In a rotary tool holding device that grips the shank of a rotary tool by utilizing the elastic deformation of an inner cylinder caused by the fluid pressure, is the hollow chamber oriented in the axial direction? The chamber is divided into three or more small chambers in the circumferential direction, and these small chambers have a plurality of small chambers that are interconnected by small gaps or small holes that allow fluid to leak from each other. a rotary tool holding device, the rotary tool holding device comprising: a forward pressure supply device communicating with at least one of the communicating small chambers; ″
