MOVABLE BODY CLAMPING DEVICE

PURPOSE:To provide a movable body clamping device that is able to clamp a movable body with certainly, an little in displacement but large in rigidity against external force, and besides, and besides, comes to be optimum for such a clamp as requiring high accuracy and rigidity in the slide clamp or the like of a work rest in particular. CONSTITUTION:A pair of linear guide rails 2 is laid down on a fixed side slide member 2, installing two linear guides 5 and 6 at the side of a work rest structure 4, and these linear guides 5 and 6 are mounted on the paired linear guide rails 3, thereby installing the work rest structure 4 shiftably on the fixed side slide member 2, and then two clamp shoes 12 and 14 are installed at the side of the work rest structure 4 after making them come nearer to the linear guide rails 3. In addition, a clamp operating mechanism 16, making the clamp shoes 12, 14 come into contact with the linear guide rails 5 and 6 from both the upper and front sides under pressure by dint of clamp operating force, is installed in this work rest structure 4.
