As described above with reference to FIGS. 9 and 10, for example, when end face machining and inner diameter machining of a motor frame are performed, the work rest 31 supports the work 10 so that the back surface side Since machining cannot be done, the machining must be stopped and the work piece turned over in order to process the back side. In addition, since the work is held by separate vices 32 using the handles (not shown), the work is eccentrically held and the tightening force is not uniform. Therefore, the work may scatter during deformation or machining. However, there is a problem that the workpiece vibrates due to cutting resistance during machining and machining abnormality occurs. The present invention provides a clamp device having a simple structure that solves the above-mentioned problems.
