する振れ止め装置。 The steady rest main body includes a lower shoe that contacts the lower part of the workpiece rotatably supported, an upper shoe that contacts the workpiece above the lower shoe and supports the horizontal component force due to grinding resistance, and these lower shoes. and a feeding mechanism that causes the upper shoe to follow changes in the diameter of the workpiece, and a single-point contact type sizing device that is installed on the steady rest main body so as to be able to advance and retreat, and the swing rest is mounted on a base fixed on the table. A steady rest device in which a steady rest main body is guided so as to move forward and backward toward the work, wherein the steady rest main body is provided with a cylinder device for advancing and retracting the steady rest body and a cylinder device for advancing and retreating the sizing device; A fluid pressure circuit is provided within the steady rest main body to communicate the cylinder device for advancing and retracting the steady rest body with the cylinder device for advancing and retreating the sizing device, and to move the sizing device forward and backward in conjunction with the forward and backward movement of the steady rest main body. A distinctive steady rest device.
