PROBLEM TO BE SOLVED: To control the urging force of a support portion for urging a workpiece in response to the urging force applied to the workpiece from a grindstone or the like, which changes according to the machining state of the workpiece, and to reduce the cost. Provided is a method for controlling a steady rest device, a grindstone provided with a steady rest device, and a steady rest device. SOLUTION: A steady rest device 10 works a support portion 20, a piston portion 32, and a piston portion 32 and a support portion 20 with an urging force F corresponding to a predetermined flow rate Q when a fluid having a predetermined flow rate is supplied. A cylinder device 30 including a rear urging chamber 33 for urging in a direction toward the outer peripheral surface Wa of the object W, and a fluid supplied from the fluid supply device 80 is adjusted to a predetermined flow rate Q to be rearward of the cylinder device 30. It includes an active flow rate control valve unit 40 supplied to the urging chamber 33, and a control device 70 that controls the active flow rate control valve unit 40 based on a control command value t corresponding to a predetermined flow rate Q.
