<p>In a force increasing device of a clamping device for an indexing table, a large clamping force is obtained without reducing working efficiency of a workpiece and while limiting the length in the axial direction of a rotating shaft. In a force increasing device 3 of a clamping device for an indexing table that increases a pressing force of a moving member 5 by a plurality of rolling bodies 10 guided by a first guide surface 6 and a second guide surface 8, at least one of the first guide surface 6 and the second guide surface 8 is formed by a guide region for the rolling bodies 10 corresponding to a former moving process part of the moving member 5 and a guide region for the rolling bodies 10 corresponding to a latter moving process part, and a moving speed of the rolling bodies 10 in a pressing direction (degree of speed reduction of the rolling bodies 10 with respect to the moving member 5) is changed by the guide region corresponding to the former process part and the guide region corresponding to the former part.</p> |
