たピストンロツドの中央部に、進退杆の受圧面を
加圧する三角形鰭状で側面を扁平な押圧面に形成
した押圧杆を、一対の進退杆のＸ形交差位置に更
に交差させて本体上に進退自在に設けて成る工作
物の自動振れ止め保持装置。 A pair of retractable rods having a roller pivotally supported at the tip of a bent rod, a concave portion not provided in the center of the base side of the rod, and a side surface of one convex portion facing the concave portion being obliquely cut off to form a pressure receiving surface. The recesses of the retractable rods are slidably inserted into grooves provided in the main body so as to cross in an X shape, with the concave portions of the retractable rods facing each other, and each retractable rod is biased in the direction of protruding from the main body. A pressure rod with a triangular fin shape and a flat side surface that presses the pressure-receiving surface of the retraction rod is placed in the center of the piston rod with a roller pivotally supported at its tip, at the X-shaped intersection of the pair of retraction rods. An automatic steady rest holding device for a workpiece, which is further provided intersectingly on the main body so as to be movable forward and backward.
