PROBLEM TO BE SOLVED: To provide a modified MR fluid having a relative specific gravity smaller than that of the conventional MR fluid, and exhibiting a large gripping force (shear strength) when used in a gripper or the like, and to provide a grip mechanism and a gripping device using the modified MR fluid.SOLUTION: A modified Magneto Rheological Fluid (MR fluid) 11 enhances the holding strength at the time of magnetization, by mixing a nonmagnetic powder 26, larger than the size of the ferromagnetic fine particles 25 and having a specific gravity smaller than that of the ferromagnetic fine particles 25, to a MR fluid 27 having a base liquid, and the ferromagnetic fine particles 25 existing in the base liquid in dispersed state.SELECTED DRAWING: Figure 5 |
