. Figure 3 shows a state where the piston is moved back by hydraulic pressure from the machine and the clamp arm is rotated horizontally. Figure 3 shows the state in which the piston is further retreated from the state shown in Figure 2 and the workpiece is clamped by the clamp arm. FIG. 4 is a partially cutaway view showing the spiral groove of the spindle, and FIG. 5 is a sectional view of a conventional clamp device.
